You’re running a translation agency. Your per-word rate is $0.12, and you’re paying freelancers $0.06. That’s a 50% gross margin - sounds healthy, right? The ATC/Nimdzi 2023 UK industry survey says the average gross margin for translation services is 49.5%, so you’re right on target.
Then you look at your bank account at the end of the month. The number doesn’t match the spreadsheet. Where did the money go?
It went into all the things that don’t show up in a simple “client rate minus freelancer rate” calculation: project management, QA, technology, rent, insurance, sales time, rework. These costs are real, they’re recurring, and they eat margins silently. Most agency owners know this intuitively but never sit down to calculate the actual per-word cost of running their operation.
This article walks through every cost category, shows you the math, and gives you two worked examples - one for a mid-size agency processing 200,000 words per month, and one for a smaller shop doing 50,000. By the end, you’ll know your true cost per word down to the third decimal.
Why gross margin lies¶
Gross margin in translation is deceptively simple. You charge the client $0.12/word, pay the translator $0.06/word, and the difference is yours. Fifty percent. Done.
Except it’s not done. That 50% has to cover everything else your business needs to function: the project manager who assigned the job, the QA reviewer who caught the mistranslated term, the TMS subscription (Translation Management System - the software that routes files between translators and tracks progress), the office where your PM sits, and the accountant who files your taxes.
The Slator 2025 Language Industry Market Report puts the global language services market at $31.7 billion. But here’s the sobering part: 25-41% of LSPs (Language Service Providers - companies that sell translation, interpreting, or localization services) reported revenue declines in 2024, depending on size tier. Boutique agencies - the smallest ones - were hit hardest, with an average of -3.7% growth.
In a market where a third of your competitors are shrinking, understanding your true cost structure isn’t optional. It’s the difference between surviving and joining that 41%.
“25% of Super Agencies, 33.3% of Leaders, 40% of Challengers, and 41% of Boutiques reported revenue declines in 2024.” - Slator 2025 Language Service Provider Index
“Margins for translation services ranged from 26% to 77%, and the average margin was 49.5%.” - ATC/Nimdzi 2023 UK Language Services Industry Report
That wide range - 26% to 77% - tells you something important. Agencies doing similar work with similar clients can have wildly different cost structures. The ones at 77% aren’t necessarily charging more. They’ve just figured out where the money leaks out and plugged the holes.
Direct costs: TEP rates by language pair¶
TEP stands for Translation, Editing, and Proofreading - the three-step process that most professional translation goes through. The translator does the first pass. An editor (a second linguist) reviews the translation against the source. A proofreader reads the final target text for grammar, style, and consistency.
Each step has its own per-word rate, and these rates vary significantly by language pair. Here’s what the market looks like for two common directions:
EN > UK/RU (English to Ukrainian or Russian)¶
| Step | Per-word rate |
|---|---|
| Translation | $0.05 - $0.10 |
| Editing | $0.02 - $0.04 |
| Proofreading | $0.01 - $0.02 |
| TEP total | $0.08 - $0.16 |
EN > DE (English to German)¶
| Step | Per-word rate |
|---|---|
| Translation | $0.08 - $0.14 |
| Editing | $0.03 - $0.06 |
| Proofreading | $0.02 - $0.03 |
| TEP total | $0.13 - $0.23 |
The difference is striking. Full TEP for a German project can cost almost three times what the same project costs in Ukrainian or Russian. That’s driven by supply (fewer qualified EN>DE translators relative to demand), cost of living in German-speaking countries, and client expectations around quality standards.
Most agencies don’t run full TEP on every project. General content might get translation plus editing (TE), skipping the proofreading step. That cuts direct costs by 10-15%. But specialized content - legal, medical, financial - almost always needs all three steps, because the cost of an error is too high.
Here’s the critical thing: these are your direct costs only. They don’t include a single dollar of overhead. If you’re charging $0.12/word for an EN>UK project and your full TEP costs $0.10/word at the mid-range, you’ve got $0.02/word left for everything else. That’s where most agencies start to bleed.
Project management - the invisible margin eater¶
Every translation project needs someone to manage it. That someone receives files from the client, analyzes them, selects the right linguists, creates the project in the TMS, sends instructions, monitors deadlines, handles client questions, chases late deliveries, does final checks, and sends the completed files back.
This takes time. And time costs money.
According to Glassdoor, the average salary for a Translation Project Manager in the United States is $84,649 per year. In Europe, the range is typically $3,500 - $5,000 per month ($42,000 - $60,000 per year). Let’s work with both numbers.
How much time does PM actually take?¶
Here’s a rough breakdown for a typical 5,000-word project:
| Task | Time |
|---|---|
| Client communication (receive brief, clarify questions) | 15-30 min |
| File analysis and preparation | 10-20 min |
| Linguist selection and assignment | 10-15 min |
| TMS setup (create project, set deadlines, upload files) | 10-15 min |
| Monitoring and follow-up during production | 15-30 min |
| Final QA check and delivery | 15-20 min |
| Invoicing and admin | 10-15 min |
| Total | 85-145 min |
Call it 2 hours on average per 5,000-word project. That’s 0.4 minutes per word, or about 24 minutes per 1,000 words.
Now let’s translate that into cost per word.
US-based PM ($84,649/year)
With benefits and employer taxes (add ~30%), the fully loaded cost is roughly $110,000/year. Assuming 1,800 productive hours per year (2,080 total minus vacation, sick days, meetings, training), that’s $61/hour.
At 2 hours per 5,000 words: $122 / 5,000 = $0.024/word for PM alone.
Europe-based PM ($48,000/year, mid-range)
Fully loaded: ~$62,400/year. At 1,800 hours: $34.70/hour.
At 2 hours per 5,000 words: $69.40 / 5,000 = $0.014/word for PM.
These numbers assume your PM is actually spending all their productive hours on billable projects. In reality, PMs spend significant time on internal meetings, training, dealing with IT issues, and other non-billable activities. A realistic utilization rate (the percentage of time spent on revenue-generating work) is 65-75%. If your PM is only 65% utilized, divide those per-word costs by 0.65 - making the US PM cost jump to $0.037/word.
“A project manager handles 40-60 concurrent projects and generates $80,000-$150,000 in monthly revenue.” - BusinessDojo Translation Agency Profitability Guide
That range tells you something about the scaling effect. If your PM handles $150K/month in revenue, their $9,200/month cost (US, fully loaded) is 6.1% of revenue. If they handle $80K/month, it’s 11.5%. Same PM, same salary - the difference is volume throughput.
QA costs - linguistic, automated, and managerial¶
Quality assurance in translation isn’t one thing. It’s at least three different activities, and each has its own cost profile.
Linguistic QA¶
This is the human review that catches errors the editor might have missed: terminology inconsistencies, style guide violations, formatting problems, incorrect number formatting, wrong date formats for the target locale. Many agencies have a dedicated QA reviewer or senior linguist do a final pass.
Typical rates for linguistic QA: $0.005 - $0.015/word, depending on complexity. For a 10,000-word project, that’s $50 - $150 in additional direct cost.
Automated QA¶
Tools like Verifika, QA Distiller, or built-in TMS checks run automated scans for common errors: missing tags, inconsistent terminology, number mismatches, untranslated segments. These tools are fast, but they produce false positives that someone still has to review.
The tool cost itself is covered in the technology section below. The human cost of reviewing automated QA reports is typically 15-30 minutes per 10,000 words, which adds another $0.003 - $0.006/word at PM rates.
Managerial QA¶
Someone needs to define quality standards, create style guides, review client feedback, track error rates per linguist, and decide when a translator should be removed from the team. This is usually done by a QA manager or senior PM.
For small agencies (under 100K words/month), this isn’t a separate role - it’s absorbed into PM duties, which means your PM cost per word is actually higher than the calculation above suggests. For mid-size agencies, a dedicated QA specialist costs $50,000 - $75,000/year.
Total QA cost per word¶
| QA type | Cost per word |
|---|---|
| Linguistic QA (human reviewer) | $0.005 - $0.015 |
| Automated QA review time | $0.003 - $0.006 |
| Managerial QA (allocated) | $0.002 - $0.005 |
| Total QA | $0.010 - $0.026 |
On a $0.12/word client rate, that’s 8-22% of revenue going to quality assurance. And if you skip it to save money, you’ll pay for it in rework - which costs even more (we’ll get to that in the traps section).
Technology stack - TMS, CAT, QA tools¶
Running a translation agency without technology is like running a logistics company without trucks. You need a TMS to manage projects, CAT tools (Computer-Assisted Translation tools - software that helps translators work faster by reusing previously translated segments) for your linguists, and QA tools to catch errors.
Here’s what the technology stack costs for a small to mid-size LSP:
Monthly technology costs¶
| Tool category | Monthly cost | Notes |
|---|---|---|
| TMS (Protemos, XTRF, Plunet) | $200 - $800 | Depends on user count and features |
| CAT tool licenses (Trados, memoQ) | $50 - $200 | Per seat; many freelancers have their own |
| QA tools (Verifika, Xbench) | $30 - $100 | Some bundled with CAT/TMS |
| All-in-one platform (Smartcat, Phrase) | $100 - $500 | Replaces separate TMS + CAT |
| Cloud storage and file sharing | $50 - $100 | Google Workspace, Dropbox Business |
| Communication tools | $0 - $50 | Slack, email hosting |
| Accounting/invoicing | $50 - $150 | QuickBooks, Xero |
| Total range | $380 - $2,200 | Depends on agency size and tooling choices |
Source: compiled from G2 TMS reviews, vendor pricing pages, and industry surveys.
Technology cost per word¶
Now let’s convert this to per-word cost:
| Monthly volume | Monthly tech cost (mid) | Cost per word |
|---|---|---|
| 50,000 words | $800 | $0.016 |
| 100,000 words | $1,000 | $0.010 |
| 200,000 words | $1,200 | $0.006 |
| 500,000 words | $1,800 | $0.004 |
Technology is a fixed cost. The per-word impact drops dramatically as volume increases. At 50,000 words/month, you’re paying $0.016/word just for tools. At 200,000 words/month, it’s $0.006. This is one of the biggest reasons why scale matters in this business - and why small agencies often have thinner margins despite charging the same rates.
SG&A - the costs everyone forgets¶
SG&A stands for Selling, General, and Administrative expenses. It’s the catchall for everything that keeps the business running but isn’t directly tied to a specific project.
Office and facilities¶
| Expense | Monthly cost |
|---|---|
| Office rent (small, non-metro) | $2,000 - $3,000 |
| Office rent (metro area) | $3,000 - $5,000 |
| Utilities and internet | $200 - $500 |
| Office supplies and equipment | $100 - $300 |
Remote-first agencies can slash this by 60-80%. If you’re running your agency from home or a co-working space, your facilities cost might be $200-$500/month instead of $2,500+. That’s a real competitive advantage that directly hits the bottom line.
Sales and marketing¶
Industry benchmarks put marketing spend at 10-15% of revenue. For a $30,000/month agency, that’s $3,000 - $4,500. This includes:
- Website hosting and SEO
- Content creation (blog posts, case studies)
- Paid advertising (Google Ads, LinkedIn)
- Conference attendance
- Sales team time (if you have one)
Don’t forget the cost of sales time even if you don’t have a dedicated salesperson. If the owner spends 20% of their time on sales calls, proposals, and follow-ups, that’s 20% of their salary allocated to sales.
Admin, legal, and insurance¶
These costs run 3-5% of revenue:
- Accounting and bookkeeping
- Legal fees (contracts, disputes)
- Professional liability insurance
- Business insurance
- Bank fees and payment processing
SG&A cost per word¶
| Category | % of revenue | At $0.12/word rate |
|---|---|---|
| Facilities (mid-range) | 5-10% | $0.006 - $0.012 |
| Marketing | 10-15% | $0.012 - $0.018 |
| Admin/legal/insurance | 3-5% | $0.004 - $0.006 |
| Total SG&A | 18-30% | $0.022 - $0.036 |
Remote-first agencies with lean marketing budgets can be at the low end. Agencies with physical offices in expensive cities and active advertising campaigns will hit the high end.
The formula - putting it all together¶
Here’s the formula for your true cost per word:
True cost/word = Direct costs (TEP) + PM cost + QA cost + Technology cost + SG&A cost
Or expressed as a percentage of the client rate:
Net margin = Client rate - True cost per word
Let’s run two real scenarios.
Scenario A: Mid-size agency, 200,000 words/month¶
Setup: - Client rate: $0.12/word - Monthly revenue: $24,000 - Language mix: mostly EN>Eastern European - Team: 1 full-time PM (Europe-based), 15-20 freelance linguists - Remote-first office
| Cost category | Per word | Monthly total | % of revenue |
|---|---|---|---|
| TEP (freelancers) | $0.065 | $13,000 | 54.2% |
| Project management | $0.016 | $3,200 | 13.3% |
| QA (linguistic + automated) | $0.012 | $2,400 | 10.0% |
| Technology | $0.006 | $1,200 | 5.0% |
| SG&A (remote, lean marketing) | $0.014 | $2,800 | 11.7% |
| Total cost | $0.113 | $22,600 | 94.2% |
| Net profit | $0.007 | $1,400 | 5.8% |
That’s a 5.8% net margin. Not great. The gross margin looked like 45.8% (rate minus TEP), but once you add everything else, there’s barely anything left. And this scenario assumes no rework, no unpaid rush hours, and 100% collection on invoices.
Scenario B: Same agency, 200,000 words/month, optimized¶
Changes made: - Negotiated slightly better TEP rates by offering consistent volume to top freelancers - Improved PM efficiency through better TMS automation (more templates, fewer manual steps) - Invested in MTPE for suitable content types (30% of volume), reducing TEP costs on those projects by 25% - Reduced SG&A by cutting an underperforming marketing channel
| Cost category | Per word | Monthly total | % of revenue |
|---|---|---|---|
| TEP (blended with MTPE) | $0.057 | $11,400 | 47.5% |
| Project management | $0.013 | $2,600 | 10.8% |
| QA (linguistic + automated) | $0.011 | $2,200 | 9.2% |
| Technology (added MTPE tool) | $0.007 | $1,400 | 5.8% |
| SG&A (optimized) | $0.012 | $2,400 | 10.0% |
| Total cost | $0.100 | $20,000 | 83.3% |
| Net profit | $0.020 | $4,000 | 16.7% |
Now we’re in the 15-20% net margin range that industry benchmarks from Nimdzi consider healthy for a well-run agency. The difference? $2,600/month in profit - $31,200/year - without changing the client rate by a single cent.
Scenario C: Small agency, 50,000 words/month¶
Setup: - Client rate: $0.12/word - Monthly revenue: $6,000 - Owner handles PM + sales + admin - Part-time QA reviewer - Home office
| Cost category | Per word | Monthly total | % of revenue |
|---|---|---|---|
| TEP (freelancers) | $0.065 | $3,250 | 54.2% |
| Project management (owner’s time, 40%) | $0.024 | $1,200 | 20.0% |
| QA | $0.010 | $500 | 8.3% |
| Technology | $0.016 | $800 | 13.3% |
| SG&A (home office, minimal) | $0.010 | $500 | 8.3% |
| Total cost | $0.125 | $6,250 | 104.2% |
| Net profit | -$0.005 | -$250 | -4.2% |
The small agency is losing money. Not because they’re bad at translation - they might be excellent. It’s because fixed costs (technology, PM time) don’t scale down proportionally with volume. The owner is essentially subsidizing the business with unpaid labor.
This is why scale matters so much. And it’s why many solo operators and small agencies survive by not counting their own time as a cost. The moment you value the owner’s hours at market rate, the numbers often go negative at low volumes.
5 traps that distort your calculations¶
Even if you’ve done the math above carefully, these five factors can make your real costs higher than your spreadsheet suggests.
1. PM utilization is lower than you think¶
Most agencies assume their PMs are working on billable projects 85-90% of the time. The real number is usually 65-75%. Internal meetings, email, training, dealing with problematic freelancers, onboarding new clients - all of this is time that doesn’t generate revenue but absolutely costs money.
If you’re using 85% utilization in your calculations, you’re underestimating PM costs by 13-24%.
2. Translation memory discounts eat your margin¶
TM (Translation Memory) is a database of previously translated segments. When a client sends repeat content, the TM matches segments that have already been translated. Most agencies offer discounts for these matches: 100% match = free or 10% of the full rate, fuzzy matches = 40-60% of the full rate.
The problem: your PM, QA, and technology costs stay the same regardless of whether a segment is new or a TM match. You’re discounting the client rate but not your overhead. On projects with 40-60% TM match rates, this can cut your effective margin in half.
3. Rush orders aren’t as profitable as they seem¶
You charge a 30-50% rush surcharge. Great. But rush orders also have hidden costs: - PM overtime (or the PM drops a regular project to handle the rush, delaying it) - Premium freelancer rates for last-minute availability - Higher error rates due to time pressure, leading to more QA time and potential rework - Disrupted workflow affecting other projects in the pipeline
Unless you’ve calculated the true all-in cost of rush delivery, that 30% surcharge might just be breaking even.
4. Free rework is the silent killer¶
Client says: “We changed our mind about the terminology - can you update these 47 files?” You do it because it’s a big client and you don’t want to lose the relationship. But that rework costs PM time, linguist time (usually at full rate if you want to keep your translator), and QA time.
Industry estimates put rework at 3-8% of total production volume for an average agency. If you’re not tracking rework hours and billing for them (or at least accounting for them in your pricing), you’re leaking margin.
5. Cost of sales is rarely counted¶
How much time does it take to win a new client? Between the initial inquiry, the test translation, the proposal, the negotiation, and the onboarding - you might spend 5-15 hours before the first billable word is translated. At a PM’s hourly rate of $35-$60, that’s $175-$900 per new client acquired.
If your average client sticks around for $2,000 in total revenue, that $900 acquisition cost is 45% of lifetime value. You need to spread that cost across all the words that client will send you.
How to calculate your cost per word - practical template¶
Here’s a step-by-step process you can follow right now with your own numbers.
Step 1: Calculate your monthly direct costs¶
Add up everything you paid freelancers last month. Divide by total words delivered. This is your actual average TEP cost per word.
Your TEP cost/word = Total freelancer payments / Total words delivered
Don’t use rate card prices - use actual payments. TM discounts, minimum fees, and negotiated rates mean the actual number often differs from the standard rate.
Step 2: Calculate your PM cost per word¶
Take your PM’s fully loaded monthly cost (salary + benefits + taxes). Multiply by their utilization rate. Divide by monthly word volume.
PM cost/word = (PM monthly cost x utilization rate) / Monthly word volume
If the owner does PM work, estimate the percentage of their time spent on PM activities and use their target salary (what they should be earning) as the base.
Step 3: Calculate your QA cost per word¶
Add up all QA-related costs: reviewer payments, time spent on automated QA review, quality management activities.
QA cost/word = Total QA costs / Monthly word volume
Step 4: Calculate your technology cost per word¶
Sum all technology subscriptions and divide by volume.
Tech cost/word = Total monthly tech spend / Monthly word volume
Step 5: Calculate your SG&A cost per word¶
Add up rent, utilities, marketing spend, admin costs, insurance, legal, accounting.
SG&A cost/word = Total monthly SG&A / Monthly word volume
Step 6: Add it all up¶
True cost/word = TEP + PM + QA + Tech + SG&A
Net margin/word = Client rate - True cost/word
Net margin % = Net margin/word / Client rate x 100
If your net margin is below 15%, you’ve got a problem. Either your rates are too low, your costs are too high, or your volume is too thin to cover fixed costs. All three are fixable, but you need to know which one (or which combination) is the issue before you can act.
Quick sanity check¶
Compare your result against these industry benchmarks:
| Metric | Healthy range | Warning zone |
|---|---|---|
| Gross margin (revenue minus TEP) | 40-50% | Below 35% |
| PM cost as % of revenue | 8-13% | Above 18% |
| Technology as % of revenue | 3-7% | Above 12% |
| Net profit margin | 15-20% | Below 10% |

FAQ¶
What’s a good net profit margin for a translation agency?¶
A well-run agency should be hitting 15-20% net profit margin after all costs are accounted for. Top performers - usually agencies with strong specialization, loyal clients, and good technology adoption - can reach 25-30%. If you’re below 10%, something in your cost structure needs attention. The most common culprits are PM overhead (too many hours per project), low volume (fixed costs spread too thin), and pricing that hasn’t kept up with cost increases.
How much do translation agencies mark up over freelancer rates?¶
The standard rule of thumb is that agencies charge at least 2x what they pay freelancers. So if you’re paying a translator $0.06/word, you’d charge the client $0.12/word or more. But as this article shows, that 2x multiplier doesn’t automatically mean healthy profits. After PM, QA, technology, and SG&A costs, the actual margin on a 2x markup can be as low as 5-8% if the agency isn’t managing overhead carefully. For specialized content (legal, medical), markups of 2.5x-3x are common and necessary to cover the higher QA requirements.
Why do translation agencies charge minimum fees?¶
Minimum fees - typically $50-$150 per project - exist because of fixed costs. Even a 50-word email translation requires a PM to receive the file, set up the project, assign a linguist, do a QA check, and deliver the result. That process takes 30-45 minutes regardless of word count. At a PM cost of $35-$60/hour, the agency needs at least $25-$45 just to cover PM time - before the translator is even paid. Without a minimum fee, small projects would be delivered at a loss every single time.
How does MTPE (Machine Translation Post-Editing) affect real cost per word?¶
MTPE replaces the human translation step with machine translation output that a human editor then corrects. This can reduce direct translation costs by 15-30% on suitable content types (general business content, product descriptions, support articles). But it doesn’t reduce PM or QA costs - in fact, QA costs can increase because machine output needs different types of checking. The net effect on total cost per word is usually a 10-20% reduction, not the 50-70% that MT vendors sometimes suggest. MTPE works best as part of a blended approach: use it for high-volume, lower-stakes content while keeping full human TEP for specialized or creative work.
What’s the biggest hidden cost in running a translation agency?¶
Project management, hands down. Most agency owners dramatically underestimate how much PM time each project consumes. The translation itself is visible - you pay the freelancer and see the invoice. But PM time is invisible. It’s spread across dozens of small tasks: emails, file prep, QA review, client calls, chasing deadlines. When you add it up, PM typically consumes 10-15% of revenue for a well-run agency and up to 20%+ for agencies with inefficient processes or high-touch clients. Tracking PM time per project for even one month usually reveals surprises.
How do I reduce my real cost per word without cutting quality?¶
Three approaches that work without sacrificing quality. First, increase volume - fixed costs (technology, SG&A) spread thinner as you process more words, so even a 20% volume increase can shift your net margin by 3-5 points. Second, improve PM efficiency through better TMS automation, project templates, and standardized workflows - agencies that invest in process typically cut PM time per project by 20-30%. Third, build a stable freelancer pool instead of constantly sourcing new linguists - onboarding and testing new translators is expensive (5-10 hours per linguist), and your best translators get faster and need less revision over time, directly reducing your editing and QA costs.
