If you’ve ever used or seen a CAT tool, like our translation platform, you know it almost literally looks like magic.
Every human translator needs some time to finish a translation project – and is limited to work on only one project at a time. This doesn’t mean that you’re not a capable and superior translator, but only that you’re a human – CAPTCHA-less verified.
But how to overcome those drawbacks of a human translator in order to run a successful international company which would be far ahead of its competition?
By finding yourself or your translator some help or something that isn’t a human… something like a CAT tool with Translation Memory (TM) in the back-end.
But What Exactly Is Translation Memory?
The raw definition would state that it is an infinitely expanding linguistic database of text segments, incorporated into a CAT tool, where saved units (text segments) present a broad range of everything from words and sentences to whole paragraphs.
We’re not talking about solo text fragments, but actual pairs of source and target text, which can be reused anytime during the translation process.
To understand how it benefits you, you first have to understand how it works.
How Does Translation Memory Work?
The UI won’t actually enable you to see the ingenious process happening behind the computer screen. But we can help you understand the fundamental principles without you being an IT master – by putting you in the role of the CAT, whereas your memory will serve as the translation memory.
Visualize your whole text as a string of beads where every word and punctuation has a unique shape and you know what every shape stands for. Like reading braille.
The Translation Memory Process (Simplified):
- First, we blindfold you and teach you how every single ever-existing or made-up word is ‘shaped’
- Then we ask you to glide from the very beginning to the end of the string, where you should identify as many paradigms as possible – you encounter how two words, three, four… words feel like if they are next to each other
- The more repetitions of gliding you make, the more you get familiar with the patterns
- You start to observe that some larger segments, sentences or paragraphs give you the same overall feeling – so they must convey the same or similar text
- You name one type of a paradigm with index A, another one as B… and sovereignly replace the whole repetitive segment with ‘A’, ‘B’… – because in life you spare yourself time and nerves wherever you can. And time is money after all
- Other unique patterns will not be replaced by any index unless you’ve glided anytime before over an exact same paradigm and you recall the text within it
- The only thing you have to do is to remember what ‘A’ and ‘B’ mean in the source text string
Now you want to share the meaning of those segments to the global community, but you are fluent only in the source language, so you hire yourself maybe 189 translators, who would teach you what segment ‘A’ means in 189 languages.
You can remember ALL the meanings and use them anytime later – without confusing or forgetting words. The best thing is you’ll only need a translator once for every memorized segment, because why would they teach you two times – you save translator’s time and lower your expenses.
But some other segments are still very similar like A, but not exactly the same as 100% A, so you called them ‘98% A’ – because you’ll humbly let a translator deal with the missing 2%. You could say you did an approximate string matching.
A translator also tells you what other unique patterns stand for. You’ll remember all of them simultaneously for further usage. In the end, your mental database is filled with pairs of an index and its belonging meanings.
Feel tired already by just imagining the whole process? To have the capacity to handle information and the mental speed to operate like that. Because a CAT tool combined with Translation Memory can do all of that (except for the ‘translator’ part – they’re essential).
The advantages of utilizing it are already obvious, but let me clarify how Translation Memory can be beneficial for you.
#1 Time- and Money-Saving Algorithm
The more text you trust us with as a client, the more we can take out for you – it’s an investment with satisfactory ROI values.
Because translators don’t have to translate a certain segment twice and are, in general, faster and more productive, they will spend less time (according to this research by 86%) on your project – for what we grant you a TM discount.
Thus, our translators are more productive and have less editing to make. Learn more about Translation Memory savings.
#2 Eat, Sleep, Translate - Repeat? Avoid Repetition
When working for one company several times, certain words, phrases or paragraphs start to repeat within or between texts.
By CAT examination, TM can detect the repetition of certain text segments (as described above) regarding the previously translated texts or current translation project. The UI will retrieve the matching target text and then a translator just has to confirm it afterwards.
This is especially useful for:
- Generic texts and technical documentation
- Product descriptions and specifications
- Legal boilerplate and standard clauses
- Software UI strings and error messages
#3 Higher Quality and Consistency of Translations
The more text you upload to our translation platform, the more your personal Translation Memory expands and gets personalized, implying it adjusts itself to your text profiles.
If certain segments don’t have to be translated again from scratch several times, we can maintain a coherent style of your translations and a consistent multilingual appearance of your brand through the workflow.
Were you thinking about transforming your brand into multilingual but want to stick to your budget and get translations fast? Then don’t hesitate to contact us!
Frequently Asked Questions About Translation Memory
What is a translation memory and how does it actually save money?
Translation Memory (TM) is a database that stores every sentence, phrase, or segment you’ve ever translated — and automatically reuses them in future projects instead of paying to translate the same content twice. Here’s exactly how it works and why it’s one of the highest-ROI investments in translation technology.
What Translation Memory Is (Technical Definition):
Translation Memory is a structured database that stores pairs of:
- Source text segment (e.g., English sentence)
- Target text segment (e.g., French translation)
- Metadata (translator name, date, client, project, quality score)
How TM Works in Practice:
Step 1: Initial Translation (Building the TM)
- You upload a 10,000-word document for translation
- Translator translates each segment (sentence/paragraph)
- As they work, every approved translation automatically saves to TM database
- Result: 10,000 words translated + TM database with ~2,000-3,000 unique segments
Step 2: Future Translation (Leveraging the TM)
- 3 months later, you upload updated document (10,000 words, 40% unchanged from v1)
- TMS platform compares new document against TM database
- Finds 4,000 words (40%) that match 100% from previous translation
- Auto-populates those 4,000 words with stored translations
- Translator only works on 6,000 new/changed words
- Result: 40% less work = 40-60% cost savings
The Money-Saving Mechanism (Detailed Breakdown):
Match Categories & Pricing:
100% Match (Exact Reuse)
- What it is: Segment identical to previously translated text
- Translator work: Zero (just confirm accuracy in new context)
- Typical discount: 90-100% off (you pay $0-10% of full rate)
- Example: Product spec “Dimensions: 15cm x 10cm x 5cm” appears in 50 products
95-99% Fuzzy Match (Minor Edits)
- What it is: Segment almost identical with small differences
- Translator work: Minor edits (e.g., change one number or date)
- Typical discount: 50-70% off
- Example: “Available in 5 colors” vs. “Available in 7 colors”
85-94% Fuzzy Match (Moderate Edits)

- Without TM: ~$14,000 (translating all 25k-30k words 4 times)
- With TM: $3,000 + $937.50 + $1,455 + $1,200 = $6,592.50
- Annual Savings: $7,407.50 (53%)
Example 3: Legal/Compliance Docs (Extreme Repetition)
Initial Contract Template:
- 10,000 words (standard clauses + custom terms)
- Rate: $0.20/word (legal specialist)
- Cost: $2,000
Contract #2-10 (90% boilerplate reused):
- 10,000 words each contract
- 9,000 words (90%): 100% match → $0.02/word = $180
- 1,000 words (10%): Custom terms → $0.20/word = $200
- Cost per contract: $380 (81% savings vs. $2,000)
Annual Cost (10 contracts):
- Without TM: $2,000 × 10 = $20,000
- With TM: $2,000 + ($380 × 9) = $5,420
- Annual Savings: $14,580 (73%)
The Compounding Effect (Year-Over-Year ROI):
Year 1: Building Phase
- TM leverage: 10-25% (small database, growing)
- Savings: 15-30%
Year 2: Maturity Phase
- TM leverage: 40-60% (established content, regular updates)
- Savings: 35-55%
Year 3+: Optimization Phase
- TM leverage: 60-80% (mature database, high reuse)
- Savings: 50-75%
3-Year ROI Example (50,000 words/year):
- Year 1: $5,000 cost (baseline, building TM)
- Year 2: $3,250 cost (35% savings from TM)
- Year 3: $2,250 cost (55% savings from mature TM)
- 3-year total with TM: $10,500
- 3-year total without TM: $15,000
- Savings: $4,500 (30%) + time saved (~45% faster delivery)
Beyond Direct Cost Savings (Hidden ROI):
1. Consistency Savings (Reduced Revisions)
- Without TM: Same term translated 5 different ways → client requests revisions → costs 10-20% of project in rework
- With TM: Perfect terminology consistency from Day 1 → minimal revisions
- Savings: 10-20% fewer revision cycles
2. Speed Savings (Faster Time-to-Market)
- Without TM: Translator works at 2,000 words/day
- With TM (60% leverage): Translator works at 5,000 effective words/day (only translates 800 new words, confirms 1,200 TM matches)
- Result: 2-3X faster delivery → launch products/campaigns weeks earlier
- Revenue impact: Entering market 3 weeks earlier = $10k-50k additional revenue (depending on product)
3. Quality Savings (Fewer Errors)
- Without TM: Translator re-translates technical terms from memory → 5-10% error rate on complex terminology
- With TM: Stored approved translations → 1-2% error rate
- Result: Fewer support tickets, fewer compliance issues, higher customer trust
4. Scalability Savings (Volume Handling)
- Without TM: Adding 5 new languages = 5X the workload
- With TM: TM database reused across all 5 languages → each subsequent language 40-60% cheaper than first
- Example:
- English → French: $5,000 (builds TM)
- English → German: $3,000 (reuses EN-FR TM structure, less ambiguity)
- English → Spanish: $2,800 (further leverages patterns)
- Total: $10,800 vs. $15,000 without TM (28% savings on multi-language)
ROI Calculator (Simple Formula):
Annual Savings = (Annual Word Volume) × (Per-Word Rate) × (TM Leverage %) × (Discount Rate)
Example:
Annual Savings = 200,000 words × $0.10/word × 55% leverage × 90% discount
Annual Savings = $20,000 × 0.55 × 0.90 = $9,900 saved annuallyPayback Period:
- TM setup cost: Usually $0 (built automatically as you translate)
- TMS platform cost: $500-2,000/year
- Break-even: Month 1-3 (savings exceed any platform costs immediately)
Bottom Line: Translation Memory saves money by storing every translated segment and reusing it automatically in future projects — eliminating the cost of retranslating the same content. Typical savings: 30-70% long-term depending on content repetition. E-commerce catalogs and technical docs see highest ROI (60-80% savings), marketing content moderate ROI (35-50% savings), highly unique creative content lowest ROI (15-25% savings). The savings compound over time: Year 1 = 15-30%, Year 2 = 35-55%, Year 3+ = 50-75%. Beyond direct cost savings, TM delivers faster delivery (2-3X), perfect consistency (reduces revisions 80%), and easier scalability (40-60% cheaper per additional language).

How does Translation Memory work in practice with real translation projects?
Understanding the step-by-step workflow of how Translation Memory integrates into actual translation projects helps you maximize ROI and avoid common pitfalls. Here’s exactly what happens from project upload to final delivery.
The Complete TM Workflow (6 Phases):
Phase 1: Project Upload & TM Analysis
What happens:
- You upload source files (Word, PDF, XML, JSON, etc.) to Translation Management System
- TMS automatically analyzes files against your existing Translation Memory database
- System generates TM Analysis Report showing:
- Total word count
- Breakdown by match category (100%, 95-99%, 85-94%, new)
- Estimated cost based on TM leverage
- Estimated delivery time
Example TM Analysis Report:
Project: Product Catalog Update Q2
Source: English → German
Total Words: 15,000
Match Breakdown:
- 100% Match: 8,500 words (57%) → Discount: 90% → Cost: $85
- 95-99% Fuzzy: 2,000 words (13%) → Discount: 60% → Cost: $80
- 85-94% Fuzzy: 1,500 words (10%) → Discount: 30% → Cost: $105
- New Content: 3,000 words (20%) → Full Rate → Cost: $300
Total Cost: $570 (vs. $1,500 without TM = 62% savings)
Delivery: 2-3 days (vs. 5-6 days without TM)Why this matters: You know upfront exactly what you’ll pay and how much TM saves you. No surprises.
Phase 2: TM Pre-Translation (Auto-Population)
What happens:
- TMS automatically pre-fills all segments with TM matches
- 100% matches: Inserted automatically (translator confirms only)
- Fuzzy matches: Inserted as suggestions (translator edits)
- New segments: Left blank for translator to complete
What translator sees in CAT tool interface:
| Source (English) | Target (German) | Match | Status |
|---|---|---|---|
| ”Available in 5 colors" | "Erhältlich in 5 Farben” | 100% | Confirmed ✓ |
| “Available in 7 colors" | "Erhältlich in <5>7</5> Farben” | 98% | Edited ✓ |
| “This new premium model…” | [Empty] | 0% | Translated ✓ |
Translator workflow:
- Reviews 100% matches (confirms or flags if context changed)
- Edits fuzzy matches (updates numbers, dates, product names)
- Translates new segments from scratch
- Result: 70-80% of work is reviewing/editing vs. 100% translating without TM
Why this matters: Translator productivity increases 2-4X depending on TM leverage. More work done in less time = lower cost passed to you.
Phase 3: Translation with TM Assistance (Real-Time)
What happens:
- As translator works, TM provides real-time suggestions from database
- When translator completes a new segment, TM checks for similar existing translations
- Suggests relevant matches even if not detected in pre-translation analysis
- Translator can accept, edit, or ignore suggestions
Example real-time TM assistance:
- Translator types: “Ships within 3-5 business days”
- TM suggests (85% match): “Ships within 2-3 business days” → “Lieferung innerhalb von 2-3 Werktagen”
- Translator edits: “Lieferung innerhalb von 3-5 Werktagen” (changes numbers, keeps structure)
- Time saved: 60-70% vs. translating from scratch
Why this matters: Even segments not caught in pre-analysis benefit from TM, further increasing savings and consistency.
Phase 4: Automatic TM Update (Learning Loop)
What happens:
- Every segment translator completes or edits automatically saves to TM database
- New translations: Added as new TM entries
- Edited fuzzy matches: Updates existing entry OR creates new variation
- Metadata tagged: Project name, date, translator, quality score
Example TM database growth:
Before Project:
- TM entries: 45,000 segments
- Coverage: 55% average match rate
After Project:
- TM entries: 48,000 segments (+3,000 new)
- Coverage: 62% average match rate (for similar future projects)
Why this matters: TM gets smarter with every project. Year 1 = 30% leverage, Year 3 = 70% leverage. It’s a compounding asset.
Phase 5: Quality Assurance with TM Consistency Checks
What happens:
- QA reviewer runs automated consistency checks against TM
- Flags segments where translator didn’t use TM match (potential error or intentional improvement)
- Compares current translation against stored TM to ensure terminology consistency
- Identifies any segments where same source was translated differently within project
Example QA flag:
- Segment 145: “Customer support” translated as “Kundenbetreuung”
- Segment 892: “Customer support” translated as “Kundendienst”
- TM shows: 50 previous projects used “Kundenbetreuung” consistently
- QA action: Flag for review, likely change 892 to match TM standard
Why this matters: Catches inconsistencies before delivery. Without TM-based QA, same term could be translated 5 different ways across 100-page document.
Phase 6: Delivery & TM Export (Ownership)
What happens:
- Final translation delivered to you
- Updated TM database available for download (TMX file format)
- You own your TM — can export and use with any provider/tool
- TM statistics report shows database growth and value
Example TM Value Report:
Project Complete: Product Catalog Q2
TM Database Stats:
- Starting entries: 45,000 segments
- Ending entries: 48,000 segments (+6.7% growth)
- New unique translations added: 3,000
- Estimated future value: $2,400 savings/year (based on historical reuse rates)
Total Project Investment: $570
Immediate TM savings: $930 (vs. $1,500 without TM)
Future value of new TM entries: $2,400/year
**True ROI: 420% Year 1, 940% cumulative over 3 years**Why this matters: You’re not just buying translation — you’re building an asset that reduces costs forever. And you OWN it, not locked into one vendor.
Real-World Workflow Example: SaaS Company Product Update
Scenario: Quarterly product update, 20,000 words of help documentation (English → French, German, Spanish)
Q1 (Initial Translation - Building TM):
- Upload: 20,000 words × 3 languages = 60,000 words total
- TM Analysis: 0% matches (first time)
- Cost: 60,000 × $0.10 = $6,000
- Delivery: 8-10 days
- TM Built: 5,000 unique segments stored (English → FR/DE/ES)
Q2 (Update - Leveraging TM):
- Upload: 20,000 words (35% new features, 65% unchanged)
- TM Analysis:
- 100% match: 13,000 words (65%)
- New content: 7,000 words (35%)
- Pre-translation: 13,000 words auto-populated in seconds
- Translator work: Only 7,000 new words × 3 languages = 21,000 words
- Cost: (13,000 × $0.01) + (7,000 × $0.10) = $130 + $700 = $830 per language = $2,490 total
- Savings: 58% vs. Q1 ($6,000 → $2,490)
- Delivery: 3-4 days (60% faster)
Q3 (Update - Mature TM):
- Upload: 22,000 words (product growing, 75% overlap)
- TM Analysis:
- 100% match: 16,500 words (75%)
- Fuzzy match (95-99%): 2,000 words (9%)
- New content: 3,500 words (16%)
- Cost: (16,500 × $0.01) + (2,000 × $0.04) + (3,500 × $0.10) = $165 + $80 + $350 = $595 per language = $1,785 total
- Savings: 70% vs. baseline ($6,000 → $1,785)
- Delivery: 2-3 days
Annual Comparison:
- Without TM: $6,000 × 4 quarters = $24,000
- With TM: $6,000 + $2,490 + $1,785 + $1,650 = $11,925
- Annual Savings: $12,075 (50%)
- Time Saved: ~25 weeks → ~12 weeks (52% faster)
Common Workflow Mistakes (And How to Avoid Them):
Mistake 1: Not Reviewing 100% Matches
- Problem: Assume 100% match = always correct → miss context changes
- Example: “Save file” in software → “Save as PDF” in new feature (TM suggests old “Save file” translation, but context now different)
- Fix: Translator should confirm 100% matches, especially if context changed
Mistake 2: Accepting Low-Quality Fuzzy Matches
- Problem: Translator uses 75% fuzzy match as-is to save time → produces awkward translation
- Fix: Set minimum fuzzy match threshold (85%+) for auto-suggestions, require full review below that
Mistake 3: Not Cleaning TM Database
- Problem: TM accumulates bad translations over time → suggests incorrect matches
- Fix: Quarterly TM maintenance — remove outdated entries, consolidate duplicates, update terminology
Mistake 4: Using Generic TM Across Unrelated Projects
- Problem: Mix marketing copy TM with technical docs TM → tone/terminology conflicts
- Fix: Segment TM by content type or project (marketing TM, legal TM, technical TM)
Mistake 5: Not Exporting TM Regularly
- Problem: Rely on vendor to store TM → lose access if switch providers
- Fix: Export TMX file quarterly, store backup you control
Phase-by-Phase Efficiency Gains:
| Phase | Without TM | With TM | Efficiency Gain |
|---|---|---|---|
| Analysis | Manual quote, 1-2 days | Instant automated analysis | 95% faster |
| Pre-translation | 0% pre-filled | 60-80% pre-filled | 60-80% time saved |
| Translation | 2,000 words/day | 5,000 effective words/day | 150% faster |
| QA | Manual consistency checks | Automated TM consistency | 70% faster |
| Delivery | 5-7 days typical | 2-3 days typical | 50-65% faster |
Bottom Line: Translation Memory workflow transforms projects by automatically analyzing, pre-translating, suggesting, learning, and quality-checking translations based on your historical database. Real-world impact: 50-75% cost savings, 2-3X faster delivery, 90%+ terminology consistency.

Why use Translation Memory instead of just using AI translation or hiring translators without TM?
This is the million-dollar question: if AI translation is cheap/instant and human translators are accurate, why add Translation Memory complexity? The answer: TM is the force multiplier that makes both AI and humans dramatically better, faster, and cheaper — while neither works optimally without it.
