Translation Word Count Calculator
Estimate translation cost and time from word count, language pair, and rate per word. Enter values for instant results with step-by-step formulas.
Formula
Total Cost = (Word Count x Rate Per Word + Word Count x Proofreading Rate) x Rush Multiplier
Where Word Count is the total number of source words, Rate Per Word is the translator charge per word, Proofreading Rate is the cost per word for review, and Rush Multiplier applies surcharges for expedited delivery (1.0 = standard, 1.5 = 50% rush surcharge).
Worked Examples
Example 1: Standard Business Document Translation
Problem: Translate a 5,000-word business report from English to Spanish at $0.12/word with proofreading at $0.03/word and standard delivery.
Solution: Translation cost = 5,000 x $0.12 = $600.00\nProofreading cost = 5,000 x $0.03 = $150.00\nRush multiplier = 1.0x (standard)\nTotal cost = ($600 + $150) x 1.0 = $750.00\nEstimated time = 5,000 / 250 wph = 20 hours (2.5 days)
Result: Total Cost: $750.00 | Time: 20 hours (~2.5 working days) | 20 pages
Example 2: Rush Legal Document Translation
Problem: Translate a 12,000-word legal contract from English to Japanese at $0.22/word, proofreading at $0.05/word, with 1.5x rush surcharge.
Solution: Translation cost = 12,000 x $0.22 = $2,640.00\nProofreading cost = 12,000 x $0.05 = $600.00\nSubtotal = $3,240.00\nRush surcharge = $3,240 x 0.5 = $1,620.00\nTotal cost = $3,240 x 1.5 = $4,860.00\nEstimated time = 12,000 / 250 = 48 hours (6 days)
Result: Total Cost: $4,860.00 | Time: 48 hours (~6 working days) | 48 pages
Frequently Asked Questions
How is translation cost calculated from word count?
Translation cost is typically calculated by multiplying the total word count of your source document by the rate per word charged by the translator. The per-word rate varies significantly depending on the language pair, subject matter complexity, and the translator's experience level. For example, common European languages like Spanish or French tend to have lower rates, while rare or complex languages such as Japanese, Korean, or Arabic command higher rates. Additional costs may include proofreading, formatting, and rush delivery surcharges. Most professional translation agencies quote based on source word count rather than target word count because it provides a predictable upfront estimate for clients.
What is a typical rate per word for professional translation?
Professional translation rates per word vary widely based on language pair and specialization. General translation for common European languages typically ranges from $0.08 to $0.15 per word. Technical, legal, or medical translations command higher rates of $0.15 to $0.30 per word due to the specialized knowledge required. Rare language pairs such as Finnish to Japanese or Icelandic to Arabic can cost $0.20 to $0.40 or more per word. Certified translations for legal documents often have a minimum fee plus a premium per-word rate. Machine translation post-editing services are generally cheaper at $0.04 to $0.08 per word but may sacrifice quality for certain content types.
How long does professional translation typically take?
A professional translator typically translates between 2,000 and 3,000 words per day for general content, which equates to roughly 250 to 400 words per hour of sustained work. Technical or highly specialized content may slow this rate to 1,500 to 2,000 words per day. Literary translation is even slower, sometimes only 1,000 to 1,500 words per day due to the creative effort involved. These estimates assume an 8-hour working day and include time for research and quality checking. For large projects, agencies may assign multiple translators to work in parallel, significantly reducing turnaround time while using translation memory tools to maintain consistency across the team.
What factors affect translation pricing beyond word count?
Beyond raw word count, several factors influence translation pricing significantly. Subject matter complexity is a major driver, with medical, legal, and technical translations costing 50 to 100 percent more than general content. File format matters because PDFs and scanned documents require additional formatting work. Turnaround time is critical, as rush jobs typically carry a 25 to 100 percent surcharge. The language pair rarity directly affects cost, with less commonly translated pairs being substantially more expensive. Certification and notarization for official documents add fixed fees. Desktop publishing, localization for software interfaces, and transcreation for marketing content all carry premium rates above standard translation.
How do I count words accurately for a translation quote?
Accurate word counting depends on your document format and the tools available. Microsoft Word and Google Docs have built-in word count features accessible from the tools or review menu. For PDF files, you can copy the text into a word processor or use specialized CAT (Computer-Assisted Translation) tools like SDL Trados, MemoQ, or Wordfast, which provide precise counts and can analyze repetition rates. Repetitions and fuzzy matches in translation memory can reduce costs by 30 to 70 percent for recurring content. For websites, use a web scraping tool to extract all translatable text. Remember to include text in images, charts, and embedded elements that may not appear in a standard word count but still require translation.
What is syllable count and how is it measured?
A syllable is a unit of pronunciation with one vowel sound. 'Cat' = 1 syllable, 'table' = 2, 'beautiful' = 3. Count vowel groups (a, e, i, o, u), subtract silent e at the end, and add back syllable exceptions. Syllable count per word is a key input in Flesch-Kincaid, Gunning Fog, and other readability formulas.
