Translation Cost Calculator

A dedicated proofreading or editorial review after translation is itself a separate skilled pass requiring a second qualified reader, and the industry-typical premium for adding it runs around 30% on top of the base translation rate. Skipping the review lowers cost but leaves the translated text without an independent quality check before publication.

Not really — the Market Reach Multiplier applies a flat 10% bump per additional language as a simplification, but real market size varies enormously by language. Translating into a language spoken by hundreds of millions of readers typically opens far more revenue potential than a smaller regional language, even though both add the same 10% in this model.

It assumes a professional translator working at roughly 2,500 words per day, converts that into whole days needed for the total word count, and then expresses that in five-day work weeks. Faster turnaround is possible by splitting the project across multiple translators working the same language simultaneously, which this simple per-translator estimate doesn't model.

Days per Language describes how long a single language's translation takes on its own — it isn't automatically multiplied by the number of languages you're translating into. If one translator handles every language sequentially, the real project timeline is closer to that figure multiplied by the language count; translating languages in parallel with separate translators keeps the timeline closer to the single-language estimate.
