Translation & Localization Cost Calculator (2026)

Q: Does word count mean my source content or the translated content?

Use your source content word count. Translated word counts vary by language, some languages run 15 to 30 percent longer than English, but vendors almost always price against the source word count, which is what you can measure before translation starts.

A translation and localization cost calculator gives you a real budget number before you request quotes, based on your actual word count, a per-word rate and how many languages you plan to launch in. Enter those figures along with any flat per-language fee, such as a project management or minimum-order charge, and the tool returns both the cost per language and the full project total.

How per-word pricing works

Most professional translation is priced per source word, not per finished page, since word count is the one measure that stays consistent regardless of formatting. Rates vary by language pair and content complexity, typically landing between $0.08 and $0.20 per word for standard business content, with technical, legal or highly specialized text priced higher. Enter the rate your vendor quoted, or a market rate you're evaluating, to see the real cost against your content volume.

Why the flat fee changes small jobs the most

A flat per-language fee, covering setup, project management or a translator's minimum charge, has an outsized effect on short content and shrinks in relative impact as word count grows. Two thousand words at a $50 flat fee adds real cost per language; twenty thousand words barely notices it. Run the numbers both ways if you're deciding whether to translate more content per language or spread a fixed budget across more languages.

Planning a multi-language content launch

Multiply your per-language cost by the number of markets you're targeting to get the full localization budget, then compare that against the traffic and revenue potential of each market before committing. International SEO only pays off when the content is genuinely usable in the target language, so build translation cost into the plan from the start rather than treating it as an afterthought once hreflang tags are already in place.

Translation & Localization Cost Calculator: questions, answered

How accurate are typical per-word translation rates?

Rates vary widely by language pair, subject matter and vendor type. Machine translation with human review can run under $0.05 per word, while specialized human translation for legal, medical or technical content often exceeds $0.20 per word. Use a rate you've actually been quoted for the most accurate result.

Should I include proofreading and desktop publishing costs?

This calculator covers translation cost itself. If your vendor charges separately for proofreading, formatting or desktop publishing, add those as part of your flat fee per language, or run the calculator twice and add the totals together.

Does word count mean my source content or the translated content?

Use your source content's word count. Translated word counts vary by language, some languages run 15 to 30 percent longer than English, but vendors almost always price against the source word count, which is what you can measure before translation starts.

How many languages should I localize into first?

Start with the languages tied to your largest addressable markets or your highest-traffic countries in analytics. This calculator shows the cost side of that decision; pair it with your traffic and revenue data per country before locking in a launch list.

Is a flat fee always charged per language?

Not always, some vendors only charge flat fees below a minimum word count, or waive them for larger contracts. Set it to zero if your vendor prices purely per word.
