Frequently asked questions

How much does document translation cost?

Costs vary by language, typically corresponding to the cost of living in the target countries (for example, translation into Simplified Chinese is about a third of the cost of translation into Swedish). SimulTrans provides discounts based on repeated text by leveraging translation memory. Document formatting costs are typically calculated on a per-page basis.

Use this cost calculator to get an estimate based on an average language cost.

How long does document translation take?

Document translation projects can take between three days and three months, depending on word count and team size. Each translator usually translates about 2,000 words per day, and our translators work simultaneously so the number of target languages won’t impact your timeline.

We can accommodate almost any timeline by scaling your translation team. A typical team has three translators and two reviewers per language, while some projects have over 100 translators per language!
