About Translation Turnaround Time Calculator

A professional translator manages 2000-3000 words a day. Twelve thousand words split between two translators takes 2.4 days, plus 0.72 days of review at 30%, giving 3.12 working days or about 4.4 calendar days including weekends. Splitting across translators speeds delivery but adds terminology reconciliation work.

Formulas

Translation days

days = words / throughput / translators

Total with review

total = translation days x (1 + review share)

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does adding translators halve the time?

Roughly, but consistency suffers. Beyond three or four translators the reconciliation effort starts to outweigh the speed gain.

Why is review 30% of translation time?

It is the standard TEP model allowance. Technical or regulated content often needs more, and raw machine output far more.
