How to use this calculator
What this calculator does
Estimate machine translation charges from character volume and the cost of reviewing a portion of the translated words.
How to use it
Convert the workload to source words and expected billable characters. Enter the machine translation rate for your language pair and the share reviewed by a professional, using realistic reviewer throughput.
What the result means
A multilingual publishing workflow may be dominated by human linguistic review rather than API fees. This model assumes consistent average character lengths.

Actual AI costs depend on provider pricing, model choice, token usage, discounts, caching, retries, batching, tool calls, workflow design, and usage volume.
Scenario guidance
When to use this
Use for translating support material, product catalogs and multilingual learning content.
Example scenario
A publisher localizes a large educational knowledge base and quality-checks a fifth of the text.
Inputs that usually matter most
- Character billing definitions and word count
- Language-specific reviewer speed, wage and scope
Common mistake to avoid
Never assume all machine-translated material is publication-ready without assessment.
How to interpret the result
Human quality control can exceed the underlying API cost.
Educational scenario with editable values; vendor billing rules, quality and service levels can differ.
Formula
Characters per word, reviewer throughput and language-pair difficulty are estimates. Translation quality is not guaranteed by human-review percentage alone.
Worked calculation
One million words averaging six billable characters at $12 per million cost $72 for machine translation. Reviewing 20% at 1,000 words/hour and $35/hour adds $7,000; with $100 fees total is $7,172.
Frequently Asked Questions
Why are characters and words both entered?
Many services bill characters, while publishers plan workload in words. The conversion makes that assumption visible.
Can the review rate be zero?
A zero word-per-hour rate is invalid if a nonzero quantity needs human review; enter a realistic editing throughput.
