Disclaimer

Last updated: September 2026. Please read this page carefully before using our calculators.

Educational information only

All content on TypeTestLab — calculators, articles, tables, and examples — is published for general educational purposes. It is not skill training advice and is not a substitute for a qualified professional. We are not qualified instructors, and no client or advisory relationship is created by your use of this Site.

Entries summarize general reference information and are written for education, not as a substitute for expert guidance specific to your situation.

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and published typing-education research as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure

TypeTestLab is funded by display advertising served through Google AdSense. Advertisers have no influence over our content, formulas, or editorial choices, and placement of an ad is not an endorsement.

Errors and corrections

If you spot an error, please email hello@www.typetestlab.app with the inputs you used. Verified corrections are published promptly.
