Quick Answers
Are the calculators really free?
Yes — completely free, with no signup, no premium tier, and no usage limits. CalcKit is funded by unobtrusive advertising.
Are my financial inputs stored anywhere?
No. All calculations run in your browser. Your numbers are never sent to our servers, stored, or seen by anyone.
How often are rates updated?
We review all calculators after each UK Budget and update rates and thresholds at the start of each new tax year (6 April). We aim to update within 48 hours of any rate change.
Can I embed a calculator on my website?
We don't currently offer embeddable calculators, but it's on our roadmap. If this is something you need, get in touch and we'll add you to the notification list.
