Sumwisely makes UK pay calculators that are quick to use and easy to check.
Most pay calculators either hide how they work or bury you in options. We wanted something in between: a short form, a clear answer, and every number traceable to HMRC or gov.uk.
What we believe
- Show the source. Every rate links to the official page it came from. See how we calculate.
- Test everything. Our calculators share one set of rules checked by automated tests before anything changes.
- No sign-up, no email gate. Results are free and instant.
Who runs it
Results are general guidance, not financial or legal advice.
