About SenseCalc
Free UK calculators that are actually up to date.
What is SenseCalc?
SenseCalc is a free UK calculator tool covering employment, tax, retirement, legal and property calculations. Every calculator uses the latest HMRC rates, updated each April when the new tax year begins, so you always get figures you can actually rely on.
Why we built it
Most UK calculator sites either show outdated rates, make you register, or bury the answer behind pages of marketing copy. SenseCalc is different: type in your numbers, get your answer instantly, no sign-up required. We built the site we wished existed.
How we keep rates accurate
All statutory rates, national living wage, SSP, SMP, income tax thresholds, NI rates, dividend tax rates and more, are stored in a single source file and updated within 24 hours of HMRC publishing the new tax year rates each April. Every calculator on the site pulls from this central file, so when we update one number, every page updates automatically.
Rates for 2026/27 are confirmed from GOV.UK and HMRC. The most recent update was 6 April 2026.

Important limitations
SenseCalc calculators are tools for guidance, not professional advice. Results are estimates based on the information you provide. Individual circumstances, tax codes, benefit entitlements, contractual terms, legal case specifics, can significantly affect the real-world figure. Always verify important calculations with HMRC, a qualified accountant, solicitor or regulated financial adviser before making decisions based on them.
