Free UK tax and money calculators in one place

TaxFly brings together 172 free calculators covering the questions people actually ask about their money — from "what's my take-home pay?" to "how much stamp duty will I pay?" Every tool uses official HMRC rates, thresholds and allowances for the 2026/27 tax year, so the figures you see reflect the rules in force today rather than last year's numbers.

The most popular tools are our Income Tax Calculator and Take-Home Pay Calculator, which turn a gross salary into the amount that actually reaches your bank account after tax, National Insurance and other deductions. Homebuyers lean on the Stamp Duty Calculator and Mortgage Calculator, while business owners use the VAT Calculator and Corporation Tax Calculator.

Find the right calculator faster

Use the search box above to jump straight to a tool by name, or filter by category — tax, salary and income, pensions, property, savings, business and everyday money. Each calculator shows a clear, line-by-line breakdown of how the result is reached, so you can understand the maths rather than just trusting a single number.

Everything on TaxFly is free to use, works on any device and needs no account or sign-up. We never store the figures you enter. If you spot a calculator you would like us to add, get in touch — the directory grows based on what visitors ask for.

Official & accurate

Every figure follows HMRC 2026/27 rates and links to its gov.uk source.

Private & secure

Calculations run in your browser. Your figures are never stored or shared.

Free for everyone

No account, no paywall, no limits. All our tools are completely free.
