Free, accurate UK financial calculators built by someone who got tired of sites that were either wrong, paywalled, or impossible to use on a phone.
I built EasyCalculators out of personal frustration. Every time I wanted to quickly check my take-home pay after a salary change, or work out the stamp duty on a house, I'd land on a site that was cluttered with ads, required me to sign up, or gave me numbers that didn't match what actually appeared in my bank account.
I'm based in the north of England, and the sites that existed were often built around London salary benchmarks and assumptions that didn't reflect how most people in the UK actually live and work. The Scottish salary calculator, for instance, was almost impossible to find — despite Scotland having an entirely different income tax system.
So I built my own. The goal was simple: type in a number, get an accurate answer, no friction.
Every calculator on this site is built from primary sources — the relevant HMRC guidance, gov.uk pages, and (for Scottish rates) the Scottish Government's published rate tables. We don't derive figures from other calculator sites. We go directly to the source.
The tax rates we use are:
Each calculator page includes an "Official sources" section linking directly to the relevant gov.uk page. We actively encourage you to verify the figures yourself.
We don't give personalised financial advice. We don't know your full tax situation, your individual PAYE coding notice, whether you have untaxed income, or how your employer handles certain benefits. Our calculators assume standard conditions (1257L tax code, no untaxed income, etc.) and flag when they do.
For anything that matters — a job offer, a house purchase, an inheritance — please also speak to a qualified accountant, financial adviser or solicitor. Our calculators are a quick sanity check, not a substitute for professional advice.
We also don't have advertising that influences what we say. The ads you see on this site are Google AdSense placements — Google decides what appears based on the page content and your browsing, not us. We are never paid to recommend specific products, providers or services in our editorial content.
EasyCalculators currently includes 16 free calculators:
We also publish in-depth guides covering the UK tax topics people search for most, including how to reduce your income tax, Scottish income tax explained, and the first-time buyer stamp duty rules.
If you've spotted an error in a calculator, have a suggestion for a new tool, or just want to say hello, use the contact page. We read every message.
We take accuracy seriously. If a rate is wrong, we want to know — and we'll fix it quickly.
