Free UK tax estimator that combines PAYE and self-employment income to show your estimated Income Tax, National Insurance, student loan repayments, pension contributions and net cash position — all in one place. No sign-up required, and your figures stay in your browser.
Hi Product Hunt 👋
I built UK Tax Estimator because I wanted a simple way to see PAYE and self-employment income together rather than calculating each separately.
The tool gives you an estimated breakdown of Income Tax, National Insurance, student loan repayments and pension contributions, along with your overall net cash position.
It’s free to use, requires no account, and your financial figures stay in your browser.
This is an estimator rather than tax or financial advice, and I’m continuing to improve it.
I’d really appreciate your feedback — particularly on what would make the calculator more useful for people with multiple sources of income.
Thanks for checking it out!
