About The Salary Calc

The Salary Calc is a free calculator site covering UK and US tax, salary, mortgages, property and personal finance. There are no accounts to create, no subscriptions and nothing to download. You put numbers in, you get an answer. That is it.

We built it because most financial calculators either hide behind paywalls, push you towards a product, or give you a number with no explanation of where it came from. Ours show you the working.

Every calculation runs in your browser. Nothing gets sent to a server. We do not store what you type, we do not sell data and there are no cookies beyond what AdSense requires. Close the tab and it is gone.

UK tools use HMRC 2026/27 rates — income tax bands, National Insurance thresholds, stamp duty, pension annual allowances. US tools use IRS 2026 figures. We update at the start of each tax year. If you spot something out of date, let us know.

These tools give you a solid estimate, not a guarantee. For anything significant — a mortgage, a tax return, a pension drawdown — speak to a qualified adviser.
