About takehomepaycal.com
This site exists because every take-home pay calculator in the UK stops at a number, and a number is almost never the thing you actually wanted to know.
You did not open a calculator to find out what a payslip looks like. You opened it because you are deciding something: whether to take the job, whether the raise is worth the responsibility, whether you can afford the flat, whether to move, whether to drop a day. Every one of those questions needs the number and then something more.
So this site computes the number properly and then keeps going.
What it does not do
There is no email capture, no account, no adviser matching, and no affiliate row between you and the answer. Every calculation runs inside your own browser using JavaScript that ships with the page; nothing you type is transmitted anywhere, and you can disconnect from the internet after the page loads and it will still work.
That is not a marketing claim, it is a description of the architecture. There is no server to send anything to.
How the numbers are worked out
The engine implements the published HMRC and IRS rules rather than approximating them. National Insurance is calculated on the statutory period thresholds that real payroll uses. Student loan deductions are worked out per pay period and rounded down to whole pounds, as the rules require. US federal withholding follows Publication 15-T Worksheet 1A exactly, and the tables it reads are reconciled digit-for-digit against the statutory brackets by an automated test before every build.
The methodology page sets all of that out in detail, including the places where we are not certain.
Where we are uncertain, we say so
Some figures are not yet confirmed. The statutory School Teachers' Pay and Conditions Document for 2026 has not been published. Several US states have not reissued their withholding tables. Northern Ireland had not announced its Agenda for Change award at the time of writing.
In every one of those cases the page says so, in plain English, where you will see it. We do not fill a gap with a plausible-looking number, and we do not publish a pay scale we could not confirm from a primary source. A wrong salary is worse than no salary.
Corrections
If a figure here is wrong, we would rather hear about it than not. Get in touch and it will be fixed and rebuilt.
