How to check a £40,000 salary
This salary sits in the middle of the basic rate band with a clear run before the next threshold, which makes it the least eventful place in the UK tax system and, for planning purposes, the easiest. A pay rise here costs the same as the last one did, and the same as the next one will, until the higher rate arrives. That is not true above or below: below, a student loan threshold may be crossed; above, the higher rate and then the allowance withdrawal both change the arithmetic sharply. If you want to understand what a bonus or an overtime run is actually worth, this is the salary level where the answer stays stable enough to reason about.
- 1Confirm the salary figure.
- 2Select your student loan plan and add the Postgraduate Loan if you have one.
- 3Enter your pension contribution and how it is taken.
- 4Use the marginal rate to work out what a bonus is worth, rather than dividing the headline figure.
FAQ
What is a bonus worth at this salary?
Take the marginal rate shown by the calculator and apply it to the bonus, provided the bonus does not push you over the next threshold. If it does, part of it is taxed at the higher rate — increase the salary field by the bonus amount and compare, which is more reliable than any rule of thumb.
Why is my monthly payslip not exactly a twelfth of this?
National Insurance is calculated per pay period rather than across the year, so uneven pay makes the monthly figures differ even when the annual total matches. Income Tax usually corrects itself through your tax code over the year; National Insurance does not.
Does the calculator cover Scotland?
No. Scotland sets its own Income Tax bands, and every figure here is for England, Wales and Northern Ireland. Using this page for a Scottish salary will give you the wrong answer, which is why the limitation is stated rather than left for you to discover.
