How your take-home pay is worked out
Your employer runs your pay through PAYE in a fixed order. Anything you sacrifice comes off your gross pay first. What is left is measured against your Personal Allowance, then Income Tax and National Insurance are worked out on the remainder, and any Student Loan is taken last. The calculator above follows the same order, which is why its figures agree with a payslip rather than a rule of thumb.
Two numbers matter and people usually only know one of them. Your effective rate is what the whole year costs you. Your marginal rate is what your next pound costs — and between £100,000 and the point your Personal Allowance runs out, that marginal rate is far higher than any headline band, because the allowance is withdrawn at the same time as tax is charged.
Income Tax rates for England, Wales and Northern Ireland
Applied to taxable income, meaning what is left after the £12,570 Personal Allowance. On the full standard allowance, higher-rate tax starts at £50,270 of gross pay.
Income Tax rates for Scotland
Scottish taxpayers pay Scottish rates on earnings. National Insurance and Student Loan rules are the same across the UK.
Employee National Insurance (category A)
Class 1 National Insurance is charged on each pay period rather than on the year as a whole, so an uneven year can produce a different total from an even one.
Student Loan and Postgraduate Loan repayments
Repayments are a percentage of income above the plan threshold, not of your whole salary, and are rounded down to whole pounds each pay period.
Take-home pay on common salaries in 2026/27
Worked out on the simplest arrangement: England, Wales or Northern Ireland, National Insurance category A, paid monthly, with no pension contribution and no Student Loan. Add any of those in the calculator above and the figures change — usually by more than people expect.
Common questions
How much is £30,000 a year after tax?
On the basis in the table above, £30,000 leaves £2,093.34 a month, or £25,120.08 a year, with 16.3% going in Income Tax and National Insurance. Your own figure will differ: where you pay tax, what you put into a pension and how, whether you are repaying a Student Loan, and your National Insurance category all change it. That is why the calculator above shows every deduction separately instead of one number.
What is the difference between salary sacrifice, net pay and relief at source?
They are three ways of paying the same money into the same pension, and they do not cost the same. Under salary sacrifice your gross pay is reduced before both Income Tax and National Insurance, so you save both. Under a net pay arrangement the contribution comes out before tax but after National Insurance, so you save tax only. Under relief at source it comes out of your take-home pay and your provider adds basic-rate relief, with any higher-rate relief usually claimed back from HMRC yourself. The calculator prices all three side by side on your own figures.
Why does earning more sometimes leave me barely better off?
Because several rules bite at once. Above £100,000 the Personal Allowance is withdrawn by £1 for every £2 of income, which stacks on top of higher-rate tax. Child Benefit is clawed back through the High Income Child Benefit Charge. Some childcare support stops entirely at a threshold rather than tapering. The calculator measures your marginal rate by running the whole calculation again with one more pound of pay, so the figure it shows is the real one for your circumstances, not a quoted band.
Is take-home pay different in Scotland?
Yes, for Income Tax. Scotland sets its own bands and rates on earned income, shown in the table above. National Insurance, Student Loan repayments and the Personal Allowance are set UK-wide, so two people on the same salary either side of the border differ only by the Income Tax slice.
Does this calculator store my salary?
No. Every figure is calculated on request and nothing is written to a database or a log. Sharing a link puts your inputs in the URL you copy, so share it only with people you are happy to show it to.
Where do the rates come from?
Every rate on this page and in the statement above is taken from HMRC's published tables for the tax year you select, and each source is linked in the statement. The pension Annual Allowance modelled is £60,000 and the National Living Wage used for the minimum-wage check is £12.71 an hour. Figures are estimates for the arrangement you describe and are not personal financial advice.
