The full guide

Everything worth knowing about salary

Worked examples with real figures, the order payroll applies them in, and the traps that catch people out.

01

Gross on the contract, net in the account

On £35,000 with the usual pension the gap between the salary you agreed and the money that lands runs to about £900 a month. Nobody hands you a breakdown of where it went.

Type your salary above and the breakdown appears in the order payroll builds it. Check it against a payslip you already have. If net pay agrees within a pound, every scenario you run after that is worth trusting.

Match a real payslip first

Copy the tax code, pension percentage and student loan plan from the slip. A calculator that agrees with last month is a calculator you can plan next year with.

02

The order payroll works in

Deductions are not a flat set that each take a bite of the same cake. They run in sequence, and the sequence decides the cost of every one after the first.

Pension goes first under salary sacrifice, leaving gross pay before tax and National Insurance ever see it. Under relief at source it leaves net pay instead and HMRC tops the pot up. Same percentage on paper, different payslip.

Income tax then applies band by band against the tax code. National Insurance follows, worked out per pay period rather than across the year. Student loan sits on top of all of it and never reduces taxable pay.

Change the order and the answer changes. That is why a payslip with the same gross as a colleague's can pay a different net.

£35,000, line by line

Take £35,000, a standard tax code and five percent into an auto enrolment pension. The pension takes £1,750 first, so income tax looks at £33,250.

The allowance covers £12,570 at nothing. The rest falls in the basic rate band, giving income tax near £4,136. National Insurance charges eight percent above the primary threshold, close to £1,794.

Take home lands around £27,320 a year, roughly £2,277 a month.

04

Income tax, band by band

Only the money inside a band pays that band's rate. Crossing into higher rate reprices the slice above the threshold and nothing beneath it.

Between £100,000 and £125,140 the personal allowance falls away by a pound for every two pounds earned. The headline says forty percent. The real rate across that stretch is sixty, which is why a bonus there can leave £400 of every £1,000.

Thresholds move rarely while pay drifts upward, so more of each salary lands in a higher band every year without any rate changing at all.

National Insurance behaves differently to tax

The rate steps down above the upper earnings limit rather than up, so a higher earner pays less NI on an extra pound than a basic rate earner does.

It is also calculated per pay period. A £6,000 bonus paid in March costs less NI than £500 a month across the year, because the March slice is pushed past the limit in one go while the monthly version never reaches it.

Self employed contributions follow a parallel shape on trading profits rather than salary, with their own thresholds and a lower headline rate.

06

The pension percentage is the strongest lever you have

A pound in the pot costs a basic rate taxpayer eighty pence of take home and a higher rate taxpayer sixty. Inside the allowance taper it can cost forty. The band you sit in sets the price.

Salary sacrifice removes the contribution from gross pay, so it avoids National Insurance as well as income tax. Relief at source takes it from net pay and HMRC adds the basic rate back, leaving higher rate taxpayers to claim the rest through self assessment.

Employer matching outweighs a small salary difference within a couple of years, and the gap keeps widening for the rest of a working life.

Why a pay rise lands smaller than it reads

New pay stacks on top of old pay, so it is charged at the rate of the band it lands in rather than your average rate. A £3,000 rise that crosses the higher rate threshold can hand over roughly £1,240 of itself.

Run the current salary, note the net. Run the new one, note the net. The difference between those two figures is the only number worth celebrating.

Then route part of the rise into the pension. Take home barely moves, the pot jumps and the tax bill falls. On the wrong side of a threshold that trade is close to free money.

08

Four things that quietly move your net pay

A tax code change mid year. HMRC adjusts the code, payroll applies it, and the letter explaining it rarely gets read. Check the code on the payslip against the one you expect.

A taxable benefit such as private medical cover. It shrinks the allowance, so a perk raises the tax bill and take home falls in the month it starts.

A switch to salary sacrifice. Gross drops before anything else, which changes every line beneath it and can affect mortgage affordability too.

A bonus month. Income tax evens out across the year through the cumulative system. National Insurance never does.

09

One payslip is a snapshot, five years is the film

Sixty payslips turn small monthly differences into serious money. A £40 monthly gap is £2,400 across five years before anything grows.

Pension shows it hardest. Two extra percent on £45,000, matched by an employer and topped by relief, adds close to £2,000 a year to the pot. Compound that for thirty years at a modest rate and it clears six figures.

Multiply the monthly gap by sixty for the cash answer, then apply growth to the yearly pension gap for the long one.

Where the numbers come from

Rates, bands and thresholds follow published HMRC and gov.uk figures for the 2025/26 tax year, held in one table that every tool reads. April arrives, the table changes, and the results move together.

Earlier years stay available through the year selector, so a late self assessment runs on the numbers that applied at the time rather than today's.

Some cases still need an accountant. K codes carrying negative allowances, bespoke sacrifice arrangements, the annual allowance taper for very high earners, and anything involving two employments at once.

11

Where to go next

UK Salary Calculator answers one question. The salary calculator turns gross into net, the income tax calculator splits the bill by band, the National Insurance calculator shows the step at the upper limit, and the pension calculator prices a percentage change three ways at once.

Every tool reads the same rate table, so two pages never disagree. Run this one, note the figure, then open the next and watch which line moves.

12

What the number will not tell you

Cash is the floor of a decision, not the decision. An hour a day handed back by a shorter commute is roughly two hundred and fifty hours a year, and nothing prices that against a manager worth working for.

Some benefits convert cleanly. Health cover has a taxable value, a learning budget has a receipt, extra leave has a daily rate. Share options that vest over four years and enhanced parental leave do not, so weigh those separately rather than treating them as salary.
