How to Calculate Take-Home Pay: A Step-by-Step Guide for 2026

Gross pay is your salary before anything is taken off. That part is easy. What trips people up is what counts as gross pay in the first place. A guaranteed annual bonus, a shift allowance, a car allowance paid in cash and most overtime are all part of gross pay for tax purposes, even though people mentally file them separately from 'my salary'.

If you are paid hourly rather than annually, convert first: multiply your hourly rate by your contracted weekly hours, then multiply by 52. A £22 hourly rate at 37.5 hours a week is £42,900 a year, and every calculation from here on uses that annual figure. Do the conversion before you start deducting anything, because every threshold in every tax system in this guide is set annually.

This is the step almost everyone forgets, and it is the one that moves the number most. Some deductions are taken from your gross pay before income tax is calculated at all, which means they reduce your tax bill as a side effect. In the United States that is a traditional 401(k) contribution, health insurance premiums taken through a cafeteria plan, and HSA or FSA contributions. In the UK it is a salary-sacrifice pension. In India it is the portion of your CTC that goes into EPF. In Canada it is an RRSP contribution made through payroll.

The practical effect is that £100 into a salary-sacrifice pension does not cost you £100 of take-home pay — it costs you about £72 if you are a basic-rate taxpayer, because the tax and National Insurance you would have paid on that £100 never arises. Two colleagues on exactly the same salary can have net pay figures hundreds a month apart purely because one of them contributes more here.

What remains after step two is roughly your taxable income — but only after you remove the slice that is not taxed at all. The UK calls this the personal allowance (£12,570). The US calls it the standard deduction. Canada calls it the basic personal amount. India's new regime gives you a standard deduction plus a rebate that wipes out tax entirely at lower incomes. Australia simply has a 0% band up to $18,200. Different names, identical job.

Then, and only then, do you apply the rates — and you apply them slice by slice, not all at once. This is the single most misunderstood part of the whole exercise. If your income puts you in the 40% band, you do not pay 40% of your salary. You pay 40% only on the pounds that sit above the point where that band begins. Everything below it is still taxed at the lower rates, exactly as it was before your pay rise.

Take a £60,000 UK salary. The first £12,570 is untaxed. The next £37,700 is taxed at 20%, which is £7,540. The remaining £9,730 is taxed at 40%, which is £3,892. Total income tax: £11,432 — about 19% of gross, not 40%. That gap between your top band and your actual percentage is your effective tax rate, and it is the number that actually matters when you are comparing offers.

Here is where a naive bracket-table calculation goes wrong. Sitting alongside income tax is a second set of deductions with completely different thresholds and, crucially, completely different behaviour. In the US it is FICA: 6.2% for Social Security up to an annual wage base, plus 1.45% for Medicare with no cap at all. In the UK it is Class 1 National Insurance at 8%, dropping to 2% above the upper earnings limit. In Canada it is CPP and EI, both of which stop once you hit an annual maximum. In Australia it is the 2% Medicare levy on your whole taxable income.

Notice the two different shapes. Capped contributions like Social Security, CPP and EI take a shrinking percentage of your pay as your salary rises, because they stop entirely at a ceiling. Uncapped ones like Medicare and the Medicare levy keep taking the same slice forever. This is why high earners often find their effective total deduction rate rises more slowly than they feared past a certain point — one whole layer of deductions has simply switched off.

It is also why 'what tax bracket am I in?' is such an incomplete question. A US employee earning $80,000 might be in the 22% federal bracket while paying an effective federal rate closer to 12%, plus 7.65% FICA on almost everything, plus whatever their state charges. Three separate systems, three separate answers, one paycheck.

The last layer is the one that never appears in any bracket table because it is not tax at all. UK graduates repay 9% of everything above their student loan threshold. Australians repay HECS-HELP on a sliding scale. Americans may have court-ordered garnishments, Roth 401(k) contributions or union dues. Many people worldwide have private health cover, life insurance or a workplace savings scheme taken directly from net pay.

These deductions come out of what is left, so they do not reduce your tax — but they absolutely reduce the money that reaches your bank account. If your payslip does not match your calculator estimate, this is the first place to look, followed by whether your tax code or withholding allowances are correct. A wrong tax code is the second most common cause of a surprise, and it is worth checking every year rather than assuming payroll has it right.

Say you are offered $95,000 in California. Gross pay is $95,000. You put 6% into a traditional 401(k), so $5,700 comes off before tax, leaving $89,300. Subtract the standard deduction and federal tax is charged on roughly $74,700 — worked through the 10%, 12% and 22% brackets rather than at a flat 22%. Add California state tax on its own bracket table with its own standard deduction, then add FICA at 7.65% charged on the full $89,300 because pre-tax retirement contributions still attract payroll tax in the US.

The result is a net figure in the region of $67,000 to $70,000 a year, depending on filing status and benefits — roughly $5,600 to $5,800 a month, not the $7,900 that dividing $95,000 by twelve suggests. That gap of over $2,000 a month is exactly why doing this properly before you accept an offer or sign a lease is worth ten minutes.

The same sequence works everywhere. Only the names, the thresholds and the number of layers change. Run it on the calculator on this site, then compare it against your actual payslip once you start — if the two disagree by more than a small margin, one of the after-tax deductions in step five or an incorrect tax code is almost always the reason.

Three errors account for most bad estimates. The first is applying your top tax rate to your whole salary, which massively overstates your tax. The second is ignoring payroll contributions entirely, which understates it. The third is comparing a gross salary in one country against a net salary in another, which produces a completely meaningless answer — and it happens constantly in job-offer conversations across borders.

There is also the timing trap. Bonuses are frequently taxed at a higher withholding rate in the month they are paid, which makes that single payslip look alarming even though the annual figure works out correctly. And if you start a job mid-year, your first few payslips may deduct too much or too little until your cumulative position settles down.
