Where it goes
How the salary calculator works
This calculator turns a gross salary into take-home pay by subtracting pension contributions, income tax, payroll/social tax, and (for the UK) any student loan repayments. The currency switch in the top bar toggles between UK 2024/25 rules and US 2024 federal rules — the maths is fully band-aware in both cases.
UK rules (England & Wales, 2024/25)
- Personal allowance: £12,570 tax-free (tapers above £100k, vanishes at £125,140)
- Basic rate: 20% on income from £12,571 to £50,270
- Higher rate: 40% from £50,271 to £125,140
- Additional rate: 45% above £125,140
- Class 1 NI: 8% between £12,570 and £50,270, then 2% above
US rules (single filer, 2024 federal)
- Standard deduction: $14,600 (subtracted before brackets)
- Federal brackets: 10% / 12% / 22% / 24% / 32% / 35% / 37%
- Social Security: 6.2% on wages up to $168,600
- Medicare: 1.45% on all wages, plus 0.9% above $200,000
- State tax: not modelled — varies from 0% (TX, FL, WA) to 13%+ (CA)
Worked example — UK
Scenario: £55,000 gross salary, 5% salary-sacrifice pension, no student loan.
Pension: £55,000 × 5% = £2,750 → taxable pay £52,250
Income tax: 0% on first £12,570 + 20% on £37,700 (£7,540) + 40% on £1,980 (£792) = £8,332
NI: 8% on £37,700 (£3,016) + 2% on £1,980 (£40) = £3,056
Take-home: £55,000 − £2,750 − £8,332 − £3,056 = £40,862 / year (≈£3,405/mo)
Frequently asked questions
How is UK take-home pay calculated?
Take-home pay is your gross salary minus pension contributions, Income Tax, National Insurance, and any student loan deductions. For 2024/25 in England and Wales you get a £12,570 personal allowance, then 20% basic rate up to £50,270, 40% higher rate up to £125,140, and 45% above. Class 1 employee NI is 8% between £12,570 and £50,270, and 2% above that.
How is US take-home pay calculated?
For a 2024 single filer you subtract the $14,600 standard deduction, then apply federal brackets of 10/12/22/24/32/35/37%. FICA is added on top: Social Security at 6.2% (capped at $168,600 of wages) and Medicare at 1.45% on all wages, plus an extra 0.9% on wages above $200,000. State and local income taxes are not included — see our note below.
What is the personal allowance and does it taper?
The standard UK personal allowance is £12,570 — income up to that level is tax-free. For incomes above £100,000 the allowance tapers down by £1 for every £2 of extra income, vanishing entirely at £125,140. This creates a punitive 60% effective marginal rate inside that band, which is why high earners often boost pension contributions to keep taxable pay below £100k.
Does pension salary sacrifice reduce my tax?
Yes. Salary-sacrifice pension contributions are deducted from gross pay before Income Tax and National Insurance are applied, so they reduce your taxable income, your tax bill, and your NI. This calculator treats the pension percentage as salary sacrifice — net relief, no separate tax-relief top-up needed.
How are student loan repayments calculated?
UK Plan 1, 2, 4 and 5 borrowers repay 9% of income above their respective thresholds (£24,990 / £27,295 / £31,395 / £25,000). Postgraduate loan repayments are 6% above £21,000. Repayments are taken via PAYE alongside tax and NI, and any unpaid balance is written off after the plan-specific term (typically 30–40 years).
Why is my US figure missing state tax?
State and local income taxes vary enormously — from 0% in states like Texas, Florida and Washington to over 13% in California — and depend on filing status, deductions and credits unique to each state. Including them generically would mislead more than help, so we model federal + FICA only.
