Pension insight
Increasing pension from 5.0% to 8.0% would reduce monthly take-home by around £84, while increasing retirement contributions.
How salary tax works in the UK
UK take-home pay starts with your gross salary, then deducts Income Tax, National Insurance, and
any pension and student loan repayments. The exact amount depends on your salary level, tax code,
and deduction settings.
Because each deduction uses its own thresholds and rates, the gap between gross and net pay is not
a single percentage — it shifts as your salary crosses different bands. That is why a calculator is
more useful than a rule of thumb.
Income Tax bands explained
For England, Wales, and Northern Ireland, Income Tax is applied in bands. The standard Personal
Allowance is £12,570, meaning you pay no Income Tax on the first £12,570 of earnings. Above that,
the basic rate of 20% applies up to £50,270, the higher rate of 40% applies from £50,271 to
£125,140, and the additional rate of 45% applies above £125,140.
The Personal Allowance reduces by £1 for every £2 of income above £100,000. This creates an
effective 60% marginal rate between £100,000 and £125,140, which is why take-home pay can drop
sharply in that range.
National Insurance explained
Employee Class 1 National Insurance uses a separate threshold and rate structure. You pay nothing
on earnings up to the Primary Threshold (£12,570 for 2025/26), then 8% on earnings between the
Primary Threshold and the Upper Earnings Limit (£50,270), and 2% on anything above.
NI is calculated on each pay period independently, unlike Income Tax which is cumulative across
the year. This calculator annualises your gross pay to estimate the total.
How pension contributions affect take-home pay
Workplace pension contributions reduce your taxable pay if made under a salary sacrifice or
net-pay arrangement, which can lower both Income Tax and National Insurance. The minimum employer
auto-enrolment contribution is 3%, with a typical combined minimum of 8%.
Increasing your pension contribution trades take-home pay for retirement savings. A 1% increase on
a £35,000 salary reduces monthly net pay by roughly £23 (after basic-rate tax relief) while adding
£350 per year to your pension pot.
Student loan repayments explained
Student loan deductions are based on earnings above a plan-specific threshold, not on your total
salary. Plan 1 deducts 9% above £24,990, Plan 2 deducts 9% above £27,295, Plan 4 deducts 9%
above £31,395, and Plan 5 deducts 9% above £25,000 (2025/26 thresholds). Postgraduate loans
deduct 6% above £21,000.
If you have both an undergraduate and postgraduate loan, both deductions apply at the same time,
which increases the total amount deducted from each payslip.
What this calculator assumes
Results are based on UK tax-year rates for England, Wales, and Northern Ireland. Scottish income
tax rates are not currently supported. The calculator uses a standard cumulative tax code and
assumes your employment runs for the full tax year.
It does not include employer NI, benefits in kind, overtime, bonuses, or dividend income. Pension
contributions are modelled as salary sacrifice. If your employer uses a different pension
arrangement, the tax relief effect may differ slightly.
Frequently Asked Questions
It provides a solid estimate using current UK tax-year assumptions for Income Tax, employee
National Insurance, student loan thresholds, and your selected pension settings. Actual payroll
outcomes can vary by employer setup and specific tax circumstances.
Yes. If pension is enabled, your chosen percentage is included in deductions and reflected in
your take-home pay estimate.
The default is 1257L. You can change it in Advanced options to test other tax code scenarios.
Yes. If your earnings are above your plan threshold, repayments are deducted from pay and lower
your net income.
Gross salary is your pay before deductions. Net salary (take-home pay) is what remains after
tax and other deductions are removed.
