Salary after tax calculator

Inputs that can change the result

Use this page to compare common UK salaries after Income Tax, National Insurance, pension contributions, and student loan deductions. Open a salary example, then adjust the real deduction assumptions in the calculator. Salary estimates can change when the tax year, UK region, tax code, pension method, student loan plan, pay frequency, bonus, overtime or salary-sacrifice assumptions change.

• Compare annual, monthly, weekly and daily take-home pay before changing assumptions.
• Review Income Tax, National Insurance, pension and student-loan rows before comparing take-home pay.
• Use examples as planning starting points, not as payslip or payroll decisions.

How to use the salary output

The useful figure for budgeting is usually take-home pay after Income Tax, National Insurance, pension deductions and student loan deductions. Gross pay helps compare jobs, while net pay is usually the better starting point for bills, savings and borrowing checks.

Checks before comparing with a payslip

Real payslips can differ because payroll works by pay period and can include tax-code changes, pension method differences, student-loan starts or stops, taxable benefits, salary sacrifice, bonuses, overtime, arrears, refunds, or rounding. Match the calculator settings to the payslip before treating a difference as meaningful.

What to review when comparing jobs

Two jobs with the same headline salary can feel different once pension contribution rate, employer pension method, student-loan plan, bonus pattern, overtime, tax code, region, salary sacrifice and pay frequency are considered. Compare the monthly net figure with commuting costs, bills and savings goals before deciding whether a higher gross salary improves the household plan.

How to turn the page into a real estimate

Start by matching the pay basis: annual salary, hourly rate, weekly hours, pay frequency and whether the figure is full-year or part-year. Then match the deductions that usually move the result the most: pension method, pension rate, student-loan plan, postgraduate loan, tax code, Scottish or Welsh tax treatment, bonus, overtime, taxable benefits and salary sacrifice. If the page is a comparison page, keep both sides on the same tax year and pension method before reading the difference. If it is a required-salary or pro-rata page, treat the answer as a target estimate and rerun it with a cautious lower-income or higher-deduction scenario before using it for bills, rent, borrowing or savings.

Make the estimate your own

Use the visible result as a starting point, then change the assumptions that apply to your situation. For salary pages, that usually means tax year, region, tax code, pension method, student loan plan, bonus, overtime and salary-sacrifice settings. For borrowing, debt or budget pages, it means the real payment amount, term, interest rate, balance, bill timing, savings target and any expected income change. Keep the result separate from advice or approval decisions: PayBreakdown helps you model the numbers, while official sources, employer records, provider documents and professional support are still the right place for final checks. If a change is close to a threshold, rerun the calculation with a cautious higher-cost or lower-income scenario before relying on the result.
