Estimate take-home pay when a full-time salary is adjusted for part-time hours, a pro-rata contract, or a temporary drop in pay.
Compare a full-time salary with a reduced-hours or reduced-pay version. This is useful when checking part-time offers, returning to work, or modelling temporary pay changes.
On £35,000 a year with a standard 2026/27 tax code, no pension, no student loan, the figures work out like this. Open a calculator to put your own numbers in.
| Tax/source year | 2026/27 |
|---|---|
| Region | England/Wales/Northern Ireland |
| Tax code basis | 1257L where the page uses PAYE defaults |
| Pension basis | No pension deduction unless this example says otherwise |
| Student loan basis | No student loan unless selected in this example |
| Gross pay | Employment pay before PAYE deductions and pension or loan settings. |
|---|---|
| Income Tax | Tax estimated from the selected tax-year, region, tax code and taxable-pay assumptions. |
| National Insurance | Employee NI is calculated separately from Income Tax and may not follow the same bands. |
| Pension and loans | Pension method and student-loan plan can change take-home pay and payslip comparisons. |
| Pension contribution | Changing the rate or method can change taxable income, National Insurance and take-home pay. |
|---|---|
| Tax code and region | Scottish Income Tax, Welsh codes, emergency tax or a non-standard tax code can move the result. |
| Student loan plan | A different plan can change deductions because each plan uses its own threshold and repayment rate. |
| Bonus, overtime or second job | Extra pay and payroll timing can make a real payslip differ from the smooth annual estimate. |
| Tax code | HMRC tax-code changes, K codes, BR/D codes, or emergency markers can change PAYE deductions. |
|---|---|
| Cumulative basis | Week 1, Month 1 or non-cumulative payroll can differ from a smooth annual calculator estimate. |
| Pension method | Relief at source, net pay and salary sacrifice can affect taxable pay and take-home pay differently. |
| Payroll timing | Bonus, overtime, arrears, refunds, cut-off dates and corrections can all move a single payslip. |
| Why is the tax on my payslip higher than expected? | payslip difference |
|---|---|
| What do the main payslip lines mean? | payslip explainer |
| What tax code should I use for modelling? | tax code |
| How much does pension reduce take-home pay? | pension comparison |
| How does this affect a monthly budget? | budget planning |
| What is not decided here | PayBreakdown does not decide payroll correctness, lender approval, benefit entitlement or employer compliance, and does not give regulated financial, mortgage, debt, tax, payroll or legal advice. |

The figures on this page are worked from pro-rata pay, using the values below. Open the calculator if your example salary differs.
This estimate is worked out on £35,000 annual gross. Change any of those and the take-home figure moves; pension method and student loan plan usually move it most. A payslip can differ from any calculator because payroll works pay period by pay period, so a tax-code change, a bonus, arrears or a refund can land in one month and not the next. See how each deduction is worked out.
No. The tool is a reduced-pay and pro-rata planning model. It can model furlough-style pay reductions, but it is not a current government support checker.
The full-time salary, full-time hours, actual hours, and selected tax, pension, and student loan assumptions all affect the estimated take-home pay.
