UK payroll and employer cost calculator 2026/27

Calculation direction

Estimated result

Enter the supported annual amount and calculate to see the tax, National Insurance, take-home pay, and employer cost breakdown.

One transparent route from salary to employment cost

The engine applies the selected UK income-tax bands, employee National Insurance, and employer National Insurance to regular annualised pay. Inverse modes use the same forward engine rather than a separate approximation.

Gross to net

Start with contractual annual gross salary and see deductions, take-home pay, and employer cost.

Net to gross

Start with target take-home pay and solve for the minimum supported gross salary.

Employer budget

Start with total employer budget and solve for supported gross and take-home pay.

Questions and calculation boundaries

Does this replace payroll software?
No. It is a planning calculator for the declared standard case and does not file PAYE or process payroll.
Why is annual gross pay limited to £100,000?
The published scope assumes tax code 1257L. Higher-income personal-allowance and coding adjustments need a broader payroll model.
Is Employment Allowance deducted?
No. Employment Allowance depends on employer circumstances and is not subtracted from the result.

Rates are held in an effective-dated manifest. Unsupported employment profiles stop with a visible boundary instead of silently using the standard case. Confirm the result with payroll software or a payroll professional before running payroll.
