One transparent route from salary to gross pay plus employer NI
The engine applies the selected annual UK Income Tax bands and monthly category A National Insurance thresholds to regular annualised pay. The monthly take-home figure is an average, not a PAYE payslip. Inverse modes use the same forward engine.
Net to gross
Start with target take-home pay and solve for the minimum supported gross salary.
Gross plus employer NI
Start with a budget covering gross pay plus employer NI and solve for supported gross and take-home pay.
Questions and calculation boundaries
- Does this replace payroll software?
- No. Income Tax is an annual liability estimate, monthly take-home is an average, and the tool does not calculate PAYE withholding, produce payslips, file PAYE, or process payroll.
- Why is annual gross pay limited to £100,000?
- Above £100,000, the Personal Allowance tapers and the bounded annual estimate would need additional inputs and rules.
- What is included in the employer figure?
- Gross pay plus employer National Insurance only. Employer pension contributions, Apprenticeship Levy, Employment Allowance, and other employment costs are excluded.

Rates are held in an effective-dated manifest. The annual Income Tax estimate and monthly National Insurance calculation are labelled separately, and unsupported employment profiles stop at a visible boundary.
