How the reverse estimate works
The calculator tests annual gross salary against a forward Income Tax and National Insurance calculation, including tax bands and allowance taper. It returns a gross amount to the nearest penny that reproduces your annual net target within a penny. Actual PAYE withholding and NI are worked out by pay period, so individual payslips may differ.
