UK Employer PAYE & Employment Cost Calculator (2026/27).
Calculate the true cost of employing someone in the UK for 2026/27, including employer National Insurance at 15%, auto-enrolment pension and the £10,500 Employment Allowance.
For 2026/27, employers pay Class 1 secondary National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, on top of gross salary. Most employers can offset up to £10,500 of this through the Employment Allowance. You must also pay at least the minimum auto-enrolment workplace pension contribution. This calculator adds these to gross pay to show the true cost of employing someone.
