Salary cost

Salary calculator for employers (UK, 2026/27)

When an employer sees a salary figure, the actual cost is higher — employer NI at 15% above £5,000, pension at 3% of qualifying earnings, and any workspace or equipment overheads on top. This salary calculator for employers converts a gross salary into a full annual and monthly employer cost for 2026/27, so offer approvals, headcount budgets and cost-per-hire estimates use a consistent number.

UK scope: England, Scotland, Wales and Northern Ireland employer payroll planning for the 2026/27 tax year.
