UK employer cost calculator
What a UK employee really costs: gross salary plus employer National Insurance (secondary Class 1 contributions). Employer National Insurance is UK-wide — one rate above one threshold, identical in England, Wales, Northern Ireland and Scotland — so this matrix's jurisdictions differ in label, not in figures. The liability shown is gross: the Employment Allowance is not deducted (see Known limits).

| Line | Per year |
|---|---|
Gross salaryWhy this line?Gross pay for the pay period, before any deduction. Why this rate: Set by the employment contract; Income Tax and National Insurance are both computed from it (on different bases: tax is annual/cumulative, NICs are per period). What changes it: Hours worked, salary level, bonuses, overtime and taxable benefits. Source: Employment contract — verified . | £60,000.00 |
Employer National Insurance (category A)Why this line?Employer (secondary) Class 1 National Insurance, category A: 15% of earnings above the Secondary Threshold (£96/week, £417/month, £5,000/year). The rate rose from 13.8% in April 2025 when the threshold fell from £9,100 to £5,000; both are unchanged for 2026/27. The Employment Allowance (up to £10,500 a year for eligible employers) is NOT deducted in v1. Why this rate: HMRC — Rates and thresholds for employers 2026 to 2027 (employer rates, category A: 15% in every band above the Secondary Threshold). What changes it: Earnings above the Secondary Threshold; employer eligibility for the Employment Allowance (not modeled); special category letters for under-21s, apprentices, veterans, Freeport and Investment Zone employees (not modeled). Source: HMRC — Rates and thresholds for employers 2026 to 2027 (Employer (secondary) contribution rates, category letter A: 15% in every band above the Secondary Threshold) — verified 2026-10-28. | £8,249.40 |
Total employer costWhy this line?Total employer cost: gross salary plus employer National Insurance. Pension auto-enrolment contributions, the Apprenticeship Levy and benefits in kind are not included in v1, so this is a floor, not the full cost of employment. Why this rate: Sum of the rounded lines (structured result contract — screen, PDF and tests can never diverge). What changes it: Salary level and any employer pension provision (not modeled). Source: Structured result — sum of the lines above — verified . | £68,249.40 |

Methodology, limits and sources
Rates verified on 2026-10-28 (primary sources listed per line).
UK engine, employer side: secondary Class 1 National Insurance, category A, at 15% on pay above the Secondary Threshold (£417 a month), computed per employee per month and scaled by headcount — identical employees, so the totals are exact multiples. The Employment Allowance is NOT netted against the result (see Known limits).
Data status
Employer National Insurance parameters (2026/27): primary-verified against HMRC's published employer rates and thresholds (28 October 2026). The engine reproduces HMRC's published CWG2 worked examples of employer National Insurance to the penny.
Known limits
- Employment Allowance is NOT deducted. The employer National Insurance shown is the gross liability; an eligible employer can claim up to £10,500 a year against that liability and would pay less — eligibility is HMRC's call.
- Category A only: the under-21 and apprentice reliefs run through other category letters (their own upper secondary thresholds) and are not modelled.
- Pension auto-enrolment contributions, the Apprenticeship Levy and statutory payments are not modelled: the totals here are salary plus employer National Insurance only.
