Frequently asked questions

How much does a £30,000 employee cost?

About £33,750 a year before pension: £30,000 salary plus £3,750 employer National Insurance (15 % of £25,000). With 3 % pension on the whole salary, as the calculator applies it, about £34,650; on qualifying earnings only it would be £34,470.

Is holiday pay an extra cost?

For salaried staff it is inside the gross salary. For hourly workers budget 12.07 % on top of worked hours, which is the statutory 5.6 weeks of leave.

Does the Employment Allowance apply to me?

Most employers can, since the £100,000 limit on the previous year's employer NI was removed in April 2025; the main exclusion is a company whose only employee paid above the threshold is also a director. It reduces the yearly employer NI by up to £10,500. The calculator shows the cost before the allowance.
