Open calculator →Why EmployerCosts
The salary is only part of what a hire costs. On top of gross pay, a UK employer pays secondary National Insurance, pension contributions, the Apprenticeship Levy for larger payrolls, and statutory pay for holiday, sickness, maternity and notice. These on-costs are easy to underestimate and hard to keep current as rates change.
