Important payroll cost guidance
This calculator uses standard 2026/27 assumptions for employer National Insurance and basic automatic enrolment pension modelling. Actual payroll costs can vary depending on employee age, employment status, pension scheme, salary sacrifice, benefits, Employment Allowance eligibility and other payroll rules.
Salary is not the full cost
Employers may need to budget for gross salary, employer National Insurance, employer pension contributions, payroll software, benefits, equipment, training, insurance and other staff-related costs.
Employment Allowance needs care
Employment Allowance can reduce eligible employer National Insurance liabilities, but not every employer qualifies. Treat the allowance toggle as a planning estimate, not confirmation of eligibility.
