1. What is UK Employer Cost Calculation?

The UK Employer Cost calculation determines the total cost to an employer for employing staff, including salary, employer National Insurance contributions at 15% for 2025/26 tax year, and any additional employment costs.

2. How Does the Calculator Work?

The calculator uses the UK employer cost formula:

Where:

• \( Salary \) — Employee's gross annual salary in GBP
• \( Employer NI \) — Employer National Insurance contribution at 15% of salary
• \( Other Costs \) — Additional employment costs (pension contributions, benefits, etc.)

Explanation: This calculation helps employers understand the true cost of employment beyond just the employee's salary, including mandatory National Insurance contributions and other employment-related expenses.
