1. What is Employer Cost Calculation?

The Employer Cost Calculation estimates the total cost to an employer for an employee's salary in the UK, including National Insurance contributions and pension contributions. This provides a comprehensive view of the true cost of employment beyond just the employee's gross salary.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Salary \) — Employee's gross annual salary in GBP
• \( NI \) — Employer National Insurance at 13.8% on earnings above £12,570
