1. What is the NI and Pension Calculator?

The NI and Pension Calculator calculates National Insurance contributions and pension contributions based on salary and respective rates. It provides a quick estimation of deductions for UK employees.

The calculator uses simple percentage-based calculations:

Where:

• \( Salary \) — Gross salary amount in GBP
• \( NI\ Rate \) — National Insurance rate as decimal
• \( Pension\ Rate \) — Pension contribution rate as decimal

Explanation: The calculations are straightforward percentage deductions from the gross salary amount.
