About the UK Salary Sacrifice Calculator
Use this salary sacrifice calculator to estimate how pension contributions can reduce your taxable pay, Income Tax, National Insurance, and take-home pay for the 2026/27 tax year.
Salary sacrifice is commonly used for workplace pension contributions. It can be tax efficient because your salary is reduced before Income Tax and employee National Insurance are calculated.
This means part of your pension contribution may be effectively funded by tax and NI savings.
This calculator is designed for UK employees who want a simple estimate of their tax saving from salary sacrifice pension contributions.
