1. What is Salary Exchange?

Salary exchange (or salary sacrifice) is an arrangement where employees give up part of their salary in exchange for non-cash benefits. This can reduce income tax and National Insurance contributions for both employee and employer.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Gross\ Pay \) — Total annual salary before deductions
• \( Income\ Tax \) — Amount deducted for income tax
• \( National\ Insurance \) — Amount deducted for National Insurance
• \( Salary\ Sacrifice \) — Amount sacrificed for benefits

Explanation: The calculation shows your take-home pay after all mandatory deductions and voluntary salary sacrifice arrangements.

3. Importance of Net Pay Calculation

Details: Understanding your net pay helps with budgeting and financial planning. Salary exchange can be tax-efficient but reduces your taxable income, which may affect pension contributions and other benefits.

4. Using the Calculator

Tips: Enter all amounts in GBP. Values must be positive numbers. For accurate results, use your actual tax and NI figures from your payslip or tax code notice.
