Gross vs Net Pay

Your advertised salary is not usually the amount you receive.

Gross salary is your pay before deductions. Take-home or net pay is the amount left after deductions such as Income Tax and employee National Insurance.

Your actual payslip may also include pension contributions, student loan repayments, salary sacrifice and other payroll adjustments.

Why Calculate Salary?

A take-home estimate can make salary comparisons clearer.

Comparing salaries based only on gross annual pay can hide differences in deductions and pension arrangements.

A take-home estimate can help when assessing a new job, reviewing a pay rise, setting a household budget or comparing different employment offers.

Salary Breakdown

What can reduce your gross salary?

Your payslip can contain several deductions. Understanding the main categories makes it easier to interpret your take-home pay.

TAX

Income Tax

Income Tax is generally deducted through PAYE for employees. The amount depends on taxable income, allowances and your tax code.

NI

National Insurance

Employee National Insurance contributions are calculated using the applicable earnings thresholds and rates.

PEN

Pension Contributions

Workplace pension contributions can reduce the amount available as take-home pay, depending on how the scheme operates.

Make Better Salary Comparisons

Look beyond the headline salary.

A higher gross salary does not automatically mean the same percentage increase in take-home pay. Tax bands and other deductions can affect the final difference.

01 Compare both gross salary and estimated net pay when considering a new role.
02 Check pension contributions and whether your employer offers salary sacrifice arrangements.
03 Consider benefits, bonuses and other compensation rather than looking only at base salary.
04 Use your actual tax code and payroll information for a more precise personal estimate.
