What's the Difference Between Gross and Net Pay?

Gross pay is the headline figure before anything is taken off. Net pay — your take-home — is what's left after income tax, National Insurance, pension and any student loan come out. Understanding the gap helps you avoid nasty surprises on payday.

Key Facts

Gross pay is your salary before deductions
Net pay is what reaches your bank after tax and other deductions
Common deductions are income tax, NI, pension and student loan

Reading your payslip

Your payslip starts with gross pay — your salary for the period before deductions. Below that come the deductions: income tax (PAYE), National Insurance, often a workplace pension contribution, and a student loan repayment if you're above the threshold.

What's left after all of these is your net pay, the amount that actually arrives in your account. The gap between the two surprises a lot of people in their first job, so it's worth understanding each line.

Why take-home is less than you expect

A £25,000 'salary' doesn't mean £25,000 in your pocket. After income tax, National Insurance and pension contributions, your take-home is meaningfully lower — often around £20,000-£21,000 depending on your pension.

This matters for budgeting: always plan around your net monthly pay, not the headline salary. Salary calculators online can show your estimated take-home before you accept a job, which is well worth checking.

FAQ

Frequently Asked Questions

Why is my take-home pay so much lower than my salary? +

Because income tax, National Insurance and usually a pension contribution all come out before you're paid. A student loan repayment may too. On a typical starting salary these deductions can reduce your headline pay by roughly a fifth, which is why budgeting around net pay matters.

Is pension contribution taken from gross or net pay? +

It depends on the scheme, but many workplace pensions take contributions from your gross pay before tax, which gives you tax relief automatically. Others take it from net pay and claim relief afterwards. Your payslip will show the contribution, and it's worth knowing which method your employer uses.

How can I work out my take-home pay before starting a job? +

Use a free online salary or take-home pay calculator. Enter your gross salary and it estimates your income tax, National Insurance, pension and student loan deductions, leaving you with an approximate monthly net figure. This is far more useful for budgeting than the headline salary.
