Gross vs Net Salary — What Is the Difference?
Salary Basics · March 15, 2026 · 6 min read
When you receive a job offer, you are quoted a gross salary. When you check your bank account on payday, you receive your net salary. The gap between these two numbers — which can easily be 25–45% of your gross pay — is what you pay in income tax, social contributions, and other mandatory deductions.
Understanding this difference is one of the most important pieces of financial literacy for any employee. It affects how you evaluate job offers, negotiate pay, budget for monthly expenses, and plan for the future.
What is gross salary?
Gross salary is the total compensation your employer agrees to pay you before any deductions. It is the number in your employment contract, on job adverts, and in salary surveys. Gross salary includes your base pay, and may also include regular bonuses or allowances that are treated as salary for tax purposes.
Gross salary does not typically include employer pension contributions (which are paid on top), employer National Insurance (in the UK) or superannuation (in Australia) — these are additional employment costs paid by your employer that never appear in your payslip at all.
What is net salary (take-home pay)?
Net salary — also called take-home pay or net pay — is what actually arrives in your bank account after all mandatory deductions have been subtracted. It is the money you actually have available to spend, save or invest.
The main deductions that turn gross salary into net salary are:
Income tax: The largest deduction for most earners. In the UK, Australia, Canada and Ireland, income tax is progressive — the higher your income, the higher the rate on each additional pound/dollar/euro. The rates and thresholds vary by country and, in the UK, by whether you live in Scotland.
Social contributions: These fund public services and insurance schemes. In the UK, this is National Insurance (8% on typical earnings). In Australia, it is the Medicare Levy (2%). In Ireland, it is USC and PRSI combined (up to 12%). In Canada, it is CPP and EI (approximately 7%). In India, it is EPF (12% of basic salary).
Student loan repayments: In the UK and Australia, student loan repayments are collected through the payroll system. UK Plan 2 deducts 9% above £27,295; Australian HELP repayments range from 1% to 10% above $54,435.
Pension contributions: In the UK, auto-enrolment minimum contributions are 5% employee + 3% employer = 8% of qualifying earnings. These reduce take-home pay but also reduce your tax bill and build retirement savings.
The gross-to-net calculation: a step-by-step example
Let us walk through a concrete UK example for a £50,000 salary in 2025/26.
Step 1 — Start with gross salary: £50,000.
Step 2 — Subtract the personal allowance: The first £12,570 is tax-free. Taxable income = £37,430.
Step 3 — Calculate income tax: All £37,430 falls in the 20% basic rate band (since £50,000 is below the higher rate threshold of £50,270). Income tax = £37,430 × 20% = £7,486.
Step 4 — Calculate National Insurance: 8% on earnings between £12,570 and £50,000 = £37,430 × 8% = £2,994.
Step 5 — Subtract all deductions: £50,000 − £7,486 − £2,994 = £39,520 take-home (£3,293/month).
Effective tax rate (all deductions / gross): £10,480 / £50,000 = 21.0%. The marginal rate on the last pound is 28% (20% + 8%).
Why the gross-to-net gap grows at higher incomes
The UK income tax system is progressive, meaning higher earners face higher rates on their additional income. On a £40,000 salary, effective total deductions are approximately 19%. On £60,000, effective deductions are approximately 28%. On £100,000, effective deductions reach approximately 38%.
The gap grows even more steeply between £100,000 and £125,140, where the personal allowance is tapered away, creating an effective marginal rate of 60% (40% income tax + 2% NI + 20% personal allowance tapering effect) on each additional pound in that range. This is one of the quirks of the UK tax system that many high earners are unaware of.
Gross vs net for self-employed workers
Self-employed individuals do not have an employer deducting tax automatically. Instead, they pay income tax and Class 4 National Insurance through self-assessment — meaning they may need to set aside 25–40% of income to cover their annual tax bill. There is no employer NI contribution for the self-employed, making the total NI rate lower (9% Class 4 below upper profits limit, 2% above), but also meaning no employer pension contribution.
How to use gross vs net salary when comparing job offers
Job offers are always quoted as gross salary, but what you can actually spend is your net. When comparing two offers, always convert both to net take-home pay before comparing. A salary increase that pushes you into the higher rate tax band (above £50,270 in the UK) means you keep only 60p of every additional pound — the marginal rate of 40% income tax plus 2% NI means the government takes 42p of each extra pound.
Similarly, a salary that comes with employer pension contributions effectively adds hidden value. An employer that matches 5% of your salary in pension contributions is offering £2,500 of additional compensation on a £50,000 salary — even though this does not appear in your net take-home.
