How to Compare Job Offers in the UK
A higher salary does not always mean more money in your pocket. UK income tax, National Insurance contributions, and pension deductions can significantly reduce the difference between two offers. This calculator uses the 2024/25 UK tax bands to give you an accurate take-home comparison.
UK Income Tax Bands 2024/25
| Band | Taxable Income | Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Beyond the Salary: What Else to Consider
When comparing job offers, take-home pay is just one factor. Employer pension contributions, private health insurance, annual leave entitlement, flexible working, commuting costs, and career progression opportunities all affect the true value of a role. A job paying £5,000 less per year with a 30-minute shorter commute each way could save you over £2,000 in travel costs and hundreds of hours annually.
Does pension contribution affect take-home pay?
Yes — employee pension contributions are deducted from your gross salary before income tax is calculated (for most workplace pension schemes). This means a higher pension contribution actually reduces your income tax bill, making pension saving more tax-efficient than it might appear.
What is National Insurance?
National Insurance (NI) is a UK tax on earnings that funds state benefits including the NHS and State Pension. For 2024/25, employees pay 8% on earnings between £12,570 and £50,270, and 2% on earnings above £50,270.
