How the Compare Two Salaries Calculator Works
Comparing job offers across UK cities is harder than it looks. A £55,000 salary in London might seem better than £42,000 in Birmingham — but once you factor in rent, transport and food, the picture often flips. Our calculator does the maths for you using HMRC 2025/26 tax rates and real cost-of-living data from 40+ UK cities.
The four-step calculation
- Gross to net pay — We apply UK income tax (Personal Allowance £12,570, basic 20%, higher 40%, additional 45%) and employee National Insurance (8% above £12,570, 2% above £50,270).
- Pension deduction — Optional percentage applied as salary sacrifice (reduces taxable income).
- City living costs — Annual rent + transport + food are subtracted from net pay using city-specific data.
- Real disposable income — What's actually left in your pocket after the essentials. This is the number that matters.
UK 2025/26 tax bands used
| Band | Range | Rate |
|---|---|---|
| Personal Allowance | £0 – £12,570 | 0% |
| Basic rate | £12,571 – £50,270 | 20% |
| Higher rate | £50,271 – £125,140 | 40% |
| Additional rate | £125,141+ | 45% |
Plus employee National Insurance: 8% on earnings between £12,570 and £50,270, then 2% above £50,270.
Cost of living index — methodology
Each of the 40+ UK cities in the dropdown has three benchmark monthly figures: a one-bedroom flat rent in a typical area, a monthly public transport pass, and average grocery costs for one adult. Sources: ONS Private Rental Index, Numbeo Cost of Living, Rightmove and TfL/local authority data, calibrated to 2025/26.
London vs the rest — the rent gap
London rent (£2,100/month for a 1-bed) is more than double the UK average. The next most expensive cities are St Albans (£1,700), Guildford (£1,620), Oxford (£1,550) and Cambridge (£1,500). At the other end, Hull, Bradford and Stoke-on-Trent come in around £700/month. That's a £16,800/year rent saving simply by moving 200 miles north — equivalent to a £24,000 pay rise pre-tax.
Common comparison scenarios
- £60,000 London vs £45,000 Manchester — Manchester typically wins by ~£3,000/year of real disposable income.
- £40,000 Birmingham vs £35,000 Sheffield — Roughly tied; depends on commute.
- £75,000 London vs £55,000 Leeds — Leeds wins by ~£2,500 once cost-of-living is factored in.
- £90,000 London vs £70,000 Edinburgh — London wins for the first time at this salary point — but Edinburgh's quality-of-life gap is substantial.
Limitations to keep in mind
- Council tax, utilities, broadband, dining out and entertainment are not included — these typically add £300–£500/month uniformly across cities.
- Rent figures are city averages — central London Zone 1 or premium areas of any city will be 30–60% higher.
- The calculator uses rUK income tax for both scenarios; Scottish residents above ~£28k pay slightly more income tax.
- Quality-of-life factors (commute time, weather, social life, family proximity) cannot be modelled.

Frequently asked questions
How does the compare two salaries calculator work?
Enter two gross salaries and pick a UK city for each. We apply UK 2025/26 income tax and National Insurance, then subtract typical monthly living costs (rent, transport, food) for the chosen city. The result is your real disposable income.
Why is £40k Manchester often better than £50k London?
London rent averages around £2,100/month vs £980 in Manchester — a £13,440/year difference. Add higher transport (£165 vs £75) and food costs, and a London salary typically needs to be £18,000–£22,000 higher to match Manchester's real disposable income.
Which UK city has the best disposable income?
For mid-range salaries (£30k–£50k): Stoke-on-Trent, Hull, Bradford, and Sheffield consistently top the league. For higher earners (£70k+): Birmingham, Manchester and Leeds become very strong.
What costs are included?
Monthly rent for a one-bedroom flat in a typical area, monthly public transport pass, and average monthly grocery costs for one adult. These three items represent 60–75% of a single person's monthly outgoings.
Are these UK city cost figures accurate for 2025/26?
Figures are calibrated to 2025/26 averages from ONS, Numbeo, Rightmove and TfL data. Actual costs vary within cities — central Zone 1 London is much higher than the £2,100 average. Use the figures as a benchmark, not a quote.
Does the calculator account for Scottish income tax rates?
This calculator uses UK-wide rUK rates (20%/40%/45%) for both salaries to keep the comparison apples-to-apples. Scottish residents actually pay slightly more above ~£28,000. For exact Scottish band calculations use our Salary Calculator.
