Guide
How we calculate your comparison
- Income Tax (England or Scottish bands, auto-detected by city)
- National Insurance contributions
- Pension salary sacrifice
- Student loan repayments (if applicable)
- Personal Allowance taper for salaries above £100k
- Rent: average 1-bed flat (HomeLet Rental Index, ONS)
- Council Tax: Band D average (GOV.UK)
- Transport: monthly commute (TfL, local transit data)
- Groceries: single adult monthly spend (ONS Family Spending)
- Utilities: gas, electric, water (Ofgem, regional data)
- Broadband: average monthly cost (Ofcom)
- Disposable = net take-home pay - total monthly costs
- This is what you have left to spend, save, or invest
Cost-of-living figures are city averages. Your actual costs will vary based on neighbourhood, lifestyle, and personal choices. Use this as a starting point for comparison, not a guarantee. Tax rates and thresholds are for the 2025/26 UK tax year. This is not financial advice.
