How the calculator works
This calculator answers a question most online budget tools sidestep: what does it genuinely cost to live in a specific UK area, factoring in your household and lifestyle, not just a vague national average.
Every figure on this page is pulled from official government data specific to the area you choose. Rent comes from the ONS Price Index of Private Rents at the bedroom count you select. Council tax is the exact 2026-27 figure for that local authority and band. Energy is taken from the Ofgem price cap, mapped to the area's electricity region. Water is the average annual bill from the company that serves the area. We cover 370+ local authorities across England, Scotland and Wales.
As you change your selections, the estimate updates instantly. There is no "calculate" button to press. The breakdown shows you exactly where your money goes, and the comparison line tells you how your number stacks up against the national average for the same kind of household.
Most cost of living calculators online lean on regional averages or ask you to enter your own figures. Ours does the opposite: we pre-fill everything from real area-level data, and you adjust only your personal situation. That makes the result useful as a comparison, not just a budget.
What is included in the cost of living
Rent is taken from the ONS Price Index of Private Rents, specific to your chosen area and bedroom count. We use median figures because they are less skewed by outlier properties than averages.
Council tax uses the exact rate for the specific local authority and the band you select. Data comes from MHCLG for England, the Scottish Government, and the Welsh Government. The 25% single person discount is applied automatically when you select Single as your household type.
Energy is based on the Ofgem price cap for a typical dual-fuel household paying by direct debit, mapped to the area's electricity region. This covers gas and electricity combined.
Water is the average annual bill from the water and sewerage company that serves the area, sourced from Water UK and Discover Water for England and Wales, and Scottish Water in Scotland.
Groceries are a national estimate from the ONS Family Spending Survey, scaled by household size. This is the one category that does not vary by area in our calculation. Single £220, couple £350, family with one child £420, rising with each additional child.
Transport uses your chosen mode. Public transport costs are higher in London than elsewhere. Running a car is treated as a national average covering fuel, insurance, tax and routine maintenance.
Childcare only appears in the breakdown for family households with one or more children. The figure is a blended estimate that accounts for free childcare hours. Actual costs vary widely depending on the type of care and local availability.
How costs vary across the UK
The gap between the cheapest and most expensive UK areas is wider than most people expect. On our calculation for a single person, Dumfries and Galloway comes out around £1,001 a month, while Kensington and Chelsea is over £3,249. That's a difference of more than £2,248 every month, before groceries or transport are factored in.
Rent is the biggest driver of regional variation by a long way. A one-bed flat that costs £400 a month in parts of the North East or rural Scotland can easily cost five or six times that in central London. Bedroom count amplifies the gap further.
Council tax varies by a factor of nearly three across the country. Scotland tends to sit at the lower end. England has the widest spread, with some boroughs charging well over £2,500 a year at Band D and others under £1,500. Wales sits in the middle.
Energy and water are comparatively uniform. The Ofgem cap is set nationally, with only modest regional variation in distribution costs. Water bills differ by company, not by household location within a company's area. Explore our cheapest places rankings and best value rankings for deeper cuts of the same data.
Tips for using your results
Band D is the standard benchmark for council tax and is the safe default if you don't know your property's band. To find the actual band, check your local council's website. Smaller flats and terraced houses are usually A to C; larger detached homes are typically E and above.
The rent figures used here are medians. Roughly half of the available properties at any given bedroom count will be cheaper, and half will be more expensive. Older flats and properties further from the centre tend to sit at the lower end.
Mortgage costs depend heavily on the rate you actually get, which varies by lender, credit history and the size of your deposit. We use 4.5% as a representative rate. A 1% movement in rates makes a meaningful difference to the monthly payment, especially on longer terms.
Grocery costs vary as much by where you shop as by where you live. A weekly Aldi shop in central London still costs roughly the same as one in rural Wales. The figures we use are national averages from the ONS Family Spending Survey.
The calculator gives a useful baseline. It does not give a budget. Your actual costs will depend on specific choices: the property you rent or buy, the tariff you're on, how much you drive, where you shop. Use this to compare areas, then build a budget on top.
Methodology
Rent uses the ONS Price Index of Private Rents (PIPR), at the bedroom count selected, for the chosen local authority. Council tax is the 2026-27 figure for the selected band, inclusive of major precepts, sourced from MHCLG, the Scottish Government and the Welsh Government. Energy uses the Ofgem price cap for a typical dual-fuel direct-debit household, mapped to the area's electricity region. Water is the average annual bill for the company serving the area.
Grocery estimates come from the ONS Family Spending Survey and are scaled by household type. Transport estimates are based on national averages for monthly travel costs, with a higher figure used for London public transport to reflect TfL pricing. Childcare is a blended estimate of £200 per child per month that accounts for the government's free hours entitlement; actual costs vary widely.
The mortgage estimate uses the standard annuity formula at a 4.5% annual rate over your chosen term, with the principal calculated as the area's median house price minus your selected deposit percentage.
