Council Tax Calculator United Kingdom
This Council Tax calculator turns your council's Band D charge and your property's band into a 2026/27 bill, with monthly instalments over 10 or 12 months.
What it does
The Council Tax Calculator works out your annual Council Tax bill from your council's Band D charge and your property's valuation band, then shows the standard monthly instalments. Every band is a fixed statutory fraction of Band D — Band A is 6/9, Band H is 18/9 — so one Band D figure gives every band.

We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
annual charge = Band D charge × (band ninths ÷ 9); monthly (10) = annual ÷ 10; monthly (12) = annual ÷ 12
How it works
Enter the Band D annual charge published on your council's website and select your band. The tool looks up the band's ratio (in ninths of Band D), multiplies your Band D charge by it to get the annual bill, then divides by 10 and by 12 to show the two common instalment plans.
Where it is used
- Estimating your bill before you move to a new band or area
- Checking a Band A–C bill against the Band D headline figure
- Comparing paying over 10 versus 12 instalments
Worked example
With a Band D charge of £2,000.00 a Band A home pays a ratio of …, giving an annual bill of … — about … across ten instalments.
Council Tax pays for local services in England, Scotland and Wales: bin collection, social care, roads, libraries and part of policing and fire. What you pay depends on your home’s valuation band and the Band D charge set by your council. Enter the Band D amount your council publishes, choose your nation and band, and this calculator shows your annual bill and the monthly instalments.
How Council Tax bands work
Homes in England and Scotland sit in one of eight bands, A to H, according to their value on 1 April 1991. Wales uses a 2003 valuation and has a ninth band, I. The amount each band pays is not set separately: it is a fixed fraction of the Band D charge laid down by statute.
In England the fractions are ninths of Band D. Band D is 9/9; below it, Band A pays 6/9, Band B 7/9 and Band C 8/9; above it, Band E pays 11/9, Band F 13/9, Band G 15/9 and Band H 18/9, double the Band D bill. So in England a Band H home always pays three times as much as a Band A home in the same area. Wales uses the same ratios and adds Band I at 21/9. Scotland raised its ratios for Bands E to H in 2017, so there Band H pays about 2.45 times Band D.
Why the Band D figure matters
Because every band is tied to Band D, the Band D charge is the one number that varies from council to council. It bundles the charges of each tier of local government. In a two-tier area it typically combines the county council’s charge, the district or borough charge, an adult social care precept and precepts for the police and crime commissioner and the fire authority, and some areas add a parish or town council precept.
That is why two identical houses a few miles apart, in the same band, can have different bills. Use the Band D figure from your own council’s website, usually on its Council Tax charges page, rather than a national average.
A worked example
Your council’s Band D charge for the year is £2,000 and your home in England is in Band A. Band A pays 6/9 of Band D, so your annual bill is £2,000 × 6/9 = £1,333.33. Over the standard 10 instalments that is about £133.33 a month from April to January; over 12 months it is about £111.11.
With the same £2,000 Band D charge, a Band H home pays 18/9, twice Band D: £4,000 a year, or £400 a month over 10 instalments.
Paying over 10 or 12 months
By default Council Tax is billed in 10 monthly instalments from April to January, leaving February and March clear. In England and Wales you have had the right since April 2013 to ask your council to divide the same annual amount into 12 instalments. The total is identical; only the size of each payment changes. The calculator shows both figures so you can compare before asking for a change.
Discounts and reductions this tool does not model
The calculator gives the full charge for a band before any personal discount. A single adult living alone gets a 25% single person discount. Full-time students, and homes where everyone is disregarded, can be exempt. Low-income households may qualify for Council Tax Reduction, which in England each council runs under its own scheme. People with a disability may have their bill reduced to the band below through the Disabled Band Reduction Scheme. Empty homes and second homes can attract a premium rather than a discount. None of these are applied here; apply for them through your council.
Assumptions and limitations
The tool uses the statutory band ratios for England, Wales and Scotland, stored as parameters. It assumes the Band D charge you enter already includes all the relevant precepts. Northern Ireland’s domestic rates system is outside its scope. The result is the gross annual charge for the band; your actual bill may be lower after discounts, exemptions or Council Tax Reduction. Check the figures against your own council’s bill before budgeting.
