Council Tax Calculator
Estimate your annual and monthly council tax based on your property's band, your local annual charge, and any discounts or premiums.
Overview
Use this council tax calculator to estimate how much council tax you may pay each year and month. Enter your local annual band charge, choose how many months you pay over, and add any single person discount, other reduction, or council premium that applies.
How it works
The calculator starts with the annual council tax charge for your property band. It then applies the single person discount if selected, adds any extra percentage reduction you enter, and calculates any premium as a percentage of the standard annual charge. The final annual amount is the standard charge minus discounts plus premiums. The monthly estimate is the annual amount divided by the number of billing months.

Frequently asked questions
What does this council tax calculator estimate?
It estimates your yearly and monthly council tax after applying a standard annual band charge, discounts, and any premium or surcharge.
Do I need to know my council tax band?
You do not need to enter the band itself if you already know the annual charge for your property. If not, you can find the band and charge on your bill or local authority website.
Does this include the single person discount?
Yes. If you tick the single person discount box, the calculator applies a 25% reduction to the standard annual charge.
Can I include other council tax reductions?
Yes. You can enter an extra percentage reduction for other discounts or local support schemes if you know the rate that applies.
Can I calculate empty home or second home premiums?
Yes. Enter the premium percentage charged by your local authority to estimate how much extra may be added to the annual charge.
Why does my monthly amount look different from my actual bill?
Some councils collect payments over 10 months, others over 12, and your actual bill may also include adjustments, previous balances, or local charges not included here.
