Overview
This calculator estimates an annual UK business rates bill based on the property's rateable value and the current multiplier (poundage). It allows for reductions from specified reliefs and can apportion a bill for part-year occupations.
This tool provides an indicative figure for planning purposes only. The final bill is issued by your local billing authority and may include additional discretionary reliefs, transitional adjustments or mandatory reliefs not modelled here.

How to read the result
- What it means
- The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
- Calculation limits
- The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).
- Next step
- Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Glossary+−
- Rateable value
An assessment of the property's open market rental value on a fixed valuation date, used by the VOA to calculate business rates.
- Multiplier / Poundage
The pence-in-the-pound figure set by government used to convert rateable value into a business rates liability (entered here as pence, e.g. 49.9).
- Relief
A reduction or exemption from business rates (for example: small business rate relief, charitable relief, or local discretionary relief).
- Apportionment
Prorating the annual business rates bill for a partial-year occupation (expressed in weeks).
Key takeaways
Use rateable value and the applicable multiplier to estimate business rates: multiply the two, subtract known reliefs, and prorate if needed.
For authoritative information and to verify values, consult the VOA and your local billing authority. This tool is for estimation and planning only.

Worked examples
Standard annual calculation
Property with a rateable value of £12,000 and multiplier 49.9p, no reliefs.
Interpretation
£12,000 × 0.499 = £5,988 annual liability before any discretionary or transitional adjustments.
With reliefs and partial year
Property with rateable value £20,000, multiplier 49.9p, £2,000 reliefs, occupying for 26 weeks.
Interpretation
Annual: £20,000 × 0.499 = £9,980 − £2,000 reliefs = £7,980. Apportioned to half-year = £3,990.
Frequently asked questions
Where do I find the rateable value?
The Valuation Office Agency (VOA) lists rateable values for non-domestic properties. Search the VOA website for the property's listing.
What multiplier should I use?
Use the multiplier (poundage) published for the relevant billing year on GOV.UK. Multipliers are expressed in pence in the pound (e.g. 49.9). Some areas may apply additional supplements.
Does this calculator apply reliefs automatically?
No. You must enter relief amounts manually. The calculator does not determine eligibility for reliefs; contact your local authority or consult GOV.UK guidance for eligibility criteria.
Is this the final bill?
No. This is an indicative estimate. Your local billing authority issues the final bill, which may include adjustments, transitional relief, or mandatory/discretionary reliefs.
