This calculator is provided for informational purposes only and should not be considered as financial or tax advice.

Rates and thresholds are sourced from HMRC and GOV.UK and are updated for the current tax year. Always verify results with HMRC or consult a qualified professional before making financial decisions.

How It Works

Business rates are calculated by multiplying your property's rateable value (RV) by the applicable multiplier set annually by the government. For 2025/26, the standard multiplier is 51.2p in the pound for properties with an RV of £51,000 or above, and the small business multiplier is 49.9p for properties below that threshold. The rateable value is an estimate of the open-market annual rent for the property as assessed by the Valuation Office Agency (VOA).

Small Business Rate Relief (SBRR) applies if your single property has an RV below £15,000. Properties with an RV of £12,000 or below receive 100% relief—paying zero business rates. Between £12,001 and £15,000, the relief tapers on a sliding scale. If you occupy multiple properties, your eligibility is based on the combined RV, and SBRR may be reduced or unavailable.

Additional reliefs may apply: rural rate relief for shops and post offices in designated rural areas, charitable relief at 80% for qualifying charities, and the retail/hospitality/leisure relief scheme which has provided up to 75% discount in recent years. Transitional relief caps annual increases or decreases following a revaluation to smooth bill changes. Your local council issues the bill and administers collection.

Business rates for a shop with £20,000 rateable value

Rateable value of the property: £20,000.
Property RV is below £51,000, so the small business multiplier applies: 49.9p.
Basic rates bill: £20,000 × 0.499 = £9,980 per year.
RV exceeds £15,000, so no Small Business Rate Relief applies.
Annual business rates payable: £9,980, typically paid in 10 monthly instalments of £998.
