How to Calculate Your Business Rates

Business rates are a tax on properties used for non-domestic purposes, such as offices, shops, pubs, and warehouses. To calculate your bill, you generally need two primary figures: the Rateable Value and the Multiplier (also known as the Uniform Business Rate).

The Basic Formula

Annual Rates Bill = (Rateable Value x Multiplier) – Any Eligible Reliefs

Key Components Explained

  • Rateable Value (RV): This is the VOA's estimate of your property's annual rent on the open market as of a specific valuation date (currently April 1, 2021, for the 2023 revaluation).
  • The Multiplier: For the 2024/25 tax year in England, the Small Business Multiplier is 49.9p (0.499) for properties with an RV below £51,000. For properties with an RV of £51,000 or more, the Standard Multiplier is 54.6p (0.546).
  • Small Business Rate Relief (SBRR): If your property's RV is £12,000 or less, you may receive 100% relief (meaning you pay nothing). For RVs between £12,001 and £15,000, the relief is tapered from 100% down to 0%.

Example Calculation

If you have a small shop with a Rateable Value of £13,500:

  1. Gross Bill: £13,500 x 0.499 = £6,736.50
  2. Relief: At £13,500, you are halfway through the taper (£15k – £12k range), receiving 50% relief.
  3. Relief Amount: £6,736.50 x 50% = £3,368.25
  4. Net Bill: £6,736.50 – £3,368.25 = £3,368.25 per year.
Note: This calculator provides an estimate for England. Business rates are handled differently in Scotland, Wales, and Northern Ireland. It also does not account for transitional relief, retail/hospitality discounts, or local authority specific grants.
