Documentation
Use this calculator to estimate the UK alcohol duty owed on a batch of beer, cider, wine, spirits, or other fermented beverages. The calculator applies the official HMRC duty rates per litre of pure alcohol (LPA) based on the beverage type and ABV band. It supports both standard and reduced draught rates.
- Select the Beverage Type from the dropdown menu. Options include Beer, Cider (Still), Sparkling Cider, Spirits or Spirit-Based Products, Wine (Including Sparkling Wine), and Other Fermented Products.
- Enter the ABV (%) of the product. The calculator rounds ABV down to the nearest 0.1% as required by HMRC rules. You may enter decimals, fractions (such as 4/5), or mixed numbers (such as 5 1/2).
- Enter the Volume of the batch. Supported formats include decimals, fractions, and mixed numbers.
- Select the Volume Unit. Options include Litres, UK Gallons, US Gallons, and traditional beer cask units (Firkin, Kilderkin, Barrel, Hogshead, Butt, and Tun).
- Check the Draught product checkbox if the product qualifies for the reduced draught duty rate. Draught rates apply only to products with an ABV below 8.5%.
- Press Calculate or allow the auto-calculation to update results as you type.
- Press Reset to clear all fields and restore default values.
- Open Settings to select a different rate period or to enable step-by-step calculation display.
The core formula is: Total Duty = Litres of Pure Alcohol (LPA) x Duty Rate (GBP per LPA). LPA is calculated as Volume (in litres) x (ABV / 100). The total duty amount is rounded down to the nearest penny, and ABV is rounded down to the nearest 0.1%, following HMRC guidelines.
