Example: if a company purchases a computer worth £1,000 (with a projected lifetime of 4 years), and you want to depreciate it at a 20% reducing balance you would simply multiply £1,000 by 20% which gives you a value of £200. For the next year, you'd start the depreciation calculation from the original cost minus the depreciation cost.
