Question: how to calculate wdv rate of depreciation in excel?
Answer: It uses a fixed rate to calculate the depreciation values. The DB function performs the following calculations. Fixed rate = 1 - ((salvage / cost) ^ (1 / life)) = 1 - (1000/10,000)^(1/10) = 1 - 0.7943282347 = 0.206 (rounded to 3 decimal places). Depreciation value period 1 = 10,000 * 0.206 = 2,060.00.
