# DDB Function Declining Balance Depreciation Calculator

Calculates depreciation using the Declining Balance method. Formula: ddb(cost, slvg, life, period, fct)

ddb: The result of the formula.

cost: The initial cost of the asset. 0 < cost

slvg: The salvage value. 0 <= slvg <= cost

life: The life of the asset. 0<= life

period: The period of the depreciation. 0 < period

fct: The depreciation rate. 0 < fct. Typically 1.5-2 and not 150 - 200.

## Example 1

Calculate the annual depreciation of a 10,000 asset with a salvage value of 1,000 and a life of 5 for period 1 with a depreciation factor of 2.
