C Program to Calculate Depreciation Amount

C Program To Calculate Depreciation Amount

This c program is used to find the depreciation amount after few years.

Depreciation Amount After Few Years Algorithm

Current Value = (principal amount * power(1-(rate per annum/ 100), year))
Depreciation Amount = Principal Amount - Current Value

Depreciation Amount Few Years Ago Algorithm

Total Value = (current amount / power(1-(rate per annum/ 100), year))
Depreciation Amount = Total Value - current
