Depreciation Calculator
Calculate asset depreciation using straight-line or declining balance methods.
Assumptions used in this calculation
- Full-year depreciation, no mid-year convention: Assumes depreciation is applied in whole-year increments from the placed-in-service date, not prorated for a partial first year as some tax conventions require.
About this calculator
Business assets like equipment, vehicles and machinery lose value over time, and knowing exactly how much an asset is currently worth on the books matters for accounting, tax filings, and decisions about when to replace it, but the two standard depreciation methods produce quite different numbers for the same asset. This calculator takes an asset's cost, salvage value, useful life and years elapsed, and computes current book value under the straight-line method (an equal amount depreciated each year) or the declining balance method (a fixed percentage of the remaining book value depreciated each year, front-loading more depreciation into earlier years). Instead of manually building a year-by-year depreciation schedule by hand, which is easy to make a running total error in, this calculator gives the current book value directly and lets you compare how differently the two methods would treat the same asset, which matters for choosing the right method for tax purposes or financial reporting.
Worked example
₹1,00,000 cost, ₹10,000 salvage, 10-year life, 3 years elapsed
Result: Book value ≈ ₹73,000 (straight-line)
