# Depreciation Calculator

> Straight-line, declining balance, double-declining and sum-of-years depreciation schedules.

Depreciation spreads an asset's cost over its useful life. Straight line charges the same amount each year; declining balance and sum of the years' digits front-load the charge to match assets that lose value fastest when new. All methods write off the same total — cost minus salvage value.

## FAQ

### Which method should I use?

That is usually decided by your tax authority and accounting standard, not by preference. Straight line is the default in most jurisdictions; accelerated methods may be permitted or required for particular asset classes. Check with an accountant before filing.
