Depreciation calculator
Build a yearly depreciation schedule — straight line or declining balance — with book values.
How to use
- Enter asset cost, salvage value, and useful life.
- Pick straight line or declining balance (with a rate).
- Read the yearly schedule.
What it supports
Straight line spreads (cost − salvage) evenly; declining balance applies your rate to each year's opening book value and stops at salvage. Useful life 1–100 years, rate 0–100%. This is the simple schedule — tax-rule methods (200% DB, MACRS, half-year conventions) are not modeled.
