Enter amounts without commas or with them; rates are percentages (5 for 5%). Negative amounts are allowed where a sign means money paid out.
Key facts
straight line = (cost − salvage) ÷ life declining balance = book value × factor ÷ life, never below salvage sum of the years' digits = (cost − salvage) × years left ÷ (n(n + 1) ÷ 2) partial first year: that share of a year, the rest in an extra last year
Partial years
With a partial first year, each method takes that share of its first full year and the rest falls in an extra year at the end. Mid-month counts the month placed in service as half a month.

- Rates are nominal annual rates compounded as you choose; payments at a different frequency use the equivalent periodic rate.
