Depreciation Calculator

Year-by-year depreciation for straight-line, sum-of-the-years-digits and declining balance (including the DB factor), with remaining book value and remaining depreciable amount.

Worked example (T11): cost 11,000, salvage 1,000, 5 years → SL 2,000.00; SYD year 1 3,333.33; 200% DB year 1 4,400.00.

Worked example — three methods side by side (T11)

Cost 11,000, salvage 1,000, 5-year life. Year 1: SL 2,000.00; SYD 3,333.33 (= 10,000 × 5/15); 200% DB 4,400.00 (= 11,000 × 2/5). The DB schedule never drops the book value below salvage.

Frequently asked questions

What does DB factor 200 mean?

It is the declining-balance rate as a percent of straight-line: 200% (double declining) uses rate = 2/n per year; 150% uses 1.5/n.

Why does DB stop at salvage?

First-release rule: depreciation in the final years is limited so book value never falls below salvage. Switch to SL or SYD for comparison schedules.

How do I see year 3?

Set YEAR = 3 — DEP, RBV and RD update for that year of the chosen method.
