CCA calculator
Pick the class, enter the cost, see the year's maximum claim with the half-year rule applied — and what carries forward. The classic math, clearly labelled where modern accelerated rules may improve on it.
Classic half-year-rule math. Accelerated first-year rules (AII) have modified this for eligible property in recent years — confirm current-year treatment with your accountant.
Class, rate, and the half-year rule
Capital cost allowance is Canada's tax depreciation. Each asset belongs to a CRA class carrying a maximum annual rate, and the claim is generally calculated on the declining undepreciated capital cost rather than on the original price.
In the year you acquire an asset the claim is usually restricted to half the normal amount — the half-year rule. Buy $10,000 of Class 8 (20%) equipment and year one claims $1,000 rather than $2,000, leaving $9,000 of UCC; year two claims 20% of $9,000, or $1,800.
CCA is not your book depreciation
The depreciation in your financial statements follows your own policy and audience; CCA follows the CRA's rules. They are meant to differ, and keeping them as separate figures is correct rather than sloppy.
CCA is also permissive rather than mandatory — you may claim less than the maximum in a year, which occasionally matters for a business with losses. That is a conversation for your accountant, not a calculator.
