Capital gains calculator
Work out a capital gain or loss from the proceeds, the adjusted cost base and the cost of selling, see how much of it is taxable, and optionally estimate the 2026 federal and Ontario tax on it alongside your other income.
An illustration of how proceeds become a capital gain and a taxable gain, not your result.

How the calculation works
Capital gain or loss = proceeds of disposition − (adjusted cost base + outlays and expenses of selling). For an individual, 50% of a capital gain is the taxable capital gain, which is added to income. For a loss, 50% is the allowable capital loss. The optional estimate is the 2026 tax on your other taxable income plus the taxable gain, minus the 2026 tax on your other taxable income alone.
A worked example
At illustrative figures, property sold for $100,000 with an adjusted cost base of $60,000 and $2,000 of selling costs produces a capital gain of $38,000. Half, or $19,000, is the taxable capital gain. With $80,000 of other taxable income, the estimated federal and Ontario tax on the gain is $5,708.51, about 15% of the whole gain, which leaves roughly $32,291.49 after tax. If the same sale had produced a $10,000 loss, the allowable capital loss would be $5,000.
Assumptions and limits
Only the taxable part of a gain is taxed, and the 50% inclusion rate is the one the CRA publishes for individuals. The tool does not model the principal residence exemption, the lifetime capital gains exemption, capital gains reserves, superficial loss rules, the alternative minimum tax, partial dispositions, foreign currency conversion, gifts of publicly listed securities or the treatment of corporations and trusts. An allowable capital loss cannot be deducted from other income: it can generally be applied only against taxable capital gains of the year, the three previous years or later years, and the tool does not apply it. Adjusted cost base is often the hardest number to get right, because it includes purchase costs and can change with reinvested distributions, returns of capital and improvements. Anything sold must be reported on your return even when no tax is payable.
