Canada Capital Gains Calculator
Use this calculator to estimate your capital gain, taxable capital gain, and estimated tax in Canada. Enter your amounts in CAD.
How capital gains are taxed in Canada
When you sell a capital asset for more than its adjusted cost base, the difference is generally a capital gain. In Canada, only a portion of that gain is included in your taxable income, based on the applicable inclusion rate. You then pay tax based on your marginal tax bracket.
This page gives you a practical calculator and plain-English guide so you can estimate taxes before you sell assets like stocks, ETFs, cottages, rental properties, crypto, or other investments.
Taxable Capital Gain = Net Capital Gain × Inclusion Rate
Estimated Tax = Taxable Capital Gain × Marginal Tax Rate
What to enter in the calculator
1) Sale Price (Proceeds)
This is what you sold the asset for. For a property sale, this is usually the purchase price agreed on by the buyer. For investments, it is the amount you received after disposition.
2) Purchase Price + ACB Additions
Your adjusted cost base starts with the original purchase price, then includes eligible acquisition costs and capital improvements. These additions reduce your gain.
3) Selling Costs
Include direct selling costs such as commissions and legal fees. These reduce your gain because they are outlays associated with disposition.
4) Capital Losses
Net capital losses from prior years (or current-year losses) can often reduce your capital gain. The calculator lets you estimate this effect quickly.
5) Inclusion Rate and Tax Rate
The inclusion rate determines what share of your net gain becomes taxable income. Your marginal tax rate then estimates the tax impact. Tax law can change, so verify rates with CRA guidance or your tax professional.
Worked example
Suppose you sold an investment property with these numbers:
- Sale price: $650,000
- Purchase price: $420,000
- Buying costs: $8,000
- Capital improvements: $25,000
- Selling costs: $30,000
- Capital losses applied: $10,000
- Inclusion rate: 50%
- Marginal tax rate: 35%
Then your estimated gain is calculated after ACB and selling costs, reduced by losses, multiplied by the inclusion rate, then by your tax rate. This gives a planning estimate before filing.
Asset types commonly involved in Canadian capital gains
Stocks and ETFs
Track your ACB carefully, especially after multiple buys/sells, DRIPs, and corporate actions. Poor records can cause overpayment of taxes.
Rental property or cottage
Disposition of non-principal residences can trigger significant capital gains. Major renovations may increase ACB if documented correctly.
Crypto assets
Most crypto dispositions are taxable events in Canada. Keep transaction-level records with fair market value at the time of each trade.
Common mistakes to avoid
- Forgetting to include acquisition and disposition costs.
- Confusing regular repairs with capital improvements.
- Ignoring ownership split between spouses/partners.
- Using the wrong inclusion rate for your planning year.
- Assuming principal residence exemption automatically applies in all cases.
Documents you should keep
- Purchase and sale agreements
- Legal invoices and commission statements
- Receipts for capital improvements
- Broker statements and transaction history
- Prior-year notices of assessment showing loss carryforwards
FAQ
Does selling my principal residence always create tax?
Not necessarily. If the property qualifies fully under principal residence exemption rules, the gain may be exempt. Complex cases (such as partial rental use or change in use) should be reviewed professionally.
Can capital losses reduce all income?
Generally, net capital losses are applied against capital gains, not ordinary employment income. There are carryback and carryforward rules to consider.
Is this calculator enough to file taxes?
No. It is designed for estimation and planning. Filing still requires complete records and correct CRA forms.
