Estimate the taxable portion of a capital gain, approximate tax owed, and after-tax proceeds for Canadian planning. This tool is useful for investors reviewing stocks, ETFs, crypto, rental property, or business-share scenarios before they talk to a qualified tax professional.
Important: This calculator applies a simplified two-tier inclusion-rate model for planning. Confirm current tax rules and timing with CRA guidance or a qualified tax professional before filing or selling.
Adjusted cost base: what you originally paid, including adjustments where relevant.
Current preview: capital gain of $49,500
What this calculator does
The calculator starts with sale price, adjusted cost base, selling expenses, province, and income. It estimates the capital gain, taxable portion, tax owed, and after-tax proceeds under a simplified Canadian capital-gains model.
How to use it
Choose the asset type, enter your purchase price or adjusted cost base, sale price, selling expenses, province, and income. Use the TFSA toggle only when the asset was held in a qualifying TFSA position.
Inputs explained
The cost base used to estimate the gain. Real ACB can include adjustments, commissions, and reinvested distributions.
The gross sale proceeds before expenses and tax.
Commissions or eligible selling costs that reduce the modeled gain.
Used to estimate the marginal tax rate applied to the taxable capital gain.
Example calculation
With a purchase price of $50,000, sale price of $100,000, and selling expenses of $500, the current preview shows a capital gain of $49,500. Click calculate to estimate the taxable portion and tax owed.
How to read your result
The capital gain is not always the amount taxed. The taxable portion is the amount included in income, while after-tax proceeds estimate what remains after the modeled tax. If the sale affects registered-account planning, compare the result with the TFSA calculator or RRSP calculator.

Real Canadian scenario
Assume an Ontario resident earning $80,000 bought an ETF for $50,000, sold it for $100,000, and paid $500 in selling costs. The calculator treats the $49,500 gain as a taxable-account estimate, not a tax return.
The taxable portion is estimated using the calculator's current capital-gains model and the selected marginal-rate assumption.
The result is useful for deciding whether the sale is material enough to review before year-end, especially if other gains, losses, or income changes are also in play.
Limitation: This does not model every adjusted-cost-base issue, superficial loss rule, crypto recordkeeping issue, principal-residence rule, or business-share exemption detail.
