Overview
This calculator estimates the principal residence exemption (PRE) under Canadian tax rules to determine the exempt portion of a capital gain when you sell a property that has been your principal residence for some, or all, of the time you owned it.
It follows the Canada Revenue Agency (CRA) approach for calculating the exempt portion: exempt fraction = (years designated + 1) / (years owned + 1), prorated by ownership share. Use the results as an estimate and consult CRA guidance or a tax professional for complex situations.

How to read the result
- What it means
- The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
- Calculation limits
- The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).
- Next step
- Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Glossary+−
- Adjusted Cost Base (ACB)
The original cost of the property plus allowable acquisition expenses; used to calculate capital gain.
- Capital Gain
Proceeds of disposition (sale proceeds less selling costs) minus the adjusted cost base; a portion may be taxable if not fully exempt.
- Principal Residence Exemption (PRE)
A tax rule that can exempt some or all of a capital gain on the sale of a property that has been designated as a principal residence for a given number of years.
- Ownership Share
The percentage of the property owned by the taxpayer; the PRE is prorated by ownership share if the property is co-owned.
Key takeaways
Use the inputs to estimate the exempt portion of a capital gain under the principal residence exemption and the resulting taxable capital gain.
Results are estimates. Always review CRA guidance and consider professional tax advice for reporting and elections.

Worked examples
Example 1 — Family home used as principal residence
You bought a house in Ontario for $300,000, paid $5,000 in purchase costs, and sold it 10 years later for $600,000 with $15,000 selling costs. You owned 100% and lived in it as your principal residence for 9 of the 10 years.
Interpretation
Adjusted cost base = $305,000. Net proceeds = $585,000. Capital gain = $280,000. Exempt fraction = (9 + 1) / (10 + 1) = 10/11 ≈ 90.91%. Exemption ≈ $254,545. Taxable capital gain ≈ $25,455. Consult CRA for reporting requirements; a disposition of a principal residence must be reported on your tax return for the year of sale if required by current CRA rules.
Example 2 — Partial ownership / part-time residence
Two siblings co-own a cottage 50/50. Bought for $200,000 (no purchase costs), sold after 8 years for $400,000 with $10,000 selling costs. Only one sibling lived there as a principal residence for 4 of the 8 years.
Interpretation
Adjusted cost base = $200,000. Net proceeds = $390,000. Capital gain = $190,000. Exempt fraction for the owner who designated the cottage = (4 + 1) / (8 + 1) = 5/9 ≈ 55.56%. Prorated by 50% ownership: exemption ≈ $52,778. Taxable capital gain for that owner ≈ $137,222 × 50% ownership = approximately $68,611 (this example shows how ownership share and designation interact; reporting depends on elections and CRA rules).
Frequently asked questions
What official guidance does this follow?
This calculator follows the Canada Revenue Agency's guidance on the principal residence exemption and capital gains. See CRA: "Principal residence" and "Dispositions of capital property" for detailed rules and examples.
Does this replace professional tax advice?
No. The calculator provides estimates only. For complex cases (change in use, spousal rollovers, multiple properties, or co-ownership disputes), consult a tax professional or the CRA.
Why is there a '+1 year' in the formula?
CRA's formula for calculating the exempt portion typically adds one year to the numerator (years designated) to allow for the year of acquisition or disposition in many cases. The calculator applies that conventional adjustment by default but provides an option to toggle it.
