What Is the Rent vs Buy Canada Calculator?
Whether buying or renting builds more wealth over time depends on more than the headline mortgage payment versus rent — it depends on home appreciation, property tax, maintenance costs, and critically, what a renter does with the money they're not spending on a down payment and higher housing costs. This calculator projects net worth under both scenarios: buying (home equity built through paying down the mortgage and appreciation) versus renting and investing the down payment plus any monthly savings compared to buying.
This is a genuinely close call in many Canadian markets today, where home prices relative to rent have grown significantly — this calculator lets you test your own specific numbers rather than relying on a general assumption about which is "better."
Rent vs Buy Canada Calculator Formula
Buy Net Worth = Home Value − Remaining Mortgage Balance
Rent Net Worth = Down Payment + Monthly Savings, Invested and Compounded
How Is the Rent vs Buy Canada Calculator Calculated?
This calculator simulates both paths month by month over your chosen comparison period. For buying, it uses Canada's semi-annual compounding mortgage formula to track the declining balance, adds property tax and maintenance as ongoing costs, and grows the home value at your expected appreciation rate — the final net worth is home value minus whatever mortgage balance remains.
For renting, the down payment is invested from day one. Each month, if the total cost of buying (mortgage payment, tax, and maintenance) would have exceeded the comparable rent, that difference is also invested — reflecting money a renter could genuinely set aside instead of spending on higher homeownership costs. The full portfolio compounds at your expected investment return rate throughout the comparison period.
Rent vs Buy Canada Calculator Example
A $600,000 home with a $120,000 (20%) down payment at 4.5% over 25 years, compared against $2,200 monthly rent over 10 years (6% investment return, 3% appreciation): renting and investing wins by about $65,142, since the monthly cost of owning here is substantially higher than the comparable rent, leaving a lot for the renter to invest.
A more affordable $400,000 home with a $80,000 down payment at the same rate and terms, against the same $2,200 rent: buying wins by about $76,299, since the ownership costs here are much closer to (and eventually build more equity than) the rent comparison.
A $500,000 home with a $100,000 down payment at 5% over 25 years, against $2,000 rent, compared over just 5 years: the two paths land within about $9,014 of each other, with renting slightly ahead — a close result showing how sensitive this comparison is to the specific numbers and timeframe.

Common Rent vs Buy Canada Calculator Scenarios
Scenario 1
Deciding whether to buy a home or continue renting in your current market.
Scenario 2
Comparing a specific home listing against your current rent to see which builds more wealth.
Scenario 3
Understanding how sensitive the rent-vs-buy decision is to appreciation and investment return assumptions.
Scenario 4
Testing how a longer or shorter time horizon changes which option comes out ahead.
Scenario 5
Explaining to someone why "renting is throwing money away" isn't always true, depending on the numbers.
Understanding Your Result
This is a projection based on the assumptions you enter — home appreciation and investment returns are genuinely uncertain and vary significantly over real time periods, so treat the result as one plausible scenario rather than a guaranteed outcome. Small changes to appreciation or investment return assumptions can meaningfully shift which side comes out ahead, especially over shorter comparison periods.
This calculator also doesn't capture non-financial factors — stability, control over your living space, and flexibility to relocate all matter for a real decision beyond the pure net worth numbers shown here.
Tips
- Try running this calculator with a range of appreciation and investment return assumptions (both optimistic and conservative) to see how sensitive your specific comparison is, rather than relying on a single scenario.
- This calculator doesn't include closing costs (land transfer tax, legal fees, CMHC insurance if applicable) or selling costs (realtor commissions) — both are real costs that would shift the comparison somewhat toward renting if included.
- A longer comparison horizon generally favours buying more, since mortgage paydown and appreciation compound over more years while rent, in reality, tends to rise over time too (not modeled here for simplicity).
- If you're genuinely unsure how long you'll stay in one place, renting reduces the risk of near-term selling costs eating into any home appreciation gained.
- The monthly cost comparison (mortgage + tax + maintenance vs rent) is often the single biggest driver of which side wins — a market where ownership costs are close to rent tends to favour buying, while a market with a large gap tends to favour renting and investing.
Common Mistakes
- Assuming buying is automatically better because "rent is money you'll never see again," without accounting for what a renter could earn by investing the money buying would otherwise cost.
- Not accounting for property tax and maintenance as real, ongoing costs beyond just the mortgage payment.
- Using an unrealistically high or low appreciation rate without testing a range of scenarios.
- Ignoring closing and selling costs, which this calculator doesn't model but which meaningfully affect a real-world comparison.
- Treating a short comparison period (a few years) as equally reliable as a longer one, when short-term results are much more sensitive to timing and assumptions.
Frequently Asked Questions
Is buying always better than renting in the long run?
Not necessarily — it depends heavily on the relationship between home prices, rents, appreciation, and investment returns in your specific situation. This calculator lets you test your own numbers rather than assuming a universal answer.
Why does renting sometimes come out ahead in this calculator?
When the monthly cost of owning (mortgage, tax, maintenance) is substantially higher than comparable rent, a renter can invest that difference plus the down payment, and this invested amount can compound to outpace the equity gained from paying down a mortgage and home appreciation.
Does this calculator include closing costs or selling costs?
No — land transfer tax, legal fees, CMHC insurance (if applicable), and realtor commissions on a future sale aren't modeled, all of which would shift the comparison somewhat further toward renting if included.
Does this calculator account for rent increasing over time?
No — it assumes a constant monthly rent throughout the comparison period, which is a simplification. Real rent typically rises over time, which would somewhat favour buying more than this calculator's projection suggests.
What investment return should I use for the renting scenario?
This should reflect what you'd realistically invest in and expect to earn — a diversified stock portfolio has historically averaged higher long-term returns than more conservative options, but with more year-to-year variability. Use an assumption that matches your actual investment approach.
How much does the comparison period matter?
Significantly — a longer period generally gives mortgage paydown and appreciation more time to compound in favour of buying, while a shorter period is more sensitive to upfront costs and short-term market conditions.
Does this calculator account for CMHC insurance if my down payment is under 20%?
No — it doesn't automatically add mortgage default insurance costs. If your down payment is under 20%, use the CMHC Insurance Cost Calculator separately and factor that premium into your down payment or ongoing costs manually.
What if I don't know what home appreciation or investment returns to expect?
Use conservative, historically grounded assumptions and test a few different scenarios — this calculator is most useful for understanding sensitivity to these assumptions, not for predicting a single certain outcome.
Does buying build wealth even if renting comes out ahead in dollar terms?
Home equity is a form of forced savings that many people find easier to maintain than voluntary investing — while this calculator compares pure dollar outcomes, the behavioural aspect of mortgage paydown is a real, separate consideration for many buyers.
Should I use my current rent or a comparable rent for a similar property?
Use the rent for a property genuinely comparable to the home you're considering buying — comparing a smaller rental to a larger home purchase isn't an apples-to-apples comparison.
Does this apply the same way in every Canadian city?
The mechanics apply everywhere, but the actual inputs (home prices, comparable rents, appreciation expectations) vary enormously by city — always use figures specific to your actual market rather than a national average.
Can I share this rent vs buy comparison as an image?
Yes — tap Share and, on supported devices, your result is shared as a branded image card, not just a text link.
