Rent vs Buy Calculator

The rent vs buy calculator compares the total financial outcome of buying a home versus renting an equivalent property and investing the cost difference. This is one of the most important financial decisions Canadians face, and the answer depends heavily on your specific numbers — local real estate prices, mortgage rates, rental costs, and investment returns.

How this rent vs buy calculator works

Buying scenario inputs:

• Home price, down payment percentage, and mortgage rate
• Property tax, home insurance, and maintenance costs
• Expected home appreciation rate

Renting scenario inputs:

• Monthly rent and expected annual rent increases
• Investment return on the money saved by not buying

The calculator projects both scenarios over your chosen time horizon and shows which option leaves you with more wealth, accounting for equity built through home ownership versus investment growth from renting.

Key factors that determine the outcome

Factors that favor buying

• Low mortgage rates — Lower carrying costs make ownership more affordable
• High home appreciation — Property values growing faster than investment returns
• Long time horizon — More time to recoup upfront costs and build equity
• High rent — When rent is expensive relative to house prices
• Disciplined spending — The forced savings aspect of mortgage payments

Factors that favor renting

• High home prices — When the price-to-rent ratio exceeds 20-25×
• Short time horizon — Buying costs (land transfer tax, legal fees, CMHC) need years to recover
• High mortgage rates — More of your payment goes to interest rather than equity
• Strong investment returns — When markets outperform real estate
• Low rent — Especially in rent-controlled units

The price-to-rent ratio

The price-to-rent ratio helps gauge whether buying or renting is a better deal in a specific market:

Formula: Home Price ÷ (Monthly Rent × 12)

Canadian examples (2026):

Toronto and Vancouver’s ratios above 35 suggest renting and investing is financially competitive. Markets under 25 increasingly favor buying.

The hidden costs of buying

Many first-time buyers underestimate the full cost of home ownership:

On a $600,000 home, these costs add $10,000-$15,000 upfront and $10,000-$15,000 per year in ongoing carrying costs beyond the mortgage payment.

The renting + investing strategy

The renting strategy works best when:

1. You invest the down payment you would have used (in a TFSA or RRSP)
2. You invest the monthly difference between renting and owning
3. You maintain investment discipline (automatic contributions)
4. You choose low-cost index funds for consistent long-term growth

Example: Instead of a $100,000 down payment on a $500,000 home, you invest $100,000 and save $800/month (the difference between rent and total ownership costs). At 7% annual return over 20 years, your portfolio grows to approximately $755,000 — potentially more than the home equity gained through buying.

When to buy in Canada

Despite the numbers sometimes favoring renting, buying makes sense when:

• You plan to stay in the same city for 7+ years
• You want the stability and control of home ownership
• Your mortgage payments are similar to equivalent rent
• You have a solid emergency fund and no high-interest debt
• You qualify for a comfortable mortgage without stretching your debt ratios

Tax advantages of home ownership in Canada

Canada offers several tax benefits that tilt the comparison toward buying:

Principal residence exemption — When you sell your primary home, the entire capital gain is tax-free. On a $200,000 gain, this saves $25,000–$50,000+ in capital gains tax depending on your tax bracket. No other investment in Canada offers this level of tax-free growth.

First Home Savings Account (FHSA) — Contributions are tax-deductible (like an RRSP) and withdrawals for a home purchase are tax-free (like a TFSA). You can save up to $40,000 in an FHSA and invest it while saving for your down payment.

Home Buyers’ Plan (HBP) — Withdraw up to $60,000 from your RRSP tax-free for your first home purchase. Repayment over 15 years.

GST/HST New Housing Rebate — Partial rebate on the GST/HST paid on a new home priced under $450,000.

Renters don’t have an equivalent tax shelter — investment gains in non-registered accounts are taxable, and TFSA/RRSP room is limited.

Rent control: what renters should know

Several provinces have rent control that protects tenants from large increases:

Provinces without rent control (Alberta, Saskatchewan, New Brunswick, Nova Scotia, Newfoundland) allow landlords to raise rent by any amount with proper notice. In these markets, long-term rent costs are harder to predict, which can make buying more attractive.

The 5% rule: a quick rent-vs-buy shortcut

A popular rule of thumb: multiply the home’s value by 5%, then divide by 12 to get the monthly “break-even” rent. If you can rent for less than this number, renting is likely the better financial choice.

Example: $600,000 home × 5% = $30,000 ÷ 12 = $2,500/month. If equivalent rent is under $2,500, renting wins. If rent is higher, buying wins.

The 5% accounts for the three major unrecoverable costs of owning:

• ~1% property tax
• ~1% maintenance
• ~3% cost of capital (mortgage interest + opportunity cost of down payment)

This rule is a starting point — use the calculator above for a precise comparison with your actual numbers.
