About Rent vs Buy Calculator

Free rent vs buy calculator. Compare the true cost of renting versus buying a home over any time horizon. Factor in appreciation, taxes, and opportunity cost.

How to use

  1. Enter your current monthly rent and the purchase price of a comparable home you are considering. Use a home with similar size, location, and features for an accurate comparison. The goal is to compare equivalent housing situations, not a 1-bedroom rental versus a 4-bedroom house.
  2. Input your available down payment, mortgage interest rate, and the time horizon you plan to stay. The time horizon is critical — buying almost always wins over 10+ years but frequently loses over 1-3 years because closing costs, agent commissions, and transaction taxes eat into any equity built.
  3. Add the true costs of ownership: property taxes (0.5-2.5% of value annually depending on municipality), home insurance ($1,000-$2,500/year), maintenance (budget 1-2% of home value per year), and closing costs for both purchase and eventual sale.
  4. Set your assumptions for annual home appreciation (historical Canadian average: 3-5%), annual rent increases (typically 2-4% in most markets, though some provinces have rent control), and investment return rate for the alternative scenario where you invest the down payment instead of buying.
  5. Compare total wealth outcomes side by side. The calculator accounts for equity buildup, appreciation, tax benefits, opportunity cost of the down payment, transaction costs, and the time value of money. The result shows your net financial position under both scenarios at the end of your time horizon.
  6. Adjust assumptions to stress-test the decision. What if appreciation is 2% instead of 5%? What if interest rates rise at renewal? What if you need to move in 3 years instead of 7? A robust buy decision should still make sense under moderately pessimistic assumptions.

Frequently asked questions

Is it cheaper to rent or buy in Canada?
It depends on your specific market, time horizon, and financial situation. In expensive cities like Toronto and Vancouver, renting is often financially better for stays under 5-7 years because property prices are so high relative to rents. In more affordable markets like Edmonton, Winnipeg, or Halifax, buying can break even within 2-3 years. Key factors: if monthly ownership costs (mortgage + taxes + insurance + maintenance) significantly exceed rent, the difference invested may grow faster than home equity. If ownership costs are similar to rent, buying usually wins because you build equity instead of paying a landlord.
When does buying break even versus renting?
The break-even point is when the total cost of buying (down payment opportunity cost, closing costs, mortgage interest, taxes, insurance, maintenance) equals the total cost of renting (rent payments, renters insurance) adjusted for equity buildup and appreciation. In most Canadian markets, this break-even occurs at 4-7 years. In expensive markets like Toronto, it can be 7-10+ years. Factors that shorten the break-even: lower purchase prices relative to rent, higher appreciation, lower interest rates. Factors that lengthen it: high closing costs (especially land transfer tax), high property taxes, low appreciation expectations.
What is opportunity cost in rent vs buy analysis?
Opportunity cost represents the investment returns you forgo by tying up your down payment in a home instead of investing it in financial markets. A $100,000 down payment invested at 7% annually would grow to approximately $197,000 in 10 years. As a home down payment, that money earns the home's appreciation rate (historically 3-5% in Canada) but also unlocks leverage — you control a $500,000 asset with $100,000 invested. The comparison is not straightforward because homes provide leverage that stocks typically do not. This calculator accounts for opportunity cost in both scenarios. Use the Compound Interest Calculator to model exactly how your down payment would grow under different investment scenarios.
Does the 5% rule work for rent vs buy?
The 5% rule is a rough heuristic: multiply the home value by 5%, divide by 12 to get a monthly breakeven rent. If your rent is lower than this number, renting may be better financially. On a $500,000 home: $500,000 x 5% / 12 = $2,083/month breakeven rent. If you can rent a comparable place for $1,800/month, renting likely wins. The 5% accounts for approximately 1% property tax, 1% maintenance, and 3% cost of capital (mortgage interest or investment opportunity cost). This is a screening tool only — run the full calculator for an accurate comparison with your specific numbers.
Should I factor in tax benefits?
Yes, but the tax implications differ between countries. In Canada, your primary residence is exempt from capital gains tax when you sell, which is a significant benefit for long-term homeowners — $200,000 in appreciation is completely tax-free. However, mortgage interest is NOT tax-deductible for Canadian homeowners (unlike the US). In the US, mortgage interest and property taxes may be deductible if you itemize. Rental expenses are deductible against rental income in both countries. The Canadian principal residence exemption makes buying more attractive for long-term holds, while the US mortgage interest deduction reduces the effective cost of ownership.
What non-financial factors should I consider?
Financial calculations only tell part of the story. Buying provides stability (no landlord raising rent or selling), freedom to renovate and customize, pride of ownership, and forced savings through equity buildup. Renting provides flexibility to move for career opportunities, no maintenance responsibilities, lower financial risk (no exposure to property value declines), and the ability to live in a more expensive neighborhood than you could afford to buy in. If your career requires mobility, or you are unsure about staying in a city for 5+ years, the flexibility value of renting may outweigh the financial benefit of buying.
How do interest rate changes affect the rent vs buy decision?
Interest rates significantly shift the calculus. At 3% mortgage rates (early 2021), buying was favorable in most markets because monthly payments were low relative to rents. At 6% rates (2023-2024), the same property costs 40-50% more per month, making renting more attractive in many cities. In Canada, most mortgages renew every 5 years, creating renewal risk — if you lock in at 5% today but rates are 7% at renewal, your payment increases significantly. The calculator lets you model different rate scenarios to see how sensitive the rent vs buy decision is to rate changes in your specific situation.
