How to Use This Calculator
Tab "Rent vs Buy"
Enter the purchase price, comparable monthly rent, down payment %, mortgage rate, and province. The calculator computes net wealth for both scenarios over your chosen time horizon. Buying wealth = home equity (appreciated value minus remaining mortgage). Renting wealth = invested savings (down payment + monthly cost difference compounded at your chosen investment return). It shows which option wins and the break-even year.
Tab "Cash Flow"
See the monthly outflow for buying (mortgage + property tax + insurance + maintenance + strata) versus renting (rent + renter's insurance). The year-by-year table shows cumulative costs, equity built, and the renter's investment balance growing over time. This helps you understand the ongoing cash flow impact of each choice.
Tab "Sensitivity"
Choose a variable to test โ property appreciation, rent growth, mortgage rate, or investment return โ and see how 3 scenarios (pessimistic, base, optimistic) change the outcome. This reveals which assumptions matter most for your decision.
The Formula
Effective monthly rate = (1 + annual rate / 2)^(1/6) - 1
Monthly payment = P ร r ร (1+r)^n / ((1+r)^n - 1)
CMHC mortgage insurance (if down payment < 20%):
5-9.99% down โ 4.0% premium | 10-14.99% โ 3.1% | 15-19.99% โ 2.8%
Premium is added to the mortgage principal (max purchase price $1.5M)
Net wealth comparison:
Buy net wealth = Home value ร (1 + appreciation)^n - Mortgage balance
Rent net wealth = Invested savings (down payment + LTT + monthly surplus) compounded at investment return
Break-even: The year when buy net wealth first exceeds rent net wealth.
Land transfer tax: Province-specific marginal rates (ON, BC, QC) or flat approximation (AB, others).
The renter invests the entire down payment and closing costs upfront, plus any monthly savings versus the buyer's total outflow. Property tax and maintenance scale with home value over time.
Example
Toronto Condo โ $800K vs $2,500/mo Rent
A first-time buyer considering an $800,000 condo in Toronto with 20% down, versus continuing to rent at $2,500/month.
The renter saves roughly $2,883/month and invests the $160,000 down payment plus $12,475 LTT upfront. At 6% investment return and 3% appreciation, buying typically breaks even around year 8-12 depending on rent growth. Over 15+ years, buying usually wins as equity accumulates and rent keeps rising.
