Should You Rent or Buy? The Complete Financial Analysis
The rent vs. buy decision is the largest financial choice most people make — yet it's routinely oversimplified to "renting is throwing money away." That's wrong. Whether buying is financially superior to renting depends entirely on local market conditions, how long you plan to stay, your down payment, mortgage rate, and what you'd do with the capital tied up in a home if you rented instead.
This calculator runs the complete comparison: total cost of ownership (mortgage interest, property tax, insurance, maintenance, opportunity cost of down payment) vs. total cost of renting (rent payments, renters insurance, invested down payment returns). The break-even year is when buying finally beats renting in cumulative net worth terms.
The Costs Most People Forget When Buying
Opportunity cost of the down payment: A $100,000 down payment invested in a diversified index fund at 7% grows to $197,000 in 10 years. That's the real cost of tying up capital in a home — and it's rarely factored into the "build equity" argument.
Maintenance and repairs: The standard rule of thumb is 1–2% of home value per year. On a $500,000 home, that's $5,000–$10,000 annually — a cost renters never pay.
Transaction costs: Buying and selling a home costs approximately 8–10% of the home's value in realtor commissions, closing costs, and taxes. If you move within 5 years, these costs alone can wipe out all equity gains.
When Buying Clearly Wins
Buying is financially superior when: you plan to stay for 7+ years, your local price-to-rent ratio is below 20 (home price ÷ annual rent), mortgage rates are relatively low, and you have a substantial down payment that keeps your mortgage payment below the equivalent rent. In these conditions, forced savings through equity buildup and property appreciation can significantly outperform renting.
When Renting Clearly Wins
Renting is financially superior when: you might move within 5 years, local price-to-rent ratios exceed 25, you'd invest the down payment and monthly savings difference, or you're in a high-appreciation market where homes are priced for expected future gains rather than current fundamentals. In expensive cities like Toronto, Vancouver, San Francisco and New York, renting and investing the difference has historically outperformed buying in many scenarios.
