Rent vs Buy Calculator (Canada)

Renting looks simple — rent, tenant insurance, utilities — and the money spent is gone. Owning is more complex: mortgage interest, property tax, home insurance, maintenance, condo fees, and the opportunity cost of the down payment sitting in the house instead of the market.

Only the principal portion of a mortgage payment builds wealth. In year one of a 25-year mortgage at 5%, roughly 30% of the payment is principal, so the true cost of owning that year is closer to the rent figure than most buyers expect.

• Maintenance runs about 1% of the home's value annually over the long run
• Property tax varies widely — under 0.3% in Vancouver, over 1% in parts of Ontario
• Condo fees replace some maintenance but add special assessment risk
• The down payment's foregone investment return is a real cost of owning

Break-even is the point where cumulative ownership cost, net of equity built and appreciation, falls below cumulative rent. Land transfer tax, legal fees, and eventually realtor commission of 4% to 6% mean owning starts deep in the hole. In most Canadian markets it takes four to seven years to climb out.

The variable that moves it most is appreciation, and that is the one nobody can forecast. Running the comparison at 0%, 2% and 4% annual appreciation shows how much of the case for buying depends on the market rather than the math.

Owning gives payment stability against rising rents, freedom to renovate, and a principal residence exemption that makes the eventual gain tax-free. Renting gives mobility, no exposure to a special assessment or a roof failure, and liquid savings.

In BC, rent increases on an existing tenancy are capped annually, so a long-term renter in place may face far less rent inflation than a market-rate comparison assumes. Someone likely to move cities within three years is usually better off renting regardless of what the spreadsheet says.

The instinct to compare rent against the mortgage payment is misleading in both directions. A big chunk of the mortgage payment is principal, which is forced savings rather than an expense. But ownership also carries costs a renter never sees: property tax, maintenance, insurance, and the transaction costs of buying and eventually selling.

The correct comparison sums the unrecoverable costs on each side over the same holding period, then credits the renter with the investment return on the capital they did not tie up in a down payment.

Buying costs roughly 1.5–3% of the price in land transfer tax, legal fees, and inspection. Selling costs another 4–5% in real estate commission and legal fees. That is 5–8% round trip, which on a $800,000 home is $40,000 to $64,000.

At typical appreciation of 3% a year, it takes two to three years of price growth just to recover the transaction costs — before any of the ongoing carrying costs are considered. This is why almost every rent-vs-buy analysis says renting wins under five years.

Small changes in assumptions swing the result significantly.

• Holding period — the single biggest factor. Under five years favours renting; over ten years usually favours buying.
• Appreciation rate — the difference between 2% and 4% annual growth compounds enormously over a decade.
• The rent you would actually pay — an unusually cheap rental changes the maths completely.
• Investment return on the down payment — a renter investing the difference at 6% is a serious competitor to a homeowner.
• Maintenance — owners consistently underestimate this. One percent of the home's value per year is realistic.
