Compare your long-term net worth whether you rent and invest, or buy a home. Based on real Canadian mortgage rules.
The calculator runs a year-by-year simulation comparing two financial paths: buying a home and building equity, versus renting and investing the equivalent capital.
Each year: Home Value − Remaining Mortgage Balance − Selling Costs (4%). The home value grows at your chosen appreciation rate. The mortgage balance decreases as you pay principal each month using Canadian semi-annual compounding.
The renter invests their down payment at your chosen investment return rate. Each month, if the total buying cost (mortgage + property tax + maintenance) exceeds the rent, the renter invests that difference too. This is the core of the opportunity cost comparison.
Canadian mortgages compound semi-annually (twice per year), unlike US mortgages which compound monthly. The effective monthly rate used is:
Effective monthly rate = (1 + annual rate / 2)^(1/6) − 1
Owning a home ties up capital (your down payment) that could otherwise be invested. The calculator quantifies this trade-off. If a renter invests their down payment and monthly surplus into a diversified portfolio, they may accumulate comparable or greater net worth — depending on appreciation rates, investment returns, and time horizon.
Buying: $650,000 home, $130,000 down payment (20%), 5.5% mortgage rate, 25-year amortization, 3.5% appreciation, 1% property tax, 1% maintenance.
Renting: $2,200/month rent, 3% annual increase, 6% investment return.
After 10 years: The buyer's home would be worth approximately $919,000 with a remaining mortgage balance around $395,000, yielding roughly $488,000 in net worth after selling costs. The renter's $130,000 down payment invested at 6% grows to ~$232,000, plus monthly surplus investment contributions — typically resulting in renting winning in the first 5–7 years, with buying taking over around year 8–10 in this scenario.
