Rent vs Buy
Calculator
Compare the true long-term cost of renting versus buying — including opportunity cost on your down payment, home appreciation, equity built, tax deductions, and maintenance. Find your break-even year.
What "net cost" means here
Raw costs (rent paid, mortgage payments) don't tell the full story. Net cost adjusts for what you get back: equity you build, home value appreciation, and — critically for renters — the investment growth on money you didn't tie up in a down payment. A renter who invests their would-be down payment at 7% return builds real wealth too. This calculator accounts for all of it.
The break-even year explained
Buying is expensive upfront — closing costs, down payment, early mortgage interest. Renting is cheaper short-term. The break-even year is when cumulative net cost of buying drops below cumulative net cost of renting. If you plan to stay longer than the break-even year, buying typically wins. If you might move before then, renting is likely better financially.
Opportunity cost: the hidden factor
A 20% down payment on a $450,000 home is $90,000. If that $90,000 were invested in a diversified index fund at 7% annually, it grows to ~$343,000 in 20 years. This is the opportunity cost of the down payment — one of the most underappreciated numbers in the rent vs buy debate. This calculator includes it on the renting side.
When buying almost always wins
Buying tends to win decisively when: (1) you stay 7+ years in an appreciating market, (2) your mortgage payment is close to or below local rents, (3) you're in a high tax bracket and itemize deductions, and (4) you have a stable income and emergency fund. It tends to lose when you move frequently, buy in a flat or declining market, or stretch too far on the purchase price.
