Why "rent is throwing money away" is wrong
The instinct that renting wastes money while buying builds wealth is only half true. Buying does build equity — but it also carries big costs renters never pay: closing costs, property tax, insurance, maintenance, and the opportunity cost of locking a large down payment into a house instead of investing it. A fair comparison has to weigh all of these over the years you'll actually stay. This calculator does exactly that and reports the net cost of each path.
What goes into each side
Buying totals your down payment and closing costs, every mortgage payment during your stay, and ongoing tax/insurance/maintenance — then subtracts the equity you recover when you sell (the appreciated home value, minus selling costs and any remaining loan). Renting totals your rent over the same years (growing each year), then subtracts the investment gains you'd earn by putting the down payment you didn't spend into the market instead. Whichever ends with the lower net cost wins.
The break-even horizon
The single biggest factor is how long you stay. Buying has large upfront and exit costs (closing plus ~6% selling costs), so over a short stay those fixed costs dominate and renting usually wins. The longer you stay, the more those one-time costs spread out and the more equity and appreciation accumulate — tilting the math toward buying. Most buyers need roughly five years or more in the home for buying to pay off, though it depends heavily on your local rent-to-price ratio, appreciation and rates. Try dropping "years you'll stay" to 3 and raising it to 10 to see the answer flip.
The assumptions that swing the result
- Appreciation. Higher home appreciation favors buying; flat or falling prices favor renting. Don't assume boom-era numbers — 2–4% a year is a sober long-run figure.
- Investment return. This is the renter's secret weapon: a down payment invested at 5–7% is real money working for you. The higher this rate, the better renting looks.
- Rent growth vs ownership costs. Fast-rising rents punish renters; high property taxes and maintenance punish owners.
Beyond the numbers
Money isn't the whole story. Buying offers stability, control, and a forced-savings discipline; renting offers flexibility, no maintenance risk, and mobility for your career. If the costs are close, those lifestyle factors should decide. But run the numbers first — pair this with our renting vs buying guide, the home affordability calculator, and the mortgage calculator to see the full picture.
