Compare the true long-term cost of renting versus buying a home, including mortgage payments, taxes, maintenance, appreciation, and investment opportunity cost. Find your break-even year instantly.
The rent-versus-buy decision is one of the largest financial choices most people make, yet it's frequently decided using rules of thumb ('rent is throwing money away,' 'buy as soon as you can') that don't hold up once you actually run the numbers. The true cost of buying includes far more than the mortgage payment — property taxes, insurance, maintenance, and transaction costs when buying and selling all matter — while the true cost of renting has to account for what a renter could do with the money they didn't spend on a down payment.
This calculator uses a net-worth comparison model: it tracks what a buyer's wealth would look like (home equity plus any leftover savings, invested) against what a renter's wealth would look like (their invested down payment plus any monthly savings from paying less in rent than an owner would pay in housing costs) over your chosen time horizon. Whichever scenario leaves you with more net worth at the end is the financially better choice — for your specific numbers, not a generic rule.
The single most important factor in this decision is usually how long you plan to stay. Buying involves significant upfront costs (closing costs, and eventually selling costs) that only pay off over time as you build equity and avoid rising rent. The calculator's break-even year tells you exactly how long you'd need to stay for buying to become the better financial choice given your specific home price, rent, and rate assumptions.
A couple is deciding between buying a $450,000 home with 20% down at a 6.5% mortgage rate over 30 years, or renting a comparable home for $2,400/month. They plan to stay for 7 years. The calculator shows their monthly mortgage payment (around $2,275 before tax, insurance, and maintenance), a break-even year of roughly year 5, and that — if they stay the full 7 years as planned — buying leaves them with meaningfully more net worth than renting and investing the difference, mainly due to home equity built through appreciation and principal paydown.
The single most important output is the break-even year compared against how long you actually plan to stay. If your planned stay is well beyond the break-even year, buying is likely the stronger financial choice under the assumptions used. If you plan to stay for a much shorter time than the break-even year, renting is likely better, even if buying 'feels' like the more responsible adult decision. The net advantage figure tells you the size of the difference, not just the direction. A small net advantage in either direction means the decision is close and could easily be swayed by factors this calculator doesn't capture — job stability, family plans, or how much you value the flexibility of renting versus the permanence of owning. Remember that this model relies on assumptions (property tax rate, investment returns, appreciation rate) that are reasonable long-run averages but may not match your specific location or timeline. If you have strong local knowledge that home appreciation in your target neighborhood runs meaningfully above or below the national average, mentally adjust the results accordingly.
Deciding whether to rent or buy a home is one of the most consequential financial decisions most adults make, and it's a decision that popular wisdom often oversimplifies. 'Renting is throwing money away' ignores that mortgage interest, property tax, insurance, and maintenance are also money spent without building equity. 'You should always buy if you can afford it' ignores transaction costs, opportunity cost, and how dramatically the right answer depends on how long you'll actually stay in the home. A rigorous comparison has to look beyond the sticker price of a mortgage payment versus a rent check. It needs to account for the full cost of ownership — taxes, insurance, upkeep — against the full cost of renting, while also crediting each side for what happens to money that isn't spent. A renter who doesn't pay a down payment can invest that money; a buyer who pays less monthly than a renter in some periods (as rent rises past a fixed mortgage payment) can invest that difference too. Tracking both sides honestly, over your actual expected time horizon, is what separates a real answer from a rule of thumb. The result of this kind of analysis is often a specific 'break-even' year — the point at which staying and building equity overtakes the flexibility and lower upfront cost of renting. For people who move every 2-3 years, renting frequently wins financially. For people who stay 10+ years in one home, buying usually wins by a wide margin. The years in between are where a personalized calculation, using your actual numbers, matters most.
Use the Rent vs Buy Calculator whenever you're weighing a specific home purchase against continuing to rent — when house-hunting and comparing a listing's price to your current rent, when deciding whether to buy in a new city you're relocating to, when trying to determine how many years you'd need to stay for a purchase to make financial sense, or when rising rent in your area has you reconsidering whether buying now makes more sense than it used to. It's especially useful for testing multiple scenarios: different down payment sizes, different mortgage rates you might qualify for, or different assumptions about how long you'll stay.
