Rent vs. Buy Calculator
Result
"Stop throwing money away on rent" is one of the most common pieces of financial advice — and one of the most oversimplified. The real rent-vs-buy decision depends on six or seven variables that interact in unintuitive ways, including how long you'll stay, how much you'd earn on the down payment kept invested, the maintenance and tax costs of ownership, and how the local housing market is performing. This calculator pulls those variables together so you can see whether buying actually wins on the math for your specific situation, or whether renting is the smarter financial move.
The math behind the result
You enter the parameters for both sides of the comparison:
- Home price. The purchase price of the home you'd buy.
- Down payment. The cash you'd put down at closing.
- Mortgage rate and term. The interest rate (currently around 6-7% for 30-year fixed) and length of the loan in years.
- Property tax rate. Annual property tax as a percentage of home value, typically 0.5% to 2.5% depending on state.
- Maintenance rate. Annual maintenance costs as a percentage of home value (the standard estimate is 1% per year, sometimes higher for older homes).
- Homeowners insurance. Annual premium for the home insurance policy.
- HOA fees. Monthly homeowners association fees if applicable.
- Rent. The monthly rent for an equivalent place to live.
- Rent growth rate. Expected annual rent increases (typically 2-4%).
- Investment return. Realistic annual return you'd earn on the down payment if kept invested instead (often estimated at 6-7% for a diversified stock portfolio).
- Years staying. How long you plan to stay in the home — this is one of the most important variables.
The calculator runs both scenarios over the time horizon you select, then compares the total dollars out the door in each case — accounting for home appreciation on the buying side and the opportunity cost of the down payment on the renting side.
What your result actually tells you
The most important output is the breakeven year — the year buying starts to financially beat renting over your time horizon. If your planned stay is shorter than the breakeven year, renting wins on the math; if longer, buying wins.
You'll also see the total cost of each path over your time horizon. The dollar gap shows how meaningfully one option beats the other. In some markets the difference is small enough that other factors (flexibility, life stage, peace of mind) should drive the decision. In others, the gap is large enough that the financial answer is clear.
Two things to notice:
- Buying often wins eventually, but the breakeven can be 5 to 10+ years out. If you plan to stay shorter, the math typically favors renting.
- The "rent" cost includes the investment return on your down payment. This is often missing from rent-vs-buy analyses online and significantly tilts the math.
Why "rent is throwing money away" is wrong
The phrase implies that every dollar spent on rent is wasted while every dollar spent on a mortgage builds equity. The actual math is messier:
On a $400,000 mortgage at 7% APR for 30 years, the monthly principal-and-interest payment is roughly $2,660. In year one, about $2,330 of each payment goes to interest, and only about $330 builds equity. Over the first 5 years, you'd pay roughly $160,000 in total payments but build only about $25,000 in equity.
The other $135,000 went to interest, property taxes, insurance, maintenance, HOA fees — none of which builds equity. Add a 6% transaction cost when you sell (realtor commission, closing costs, transfer taxes), and the equity built in early years can be entirely consumed by the cost of leaving.
Renting has costs you don't get back. So does buying. The real question isn't "which one has costs?" — both do — but "which one has lower total costs after factoring in everything?"
The 5-year rule (and when it breaks)
A common rule of thumb says buying beats renting if you'll stay at least 5 years. The logic: 5 years is roughly long enough for home appreciation and equity buildup to offset the transaction costs of buying and selling (which together total 8-10% of the home's value).
The rule works as a starting point but breaks in several situations:
- High mortgage rates. At 7%+ rates, the interest paid in early years is so high that the breakeven stretches to 7-10 years in many markets.
- Slow-appreciation markets. If homes in your area haven't appreciated meaningfully in years, the math swings hard toward renting.
- High HOA or property tax areas. These costs don't build equity and can push breakeven far out.
- You're stretched at the down payment. If buying drains your emergency fund or forces you to skip retirement contributions, the opportunity cost grows substantially.
Test your specific numbers in the calculator — the 5-year rule is a generalization, not a universal truth.
When to rent (even if you can afford to buy)
Several situations make renting the better choice on its own merits, separate from the math:
- You might move within 3-5 years. Job uncertainty, possible relocation, career changes, or relationship transitions all raise the probability you won't stay long enough to make ownership pay off.
- You don't want to be responsible for maintenance. Owning means furnaces, roofs, plumbing, appliances, and surprise repairs are all your problem. Renting outsources that to a landlord.
- You haven't saved a full emergency fund. First-year homeownership often delivers $5,000-$15,000 in surprise costs. If a single appliance failure would create financial stress, you're not ready to buy.
- Rent is significantly below the price-to-rent ratio for the area. If the equivalent home would rent for far less than the monthly cost of buying, the math favors renting almost regardless of time horizon.
- You'd be using a 3-5% down payment. Low down payments mean PMI, higher interest, and being underwater for longer if home values dip — all of which make renting relatively more attractive.
When to buy (even if the math is close)
Some non-financial factors tilt the decision toward buying even when the spreadsheet is roughly even:
- You want to lock in housing costs. A fixed-rate mortgage caps your principal-and-interest forever. Rent goes up 2-5% per year, sometimes more. Over 30 years that compounds dramatically.
- You're settling in a specific area for the long term. Kids in school, family nearby, career anchored locally — the longer your time horizon, the more buying wins.
- You want to customize the space. Owning means painting walls, replacing fixtures, doing renovations — things renters generally can't.
- You're disciplined enough to treat the mortgage payment as forced savings. A meaningful portion of homeowner wealth-building comes from the fact that the mortgage forces equity accumulation. If you'd otherwise spend the rent-savings rather than invest it, the comparison shifts toward buying.
Where this estimate can be off
The calculator assumes several things that real markets often don't deliver cleanly:
- Constant appreciation rate. Home values don't grow at a steady percentage every year. They surge in some periods, stall or fall in others. Use a conservative long-run estimate (2-3% for slow markets, 3-4% for average, 4-5% for hot markets).
- Constant rent growth. Rent doesn't increase smoothly either — rent control, oversupply, and local economic shifts all create volatility.
- Constant investment return. Stock market returns vary substantially year to year. The 6-7% long-run average assumes a 20-30 year horizon; shorter periods can see negative returns.
- No tax deductions modeled. Mortgage interest and property tax deductions exist for itemizers (typically only useful at higher home prices/incomes after the 2017 tax law changes).
- Doesn't include closing costs to sell. If your time horizon ends with selling the home, factor in 6-8% in selling costs on top of the analysis.
Questions readers ask
Is it always cheaper to buy than rent long-term?
No. Whether buying beats renting depends on how long you stay, how much homes appreciate in your area, your mortgage rate, property taxes, maintenance costs, and the opportunity cost of your down payment. In high-cost markets with low appreciation, renting can be cheaper for years. The common "5-year rule" suggests buying beats renting if you'll stay at least 5 years, but the actual breakeven varies by location and market conditions.
What is the rent-vs-buy breakeven point?
The breakeven point is the number of years you'd need to own a home before the total cost of buying becomes less than renting. It accounts for the down payment, closing costs, monthly mortgage, property taxes, maintenance, insurance, HOA, and home appreciation — versus the rent you'd otherwise pay and the investment return you'd earn on the down payment if you kept it invested instead. In many markets, breakeven is 5 to 8 years.
Is rent really "throwing money away"?
Not in the way the saying implies. Buyers pay property taxes, mortgage interest, maintenance, insurance, and HOA fees that build no equity — that's also money you don't get back. In the early years of a mortgage, most of the payment is interest (not principal), so very little builds equity. Rent buys flexibility, predictable costs, and no maintenance responsibility — which has real financial value in many situations.
Should I rent if I plan to move within 3 years?
Almost certainly yes. The transaction costs of buying and selling a home — typically 8 to 10 percent of the home value combined — are very hard to recover in a 3-year window unless the local market is appreciating rapidly. If you're not confident you'll stay at least 5 years, renting is usually the safer financial choice even if the monthly rent looks higher than the equivalent mortgage payment.
How does home appreciation affect the rent-vs-buy decision?
Significantly. Historical US home appreciation averages 3 to 4 percent per year nominally, though it varies widely by market and decade. Modest appreciation can tip the math toward buying because the home's value grows on the full purchase price, not just on your down payment. In flat or declining markets, the rent-vs-buy math swings hard toward renting because you're paying carrying costs on an asset that isn't gaining value.
Should I include opportunity cost of the down payment?
Yes — this is often the most overlooked factor. A $60,000 down payment invested in a diversified index fund could realistically grow at 6 to 8 percent annually over a long horizon. Over 10 years, that's $107,000 to $130,000. If buying a home, you're locking that capital in real estate instead. A proper rent-vs-buy analysis compares total cost of ownership against rent PLUS the investment return you'd earn on the down payment kept invested.
