Rent vs Buy: Which Is Better for Your Money?

Two numbers sit on the kitchen table: the rent and the mortgage payment. The rent is $2,200. The payment on the house next door is $2,800. Most people pick the lower monthly number and stop there.

The decision has a third number: time. How long you will live in the place decides which side wins, because buying front-loads costs that renting never sees. This guide gives you a fast filter, the full cost picture, and the breakeven math — then points you to a calculator that runs your own numbers.

The 5% rule: a fast filter, not a verdict

The 5% rule asks one question: is the annual rent below about 5% of the home's price? When it is, renting usually beats buying on cash flow in the early years.

Take a $400,000 home. Five percent of the price is $20,000 a year — about $1,667 a month. If the same place rents for $2,200, the rent sits above the threshold, which means buying may come out ahead once you hold the home long enough. Flip the rent below $1,667 and the answer flips with it.

The rule is a filter, not a verdict. It ignores your timeline, your down payment, and local tax rates. Use it to sort quickly, then do the real math below.

The threshold sits near 5% for a reason. Ownership carries recurring costs the listing never shows — property tax, insurance, and maintenance together commonly run 2-3% of value a year — and buying pays transaction costs up front. When rent sits near 5% of price, the two paths start near parity, and the deciding variable becomes time in the home.

The buy side has costs the listing never shows

The listing shows the price and the payment. It does not show the rest of the bill:

The mortgage payment is only one line of this table. The mortgage payment breakdown article shows how principal, interest, taxes, and insurance combine into the real payment — and the renters insurance guide covers the policy you need on whichever side of the decision you land.

There is also the payment itself. On a $400,000 loan at 6.7%, principal and interest run about $2,581 a month, and the first payment moves only about $348 to principal — the rest is interest. For the first several years, buying's monthly "savings" is a slow build, not a bank deposit. The loan amortization guide shows how that split flips over time.

The $400,000 example, run both ways

In year one, buying loses on cash. Every dollar of principal is wealth you keep, but the gap has to close over time. The mortgage payment calculator turns the payment side of this table into your exact numbers.

The comparison gets fairer in year five. The mortgage payment is fixed, while market rents have a habit of moving up, and every dollar of principal paid is a dollar you keep. But the same table shows the risk: if you leave in year three, the closing costs and a sales commission come out of the equity you just built. The breakeven is the moment the kept dollars finally cover the front-loaded ones.

Breakeven usually lands in years 5 to 10

Buying becomes cheaper when the costs you keep — principal paydown and a fixed payment — outweigh the costs you lose to rent increases and a growing balance. Industry estimates commonly put the breakeven at 5 to 10 years for typical markets.

That is an estimate, not a law. Fast rent growth and rising home values pull the breakeven earlier. Flat prices and heavy maintenance push it later. If you expect to move in three years, renting usually wins; the transaction costs alone are a wall.

Two mini-scenarios show the range. In a city where rents grow steadily while prices stay flat, the breakeven can arrive early — the fixed payment eventually catches the rising rent. In a market where prices are flat and property taxes creep up, the breakeven can stretch past a decade. Neither scenario is a prediction; both are why the breakeven belongs in your own math, not in a headline.

When buying wins sooner than you expect

• Your rent is growing faster than the market's prices.
• You stay long enough for appreciation and principal paydown to cover the closing costs.
• The 5% rule already favors buying, so cash flow is not working against you.

The paying off your mortgage early guide is the natural next question once you own: whether to accelerate the mortgage or invest the surplus.

When renting is the better call

• Your horizon is under five years.
• Your job, family, or location plans are uncertain.
• Rent sits below the 5% threshold, so renting wins on cash flow.
• The down payment would drain your emergency fund — the emergency fund guide explains why that is the more urgent problem.

Turn the decision into your own numbers

Plug your price, rent, and rate into the rent vs buy calculator. It compares the monthly picture and shows how many years you need to stay for buying to win. Then browse the housing and moving hub for the rest of the calculators in this family — affordability, equity, refinancing, and moving costs all feed the same decision.

Four steps make the decision concrete: run the calculator with your actual rent, price, and rate; add the buy-side costs from the table above; write down your realistic horizon in the home; and compare the breakeven month against that horizon. If the breakeven lands inside your stay, buying has a real case. If it lands after you expect to leave, the lease is the better contract.
