The break-even year is the single most useful number in the rent-vs-buy decision. It tells you exactly how long you need to plan to stay before buying makes financial sense — and what happens to your net worth if you leave before or after that year.
With the default inputs above, the break-even lands at year 7. The buyer's net worth (equity in the appreciated home plus any invested savings) crosses the renter's net worth (their invested down-payment equivalent) at the end of year 7. Stay past year 7 and owning pulls ahead. Sell before it and the renter who invested the down payment likely comes out ahead.
Three variables drive where the crossover lands for your specific numbers.
What drives the break-even year
Transaction costs dominate the early years. Buying costs roughly 3% of the purchase price and selling costs roughly 6% — a combined $36,000 on a $400,000 home that the buyer must recoup through appreciation and equity before the comparison evens out. This is why break-even rarely falls before year 4 or 5, even in favorable markets.
After transaction costs are absorbed, appreciation and rent growth drive the crossover. If home prices appreciate 4% per year and rent grows at 3%, the buyer's equity compounds faster than the renter's investment pot grows. Once the two net-worth lines cross in the chart above, buying has won the comparison for the hold period.
How the What-If chips shift the crossover
The 'Stay 5 years longer' chip is the most powerful lever: extending the horizon from 7 to 12 years typically shifts a close verdict to a decisive buy in most moderate markets, because appreciation and rent growth compound over the additional years.
'Invest 2% better' moves the opposite direction: a higher investment return gives the renter's pot more momentum, pushing the break-even year later — or eliminating it entirely if portfolio growth outpaces equity. This is the crux of the rent-vs-buy debate: leveraged home appreciation versus diversified portfolio returns.
Planning around the break-even year
If your planned stay is within one to two years of the break-even, the financial case for buying is marginal. Job changes, family moves, and relationship changes create real risk that you will sell before the crossover. In those cases, renting preserves optionality at a low financial cost.
If your planned stay is three or more years past the break-even, buying looks substantially more compelling. The cumulative net-worth advantage of owning grows each year past the crossover, and the renter's path to catching up becomes increasingly difficult as equity and rent-payment divergence widens.
Frequently asked questions
How many years does it take for buying to beat renting?
In most U.S. markets at typical conditions — 20% down, 6 to 7% mortgage rate, 3 to 4% home appreciation, 3% rent growth — the break-even year falls between 5 and 10. The defaults in this calculator produce a break-even at year 7. Markets with high transaction costs or low appreciation can push break-even past year 15 or beyond.
What does the 'break-even year' mean exactly?
The first year where the buyer's net worth — home equity plus any invested savings — equals or exceeds the renter's net worth, which is their invested down-payment equivalent plus accumulated monthly savings. Before that year, the renter has more total wealth. After it, the homeowner does.
What pushes the break-even year later?
Later break-even: high price-to-rent ratio, short planned hold, low home appreciation, high investment returns, high closing costs, or high selling costs. Each What-If chip above shows exactly how each factor shifts the crossover year for your specific inputs.
What pushes the break-even year earlier?
Earlier break-even: rapid rent growth (reduces the renter's monthly savings advantage), low mortgage rate, high home appreciation, low selling costs, and a large down payment (no PMI, lower rate). Low investment returns also help the buyer by slowing the renter's competing pot growth.
What if there is no break-even within my horizon?
No break-even within your horizon means the renter's invested pot stays ahead for the entire period you plan to hold. This is common in high price-to-rent markets (above 20), very short horizons (under 5 years), or when investment returns significantly outpace home appreciation. It means renting is the right financial choice for that scenario — not a failure of the model.
Worked examples
Worked example 1
Standard break-even scenario — year 7 crossover
$400,000 home, 20% down, 6.5% rate, $2,000/month rent, 4% appreciation, 5% invest return.
Monthly mortgage
$2,023
Verdict
Near tie
Break-even year
Year 7
Break-even arrives at year 7. The buyer lags behind for the first 6 years as selling costs and interest drag outweigh equity accumulation. At year 7 the accumulated equity and appreciation tip the scales.
Worked example 2
High appreciation — early break-even
Same inputs but 6% annual appreciation (hot market scenario).
Monthly mortgage
$2,023
Verdict
Buying wins
Break-even year
Year 3
At 6% appreciation, break-even arrives at year 3 — 4 years earlier than at the 4% base case. Each 1% of additional annual appreciation shaves roughly 2 years off the crossover. But 6% sustained appreciation is not guaranteed; model the base case at 3–4%.
What affects the result
Selling cost percentage
Selling costs of 6% on a $400k home create a $24,000 immediate drag for the buyer. This is the primary reason break-even takes 6–9 years in most scenarios. Negotiating a lower agent commission or using a discount brokerage can meaningfully shorten break-even.
Home appreciation rate
Each 1% increase in annual appreciation reduces break-even by roughly 1–2 years. The sensitivity is high because appreciation compounds on the full home value (leveraged), while the selling cost hurdle is fixed.
Down payment size
A larger down payment reduces the loan and monthly payment, but also increases the opportunity cost invested by the renter. These effects partially offset: a higher down payment doesn't dramatically change break-even year, but does change the absolute net-worth level at crossover.
More questions answered
What is the rent vs. buy break-even year?
The break-even year is the first year in which the buyer's cumulative net worth (home equity plus savings) matches or exceeds the renter's cumulative net worth (invested portfolio). Before this year the renter is ahead financially; after it the buyer leads. It accounts for selling costs, opportunity cost of the down payment, mortgage interest, appreciation, and the renter's invested surplus.
Why does it take so many years to break even on a home purchase?
Two main reasons. First, selling costs of 5–8% mean you immediately have to make back $20,000–32,000 on a $400k home just to return to zero. Second, in the early years of a 30-year mortgage, 75–80% of your payment is unrecoverable interest — not equity. Appreciation helps, but it compounds on the market value and is only realised net of selling costs when you sell.
How can I shorten the break-even period?
Four levers: (1) Make extra principal payments to build equity faster. (2) Choose a market with higher appreciation potential. (3) Negotiate lower selling costs — discount brokerages can cut commissions to 1–3%. (4) Buy at a lower price-to-rent ratio where the starting monthly costs are closer to rent. Leverage also helps: if you put 10% down instead of 20%, your return on equity is higher if appreciation is positive.
Model assumptions & disclosures
Equal-budget method. Both buyer and renter are assumed to spend the same total amount each month. The person with the lower required outlay invests the monthly difference into a diversified portfolio at the specified annual return. The renter also invests the down payment and estimated closing costs at the start of the comparison period.
Nominal figures. All rates — home appreciation, rent growth, and investment return — are nominal (not inflation-adjusted). Comparisons are internally consistent on a nominal basis.
No tax effects. Mortgage interest deductibility, capital gains exclusion on home sales ($250k/$500k), and investment account tax treatment are not modelled. Since the 2017 Tax Cuts and Jobs Act, fewer than 10% of taxpayers itemise, so the mortgage interest deduction is omitted as a default. Consult a tax professional for your specific situation.
Selling costs applied at horizon end. When computing buyer net worth at your planning horizon, the calculator deducts the specified selling-cost percentage from the home’s projected market value, reflecting the realistic proceeds from a sale.
