Buy vs Rent Break-Even Calculator: How Long Until Buying a Home Pays Off?
The honest answer to a question most people get wrong
Ask anyone when buying a home starts to make financial sense, and they’ll probably say “five years.” It’s been the rule of thumb for decades. The problem is, it’s no longer accurate, and it was always too simple.
In 2025, analysis from Realtor.com put the average break-even timeline for new US buyers at around 10 years, up from the traditional five. Zillow’s research has placed it even higher in some markets. Why? A combination of high mortgage rates, elevated home prices, and transaction costs that are harder to recover than they used to be.
But here’s the thing. The break-even point isn’t one number. It’s your number, based on your home price, your down payment, your local market, and critically, what you’d do with that money if you didn’t buy.
That’s what this calculator figures out.
What “break-even” actually means
The break-even year is the point at which your net worth as a homeowner overtakes your net worth as someone who rented and invested the difference instead.
It’s not just about whether your home has gone up in value. It accounts for:
- The down payment you tied up (and what it could have earned in the market)
- Closing costs when you buy (typically 3 to 10% depending on market)
- Mortgage interest, property tax, and maintenance every year
- Agent fees and selling costs when you eventually sell (5 to 8%)
- How much your rent would have risen if you’d stayed renting
Only when all of those costs are accounted for, and your home equity exceeds what your invested alternative would have grown to, have you genuinely broken even.
Why the five-year rule broke down
The five-year rule made sense when mortgage rates were around 3 to 4% and home prices were lower relative to incomes. At those rates, buying was cheap enough that break-even came quickly.
At 6.5 to 7% mortgage rates, a much larger portion of your early payments go to interest rather than building equity. On a $400,000 loan at 6.5%, you pay roughly $26,000 in interest in year one alone, while reducing your actual loan balance by less than $7,000. That interest cost has to be recovered by appreciation before you’re ahead.
Add in 3% closing costs on the way in and 6% selling costs on the way out, and you’re starting the clock with roughly 9% of the home’s value already working against you. Appreciation has to run for several years just to get you back to zero.
The factor almost everyone ignores: opportunity cost
The biggest thing missing from most break-even thinking is what your down payment could have done instead.
If you put $80,000 down on a home, that money is no longer invested. Over 10 years at a 7% annual return, that $80,000 would have grown to roughly $157,000. That $77,000 gain is money you gave up by buying instead of renting and investing.
This isn’t an argument against buying. It’s just a cost that deserves to sit on the same page as mortgage interest and property tax. The calculator above includes it. Most others don’t.
When buying wins despite the maths
Here’s what’s interesting: buying can still come out ahead even when the investment return looks better on paper. The reason is leverage.
When you buy a $400,000 home with an $80,000 down payment, you’re getting price appreciation on the full $400,000, not just your $80,000. If the home appreciates 4% in a year, that’s $16,000 in gains on an $80,000 investment, which works out to a 20% return on your actual cash. No index fund gives you 5:1 leverage for free.
This is why markets like the UK, Germany, and the Netherlands, where property appreciation is lower, tend to have longer break-even points than markets with stronger price growth, even when mortgage rates are similar.
How long does it actually take? By market
These are realistic break-even ranges based on current market conditions, using typical inputs. Your number will vary.
- United States — 7 to 12 years, depending on location. High-appreciation markets like the Northeast can be closer to 7. Slower markets in the South and Midwest can push past 12.
- United Kingdom — 8 to 13 years. High transaction costs including stamp duty and legal fees mean you need significant time to recover the entry cost alone.
- Germany — 10 to 15 years. Buying costs in Germany are among the highest in Europe, typically 10 to 12% of the purchase price, making this one of the harder markets to break even in quickly.
- France — 9 to 14 years. Notary fees and other transaction costs sit around 7 to 8%, extending the early recovery period.
- Netherlands — 7 to 11 years. Lower selling costs help, though high demand and prices mean the opportunity cost of the down payment is significant.
The questions that actually determine your break-even
Before running the numbers, these are the three that matter most.
How long do you plan to stay? This is the most important variable by far. If you’re likely to move within five years, the maths almost never favour buying. If you’re planning a decade or more, it shifts significantly.
What would you do with the down payment if you didn’t buy? If you’d invest it consistently, the renting and investing option is much stronger. If it would sit in a savings account or get spent, buying forces a kind of wealth-building discipline that investing doesn’t.
What’s your local market doing? National averages mask huge regional variation. A home in a Northeast US market appreciating at 8 to 10% has a very different break-even timeline than one in a flat Midwest market at 1 to 2%.
A note on what this calculator doesn’t measure
Financial outcomes aren’t the only thing that matters when deciding whether to buy or rent.
Owning a home gives you stability. You can’t be asked to leave, you can renovate it, and your housing cost on a fixed mortgage doesn’t rise year on year. These things have real value that doesn’t show up in a spreadsheet.
Renting gives you flexibility, to move for a job, to downsize, to not deal with a broken boiler on a Sunday morning. That has value too.
This calculator helps you understand the financial break-even. What you do with that information is a bigger, more personal decision.
