Free Rent vs. Buy Calculator
Compare the total cost of renting against the net cost of buying — including equity and appreciation — over the years you'd stay. Buying's cost totals your down payment, closing costs, and monthly payments, then subtracts what you'd walk away with if you sold — the home's projected value minus your remaining loan balance. The comparison depends heavily on how long you'd actually stay, since upfront costs like closing fees are spread over fewer years the sooner you'd move.

Comparing renting and buying honestly
"Renting is throwing money away" and "buying is always an investment" are both too simple. Renting buys you housing and flexibility. Buying buys you housing plus a slowly accumulating asset, in exchange for large upfront costs and every repair bill. The comparison only becomes meaningful once you fix a time period and count what you'd actually walk away with.
A worked example. $1,800/month rent rising 3% a year, against a $350,000 home with 20% down at 6.5%, 1.1% property tax, $3,000/year insurance and maintenance, 2% closing costs, 3% annual appreciation — over 7 years:
Renting
Total rent paid — $165,509 (rising to $2,149/mo by year 7)
Buying
Down payment $70,000 + closing $7,000
Monthly costs $2,341 × 84 months
Total cash out — $273,612
Less equity if sold: $430,456 value − $253,165 owed = $177,290
Net cost of buying — $96,322
Buying comes out about $69,187 cheaper over these seven years — but that conclusion rests heavily on the 3% appreciation assumption.
Why time horizon decides almost everything
Buying carries large one-time costs — in the example, $7,000 in closing costs alone, plus selling costs later that this calculation doesn't include. Those are spread across however long you stay. Over two years they're crushing; over ten they're minor.
The other factor is amortization. Early mortgage payments are mostly interest, so equity builds slowly at first and accelerates later. Both effects push the same direction: the longer you stay, the better buying looks. Short stays usually favor renting even in a rising market.
The appreciation assumption is doing a lot of work
At 3% a year the example home is worth $430,456 after seven years — about $80,000 of the equity credited back. Set appreciation to 0% and buying's advantage largely disappears. Set it negative and renting wins clearly.
Nobody knows future appreciation. It's worth running the comparison at 0% as a deliberately conservative case: if buying still wins with no appreciation at all, the decision is robust. If it only wins at 4–5%, you're relying on a forecast rather than arithmetic.
Costs of buying people routinely forget
- Selling costs. Agent commissions and closing fees commonly run 6–8% of the sale price, taken straight out of the equity credited here.
- Maintenance. Roughly 1% of home value per year is a common planning figure, and it's lumpy — a roof or HVAC system arrives all at once.
- Higher utilities. Houses generally cost more to heat, cool, and maintain than comparable apartments.
- Opportunity cost. That $70,000 down payment could have been invested instead. This comparison doesn't credit renting for that.
The last one matters more than it seems. A fair comparison assumes the renter invests the difference — and many don't, which is a behavioral argument for buying rather than a mathematical one.
What renting genuinely buys you
Flexibility has real value that doesn't appear in dollars. Being able to relocate for a job, leave a neighborhood that changes, or downsize quickly is worth something, and a home is one of the least liquid assets most people own. Renters also have predictable costs — a failed water heater is the landlord's problem.
If there's a meaningful chance you'll move within a few years, that alone can settle the question regardless of what the arithmetic says.
What this calculator doesn't include
It doesn't model selling costs, the mortgage interest deduction or other tax effects, PMI if your down payment is under 20%, HOA dues, renters insurance, or investment returns on money not spent on a down payment. It assumes steady appreciation and rent increases rather than the uneven reality of both, and it assumes you'd sell at the end of the period.
Use it to understand which factors actually move the answer for your situation — time horizon and appreciation, mostly — rather than as a verdict.
Frequently Asked Questions
How is the cost of buying calculated?
It totals your down payment, closing costs, and monthly payments (principal, interest, property tax, insurance, and maintenance) over the years you'd stay, then subtracts what you'd walk away with if you sold — the home's projected value minus your remaining loan balance.
Does this include closing costs?
Yes — enter an estimated closing cost percentage (commonly around 2-5% of the home price) and it's added to your upfront cost of buying.
What about home appreciation?
The calculator projects the home's value forward at your entered appreciation rate and credits that value (minus your remaining mortgage) back against the cost of buying, since that equity is money you'd recover by selling.
Should I always buy if this says it's cheaper?
Not necessarily — this only compares dollar costs. Renting offers flexibility and fewer surprise expenses; buying builds equity but ties up capital and comes with maintenance responsibility. Your personal plans matter as much as the math.
Is this financial advice?
No — this is an estimate for planning purposes only, not financial advice. Real appreciation, rent increases, and costs vary and are never guaranteed.
