Rent vs Buy Calculator
A simplified 5-year comparison of renting versus buying a home.
How to use
- Enter the home price, down payment, mortgage rate, and term.
- Enter current monthly rent and the expected rent increase.
- Click Calculate to see the 5-year cost comparison and the verdict.
Simplified estimate only — not financial advice. Property taxes, insurance, maintenance, and closing costs are not included, so actual buying costs will be higher. Verify important decisions with a qualified professional.
What Is a Rent vs Buy Calculator?
A rent vs buy calculator compares the total cost of renting a home against buying a similar one over a fixed period — here, five years — so you can see which option leaves you better off financially. It is one of the most argued questions in personal finance, and also one of the most badly simplified. Buying is not always "building equity instead of throwing money away," and renting is not always the cheaper flexible choice; the honest answer depends on home prices, rent levels, how long you stay, and what the home does in value while you own it.
The comparison works by totaling both sides. Renting costs the monthly rent, growing by an annual increase each year. Buying costs the mortgage payments, but part of each payment builds equity you keep, and the home may appreciate; against that you must count the down payment tied up in the house, plus the interest, taxes, insurance, and maintenance a renter never pays. This simplified calculator uses the main ingredients — price, down payment, mortgage terms, rent, rent growth, and appreciation — to give a five-year verdict instead of a slogan.
How to Use the Rent vs Buy Calculator
- Enter the price of a home you might buy, your down payment percentage, the mortgage rate, and the term.
- Enter the monthly rent of a comparable home, plus the annual rent increase you expect.
- Enter the annual home appreciation you consider reasonable for the area (be modest — long-run US averages are a few percent).
- Click Calculate to compare the five-year cost of each path and see which comes out ahead, and by how much.
Why the Time Horizon Decides Everything
Buying has heavy upfront and exit costs — closing costs to get in, agent commissions to get out — that are spread over your years in the home. Over two or three years those transaction costs often overwhelm the equity built, and renting wins. Over seven to ten years, the same costs shrink per year while appreciation and principal payments accumulate, and buying usually pulls ahead. That is why the standard advice is to buy only if you expect to stay at least five years. This calculator runs exactly that five-year window so you can see where your numbers land.
Tips for a Fair Comparison
- Compare similar homes in similar neighborhoods — a verdict built on a cheap rental versus a dream house tells you nothing.
- Remember ownership costs beyond the mortgage: taxes, insurance, and maintenance (often budgeted around 1% of the home's value per year) are real costs renters avoid.
- Consider the opportunity cost honestly: a down payment invested elsewhere could also grow, which narrows buying's advantage.
Is renting really "throwing money away"?
No. Rent buys housing, flexibility, and freedom from maintenance, taxes, and market risk — the same way a mortgage payment includes interest, taxes, and insurance that also never come back. Economists compare renting's cost against the "unrecoverable" costs of owning, not the full mortgage payment, and this calculator follows that fairer logic.
Why does the calculator use a five-year period?
Because five years is roughly the horizon where buying starts to overcome its transaction costs for many households, and it is a realistic minimum stay to plan around. If you expect to move much sooner, renting usually wins by more; if you will stay much longer, buying's advantage typically grows beyond what the five-year view shows.
What appreciation rate should I assume?
Be conservative. US home prices have historically risen a few percent a year over very long periods, roughly tracking inflation plus a little, but local markets vary enormously and can fall. Run the comparison at 0% and at a modest positive rate to see whether your decision depends on optimistic appreciation — a decision that only works at high appreciation is a speculation, not a plan.
Does buying always beat renting in the long run?
Not always. In cities where home prices are extremely high relative to rents, renting and investing the difference can win indefinitely. The ratio of price to annual rent is the key signal: the higher it climbs, the stronger renting's case becomes. That is exactly the trade-off this tool is built to measure for your numbers.
