Rent vs Buy Calculator

The real break-even between renting and owning — in years, not guesses.

Plug in a home price, a realistic rent, and your assumptions about interest, taxes, and appreciation. We compute the full monthly cost of ownership (mortgage, taxes, insurance, HOA, maintenance), project both paths over your time horizon, and tell you when — or if — buying pulls ahead.

What this rent vs buy calculator actually models

It’s not just mortgage payments. Owning means property tax, homeowner’s insurance, HOA, ongoing maintenance (typically 1% of home value per year), and closing costs. Renting means steadily rising rent. The calculator simulates both paths month by month, tracks your mortgage amortization and home equity, and surfaces the year where your buying costs cross below cumulative rent.

Price-to-rent ratio: the fastest sanity check

Divide the home price by twelve months of rent for a comparable unit. Below 15, buying generally wins. Between 15 and 20, it depends on how long you stay. Above 20, renting is usually the math-correct move — the area is priced for appreciation, not for owner cash-flow.

Why time horizon is everything

Closing costs (2–5% of home price), realtor fees on the sale side (5–6%), and the mortgage paying mostly interest in early years mean short stays almost always lose to renting. The break-even typically sits between 5 and 9 years in most US markets. If you’re unsure whether you’ll stay that long, renting preserves optionality — that has real value the calculator can’t price in.

Assumptions this tool cannot make for you

Housing appreciation is uncertain and local. Property taxes can reset on sale. Major repairs (roof, HVAC) are lumpy and don’t fit neatly in a % annual assumption. Treat the output as a baseline — then stress-test with lower appreciation (2%) and higher maintenance (2%) to see how sensitive the decision is.

Frequently asked questions

Usually 5–9 years with typical inputs (6–7% rates, 3% appreciation, 2% rent increase). Shorter in areas with low price-to-rent ratios; never, in expensive coastal markets with price-to-rent above 25.
