How the comparison works
The calculator follows both paths month by month and compares what you would own if you sold at the end of each year:
- Buying: the home's value, minus the loan balance and selling costs, plus anything the buyer invested in months when owning cost less than renting.
- Renting: the down payment and closing costs, invested instead, plus the difference in any month when owning costs more than renting.
Because both paths spend the same cash, the comparison is about what that cash builds, not just the monthly payment. In the example the first month costs $3,275.44 to own and $2,215.00 to rent.
Why time matters most
Buying has large one-off costs: closing costs going in and selling costs coming out. They take years of equity growth to recover. Over 10 years the example ends with renting ahead by about $17,491; over 20 years it ends with buying ahead by about $102,443, breaking even in year 13. If you may move within a few years, renting often costs less overall.
The assumptions that swing the answer
- Rent: at $3,000 a month instead of $2,200, the example ends with buying ahead by about $122,405 and breaks even in year 4.
- Investment return: at 7% instead of 5%, it ends with renting ahead by about $50,925. Returns are not guaranteed and can be negative.
- Home prices: growth is an assumption, not a forecast. Prices can fall, and a small change compounds over many years.
Owning also carries risks and responsibilities a landlord usually carries for renters, such as repairs and rising taxes and insurance, while renting keeps you flexible (CFPB: is it the right time to buy?).
What this calculator does not include
- Income taxes: the mortgage interest deduction, capital gains exclusions and taxes on investment returns.
- Changes in the mortgage rate (it is a fixed-rate loan), insurance or HOA dues over time, and utility differences.
- Security deposits, moving costs and the value of stability or flexibility.
Up-front and ongoing costs of buying are explained by the CFPB (what are all the costs of buying a home?). Results are estimates based on your assumptions, not financial advice.
Methodology and testing
The mortgage payment and PMI come from the same tested engine as our mortgage calculator. Automated tests compare every year's net worth on both paths with an independent month-by-month simulation, and check that both paths account for the same cash. How we build and test calculators.
