How this calculator helps
Renting versus buying is rarely just about one monthly payment. Buying includes taxes, insurance, HOA dues, maintenance, closing costs, and the down payment tied up in the home.
Renting can look simpler month to month, but over longer horizons rising rent may change the balance. Time horizon is one of the biggest variables in the decision.
This calculator is intentionally high-level. It is designed to frame the tradeoff clearly, not replace lending, tax, or legal advice.
How the math works
Monthly mortgage payment uses the standard amortization formula based on loan principal, rate, and term.
Total monthly owner cost = mortgage payment + property tax + home insurance + HOA + maintenance.
Buying total = down payment + closing costs + monthly owner cost over the time horizon. Renting total grows rent annually based on your entered increase rate.
Worked examples
Short three-year horizon
A buyer may move again soon and does not have a long horizon to spread closing costs.
- • Expected years in home: 3
- • Closing costs included
- • Rent compared over same period
Short stays often make renting look more flexible and cheaper on a pure cash basis.
Long ten-year horizon
A household plans to stay put for a decade and expects rent to rise over time.
- • Expected years in home: 10
- • Annual rent increase: 3%
Longer horizons often improve the relative case for buying, depending on rate and maintenance assumptions.
High-interest environment
Mortgage rates are elevated and borrowing costs noticeably increase owner payments.
- • Interest rate entered higher
- • Monthly rent still competitive
High rates can keep renting attractive longer, even when the home price itself seems reasonable.
