What Rent vs. Buy Calculator does
The Rent vs. Buy Calculator on Calculator.net lets users model the long-term financial trade-offs of renting versus owning a home. By inputting variables like home price, down payment, interest rate, loan term, and ongoing costs such as property tax, insurance, and maintenance, the tool projects the total monthly cost of buying over a 30-year horizon and compares it against the cumulative cost of renting. The output includes a clear verdict—"Buying is cheaper if you stay for 5.0 years or longer, otherwise renting is cheaper"—along with a year-by-year cost breakdown that helps users see how expenses shift over time.
