Compare total costs of renting vs buying over time
The rent vs buy debate isn't just about monthly payments — it's about the full financial picture over time. A mortgage payment might look similar to your rent check, but buying a home also means property taxes, maintenance costs, homeowner's insurance, and the opportunity cost of your down payment sitting in equity instead of investments. On the flip side, renting means your monthly costs go up over time with no asset to show for it.
This calculator compares both paths honestly. Enter your local home price, current mortgage rate, expected rent increases, and how long you plan to stay — and it shows you the true total cost of each option, year by year. You'll also see a break-even year: the point where buying finally becomes cheaper than renting on a cumulative basis.
For example, if you're looking at a $400,000 home with a 6.8% mortgage rate and currently paying $2,200/month in rent, the break-even point might not arrive until year 7 or 8. Move before then, and renting likely cost you less overall. Stay longer, and ownership wins — especially with appreciation factored in.
Most simple "rent vs buy" comparisons only look at the mortgage payment versus rent. This tool goes deeper. It includes annual home appreciation (typically 3–4% historically), yearly maintenance costs (usually estimated at 1% of home value per year), and how rent tends to increase 3–5% annually in most U.S. markets. These compounding factors change the math dramatically over a 10 or 20-year horizon.
One factor people often overlook is the opportunity cost of equity. If you put $80,000 down on a home, that money is no longer available to invest in the stock market or other assets. This calculator factors in what that capital could have grown to, giving you a fair comparison. The goal isn't to tell you what to do — it's to show you both outcomes with realistic numbers so you can make a confident decision.
You can adjust every assumption: appreciation rate, rent increase percentage, investment return rate, closing costs, and more. That flexibility makes it useful whether you're in a high-cost city like San Francisco or a more affordable market in the Midwest.
It depends heavily on local home prices, your mortgage rate, and how fast rents are rising. In most markets, buyers need to stay at least 5–7 years to recoup closing costs and come out ahead. Use the break-even year feature on simple-calculator.online to find the exact number for your specific situation.
You can factor in mortgage interest deductions indirectly through your net cost inputs. Keep in mind that since the 2017 tax law changes, fewer homeowners actually itemize deductions — so this benefit is smaller than it used to be for many buyers.
The national historical average is roughly 3–4% per year, though markets like Austin or Miami have seen much higher short-term appreciation. For a conservative estimate, stick with 3%. For a more optimistic projection in a hot market, 5% is reasonable — just know that past trends don't guarantee future results.
