Rent vs. Buy Calculator

How This Rent vs. Buy Calculator Works

This calculator compares the true financial position of renting versus buying over your chosen time horizon. It accounts for all major costs and benefits on both sides.

What’s Included in the Buying Cost

The buying calculation includes mortgage principal and interest, property taxes, homeowner’s insurance, and annual maintenance costs. It subtracts the equity you build through both loan paydown and home appreciation to show your true net cost of ownership.

What’s Included in the Renting Cost

The renting calculation includes monthly rent (with annual increases), renter’s insurance, and models the growth of your down payment if invested in the market at your chosen return rate.

Beyond the Numbers

The right decision is not always purely financial. Buying offers stability, the ability to build long-term wealth, and freedom to customize your home. Renting offers flexibility, lower maintenance responsibility, and liquidity. Both have real value depending on your life situation and how long you plan to stay.

Factors That Can Shift the Rent vs. Buy Decision

How long you plan to stay in the home has more influence on this comparison than almost any other input. Buying involves upfront costs like closing costs and a down payment that take time to recover, so a short stay of only a year or two often favors renting, while staying five years or longer tends to favor buying as those upfront costs get spread across more time and equity has longer to build.

Your assumed investment return on the money you would otherwise use as a down payment matters too. This calculator assumes that money is invested if you rent, so a higher expected return narrows the gap between renting and buying, while a lower or more conservative return widens the advantage typically shown for buying.

Local market conditions can shift the comparison in either direction. In markets with fast-rising rents, buying tends to look more favorable over time because your mortgage payment on a fixed-rate loan stays level while rent continues to climb. In markets with flat or slowly appreciating home prices, the equity growth side of the buying calculation shrinks, which can narrow or even reverse the advantage.

Maintenance and unexpected repair costs are also worth thinking about beyond the percentage estimate used here. Older homes, homes with major systems nearing the end of their life, or homes in areas prone to weather-related repairs may run higher than a flat annual maintenance estimate, so it can help to budget some cushion beyond the calculator’s default assumptions.

Finally, remember that this tool measures the financial side of the decision. Non-financial factors, such as job stability, family plans, proximity to schools or work, and how much you value the flexibility to relocate quickly, often carry just as much weight as the dollar figures when deciding whether renting or buying fits your life right now.
