About Rent vs Buy Calculator
Deciding whether to rent or buy a home is one of the biggest financial decisions you will ever make — and the answer is never the same for two people. Conventional wisdom says buying builds equity while renting is throwing money away, but that is a massive oversimplification. Buying comes with property taxes, maintenance, insurance, HOA fees, and closing costs that can easily eat up years of appreciation.
This calculator does the real math. It compares the total cost of each option over your chosen time frame, factoring in home appreciation, rent increases, and what your down payment could earn if invested instead. The results often surprise people: in many markets, renting and investing the difference beats buying, especially if you are not planning to stay for at least five years. Run your own numbers — the answer might change how you think about housing.
How to Use the Rent vs Buy Calculator
Start with the home price you are considering. If you are looking at a $350,000 house, enter that as the home price. Next, enter your down payment percentage. A standard 20% down on $350,000 is $70,000. Add your mortgage rate, property tax rate, and how long you plan to stay in the home. For the rent side, enter what a comparable home would cost to rent each month. If similar homes rent for $2,200, enter that.
Click calculate and the tool compares your net worth in both scenarios after your chosen time frame. It accounts for the down payment you would make, the equity you would build, the maintenance costs (typically 1% of home value annually), and what your down payment plus monthly savings could earn if invested in the stock market at a conservative 7% return. The result page shows a side-by-side comparison so you can see exactly which option leaves you ahead.
Interpreting Your Results
Imagine you are looking at a $400,000 home with 20% down and a 6.5% mortgage rate. You plan to stay 7 years. The calculator might show that buying builds $95,000 in equity, while renting and investing the difference grows your portfolio to $112,000. Renting wins by $17,000. But if you plan to stay 12 years, buying might pull ahead because the transaction costs get spread over more years and the mortgage balance shrinks faster. The crossover point varies by market, but in high-cost areas like San Francisco or New York, renting often wins even at 10 years unless home prices appreciate aggressively.
When to Use This Calculator
Use this calculator when deciding whether to rent or purchase a home. It is most useful for people who plan to stay in an area for at least 3-5 years. First-time homebuyers use it to compare monthly costs and long-term wealth building. Relocating professionals use it to evaluate whether buying makes sense in a new city. Use it before making one of the biggest financial decisions of your life.
How to Interpret Your Results
In most US markets, buying becomes cheaper than renting after 3-7 years thanks to principal paydown, tax benefits, and appreciation. A $300,000 home with 6.5% mortgage rate and 10% down payment costs approximately $2,300 monthly including taxes and insurance, versus $1,800 to rent a comparable property. However, over 7 years, the buyer builds $45,000 in equity and saves $18,000 in taxes, while the renter pays $151,000 with nothing to show. If you move within 3 years, renting is usually cheaper due to transaction costs of 5-8% of the home value.
