Rent vs Buy Calculator
Compare the true financial cost of renting versus buying a home. Unlike basic calculators, we factor in taxes, maintenance, and the opportunity cost of your down payment.
Quick Answer: Is it better to rent or buy?
The answer depends entirely on how long you plan to stay and current local market conditions. Buying a home acts as a forced savings account and builds equity over time, but it comes with immense unrecoverable costs like mortgage interest, closing fees, property taxes, and maintenance. If you plan to move in less than 5 years, renting is almost always mathematically cheaper due to the high transaction costs of selling a house.

The "Rent is Throwing Money Away" Myth
A common piece of traditional advice is that "renting is throwing money away." But the reality is that when you buy a house, you throw away a lot of money too—mostly to the bank and the government. These unrecoverable costs are identical to "rent."
Unrecoverable Sunk Costs of Renting
- Monthly Rent payments
- Renter's Insurance
Unrecoverable Sunk Costs of Buying
- Interest paid to the bank on the mortgage
- Annual Property Taxes
- Annual Maintenance (average 1% of home value)
- HOA fees
- Closing costs (buying) and Agent commissions (selling)
The Power of Opportunity Cost
When modeling whether renting or buying is mathematically better, you cannot ignore Opportunity Cost. Imagine two identical neighbors: Buyer Bob, and Renter Rita.
Bob buys a $400,000 house and puts down an $80,000 down payment. He pays his mortgage to slowly build equity in his home structure.
Rita rents the identical house next door for $2,000/mo. Because she didn't buy the house, she still has her $80,000 down payment sitting in her bank account. She takes that $80,000 and puts it into an S&P 500 Index Fund returning 7% a year. Over 30 years, Rita's stock portfolio will likely grow massively, potentially far exceeding the equity Bob built in his physical house.
Our Rent vs Buy calculator explicitly calculates Ritay's opportunity cost to give you a true, apples-to-apples comparison of net worth.

Frequently Asked Questions
Is it always better to buy than to rent?
No. While buying a home builds equity over time, it comes with massive unrecoverable "sunk" costs like property taxes, maintenance, closing costs, and mortgage interest. Depending on your local market conditions and how long you plan to stay in the home, renting can sometimes be significantly cheaper mathematically.
What is the "opportunity cost" in the rent vs buy calculation?
If you buy a house, you have to lock up a large amount of cash for the down payment and closing costs. Opportunity cost is the money you would have made if you continued renting and invested that cash into the stock market instead. A true rent vs buy model must factor this in.
How long do I need to stay in a house to break even?
Generally, financial advisors recommend staying in a house for at least 5 to 7 years. Because of high initial closing costs (when buying) and agent commission fees (when selling), if you move too quickly, those transaction costs will completely wipe out any equity you gained.
Are there hidden costs to buying a home?
Yes. Renters only pay rent and renters insurance. Buyers must pay their mortgage, annual property taxes, homeowners insurance, HOA fees, and are fully responsible for all maintenance and repairs (new roofs, broken water heaters, etc.), which generally averages 1% of the homes value every single year.
