A rent vs buy calculator is a free browser tool that estimates the true cost of renting versus buying a home over a custom timeline. It models mortgage cash flow, ownership expenses, equity growth, rent escalation, and investment opportunity cost side by side. Everything runs locally in your browser with no account and no data sent to any server.
How it works
- Enter your buying inputs including home price, down payment mode, interest rate, term, and ownership costs.
- Enter your renting assumptions such as monthly rent, annual rent increase, renter insurance, and expected investment return.
- Review instant projections for break-even timing, total cost, net worth impact, and yearly comparison across your time horizon.
When to use this tool
- Evaluating whether buying now is financially stronger than continuing to rent in your current market.
- Comparing short versus long holding periods before committing to a home purchase decision.
- Testing how appreciation, rent growth, and investment return assumptions change break-even timing.
- Estimating ownership cost impact from tax, insurance, maintenance, HOA, and transaction fees.
- Benchmarking financing assumptions with the Mortgage Calculator, repayment profiles from the Loan / EMI Calculator, and growth assumptions in the Compound Interest Calculator.
Financial outcomes are only one part of the rent-versus-buy decision. Mobility needs, maintenance responsibility, local market volatility, and personal lifestyle priorities can outweigh purely monetary projections. Time horizon is critical because transaction costs are front-loaded while equity and appreciation effects usually compound later.
This calculator runs entirely in your browser using JavaScript — no server uploads, no account required, and no data stored. Your income, debt, and housing assumptions never leave your device. You can model dozens of scenarios without creating a profile or sharing any personal information.
Frequently asked questions
Is it better to rent or buy a home?
It depends on home price, rent level, financing rate, ownership costs, and how long you plan to stay. Buying often improves over longer horizons when equity builds, while renting can be financially better for shorter stays or when investment returns on the down payment exceed home appreciation.
How long does it take for buying to be cheaper than renting?
The timeline varies by market and assumptions. In many scenarios the break-even point appears between 5 and 10 years, but it can shift earlier or later based on rates, appreciation, rent growth, and transaction costs. This tool computes the specific break-even year for your inputs.
What is the breakeven point in rent vs buy?
The breakeven point is the first year when the estimated net cost of buying becomes lower than renting. Net cost includes recurring housing expenses, transaction costs, equity growth, and investment opportunity cost on the down payment.
What costs are included in buying a home?
This calculator includes down payment, closing costs, mortgage principal and interest, property tax, home insurance, HOA, maintenance, and selling costs. It also models equity and optional tax savings to provide a net financial comparison against renting.
What happens to my down payment if I rent instead?
If you rent, your down payment is treated as an invested amount growing at your selected return assumption. The projected future value is included as renter net worth in this model, representing the opportunity cost of using cash for a home purchase.
How does home appreciation affect the rent vs buy decision?
Higher home appreciation generally builds owner equity faster and can move break-even earlier, while lower appreciation does the opposite. Because appreciation is uncertain, this tool includes sensitivity analysis scenarios to compare outcomes across different annual appreciation rates.
