Rent vs Buy Calculator Guide: The True Cost of Homeownership vs Renting
Buying a home is not always financially superior to renting. The break-even point — where buying beats renting — is typically 5–8 years depending on market and costs.
The True Monthly Cost of Owning a Home
Most buyers compare their mortgage payment to rent and conclude buying is cheaper. This comparison omits 30–50% of the true cost of ownership. For a $400,000 home with $80,000 down (20%) at 7% APR on a 30-year mortgage: Monthly mortgage (P&I): $2,128. Property taxes (1.2% annually): $400/month. Homeowner's insurance: $150/month. Maintenance (1% ann
The Opportunity Cost of Your Down Payment
A $80,000 down payment invested in a diversified index fund at 7% average real return for 10 years grows to approximately $157,000. That $77,000 gain is the opportunity cost of using the money for a down payment — foregone investment growth. This does not mean renting is always better. Home equity grows through two mechanisms: principal paydown (th
Calculating the Break-Even Point
The break-even point is how long you must own a home before the total cost of buying equals the total cost of renting — and buying thereafter becomes cheaper. In high-cost markets (NYC, SF, LA) with high price-to-rent ratios, break-even can be 10–15+ years, making renting financially superior for most stays under a decade. In Sun Belt markets (Dall
When Buying Is Clearly the Right Financial Choice
Buying makes clear financial sense when: you plan to stay 7+ years in the same area (amortizes transaction costs), the local price-to-rent ratio is below 15 (annual rent × 15 > home price), you have a stable, growing income and can comfortably handle ownership costs at 28–30% of gross income, you have 20% down to avoid PMI, and your mortgage paymen
Frequently Asked Questions
Is renting throwing money away?
No — rent buys housing, just as a mortgage payment buys shelter. The portion of a mortgage payment going to interest (the majority in the early years) is also 'throwing money away.' What makes buying potentially superior over the long run is equity buildup and appreciation — but
What is a good price-to-rent ratio?
Price-to-rent ratio = Home Price ÷ Annual Rent for a comparable property. Below 15: buying is generally financially favorable. 15–20: marginal — depends on your timeline and market dynamics. Above 20: renting is typically the better financial choice for most time horizons. In 202
How much house can I afford on my salary?
The standard guideline: housing costs should not exceed 28% of gross monthly income (the front-end DTI ratio). On $80,000/year ($6,667/month), max housing PITI (principal, interest, taxes, insurance) = $1,867. At 7% APR with 20% down, that supports a home price of approximately $
What are the tax advantages of owning a home?
Homeowners can deduct mortgage interest on loans up to $750,000 (if itemizing) and property taxes up to $10,000 SALT cap. However, the 2017 tax law increase to the standard deduction ($15,000 single / $30,000 MFJ in 2025) means fewer than 10% of filers itemize. Most homeowners re
Should I put 20% down or use the money elsewhere?
20% down eliminates PMI (saving 0.5–1.5%/year), reduces your loan amount and monthly payment, and typically qualifies for better rates. Below 20%, FHA loans allow 3.5% down with mandatory MIP; conventional loans allow 3–5% down with PMI removed automatically at 20% equity. The ma
