How This Calculator Works
Most rent vs. buy calculators only compare your monthly rent to your mortgage payment — which is misleading. This calculator computes the true net cost of each path over your time horizon:
- Buying net cost = down payment + closing costs + all mortgage payments + property tax + insurance + maintenance + HOA + selling costs − home sale proceeds
- Renting net cost = total rent paid − investment growth on the down payment and any monthly savings (when buying costs more per month, the renter invests the difference)
The break-even point is the year when the cumulative net cost of buying drops below the cumulative net cost of renting. Before that year, renting is cheaper on a true cost basis. After it, buying is cheaper.
The Opportunity Cost of a Down Payment
One of the most overlooked costs of buying is opportunity cost — what your down payment could have earned if invested instead. A $80,000 down payment invested at 7% annually grows to about $157,000 in 10 years. That growth is a real financial advantage of renting that most comparisons ignore.
This doesn't mean renting is always better — home equity builds too, and home appreciation can exceed stock market returns in some markets. The calculator accounts for both sides.
What the Monthly Comparison Misses
A mortgage payment may be lower than rent in some markets, but it's not your true cost of owning. Homeowners also pay:
- Property taxes: Typically 1–2% of home value per year — often $4,000–$10,000 annually.
- Insurance: $1,400–$2,500/year depending on location.
- Maintenance: Budget 1–2% of home value annually — a $400,000 home costs $4,000–$8,000/year on average to maintain.
- PMI: If your down payment is less than 20%, you'll pay private mortgage insurance — typically 0.5–1% of the loan annually — until your loan balance drops to 80% of the original purchase price.
- Transaction costs: Buying costs 2–5% and selling costs 4–6% of the home price (seller's agent plus closing fees; buyer's agent is separately negotiated post-NAR settlement). On a $400,000 home, that's $24,000–$44,000 in transaction friction that you need home appreciation to recover.
When Buying Makes More Sense
- You plan to stay for 5+ years (longer = more favorable for buying)
- Local home prices are expected to appreciate steadily
- Mortgage payments are comparable to local rents
- You value stability, customization, and building equity
When Renting Makes More Sense
- You may need to move within 3–5 years
- Home prices are very high relative to rents (high price-to-rent ratio)
- You would invest the down payment at a high expected return
- You value flexibility and lower financial risk
Frequently Asked Questions
Is it better to rent or buy a home?
It depends on how long you plan to stay, local home prices, mortgage rates, and what you would do with the down payment instead. Buying generally becomes advantageous after 4–7 years in most markets, but the break-even point varies significantly by location. This calculator finds your specific break-even year.
What is the break-even point for buying vs. renting?
The break-even point is the number of years after which the total cost of buying — including mortgage, taxes, insurance, maintenance, and selling costs, minus equity — becomes lower than the total cost of renting, including the investment return you would have earned on the down payment. In most U.S. markets this falls between 3 and 8 years.
What costs should I include when buying a home?
Beyond the mortgage payment, homeowners pay property taxes, homeowner's insurance, HOA fees (if applicable), maintenance and repairs (typically 1–2% of home value per year), and closing costs when buying (2–5%) and selling (typically 4–6%: seller's agent commission plus title and closing fees; buyer's agent is now separately negotiated following the 2024 NAR settlement).
What is opportunity cost in the rent vs. buy decision?
Opportunity cost is what your down payment and closing costs could have earned if invested instead of used to buy a home. If you put $80,000 down, that money could have grown in the stock market. This is a real cost of buying that is often overlooked. This calculator accounts for it by comparing your home equity to what that same money would have grown to if invested.
How does home appreciation affect the rent vs. buy decision?
Home appreciation builds equity over time, reducing the true cost of buying. Higher appreciation rates make buying more attractive. However, appreciation is not guaranteed and varies by market. The U.S. national average has been roughly 3–4% annually over the long run, but specific markets have seen much higher or lower rates.
