The rent vs buy decision is the biggest financial choice most people face, and the answer depends on far more than comparing monthly payments. Buying builds equity but locks up capital, carries maintenance costs of 1-2% of home value annually, and only makes financial sense if you stay long enough to offset transaction costs. In most markets, you need to own for at least 5-7 years before buying beats renting financially. This calculator compares the true total cost of each option over your intended time horizon, factoring in mortgage payments, property taxes, maintenance, opportunity cost of your down payment, rent increases, and home appreciation.

How to Use This Calculator
- Enter the home purchase price and your expected down payment
- Set the mortgage rate and term — check current rates for accuracy
- Enter your current monthly rent and expected annual rent increases (typically 3-5%)
- Set the expected home appreciation rate for your market (historically 3-4% nationally)
- Compare the total cost of renting vs buying over 5, 10, 15, and 30 year horizons
How It Works
Comparing renting vs buying requires looking beyond monthly payments. This calculator factors in all costs of ownership, rent increases, opportunity cost of your down payment, and equity building to give a complete financial picture.
The basic rule:
- Buying costs: Mortgage payment + property tax + insurance + maintenance
- Renting costs: Monthly rent (increasing annually) + renter's insurance
- Opportunity cost: Down payment invested at market returns if renting instead
- Break-even year = when total buying advantage exceeds total renting advantage
This calculator focuses on financial comparison only. Non-financial factors like flexibility, customization freedom, stability, and lifestyle preferences also matter significantly in the rent-vs-buy decision.
Tips & Considerations
- The opportunity cost of your down payment is real. $80K invested in index funds at 8% becomes $173K in 10 years. That growth is lost when you put it into a down payment.
- Maintenance, repairs, property tax, and insurance add 30-40% on top of your mortgage payment. A $2,000 mortgage really costs $2,600-$2,800 per month.
- Buying makes more financial sense the longer you stay. Transaction costs of 8-10% (agent fees, closing costs) need years of appreciation to recover.
- In high-cost cities like SF or NYC, renting and investing the difference often beats buying. In lower-cost markets, buying almost always wins after 5 years.
Frequently Asked Questions
Is it cheaper to rent or buy?
It depends on your local market, how long you plan to stay, mortgage rates, and rent prices. In expensive markets with low rents, renting may be better financially. In affordable markets or with long time horizons (7+ years), buying often wins. This calculator helps you compare for your specific situation.
What is the break-even point for buying?
The break-even point is when the total cost of buying (including opportunity cost of the down payment) becomes less than the total cost of renting. This typically ranges from 3-7 years depending on market conditions. If you plan to move before the break-even point, renting is usually better financially.
What is opportunity cost in rent vs buy?
Opportunity cost is what your down payment could earn if invested in the stock market instead of a home. If you put $70,000 down on a house, that money can't earn investment returns. This calculator assumes the renter invests the down payment equivalent and any monthly savings at the specified investment return rate.
Does this include home appreciation?
The equity calculation accounts for mortgage principal paydown. Home appreciation varies widely by market and is difficult to predict, so this calculator focuses on known costs. Historically, home prices have appreciated about 3-4% annually on average, but past performance doesn't guarantee future results.
What costs are included for homeownership?
This calculator includes mortgage payments (principal + interest), property taxes, homeowner insurance, and maintenance costs. It does not include closing costs, HOA fees, or home improvement costs, which would make buying more expensive. You can increase the maintenance percentage to roughly account for these.
How much should I budget for home maintenance?
The common rule of thumb is 1% of your home's value per year for maintenance. So a $350,000 home would need about $3,500/year. Older homes may need 2-3%. This covers routine repairs, appliance replacement, and upkeep but not major renovations.
