Rent vs Buy Calculator
Compare the true cost of renting versus buying a home and find your break-even point.
How the Calculation Works
This calculator compares the true cost of homeownership against renting by accounting for all expenses and wealth-building factors:
Net Cost to Rent = (Rent + Insurance) − Investment Returns
The break-even point shows when buying becomes more cost-effective than renting, factoring in equity buildup and home appreciation.
Key Factors in Your Decision
- Time horizon: The longer you stay, the more likely buying becomes advantageous due to equity buildup.
- Opportunity cost: Your down payment could earn returns in the stock market (~7% historically).
- Home appreciation: U.S. homes average 3-4% annual appreciation, but varies by market.
- Hidden costs: Owners pay maintenance (1% of home value), taxes, insurance, and potential HOA fees.
When Renting Often Wins
- Short-term stays: If you’ll move within 3-5 years, transaction costs make buying expensive.
- High-cost markets: In cities where price-to-rent ratios exceed 20, renting often makes sense.
- Career flexibility: Renting allows easier relocation for job opportunities.
- Low rent areas: If rent is significantly below equivalent mortgage payments.
When Buying Often Wins
- Long-term commitment: Plan to stay 7+ years to recoup transaction costs.
- Building wealth: Each mortgage payment builds equity, unlike rent.
- Tax benefits: Mortgage interest and property taxes may be deductible.
- Stable housing costs: Fixed-rate mortgages protect against rent increases.
Frequently Asked Questions
How does the calculator determine the break-even year?
The break-even year is when the cumulative net cost of buying first becomes less than the cumulative net cost of renting. Net cost to buy = Mortgage payments + Taxes + Insurance + HOA + Maintenance + Opportunity cost on down payment − Equity gained − Appreciation. Net cost to rent = Rent payments + Renter’s insurance − Investment returns on down payment. The year both lines cross is the break-even point.
What is opportunity cost in the context of buying a home?
When you put money into a down payment, you can no longer invest those funds. The opportunity cost is the investment return that money would have earned in stocks or other assets instead. The calculator lets you enter an investment return rate and shows how forgone investment returns factor into the true cost of homeownership.
Does this calculator factor in home appreciation?
Yes — you enter an expected annual home appreciation rate, which the calculator compounds over your time horizon to estimate sale proceeds. It also models rent inflation (how much rent rises each year). Both rates significantly affect the break-even analysis, so try conservative (2%) and optimistic (5%) appreciation scenarios.
What closing costs and transaction fees does the calculator include?
This calculator focuses on ongoing monthly costs rather than one-time transaction costs. Typical closing costs of 2–5% when buying and 6–10% in seller commissions when selling are real expenses that favor renting at short time horizons. For a short intended stay, add estimated transaction costs to the buy column manually.
What time horizon makes buying financially better than renting?
It depends heavily on local market conditions, your down payment, and the rent-to-price ratio. In high-cost cities, break-even can take 10+ years due to high transaction costs and low yields. In affordable markets, buying can be cheaper than renting in 3–5 years. Run the calculator with your specific numbers — there is no universal answer.
