Rent vs. Buy Calculator

The True Cost of Buying

People often compare a mortgage payment to rent — but this dramatically understates the true cost of homeownership. The full picture includes:

• •Closing costs: Typically 2-5% of the purchase price upfront — $8,000-$20,000 on a $400,000 home.
• •Property taxes: Average 1.1% of home value annually, though it varies enormously by state and county.
• •Maintenance: The classic rule is 1% of home value per year for repairs and upkeep — $4,000/yr on a $400K home.
• •Insurance: Homeowners insurance plus potential flood or earthquake coverage.
• •Selling costs: Realtor commissions and fees total ~6% of the sale price when you eventually sell.

The Opportunity Cost of the Down Payment

One of the most overlooked factors is what you could do with your down payment if you rented instead. A 20% down payment on a $400,000 home is $80,000. If that money were invested in a diversified stock portfolio earning 7% annually, it would grow to roughly $157,000 over 10 years.

This does not mean renting is always better — home equity is also wealth. But it does mean the comparison is never as simple as "rent is throwing money away." Every rent payment buys you flexibility, maintenance-free living, and an alternative to tying up capital in a single illiquid asset.

This calculator includes this opportunity cost by assuming the down payment (and the monthly savings difference, if any) would be invested if you rented.

The Break-Even Point

The "break-even point" is the year at which buying becomes cheaper than renting when you account for all costs and equity. Before this point, renting is the better financial choice. After it, buying wins.

In expensive markets like San Francisco or New York, break-even can take 10-15+ years due to high purchase prices and property taxes. In more affordable markets with strong appreciation, buying may break even in 4-6 years.

If you are not confident you will stay in a home past the break-even point, renting is likely the smarter financial move — even if buying "builds equity." The transaction costs alone make frequent home purchases very expensive.

When Buying Makes Sense

Buying tends to be the better financial choice when:

• •You plan to stay for 7+ years, allowing time to recoup transaction costs.
• •Local rent-to-price ratios are high — if annual rent exceeds 5-6% of the home's value, buying often wins.
• •Home appreciation is expected to outpace general investment returns in your market.
• •You value stability, customization, and the emotional benefits of homeownership.

When Renting Makes Sense

Renting is often underrated as a financial strategy. It is particularly strong when:

• •Your timeline is short — under 5 years — making it hard to recoup purchase and selling costs.
• •The price-to-rent ratio in your market is very high (homes are expensive relative to rents).
• •Mortgage rates are high and you expect them to fall, making refinancing attractive in a few years.
• •You value geographic flexibility for career opportunities.

Non-Financial Factors

The numbers are only part of the story. Some of the most important rent-vs-buy factors are qualitative:

• •Stability: Renters can face non-renewal or significant rent hikes. Homeowners have fixed payments and can't be evicted without cause.
• •Customization: Homeowners can renovate, paint, and modify their space freely.
• •Community roots: Homeownership tends to encourage longer-term community involvement.
• •Financial discipline: For some people, a mortgage acts as a forced savings mechanism that renting does not replicate.
