Rent vs. Buy

How Rent vs. Buy Works

Net Cost Buy = Costs Paid − Sale Proceeds | Net Cost Rent = Total Rent − Investment Gains on Down Payment

Break-Even

Break-Even Year — The number of years after which buying becomes cheaper than renting on a cumulative net-cost basis. If you stay longer than this, buying wins financially. If you move sooner, renting wins.

Opportunity Cost

Down Payment Opportunity Cost — The money you would have earned by investing your down payment and closing costs in stocks (assumed 7% return) instead of using them for a home purchase. This is the primary financial advantage of renting.

Home Equity

Equity Accumulation — The wealth you build through principal paydown and home appreciation, minus selling costs. This is the primary financial advantage of buying.

Transaction Costs

Closing & Selling Expenses — Buying typically costs 3–5% in closing costs upfront and 5–8% in selling costs at exit. These transaction costs create a significant upfront hurdle — the main reason buying only wins if you stay long enough to recover them.

How to Use

1. Enter the home price, down payment percentage, mortgage rate, and closing costs for the buy scenario.
2. Input your monthly rent, expected annual rent increase rate, and renters insurance for the rent scenario.
3. Set the property tax rate, maintenance percentage, and home appreciation rate (national averages are shown as defaults).
4. Choose your expected holding period — try different values to see how the break-even point shifts.
5. Compare the two paths at different time horizons: the chart shows cumulative costs year by year, and the break-even year tells you which choice is better for your specific timeline.

Common Uses

• •Compare the total lifetime cost of renting versus buying a home over different time horizons to find your financial break-even point.
• •Understand how long you need to stay in a home for the equity and appreciation benefits of buying to outweigh upfront transaction costs.
• •Model how changing home prices, mortgage rates, and rent increases affect whether renting or buying is the better financial decision.

Understanding the Result

Frequently Asked Questions

How is the break-even year calculated?

We model two paths side by side for each year. The renting path tracks all rent paid, adjusted for annual increases. The buying path tracks total costs (P&I, taxes, maintenance, PMI, closing costs) minus net home equity gained (sale proceeds at that year). We also account for the opportunity cost of your down payment — if you rented, you could invest that cash in stocks earning 7%. The break-even year is when cumulative buying costs first fall below cumulative renting costs. This is the point at which your home equity and appreciation have overcome the upfront transaction costs of buying.

Should I factor in tax deductions for mortgage interest?

The calculator does not include mortgage interest deductions because the standard deduction ($27,700 for married couples in 2024) means only about 13% of filers itemize. If you do itemize, your true buying cost will be lower than calculated here. Consult a tax advisor for personalized analysis. The mortgage interest deduction is most valuable in the first years of the loan when interest payments are highest, and for higher-priced homes with larger mortgages.

What if I am unsure how long I will stay?

The break-even year is the key number. If you are fairly confident you will stay longer than the break-even point, buying likely makes financial sense. If your timeline is uncertain, the flexibility of renting (no selling costs, no maintenance, easy to move) has real value that this calculator does not capture. Consider a "worst-case" scenario: if you had to move in 2 years, could you absorb the loss? This risk analysis is often more important than the financial comparison itself.

Does the calculator include HOA fees?

HOA fees are not directly included in the buy scenario inputs, but you can factor them into your maintenance percentage or simply acknowledge that the buying total cost may be slightly higher if HOA fees are significant. In many markets, HOA fees are $200-$500/month, which should be considered when comparing renting to buying — especially in condos and planned communities.

What if home prices drop after I buy?

A market downturn shortly after purchase can leave you "underwater" (owing more than the home is worth). This calculator assumes steady annual appreciation, but actual returns are uneven. If you might need to sell within 3–5 years, a price drop could mean a significant loss. Stress-test by trying 0% or negative appreciation to see how long it would take to recover.
