Rent vs Buy Calculator

How to Use This Rent vs Buy Calculator

Enter your current or expected monthly rent and annual rent increases

Input the home price, down payment percentage, and mortgage rate

Set your expected time horizon (how long you plan to stay)

Include assumptions for home appreciation and investment returns

Click Compare to see which option costs less over your timeframe

Example: Comparing $2,000/month rent (3% annual increases) versus a $400,000 home with 20% down at 6.5%, over 7 years: Total rent cost is $180,000, while net buying cost is $165,000 after equity. Buying saves $15,000 in this scenario.

Tip: The time horizon matters enormously. Short stays (under 5 years) often favor renting due to buying transaction costs.

Why Use a Rent vs Buy Calculator?

The rent versus buy decision involves comparing all costs, not just monthly payments, over your expected time in the home.

Determine if you'll stay long enough to justify buying costs

Compare total cost of ownership versus renting over time

Factor in home appreciation and equity building

Account for the opportunity cost of your down payment

Evaluate different housing markets and price-to-rent ratios

Make data-driven decisions rather than following conventional wisdom

Understanding Your Results

The calculator compares true total costs including opportunity costs and equity gains.

Buying saves 20%+

Meaning: Clear financial advantage to owning

Action: Buy if you value stability and can afford the down payment

Within 10% either way

Meaning: Financially similar options

Action: Let lifestyle preferences and flexibility needs guide your decision

Renting saves 15%+

Meaning: Renting is more cost-effective

Action: Rent and invest the down payment difference for potentially better returns

Note: This analysis assumes you invest the difference when renting. Not investing eliminates renting's opportunity cost advantage.

About Rent vs Buy Calculator

The rent versus buy decision is more complex than comparing monthly payments. Buying includes mortgage interest, property taxes, insurance, maintenance, and opportunity cost of the down payment. Renting includes monthly rent plus the investment returns you could earn on money not spent on a down payment. Home appreciation builds equity but isn't guaranteed. Transaction costs (closing costs, agent fees) can total 8-10% of home value, requiring several years of appreciation to break even. Estimate your potential monthly payments with our calculate a home loan, and use our estimate long-term investment gains to see how your down payment could grow if you continued renting.

Formula

Net Buying Cost = Down Payment + Mortgage Payments + Expenses - Equity Gained

Compare this to: Total Rent + (Down Payment × Investment Return) to find which option costs less.

Current Standards: The price-to-rent ratio (annual rent × 20 should roughly equal home price) suggests when buying becomes favorable. Many markets in 2026 have ratios above 25, favoring renting.

Frequently Asked Questions

How long should I plan to stay before buying makes sense?

Generally 5-7 years minimum. Buying costs (closing costs, agent fees) total 8-10% of home value. With 3-4% annual appreciation, you need several years just to break even on transaction costs. The shorter your stay, the more renting makes sense.

Should I count the mortgage payment as building equity?

Only the principal portion builds equity; interest does not. In early years, most payment goes to interest. On a $320,000 loan at 6.5%, only $670 of a $2,023 monthly payment builds equity in year one. The rest ($1,353) is interest cost.

What investment return should I assume for renting savings?

Use a realistic long-term stock market return of 7-8% for aggressive investors, or 5-6% for a balanced portfolio. Using unrealistic returns (10%+) unfairly biases the comparison toward renting. The down payment amount significantly impacts this comparison.

Does this account for tax benefits of homeownership?

The mortgage interest deduction only helps if you itemize deductions. With the 2026 standard deduction at $30,000+ for couples, many homeowners no longer itemize. State/local tax deductions are capped at $10,000. Tax benefits are smaller than many assume.

What about the emotional value of homeownership?

Ownership provides stability, freedom to modify your home, and fixed housing costs (except taxes/insurance). These have real value but aren't captured in financial calculations. If the numbers are close, lifestyle factors can legitimately tip your decision toward buying.
