About Rent vs Buy: Price-to-Rent Ratio

Use this ratio to compare the price of a home with the annual rent of a comparable property. It is a screening calculation, not a recommendation to buy or rent. The rent total assumes the monthly rent never changes.

The Math Behind It

Price-to-rent ratio = home price ÷ (12 × monthly rent). A $400,000 home and $2,500 monthly rent produce a ratio of 13.33; ten years of unchanged rent total $300,000. This does not show the cost of ownership or a financial break-even date. A full scenario must include mortgage rate and amortization, down payment, closing and selling costs, property tax, insurance, maintenance, association fees, rent increases, home-price changes and the after-tax return on alternative investments. Tax treatment and housing costs depend on location and circumstances. Vary uncertain assumptions and compare equivalent homes; there is no universal ratio threshold that decides which option is better.

Formula Reference

Price-to-Rent Ratio

Home price / (monthly rent × 12)

Variables: Use comparable properties and the same currency.

Worked Examples

Example 1: Compare a $400,000 home with $2,500 rent

Monthly rent stays unchanged for 10 years.

Step 1:Annual rent = $2,500 × 12 = $30,000.
Step 2:Price-to-rent ratio = $400,000 ÷ $30,000 = 13.33.
Step 3:Flat-rent total = $30,000 × 10 = $300,000.

A 13.33 ratio and $300,000 rent total; neither figure establishes the cheaper housing choice.

Common Mistakes & Tips

  • !Comparing dissimilar properties.
  • !Treating rent spending as a full net-wealth comparison.
  • !Assuming a ratio proves buying is preferable.
