Is Renting Really Throwing Money Away? The Numbers Say Otherwise

Published March 18, 2026 · 5 min read · All Articles

"You're throwing money away on rent" is perhaps the most repeated — and most misleading — piece of financial advice. Here's why the math is more nuanced than the cliche suggests.

What Homeowners "Throw Away" Too

In the first 7 years of a 30-year mortgage, over 60% of your payment goes to interest — not equity. On a $400,000 mortgage at 6.75%, your monthly payment is $2,594. In year one, $2,250 goes to interest. Only $344 builds equity. You also pay property tax ($400-$800/month), insurance ($150-$200/month), maintenance (1% of home value = $333/month), and opportunity cost on your down payment. Total "thrown away" as a homeowner in year one: approximately $3,500/month. As a renter paying $2,000/month: you "throw away" $2,000. The renter throws away less money in this scenario.

The 5% Rule

A simple framework: multiply the home's value by 5%, divide by 12. If rent is less than this number, renting is cheaper. A $400,000 home: 5% = $20,000/year = $1,667/month. If you can rent a comparable place for under $1,667, renting wins financially. In expensive markets (SF, NYC, Seattle), this threshold often favors renting by a wide margin.

When Buying IS Better

Buying wins when: you'll stay 7+ years (recoup closing costs), you're in a market where rent exceeds the 5% rule, mortgage rates are significantly below 5%, you value stability and customization, and you have a 20% down payment (avoiding PMI). The decision should be based on your specific numbers, not a blanket rule.
