The cap rate formula

Cap Rate = Net Operating Income ÷ Property Value

NOI = gross annual rent minus operating expenses (taxes, insurance, management, maintenance, vacancy). It excludes the mortgage payment. Cap rate tells you the unlevered yield, the return if you owned the property free and clear. The default above, $18,000 NOI on a $350,000 property, works out to about 5.1%.

Cap rate ignores financing, while cash-on-cash includes it. At today's roughly 6.8% on a 30-year mortgage, a 5% cap rate property usually shows a negative cash-on-cash return after debt service, which is why so few markets cash-flow right now. See the difference →

What cap rate signals a cash-flow market

Cap rate is one of four inputs in our Investor Yield Index, which ranks 18 U.S. metros on live Zillow data. The strongest-ranked markets sit in the 7 to 8% range on gross cap rate, while the pricey coastal and Sun Belt metros land closer to 4%. Only the cheapest clear a 1.2 DSCR at current rates, so a high cap rate today is a relative signal, not a guarantee of positive cash flow.

Common questions

How is cap rate calculated?

Cap rate = net operating income ÷ property value. NOI is gross annual rent minus operating expenses (excluding the mortgage). It measures unlevered return.

What is a good cap rate?

It depends on market and risk. In 2026, 5 to 7% is common for solid single-family rentals, while 8% or more usually shows up only in cheaper, riskier markets. See what is a good cap rate for detail.

Does cap rate include the mortgage?

No. Cap rate is an unlevered metric, so it ignores financing. For your return with a mortgage, use cash-on-cash return instead.
