How to Calculate Cap Rate in 3 Steps

Cap rate strips out financing so you can compare any two properties on equal footing.

  1. 1

    Calculate Net Operating Income (NOI)

    Start with gross rental income. Subtract vacancy (typically 5–8%), then subtract all operating expenses: property taxes, insurance, maintenance, management, and reserves. Do not subtract mortgage payments — NOI is a pre-financing number.

  2. 2

    Divide by Purchase Price

    Cap Rate = NOI ÷ Price. A $300,000 property with $21,000 NOI has a 7.0% cap rate. This tells you the property yields 7 cents of income for every dollar of value — regardless of how you finance it.

  3. 3

    Compare & Set Price Targets

    Use cap rate to compare properties in different markets. Or work backwards: Price = NOI ÷ Target Cap Rate. If you need a 7% return, and NOI is $21,000, don't pay more than $300,000.

Why Cap Rate Is the First Number Investors Check

The capitalization rate (cap rate) is the most widely used metric for comparing investment properties. It answers a simple question: "How much income does this property produce relative to its price?"

Cap Rate Formula

NOI ÷ Property Price

Net Operating Income divided by the property's purchase price or current market value.

NOI Formula

Gross Income − Vacancy − Operating Expenses

Annual income after vacancy and expenses, but before mortgage payments.

Value from Cap Rate

NOI ÷ Target Cap Rate

Work backwards to find what price yields your target return.

Cap rate only works if your NOI estimate is honest. If you understate vacancy or leave out real operating expenses, the cap rate will look stronger than the deal actually is. For a deeper breakdown of what belongs in NOI, read What Is NOI in Real Estate?.

Cap Rate Benchmarks by Property Type

Property TypeTypical Cap RateRisk Level
Class A Multifamily (major metro)4.0–5.5%Lower
Single Family Rental5.0–7.0%Moderate
Small Multifamily (2–4 units)5.5–8.0%Moderate
Value-Add / Secondary Market7.0–10.0%Higher
Self-Storage / Industrial6.0–9.0%Varies

Cap rate is a starting point, not the whole story. A full analysis also considers cash flow after financing, DSCR, rent growth projections, and downside scenarios — all of which DealForge calculates automatically.

When Cap Rate Can Mislead You

  • Two properties can have the same cap rate but very different risk profiles — a Class A apartment vs. a rural self-storage facility.
  • Cap rate doesn't account for capital expenditures. A high cap rate deal may need a new roof next year.
  • In appreciation markets, investors accept lower cap rates betting on value growth — which cap rate ignores.
  • Always pair cap rate with cash-on-cash return (financing impact) and DSCR (loan safety) for a complete picture.

Frequently Asked Questions

What is NOI in real estate?

NOI stands for Net Operating Income. It is the property’s income after vacancy and operating expenses, but before mortgage payments and taxes. Cap rate starts with NOI, so if your NOI estimate is wrong, your cap rate is wrong too.

What is a cap rate?

Cap rate (capitalization rate) measures a property’s annual net operating income as a percentage of its purchase price. It shows what return you’d earn if you paid all cash — no financing. Formula: NOI ÷ Property Price.

What is a good cap rate for rental property?

It depends on the market and property type. In 2026, most residential investors target 5–8% cap rates. Class A properties in major metros trade at 4–5%. Value-add or smaller market deals often hit 7–10%. Higher cap rate = higher income yield, but usually higher risk.

How is cap rate different from cash-on-cash return?

Cap rate ignores financing — it measures the property’s unlevered return. Cash-on-cash return factors in your mortgage, showing the return on your actual cash invested. A deal can have a 6% cap rate but a 10% cash-on-cash return if leverage is favorable.

Does cap rate include mortgage payments?

No. Cap rate is calculated before financing costs. It only considers NOI (income minus operating expenses) divided by property price. This makes it useful for comparing properties regardless of how they’re financed.

Can cap rate be negative?

Yes, if operating expenses exceed income (negative NOI). This can happen with vacant properties or heavy renovation projects. A negative cap rate means the property loses money before any financing costs.
