How to Calculate Cap Rate on a Rental Property (2026 Guide)
The Capitalization Rate (Cap Rate) is the foundational metric real estate investors use to evaluate property profitability, compare multi-family assets, and determine whether a deal generates sufficient unlevered cash flow. Learn how to calculate cap rate step-by-step with real-world 2026 numbers.
Cap Rate = (Net Operating Income ÷ Property Value) × 100
Where Net Operating Income (NOI) = Gross Annual Rent − Vacancy − Operating Expenses (Property Taxes, Insurance, Maintenance, Management).
Note: Mortgage debt service is excluded.
Step-by-Step Worked Example: Single-Family Rental
Consider an investor evaluating a residential single-family rental property with a purchase price of $400,000:
- Determine Gross Scheduled Rent: Property rents for $3,000/month × 12 months = $36,000.
- Subtract Vacancy Allowance (5%): $36,000 × 0.05 = -$1,800. Effective Gross Income = $34,200.
- Itemize Operating Expenses:
- Property Taxes: $4,800/yr
- Hazard & Landlord Insurance: $1,600/yr
- Property Management (8%): $2,736/yr
- Repairs & Maintenance Reserve: $2,000/yr
- Total Operating Expenses = $11,136
- Compute Net Operating Income (NOI): $34,200 − $11,136 = $23,064.
- Apply the Cap Rate Formula:
Cap Rate = ($23,064 ÷ $400,000) × 100 = 5.77%
What Is a Good Cap Rate in 2026?
There is no universal "good" cap rate because return always reflects risk, liquidity, and growth potential. Here is how institutional investors benchmark cap rates across the US in 2026:
| Cap Rate Range | Risk Profile | Typical US Markets | Investment Strategy |
|---|---|---|---|
| 3.5% – 5.5% | Low Risk / Trophy | Seattle, San Diego, NYC, Boston, Orange County | Capital preservation and long-term land appreciation |
| 5.5% – 7.5% | Moderate / Balanced | Dallas, Atlanta, Charlotte, Phoenix, Tampa, Columbus | Balanced mix of solid cash flow and economic population growth |
| 7.5% – 10.0%+ | Higher Cash Flow | Cleveland, Memphis, Detroit, Birmingham, Indianapolis | Immediate high cash yield; lower expectation of capital gains |
Cap Rate vs. Cash-on-Cash Return: The Critical Distinction
Many novice investors confuse Cap Rate with Cash-on-Cash Return:
- Cap Rate (Unlevered): Evaluates property yield assuming 100% cash purchase. Use it to compare two properties independently of financing.
- Cash-on-Cash Return (Levered): Measures annual pre-tax cash flow against actual equity cash invested out of pocket. Factors in your mortgage interest rate, down payment, and closing costs.
