How to Calculate Cap Rate

Net Operating Income (NOI)

Annual rental income minus operating expenses

NOI = Gross Rental Income - Operating Expenses
  • Gross rental income
  • Minus vacancy allowance
  • Minus operating expenses
  • Excludes mortgage payments

Property Value

Current market value of the property

Property Value = Purchase Price or Appraised Value
  • Purchase price
  • Appraised value
  • Market comparable value
  • Asset value for calculation

Cap Rate Formula

The relationship between income and value

Cap Rate = (NOI ÷ Property Value) × 100
  • Annual rate of return
  • Expressed as percentage
  • Before debt service
  • Pure income return

Cap Rate Calculation Example

123 Main Street, Cambridge, MA

Purchase Price:$500,000
Gross Annual Rent:$60,000
Vacancy Allowance (5%):-$3,000
Operating Expenses:-$12,000

Net Operating Income (NOI):$45,000
Capitalization Rate:9.00%

This property generates a 9.00% return on investment before considering financing costs.

Cap Rate FAQs

What's a good cap rate?

A "good" cap rate depends on your investment goals, risk tolerance, and market conditions. In Boston, investors typically target 6-8% cap rates for balanced risk-adjusted returns.

How does cap rate differ from cash-on-cash return?

Cap rate measures the property's income potential regardless of financing, while cash-on-cash return factors in your actual investment (down payment) and financing costs.

Can cap rates change over time?

Yes, cap rates fluctuate with market conditions. When interest rates rise or property values increase, cap rates typically rise. When interest rates fall or property values decrease, cap rates typically fall.
