How it works

Capitalisation rate expresses a property net operating income as a percentage of its value, giving the unlevered yield. It is how commercial real estate is priced, and rearranging it converts an income figure into a valuation.

Formula
Cap rate = NOI / Property value × 100
Value = NOI / Cap rate
Variables
  • NOInet operating income: effective gross income less operating expenses
  • Property valuepurchase price or current market value
Worked example
Inputs: Gross rent $132,000, 5% vacancy, operating expenses $41,400, price $1,200,000
  1. Vacancy loss: 132,000 × 0.05 = 6,600
  2. Effective gross income: 132,000 − 6,600 = 125,400
  3. NOI: 125,400 − 41,400 = 84,000
  4. Cap rate: 84,000 / 1,200,000
Result: 7.0% cap rate
Notes
  • NOI excludes mortgage payments, depreciation, and income tax. Including debt service is the single most common error and makes properties look artificially cheap.
  • Include a capital-expenditure reserve (commonly 5-10% of gross rent) in expenses. Sellers routinely omit it to inflate the advertised cap rate.
  • Cap rate moves inversely to price. At fixed NOI, a rate rising from 6% to 7% cuts value by about 14%, which is how rate cycles reprice entire portfolios.
  • Rates are only comparable within the same market and asset class. A 4% cap in a prime metro and an 8% cap in a secondary market are pricing different risk, not different quality of deal.
