• Net operating income measures the profitability of an income-producing property before adding any financing or tax costs.

  • To calculate the NOI, subtract all operating expenses incurred in connection with the property from all income received from the property.
  • The operating expenses used in the NOI metric can be manipulated if the property owner delays or accelerates certain income or expense items.
  • NOI does not include capital expenditures.
  • The NOI will tell the property owner if renting the property is worth the cost of owning and maintaining it.
