Calculate NOI

NOI Formula

The standard mathematical formula for calculating Net Operating Income (NOI) is noted below. Note that you will first need to determine total property income and operating expense values first to input into calculation.

NOI = (Gross Operating Income1 + Other Income2)
– Operating Expenses

1. Gross Operating Income – A property’s gross operating income can be calculated as the property’s annual gross scheduled income, less vacancy loss (the amount of rental income that the property owner loses when the space is unoccupied by the tenants) and credit loss (the estimated dollar amount of lost rental income due to vacant units and non-payment of rent.)

2. Other Income – Income generated by a rental property other than rental unit income. Examples of other income can include revenue from parking, laundry, late-fees, application processing, and more.

3. Operating Expenses – Operating expenses include the costs of running and maintaining the building, including insurance premiums, legal fees, utilities, property taxes, repair costs, and janitorial fees.

NOI Definition
