The Operating Expense Ratio (OER) is the ratio between the total operating expenses and the effective gross income.
Operating expenses are costs associated with the operation and maintenance of income producing properties. They include such items as property taxes, property management fees, insurance, wages, utilities, repairs and maintenance, supplies, advertising, attorney fees, accounting fees, trash removal, pest control, etc.
The following are not operating expenses: loan payments, personal property and capital improvements.
The effective gross income for a property is the actual yearly income from all sources. It is equal to the yearly gross rents possible plus other income such as laundry receipts, vending machines, parking fees, etc. less the yearly vacancy amount.
The operating expense ratio shows the percentage of a property's income that is being used to pay maintenance and operational expenses.
Operating Expense Ratio = Operating Expenses/Effective Gross Income
To establish a benchmark OER, you would calculate the operating expense ratio of similar income properties. You would then calculate the average OER for the properties.
The operating expense ratio is an indicator of how efficiently a property is being managed. The lower the operating expense ratio, the greater the profit for the investors.

If you are analyzing another person's proforma, or you are examining a prospectus for a real estate deal, it is very important that you read the document carefully and determine how the values of the financial statistics above are being calculated. For instance, values such as the Cap Rate may be determined from overly optimistic projections of the future rental income of a property.
You can "reverse engineer" the financial projections you receive from a prospectus and/or request the Excel (or other type of) spreadsheet a developer used to create their proforma.
