OER is popular in the real estate industry, and it is a common ratio used while doing real estate analysis. In real estate analysis, the analysts judge the cost of operating a property with the income generated by the property.

How To Calculate?

To calculate the operating expense ratio for financial analysis purposes, it is necessary to know the formula used for the calculation.

Here’s the formula for operating expense ratio –

Operating Expense Ratio = Operating Expenses / Revenues

In the above formula we notice that there are two different variables, the operating expense and the revenues. The operating expense refers to any expense made in the business related to its day-to-day operations or its core business activity. They may not be directly incurred in the manufacturing of its products and usually include salaries, wages, marketing and advertising expense, insurance, repair, maintenance, travel and entertainment, etc.  

The revenue is the amount earned from the sale of its goods and services in the market within a particular time period. It is the income earned from the primary business operation.

Here are a few steps to operating expense ratio calculation calculation properly:

Determine the operating expense – This is the most important step where the operating expenses should be correctly identified after gathering the value of each of them for a specific period. Then make a total of all such expenses for the numerator of the formula.

Net revenue calculation – Then comes the collection of data for the denominator. The net revenue is the total amount generated from sales after deduction of sales return, discount and any allowances. This data should be related to the same time period as the operating expense.

Plugging in the values – The next step is to put the values in their respective places, divide the operating expense by the revenue to get the ratio.  

Example

Let’s take a simple example to illustrate the operating expense ratio formula.

• Operating expenses – $40,000
• Revenues – $400,000

Find out the OER of Onus Inc.

Using the operating expense ratio formula, we get –

• OER = Operating Expenses / Revenues
• Or, = $40,000 / $400,000 = 10%.

If we compare the ratio with the other companies in the same industry, we can interpret the OER correctly. Thus the above example not only shows in a very clear manner how to make the operating expense ratio calculation but also tells us that it can be used to make comparisons among companies.

Uses
