### Operating Ratio Formula & Example

Definition: Operating ratio is the ratio of cost of sales plus operating expenses to net turnover. It is an indicator of the operational efficiency of a business, a low operating ratio indicates high operating profit.

Formula:
Operating Ratio = [(Cost of sales + Operating expenses) / Net sales] * 100%

Example 1:
Calculate operating ratio given the following figures:
Cost of sales is \$300,000, other operating expenses are \$50,000, and net sales is \$1,000,000.

Solution:
Operating Ratio = [(300,000 + 50,000) / 1,000,000] * 100% = 35%

Example 2:
The following information relates to Peter Ltd. for the year ended 31 December 2010:
Rental \$30,000
Electricity \$3,000
Total sales \$89,000
Salaries and wages \$12,000
Postage \$600
Cost of goods sold \$9,400
Sales returns \$1,000

Calculate the operating ratio.

Solution:
Overhead expenses = Rental + Electricity + Salaries and wages + Postage = 30,000 + 3,000 + 12,000 + 600 = \$45,600
Net sales = 89,000 - 1,000 = \$88,000

Operating Ratio = [(9,400+ 45,600) / 88,000] * 100% = 62.5%
