Operating Margin
Operating margin is a profitability ratio that measures what percentage of each revenue dollar remains after covering all operating costs -- cost of goods sold, labor, rent, and overhead -- but before interest expense and income taxes. It is calculated as operating income (EBIT) divided by total revenue, expressed as a percentage. Unlike gross margin, it captures the full cost of running the business day-to-day. Investors and lenders use operating margin to compare operational efficiency across companies or periods regardless of financing structure or tax position.
Problem & Application
Formula: Operating Margin = (Operating Income / Revenue) x 100. Example: a 40-site RV park generates $600,000 in annual revenue. Operating costs -- utilities, labor, maintenance, insurance, and software -- total $420,000, producing operating income of $180,000. Operating margin = 30%. A competing park with the same revenue but $480,000 in costs has a 20% operating margin. The 10-point gap signals either a cost structure problem or a pricing advantage. For STR and campground operators, typical margin pressure comes from labor during peak season and utility costs in extreme climates. Tracking operating margin monthly, rather than only at year-end, lets owners see exactly which months erode profitability and whether rate increases are flowing through or being consumed by rising costs.
In Short
Operating margin is a critical indicator of operational efficiency and profitability, helping businesses assess their ability to generate income from core activities.
