Calculate your operating ratio and operating margin to measure operational efficiency. Compare against industry benchmarks and track year-over-year trends.
Try an example:
Formulas:
Operating Ratio = (COGS + OpEx) / Net Sales x 100
Operating Margin = 100% - Operating Ratio

The operating ratio is a financial metric that measures the proportion of a company's revenue consumed by operating costs. According to Investopedia, it is calculated by dividing total operating costs (COGS plus operating expenses) by net sales, then multiplying by 100 to express it as a percentage.
A lower operating ratio is generally better because it indicates that a smaller portion of revenue is being consumed by costs, leaving more for profit. The CFA Institute notes that the operating ratio is particularly useful for comparing companies within the same industry, as operating cost structures vary significantly across sectors.
The operating ratio and operating margin are complementary metrics that together always equal 100%. If your operating ratio is 75%, your operating margin is 25%. This relationship makes it easy to convert between the two metrics depending on your analytical preference. For a fuller view of operating earnings that excludes depreciation and amortization, pair this with operating earnings analysis using the EBITDA calculator.
Operating Ratio = (Operating Expenses + COGS) / Net Sales x 100
The complementary metric:
Operating Margin = 100% - Operating Ratio
Total revenue from sales minus returns, allowances, and discounts. This is the denominator that represents your total income from operations.
Direct costs of producing goods or services:
Indirect costs of running the business:
A software company has:
The company retains 35% of revenue as operating income, which is excellent for a software company.
Operating ratios vary dramatically by industry. Understanding typical ratios for your sector helps you benchmark performance and set realistic improvement targets.

The operating ratio and operating margin are two sides of the same coin. They measure the same operational efficiency but from opposite perspectives, and together they always sum to 100%.
(COGS + OpEx) / Revenue x 100
Operating Income / Revenue x 100
Example: If a company has an operating ratio of 80%, its operating margin is 20% (100% - 80% = 20%). This means 80% of revenue goes to operating costs, leaving 20% as operating income.

The operating ratio measures how much of each revenue dollar is consumed by operating costs. A lower ratio indicates better operational efficiency and higher profitability. Pair it with gross margin analysis to separate product economics from overhead.
Operating ratio and operating margin are complements: they always sum to 100%. If your operating ratio is 75%, your operating margin is 25%.
Industry context is critical. Airlines typically operate at 90-98% (2-10% margin), while software companies often achieve 55-75% (25-45% margin).
Track your operating ratio over time. Improving trends indicate better cost control or pricing power, while deteriorating trends signal margin compression.
Analyze expense breakdown to identify improvement opportunities. High COGS suggests supply chain optimization, while high operating expenses may require overhead reduction. For overhead-only benchmarking, compare against the operating expense ratio.
The operating ratio measures the proportion of a company's revenue consumed by operating costs (COGS plus operating expenses). According to Investopedia, it is calculated as (Operating Expenses + COGS) / Net Sales x 100. A lower operating ratio indicates greater operational efficiency, as it means the company retains more of each dollar of revenue as operating income.
A good operating ratio varies significantly by industry. Generally, a ratio below 75% is considered good, while below 60% is excellent. Airlines typically operate with ratios of 90-98%, while software companies may achieve 55-75%. Per the CFA Institute, comparing your ratio to industry benchmarks is more meaningful than using absolute thresholds.
Operating ratio and operating margin are complementary metrics that sum to 100%. Operating Ratio = (Operating Costs / Revenue) x 100, while Operating Margin = (Operating Income / Revenue) x 100. If your operating ratio is 75%, your operating margin is 25%. Both measure operational efficiency from different perspectives.
The Operating Expense Ratio (OER) measures only operating expenses as a percentage of revenue, excluding COGS. It is commonly used in real estate to evaluate property management efficiency. OER = Operating Expenses / Revenue x 100. A lower OER indicates better cost control of indirect operating costs.
Airlines have high operating ratios (typically 90-98%) due to their capital-intensive business model. According to IATA, airlines face massive costs including fuel (20-30% of expenses), labor, aircraft maintenance, airport fees, and depreciation. Even small revenue fluctuations can swing airlines between profit and loss.
You can improve your operating ratio by: 1) Reducing COGS through supplier negotiations or production efficiency, 2) Cutting operating expenses like rent, utilities, or administrative costs, 3) Increasing revenue without proportionally increasing costs, 4) Automating processes to reduce labor costs, 5) Improving inventory management to reduce waste. For cost-control playbooks and pricing strategies, see the Valuefy blog.
COGS includes direct costs of producing goods or services: raw materials, direct labor, and manufacturing overhead. Operating expenses are indirect costs of running the business: rent, utilities, salaries (non-production), marketing, insurance, and depreciation. The distinction affects gross margin (after COGS) vs. operating margin (after both).
The operating ratio directly impacts profitability. A lower ratio means higher operating income, which then covers interest, taxes, and generates net profit. However, net profit also depends on non-operating items. According to Corporate Finance Institute, tracking operating ratio trends helps identify operational efficiency changes before they impact the bottom line.
Operating ratios vary dramatically across industries due to fundamentally different cost structures. Airlines typically carry operating ratios of 90-98% because fuel (20-30% of costs), labor, and maintenance are all enormous fixed expenses — even a 2-3% revenue dip can erase profitability. Retail companies generally run 85-92%, with grocers at the high end and specialty retailers somewhat lower. Software and SaaS companies are the most efficient, typically achieving 55-75% operating ratios because marginal distribution costs are near zero. Professional services firms (consulting, law, accounting) range from 65-85%, while manufacturers vary widely from 75-90% depending on automation level. Always compare your ratio against direct industry peers rather than a universal benchmark.
Business analysts use operating ratio trends and peer comparisons to pinpoint inefficiency. A rising operating ratio over three or more consecutive quarters signals that costs are growing faster than revenue — a key red flag. Cross-departmental analysis helps isolate whether the driver is COGS (supply chain, procurement, pricing) or operating expenses (SG&A bloat, headcount expansion). Segment-level operating ratios reveal which product lines or geographies drag down overall performance. Year-over-year comparisons strip out seasonal noise. Analysts also calculate the ratio on a trailing-twelve-month (TTM) basis for more stable trend signals. When benchmarking against public peers using SEC filings, adjusting for non-recurring items ensures an apples-to-apples comparison.
