An operating ratio approaching 100 percent means almost every unit of revenue is consumed by running costs, leaving nothing to absorb a bad quarter.
Railways, airlines and insurers report operating ratio as a headline figure, which makes it the natural basis for comparing companies within those sectors.
Operating Ratio = [(Cost of Goods Sold + Operating Expenses) ÷ Net Sales] × 100. It measures the proportion of sales revenue consumed by the day-to-day cost of running the business, before interest, tax, and non-operating items are considered.
Lower is better. A lower operating ratio means more of each sales dollar is left over as operating profit. A rising operating ratio over time is a warning sign — it means costs are growing faster than sales, even if revenue itself looks healthy.
Most established businesses run between 60% and 85%. Capital-light, high-margin businesses like software can be well below 50%. Capital-intensive, low-margin businesses like utilities, grocery retail, and airlines often run 85–95%, since their core operations have inherently thin margins even when well managed.
They are complements of each other (ignoring non-operating income): Operating Ratio + Operating Profit Ratio ≈ 100%. If the operating ratio is 78%, the operating profit ratio (operating margin) is roughly 22%. Use whichever framing is more intuitive — operating ratio for "how much of sales is consumed by costs," operating profit ratio for "how much is left over."
It excludes interest expense, taxes, and non-operating gains or losses (like a one-time asset sale). Two companies with identical operating ratios can have very different net profitability if one carries much more debt. Pair the operating ratio with the net profit ratio for the full picture.
Increase sales without proportionally increasing costs (operating leverage), renegotiate supplier contracts, automate manual processes, reduce overhead in underperforming areas, or improve inventory and supply-chain efficiency to lower COGS. Even small percentage-point improvements have an outsized effect because operating costs are typically the largest line item against revenue.
