Operating margin

Operating margin is the practice of operating income as a percentage of revenue, capturing profitability after operating expenses but before interest and taxes. For operating margin, the useful boundary is the driver, assumption, owner, time period, and decision the model is meant to support.

Why it matters

Understanding operating margin matters because planning only improves decisions when assumptions, drivers, owners, and time periods are explicit enough to revisit when actuals arrive. Pluvo links operating margin changes to the specific cost and revenue drivers behind them, separating one-time items from structural shifts.

In practice

Planning example
Teams use operating margin when a forecast, budget, or scenario needs an assumption that can be revisited. The finance team should know the driver, source data, owner, and period before using it in a model.

In practice, teams should define operating margin with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for operating margin separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

What is the difference between operating margin and net margin?

The boundary for operating margin differs from related terms by scope, source data, time period, and decision use.
