Operating Cash Flow Margin
Cash from operations divided by revenue. The cash-based counterpart to net profit margin — measures how much actual cash is generated per dollar of sales.
When to use: Use to cross-check net margin. Persistent gaps between CFO margin and net margin signal accruals — typically working-capital build (receivables growing faster than collections, inventory bloat) or aggressive revenue recognition. Sustainable businesses have CFO margin near or above net margin.

Real-Life Examples
Example 1: High-Quality Cash Generator
Cash from operations $500M, revenue $2,000M.
Given
Step-by-Step
25% OCF margin — strong cash generation. Compare to net margin: if net margin is 12% and OCF margin is 25%, the firm produces $0.13 of cash per dollar of sales beyond accounting earnings (driven by D&A add-back, deferred revenue, etc.).
Frequently Asked Questions
Accruals — non-cash items in net income. CFO adds back D&A and stock-based comp, then adjusts for working-capital changes. Subscription businesses with deferred revenue often show OCF margin meaningfully above net margin.
When net margin runs persistently above CFO margin. That gap indicates accounting earnings without cash backing — receivables ballooning, inventory growing faster than COGS, or aggressive revenue recognition. Many accounting frauds become visible first as a CFO-vs-net-income gap.
