The category of ratios used to evaluate profitability in comparable units. Profitability ratios let you compare a $5M business to a $50M business, or this year to last year, without absolute size masking the signal.
Definition
Profitability Ratio - any of several ratios that express profit as a percentage of something else - revenue (margins), assets (ROA), equity (ROE), or capital (ROIC). Used to standardize profitability for comparison.
Common uses
- Industry benchmarking - comparing yourself to peers in standardized terms
- Trend monitoring - watching ratios over time reveals what's changing
- Investment evaluation - investors look at ROE and ROA to assess capital efficiency
Watch out
A single profitability ratio can mislead. A high ROE achieved through aggressive leverage isn't the same as a high ROE from operational efficiency. Always look at multiple ratios together.
