Profitability metric

ROA (Return on Assets)

Measures how efficiently a company uses its asset base to produce profit.

Formula

ROA = Net Income / Average Total Assets x 100%

Worked example$1.2 billion of net income divided by $20 billion of average assets gives ROA of 6%.

Calculation steps

  1. Find net income: $1.2 billion.
  2. Average beginning and ending assets to get $20 billion.
  3. Divide and multiply by 100 to get 6%.

How to interpret it

A higher ROA generally indicates more profit generated per unit of assets.

Industry context

ROA is especially useful for banks, manufacturers, and other asset-intensive businesses, but expected levels vary by industry.

Common mistakes

  • Use average assets when possible.
  • Do not compare asset-light and asset-heavy models directly.
  • Consider write-downs that may shrink the asset base.
