Return on Assets (ROA) Calculator

How it is calculated

The tool divides net income by total assets and multiplies by 100: ROA % = net income ÷ total assets × 100. Both inputs are money amounts in the same currency and for the same period, for example one fiscal year's net income against the year's total assets. The result is shown as a percentage. If total assets are zero or negative, no result is returned because the ratio is meaningless. Net income can be negative, which gives a negative ROA (a loss relative to assets). The tool uses the single total-assets figure you enter; it does not average opening and closing balances for you.

Common mistakes

• Using revenue or operating profit instead of net income. ROA here is net income over total assets.
• Entering net income for a quarter but total assets as a year-end figure; the periods should match, or annualise the income first.
• Entering equity instead of total assets. Equity gives return on equity, which is a different and usually higher number.
• Entering the two amounts in different units, such as income in thousands and assets in full units.
• Comparing ROA across very different industries. Asset-heavy businesses naturally show lower ROA than asset-light ones.
