Return on assets measures profit against everything a business owns — not just the equity the owners have put in, but debt-financed assets too.
How it works
Net income divided by total assets. Comparing ROA against this site’s ROE calculator for the same business shows how much of the return comes from leverage (debt-financed assets) rather than the equity base alone.
How to use this calculator
- Enter net income and total assets.
A worked example
Net income $120,000 against total assets $1,000,000 → 120,000 ÷ 1,000,000 × 100 = 12% ROA.
Net income $50,000 against total assets $2,000,000 → 2.5% ROA — a much larger asset base producing a lower return, despite a real profit.
What the variables mean
| Variable | Meaning |
|---|---|
| Net income | Profit after all expenses and taxes |
| Total assets | Everything the company owns, from cash to equipment |
Edge cases worth knowing
A bigger asset base doesn’t mean better performance. ROA measures how efficiently assets generate profit, so a smaller, leaner company can post a higher ROA than a much larger one with the same net income.
Zero total assets makes the ratio undefined — there’s nothing to divide net income by, so the calculator returns no result.
Frequently asked questions
Why is ROA usually lower than ROE?
Total assets are usually larger than equity alone, since assets are financed partly by debt — dividing the same net income by a bigger number gives a smaller ratio.
Is ROA comparable across industries?
Less so than within one — asset-heavy industries naturally show lower ROA than asset-light ones for a similar level of actual profitability.
