What Is ROA?

ROA (Return on Assets, 총자산이익률) is a key profitability ratio that shows how efficiently a company uses its assets to generate net income.
In simple terms, it tells you how much profit a company earns from every dollar (or won) of assets it owns.

Why ROA Matters

ROA helps investors and analysts evaluate how well management is using company assets to create profits.

  • High ROA: The company is using its assets efficiently to generate strong returns.

  • Low ROA: Assets may be underutilized or profitability is weak relative to asset size.

It’s especially useful when comparing companies in the same industry, since asset intensity differs by sector.

How to Calculate ROA

Formula:
ROA = (Net Income ÷ Total Assets) × 100

Example:
If a company has $10 million in net income and $200 million in total assets,
then ROA = (10 ÷ 200) × 100 = 5%.

This means the company earns $0.05 of profit for every $1 of assets.

Interpreting ROA Results

  • Above Industry Average: Shows strong operational efficiency.

  • Below Industry Average: May indicate excessive asset base or weak profitability.

  • Year-over-Year Increase: Suggests improving management performance.

However, ROA alone doesn’t reveal financing structure (debt vs equity), so it’s often used together with other ratios.

Relationship with ROE and Other Ratios

  • ROE (Return on Equity): Focuses on profits relative to shareholders’ equity, while ROA looks at total assets.

  • ROIC (Return on Invested Capital): Evaluates how efficiently total capital is used.

  • Asset Turnover Ratio: Helps explain why ROA is high or low by showing revenue generated per asset.

Together, these ratios offer a full view of profitability and asset utilization.

Conclusion

ROA (Return on Assets) is one of the most important indicators of financial performance.
It measures how effectively a company’s assets are being turned into profits — a vital insight for investors, managers, and analysts seeking sustainable growth.
