Return on Net Assets (RONA)

Return on Net Assets (RONA) is a financial metric used to evaluate a company’s operational efficiency and profitability. It measures how effectively a company uses its net assets to generate income. Net assets, in this context, typically refer to the total assets of a company minus its total liabilities.

The formula for RONA is:

RONA = Net Operating Income / Net Assets


  • Net Operating Income is the operating profit of a company, usually found as Earnings Before Interest and Taxes (EBIT).
  • Net Assets is the total assets minus total liabilities.

RONA provides insight into how well a company’s core operations utilize its assets to produce profit, minus the financial structure (like debt). A higher RONA indicates a company is effectively using its assets to generate value.

Benefits of RONA:

  • Operational Efficiency: RONA focuses on operating income, making it a direct measure of the efficiency of a company’s core business operations.
  • Comparative Analysis: It’s a standard measure that can be used to compare the operational efficiency of different companies, even if they belong to different sectors.
  • Asset Utilization Insight: It sheds light on how effectively a company is using its net assets to produce income.

Limitations of RONA:

  • Varying Accounting Practices: Differences in accounting practices across companies or sectors might affect the comparison.
  • Ignores Financial Structure: Since RONA focuses on net assets and not the financial structure (like the influence of debt), it may not provide a complete picture of a company’s overall profitability or risk.

To get a comprehensive understanding of a company’s performance, RONA should be used in conjunction with other financial metrics.

Example of Return on Net Assets (RONA)

Let’s use a fictional company named ABC Manufacturing to illustrate the concept of Return on Net Assets (RONA).

ABC Manufacturing Financials:

  • Total Assets: $10,000,000
  • Total Liabilities: $4,000,000
  • Earnings Before Interest and Taxes (EBIT): $800,000

Using the provided information, we can compute the Net Assets and then RONA.

  • Calculate Net Assets:
    Net Assets = Total Assets − Total Liabilities
    Net Assets = $10,000,000 – $4,000,000
    Net Assets = $6,000,000
  • Calculate RONA:
    RONA = Net Operating Income (EBIT) / Net Assets
    RONA = $800,000 / $6,000,000
    RONA = 0.1333 or 13.33%


The RONA for ABC Manufacturing is 13.33%. This means that for every dollar of net assets ABC Manufacturing owns, it generates an operating profit of approximately 13.33 cents before paying interest and taxes.

For an investor or manager, this metric alone might not give a full understanding of the company’s performance. They would need to compare this RONA with industry benchmarks, competitors, and the company’s historical RONA to determine if 13.33% is a strong return in the given context.
