Explorando o retorno sobre os ativos (ROA): uma métrica chave de desempenho

Understanding Return on Assets (ROA)

Return on Assets (ROA) is a powerful financial metric that investors and management use to gauge how efficiently a company utilizes its assets to generate profit. In simpler terms, ROA indicates the amount of net income generated by each dollar of assets held by the company.

The ROA Formula

The formula for calculating ROA can be broken down into two primary components:

• Net Income: This is the profit after all expenses, taxes, and costs have been deducted. It is typically measured in USD.
• Total Assets: This includes everything the company owns that has value, such as cash, inventory, property, and equipment. It is also measured in USD.

The formula is:
ROA = (Net Income / Total Assets) × 100
The result is expressed as a percentage.

Example Calculation

Let's say Company A has a net income of $200,000, and its total assets are worth $2,000,000. Using the ROA formula:
ROA = ($200,000 / $2,000,000) × 100 = 10%
This means Company A generates a 10% return on its assets.

Input Parameters

• Net Income: Measured in USD, representing the company's profit after all expenses.
• Total Assets: Measured in USD, representing the company's total asset value.

Output

The output of the ROA formula is a percentage that represents the efficiency of asset utilization by the company.

Data Validation

Input values must be positive numbers. Otherwise, the function should return an error message indicating invalid input values.
