How to Use Internal Growth Rate Calculator?
- Enter Retained Earnings: Input the amount of earnings retained in the company. This figure represents funds available for reinvestment.
- Input Net Income: Provide the company’s net income. It helps calculate the retention ratio, a key component of the internal growth rate.
- Input Total Equity: Enter the total shareholder’s equity. This value is essential for determining the return on equity (ROE).
- Calculate: Press the calculate button. The tool will compute the internal growth rate, revealing the maximum sustainable growth percentage.
When interpreting results, ensure that all inputs are accurate to avoid misleading outcomes. Common mistakes include using outdated financial statements or incorrect figures, which can skew the results.
Backend Formula for the Internal Growth Rate Calculator
The internal growth rate formula is:
Internal Growth Rate = (Retention Ratio * Return on Equity) / (1 - (Retention Ratio * Return on Equity))
Breaking it down:
- Retention Ratio: The portion of net income retained in the company. Calculated as Retained Earnings divided by Net Income.
- Return on Equity (ROE): Measures profitability relative to shareholder’s equity. Calculated as Net Income divided by Total Equity.
Consider a company with a retention ratio of 0.6 and an ROE of 0.15. Plugging these into the formula gives an internal growth rate of approximately 9.68%. This figure represents the company’s sustainable growth rate without additional financing. Variations in the formula might include adjustments for extraordinary items or one-off events that affect net income.
Step-by-Step Calculation Guide for the Internal Growth Rate Calculator
- Calculate the Retention Ratio: Divide Retained Earnings by Net Income.
- Determine the ROE: Divide Net Income by Total Equity.
- Apply the Internal Growth Rate Formula: Use the retention ratio and ROE in the internal growth formula mentioned earlier.
Example 1: A company has retained earnings of $200,000, net income of $500,000, and total equity of $1,000,000. The retention ratio is 0.4, ROE is 0.5, and the internal growth rate is 28.57%.
Example 2: If retained earnings are $100,000, net income $300,000, and total equity $800,000, the retention ratio is 0.33, ROE is 0.375, and the internal growth rate is 14.29%.
To avoid manual calculation errors, ensure accurate input data, and double-check calculations for consistency.
Expert Insights & Common Mistakes
Experts emphasize the importance of using updated financial statements for accurate calculations. Additionally, understanding the limitations of the internal growth rate, such as its reliance on past performance, is crucial.

Internal Growth Rate Case Study Example
Consider a fictional company, “Tech Innovations,” looking to expand its market presence. With retained earnings of $150,000, net income of $400,000, and total equity of $900,000, they calculate an internal growth rate of 20.83%. This growth rate suggests they can expand without external financing.
In an alternative scenario, if Tech Innovations considers a major acquisition, they might reevaluate their internal growth rate post-acquisition to determine if external funding becomes necessary. This flexibility showcases the calculator’s versatility in various business contexts.
