Cost of Internal Equity (%):

When companies finance their operations and growth, they can either raise capital externally or use internal sources like retained earnings. Retained earnings represent profits reinvested back into the company rather than paid out as dividends. But internal capital isn’t free—it carries an opportunity cost. That cost is known as the cost of internal equity.

The Cost of Internal Equity Calculator helps businesses and financial analysts estimate the expected return shareholders demand from the reinvestment of profits. It provides a quick, reliable way to compute this rate using the Dividend Discount Model (DDM), also known as the Gordon Growth Model.

Understanding the cost of internal equity is essential for financial planning, capital budgeting, and valuing equity properly.

Formula

The most common formula to calculate the cost of internal equity is the Gordon Growth Model:

Cost of Internal Equity (%) = (Dividend ÷ Market Price) × 100 + Growth Rate

Where:

• Dividend is the expected annual dividend per share.
• Market Price is the current price per share.
• Growth Rate is the expected constant growth rate of dividends.

This model assumes dividends grow at a steady rate indefinitely and helps estimate the rate of return shareholders require on reinvested earnings.

How to Use the Calculator

To use the Cost of Internal Equity Calculator, follow these steps:

1. Enter the Expected Dividend per Share – This is the forecasted annual dividend.
2. Enter the Current Market Price per Share – The price of the stock at the time of calculation.
3. Enter the Dividend Growth Rate – The annual percentage by which dividends are expected to grow.
4. Click “Calculate” – The calculator displays the cost of internal equity as a percentage.

This result is essential for evaluating whether internal financing is a cost-effective option.

Example

Let’s say a company is expected to pay a dividend of $2 per share next year, the stock is trading at $40, and dividends are projected to grow at 5% annually.

Using the formula:

Cost of Internal Equity = (2 ÷ 40) × 100 + 5 = 5% + 5% = 10%

So, the cost of internal equity is 10%. This is the return shareholders would expect if the company reinvests earnings instead of paying them out.

FAQs

1. What is the cost of internal equity?
It’s the rate of return shareholders expect from earnings retained in the business rather than distributed as dividends.

2. Why is this cost important?
It helps companies determine the cost of using retained earnings and compare it with external financing options.

3. How is it different from the cost of external equity?
External equity includes issuance costs and dilution, while internal equity uses retained earnings without transaction costs.

4. Is it always cheaper than external equity?
Usually yes, because there are no floatation or underwriting fees involved.

5. What model is used to calculate it?
The Dividend Discount Model (Gordon Growth Model) is the most common method.

6. Can this cost change over time?
Yes. It depends on market conditions, stock price, dividend expectations, and growth assumptions.

7. What happens if the company doesn’t pay dividends?
The model becomes invalid. Alternative models like CAPM (Capital Asset Pricing Model) are used instead.

8. What is the opportunity cost in this context?
It’s the return that shareholders could have earned elsewhere if profits were distributed rather than reinvested.

9. How accurate is this calculator?
Very accurate if the input values (dividends, price, growth) are realistic and based on reliable projections.

10. Is a high cost of internal equity bad?
Not necessarily. It means shareholders expect higher returns. The company should ensure investments meet or exceed that return.

11. What does a 10% cost of internal equity mean?
It means the business should earn at least a 10% return on reinvested profits to meet shareholder expectations.

12. Can it be used in investment decisions?
Yes. It’s a key component in calculating the Weighted Average Cost of Capital (WACC) and in capital budgeting.

13. Does inflation impact this calculation?
Yes, as inflation may influence both dividend growth expectations and required returns.

14. What if the market price drops significantly?
A lower market price increases the cost of internal equity, assuming dividends and growth remain unchanged.

15. Can it be negative?
In rare cases, such as when negative growth is expected, but it’s generally a positive percentage.

16. How is growth rate determined?
Through historical data, analyst forecasts, or company guidance on earnings/dividend growth.

17. Is this relevant for startups?
Not really. Startups often don’t pay dividends, so models like CAPM are more appropriate.

18. Should this cost be higher than debt?
Yes. Equity is riskier than debt for investors, so it carries a higher expected return.

19. Can I use this calculator for preferred shares?
No. Preferred shares have fixed dividends and should be evaluated differently.

20. How often should I update the calculation?
Quarterly or when major changes occur in dividends, market price, or growth outlook.
