Capital Budgeting: Debt vs. Equity Financing and EPS Impact
This paper examines the capital budgeting decision facing a firm that must choose between debt and equity financing for a $1,000,000 project. Using a firm with 5,000,000 shares outstanding at $1.25 per share as a base case, the analysis calculates earnings per share and price/earnings ratios under each financing scenario, assuming perfect capital markets with no arbitrage or dilution. The paper demonstrates that debt financing produces a higher EPS ($0.03) but a lower P/E ratio (41.66×), while equity financing produces a lower EPS ($0.0258) but a higher P/E ratio (48.44×), and explains what these outcomes mean for shareholders and future growth prospects.

What makes this paper effective
- Presents a clear, worked numerical example that grounds abstract financial concepts in concrete calculations, making the comparison between debt and equity immediately tangible.
- Maintains a focused analytical thread throughout — every calculation ties back to the central question of how financing choice affects EPS and P/E ratio.
- Acknowledges the simplifying assumption of perfect capital markets and notes real-world deviations (dilution, interest charges) in the conclusion, demonstrating intellectual honesty without undermining the core analysis.
Key academic technique demonstrated
The paper uses comparative scenario analysis: two mutually exclusive financing options are evaluated side by side using identical base figures, isolating the single variable (debt vs. equity) to reveal its direct impact on EPS and P/E. This controlled comparison is a standard technique in corporate finance coursework for demonstrating capital structure effects.
Structure breakdown
The paper opens by defining the problem and the firm's existing capital structure. It then walks through the equity financing scenario step by step, followed by the debt financing scenario in the same format. A comparative section interprets the two sets of results and discusses growth-prospect implications. The conclusion broadens the lesson to real-world capital structure management. The logical progression mirrors the format of a finance case analysis.
Introduction to the Capital Budgeting Decision
A firm is faced with the decision of how to finance a new project. The project will cost $1,000,000. The current capital structure of the firm consists of 5,000,000 shares at a price of $1.25 per share, for a total equity value of $6,250,000. If the company issues equity, the share price will remain the same but more shares will be issued, increasing the total equity in the firm. If debt is issued, the equity remains unchanged but $1,000,000 in debt will be added. The decision will therefore affect the firm's capital structure and its earnings per share. This paper analyzes how earnings per share in particular is affected by the capital budgeting decision.
Equity Financing: Share Issuance and EPS Calculation
Given perfect capital markets, it is assumed that the company will issue new shares at the same price as the current shares — $1.25 per share. There will be no arbitrage opportunities and no dilution in this example. Financing the $1,000,000 project through a share issue would require the company to sell 800,000 shares, as shown below:
$1,000,000 ÷ $1.25 = 800,000 shares
The new total number of shares outstanding will be the current total plus the newly issued shares:
5,000,000 + 800,000 = 5,800,000 shares
The earnings per share next year will reflect expected earnings of $150,000 divided by the total shares outstanding of 5,800,000:
$150,000 ÷ 5,800,000 = $0.0258 per share
The firm's price/earnings ratio will reflect the share price divided by the expected earnings per share. With a share price of $1.25 and expected earnings per share of $0.0258, the forward P/E ratio under the equity financing scenario is:
$1.25 ÷ $0.0258 = 48.44 times
Debt Financing: EPS and Price/Earnings Ratio
If the firm issues debt instead, the forward price/earnings ratio is calculated in the same manner but with different figures. The expected share price remains $1.25. Since no new shares are issued, the equity of the firm is still 5,000,000 shares × $1.25 = $6,250,000, and the share price is unchanged.
The earnings per share, however, will differ. Because no new shares have been issued, the number of outstanding shares remains at 5,000,000. The EPS calculation for the debt financing scenario is therefore:
$150,000 ÷ 5,000,000 = $0.03 per share
The price/earnings ratio under the debt financing scenario is accordingly:
$1.25 ÷ $0.03 = 41.66 times
Conclusion: Capital Structure and Shareholder Impact
As this example illustrates, the decision between debt and equity financing has specific ramifications for shareholders. Perfect capital markets were assumed, but in many real-world cases, an additional debt issue will result in dilution of the value of existing shares. Debt also carries costs in the form of interest charges that reduce earnings. By stripping away these ancillary effects, this example isolates the most basic and direct impacts on earnings and the P/E ratio arising from the choice between debt and equity.
The use of debt allows for higher earnings per share figures, but if the share price remains static, the P/E ratio will be reduced. The use of equity produces a lower earnings per share figure, which in turn yields a higher P/E ratio. It is important that a company always examine the impacts of new share issues or new debt issues on its capital structure and its current shareholders. The firm must be able to continue attracting capital, so understanding how new project financing affects existing owners is imperative. In summary: debt issues increase EPS while decreasing the P/E ratio, and equity issues decrease EPS while increasing the P/E ratio.
