Earnings per Share (EPS) Calculator

See exactly how much profit each common share is really earning, before and after potential dilution from options, convertibles, and other equity-linked instruments. Compare scenarios, sanity-check reported EPS, and connect the output directly to P/E, ROE, value creation, and buyback decisions.

Earnings Per Share (EPS) Calculator

Calculate basic and diluted earnings per share. Basic EPS = (Net Income - Preferred Dividends) / Weighted Average Shares. Diluted EPS adds convertible impacts and incremental shares for a more conservative view.

What is EPS (Earnings per Share)?

Earnings per Share measures how much profit is attributable to each common share after paying preferred dividends. It links the income statement to the share count and underpins core equity metrics like the P/E ratio, ROE, and market capitalization.

Analysts watch both basic EPS and diluted EPS to understand current profitability per share and the impact of potential dilution from stock options, RSUs, convertible bonds, and other equity-linked securities.

Formula

Basic EPS = (Net Income − Preferred Dividends) / Weighted Average Common Shares Outstanding
Diluted EPS = (Net Income − Preferred Dividends + After-tax Interest on Dilutive Debt + After-tax Convertible Preferred Dividends) / (Weighted Average Common Shares Outstanding + Dilutive Potential Common Shares)

Example

Assume a company reports net income of $1,200,000 and no preferred dividends, with 1,000,000 weighted average common shares outstanding.

  • Basic EPS = ($1,200,000 − $0) ÷ 1,000,000 = $1.20 per share.

Now assume the company has convertible debt that would add $30,000 of after-tax interest back to earnings and create 200,000 additional common shares if converted.

  • Adjusted earnings = $1,200,000 + $30,000 = $1,230,000.
  • Diluted share count = 1,000,000 + 200,000 = 1,200,000 shares.
  • Diluted EPS = $1,230,000 ÷ 1,200,000 ≈ $1.03 per share.

In this example, diluted EPS is lower than basic EPS, showing how potential conversion of equity-linked instruments reduces earnings per share and affects valuation, capital allocation, and incentive design.

How to Use the EPS Calculator (Earnings per Share)

This calculator lets you quickly compute both Basic EPS and Diluted EPS by entering net income, preferred dividends, share counts, and any dilutive securities. Use the view toggle at the top to switch between basic and diluted logic while keeping the same core inputs.

Choose the EPS view

  • At the top of the tool, select Basic EPS or Diluted EPS. Use Basic for a simple capital structure; switch to Diluted if there are options, warrants, convertible debt, or convertible preferred shares outstanding.

Enter profit and preferred dividends

  • In the Net Income field, input profit after tax for the period. In Preferred Dividends, enter any dividends on preferred stock that reduce earnings available to common shareholders.

Input share counts (and dilutive adjustments if needed)

    • For both views, fill in Weighted Average Shares with the weighted average common shares outstanding.

- In Diluted EPS view, also enter Additional Dilutive Shares (from in-the-money options, warrants, or convertibles) and add back any Interest (after tax) on convertible debt and Convertible Preferred Dividends that would no longer be paid after conversion.

Review the results panel

  • Scroll to the Results box: you’ll see Basic EPS, Diluted EPS, the weighted average share count, and total diluted shares. The top row “EPS (Selected View)” highlights the figure that matches the view you currently have selected.

Refine, compare, and reset

  • Adjust any inputs to test different capital-structure scenarios (e.g., more options exercised or different net income) and watch the EPS values update. Use Reset to clear all fields and start a fresh calculation; optional charts can be expanded if you want a visual view of EPS versus share count.

Frequently Asked Questions

How do I pull the right inputs for EPS from my financial statements?

Use net income and preferred dividends from the income statement, then take the weighted average common shares outstanding from the equity/share-capital note or EPS disclosure; plug them into the calculator as Net Income, Preferred Dividends, and Weighted Average Shares.

When should I look at basic EPS versus diluted EPS in this calculator?

Use Basic EPS if the company has only common shares or no meaningful dilutive securities; switch to Diluted EPS when there are options, warrants, convertible debt, or convertible preferred shares, because these can increase the share count and reduce earnings per share.

How does the calculator treat convertible bonds, options, and other dilutive securities?

In Diluted EPS view, you enter extra shares from in-the-money options, warrants, or convertibles as Additional Dilutive Shares and add back (after tax) any interest or preferred dividends that would disappear if those instruments converted; the tool then recomputes diluted EPS using the higher diluted share count.

What does my EPS result actually tell me, and what is a “good” EPS?

EPS shows how much profit is attributable to each common share; on its own there is no “good” number—compare your EPS (both basic and diluted) against the company’s past EPS, analyst expectations, and peers, or use it in valuation ratios like P/E to judge performance.
