📘 What Is a Stock Split?

A stock split is when a company divides its existing shares into multiple shares. The total value of your investment doesn't change – but the number of shares increases and the price per share decreases proportionally. For example, in a 2-for-1 split, every share you own becomes two shares, and the price is cut in half.

If you've ever wondered what happens to shares after stock split, our calculator shows the exact math. Companies usually split shares to make them more affordable for retail investors.

⚡ How Stock Splits Work (Forward vs Reverse)

Forward Stock Split (e.g., 2-for-1, 3-for-1)

You get more shares, each worth less. If you had 100 shares at $200 each, after a 2-for-1 split you'd have 200 shares at $100 each. Total value stays $20,000.

Reverse Stock Split (e.g., 1-for-2, 1-for-10)

You get fewer shares, each worth more. Companies do this to boost share price (e.g., to meet exchange listing requirements). Our stock split calculator adjustment tool free handles both types.

🧮 How to Calculate Stock Split (Step by Step)

Split Ratio Explained

The ratio tells you how many new shares you get for each old share. For a 2-for-1 split, ratio = 2. For a reverse 1-for-5 split, ratio = 0.2 (you get 1 new share for every 5 old shares).

Example Calculation (2-for-1 Split)

You own 100 shares at $200 each. Split factor = 2. New shares = 100 × 2 = 200. New price = $200 ÷ 2 = $100. Total value = 200 × $100 = $20,000 (unchanged). That's how to calculate 2 for 1 stock split.

Example Calculation (Reverse 1-for-5 Split)

You own 500 shares at $10 each. Split factor = 0.2. New shares = 500 × 0.2 = 100. New price = $10 ÷ 0.2 = $50. Total value = 100 × $50 = $5,000 (same).

Our stock split calculator with example does all this instantly – no manual math needed.
