📈 What is a Stock Split?
A stock split is a corporate action where a company increases the number of its outstanding shares by issuing more shares to current shareholders. This is typically done to make shares more affordable without changing the overall value of the investment. For example, in a 5-for-4 stock split, you’d receive 5 shares for every 4 you currently own, and the stock price would adjust accordingly.
Stock splits don’t change the market capitalization or the value of your holdings — they simply adjust the share count and price proportionally.
🧮 How Do You Calculate a Stock Split?
To calculate a stock split, you use this formula:
New Share Count = Old Share Count × (New Ratio ÷ Old Ratio)
New Stock Price = Old Stock Price × (Old Ratio ÷ New Ratio)
Example:
If you own 100 shares at $100 each and the company announces a 5:4 split:
Your new share count = 100 × (5 ÷ 4) = 125 shares
New stock price = $100 × (4 ÷ 5) = $80
Our calculator does the math instantly so you don’t have to worry about formulas.
