Stock Split Calculator
Calculate new share count and price after stock splits or reverse splits
About this calculator
A stock split calculator helps investors determine how stock splits or reverse splits affect their shareholdings. When companies split their stock, the number of shares increases while the price per share decreases proportionally, maintaining the same total investment value. This calculator instantly computes your new share count and adjusted share price after any split ratio, helping you understand the impact on your portfolio without changing your ownership percentage or total investment value.
How to use
Enter your current number of shares and the current share price. Input the split ratio (e.g., 2:1 for a two-for-one split, or 1:5 for a reverse split). The calculator will automatically display your new share count and the adjusted price per share after the split takes effect.
Frequently asked questions
Does a stock split change my investment value?
No, stock splits don't change your total investment value. You'll have more shares at a lower price or fewer shares at a higher price.
What's the difference between a split and reverse split?
A stock split increases share count and decreases price, while a reverse split decreases share count and increases price per share.
How do I enter a 3-for-2 stock split ratio?
For a 3-for-2 split, enter 3:2 or 1.5 as the split ratio, meaning you receive 3 shares for every 2 you own.
