What is a stock split?
A stock split is a corporate action where a company divides its existing shares into multiple shares to boost liquidity. For example, in a 2-for-1 stock split, each share is divided into two, halving the price but doubling the number of shares. The total value of your investment stays the same.Examples: 2-for-1, 3-for-2, reverse splits

Stock Split Calculator FAQs
Carefully crafted with the latest technologies and designed with user experience in mind.
Q: What does a 2-for-1 stock split mean?
A 2-for-1 stock split means each share you own becomes two, while the stock price is cut in half. For example, 100 shares at $50 become 200 shares at $25. Our stock split calculator shows exactly how this works for any ratio.
Q: How do I calculate a stock split manually?
To calculate a stock split manually, multiply your current number of shares by the split ratio (e.g., 2 ÷ 1 = 2x). Then divide the current price per share by the same factor. Or skip the math with our stock split calculator.
Q: Does a stock split affect my total investment value?
No — your total investment value stays the same. While your number of shares increases, the price per share decreases proportionally. A stock split calculator can confirm your post-split values in seconds.
Q: Is a reverse stock split good or bad?
A reverse stock split reduces your share count but raises the share price. It doesn’t change your total value, but it can be a sign a company is trying to avoid delisting. Use a reverse stock split calculator to see the impact.
