Stock Split Calculator: Understand Your Post-Split Holdings

Our Stock Split Calculator is a powerful yet easy-to-use tool designed to help investors determine how a stock split affects their share quantity and per-share price. Whether it's a 2-for-1 split or a more complex scenario, this calculator gives you instant clarity on your new holdings.

Why Use a Stock Split Calculator?

Stock splits can be confusing, especially when planning future investments. This tool helps simplify the process by:

  • Calculating post-split share count and adjusted share price instantly.
  • Allowing you to test different split ratios (e.g. 3-for-2, 5-for-1).
  • Improving understanding of how splits impact portfolio structure and value.

How the Stock Split Formula Works

Step-by-Step Logic

The core calculation involves two components:

  • New Share Count = Original Shares × Split Ratio
  • New Share Price = Original Price ÷ Split Ratio

Example

Suppose you own:

  • 100 shares of Company XYZ
  • Each share is priced at $90
  • The company announces a 3-for-1 stock split

After the split:

  • New share count = 100 × 3 = 300 shares
  • New share price = $90 ÷ 3 = $30 per share

Total investment value remains unchanged at $9,000, but the structure of your holdings is now adjusted to reflect the split.

Frequently Asked Questions

The Stock Split Calculator is a simple yet effective online tool designed to help investors quickly determine how a stock split affects their share quantity and price per share. It’s essential for understanding post-split investment value and planning ahead with clarity.

When a company performs a stock split—such as a 2-for-1 or 3-for-1 split—your total investment value remains unchanged, but your number of shares increases while the price per share decreases proportionally. The calculator helps visualize this instantly.

Simply enter the original number of shares, original share price, and the split ratio (e.g., 3 for 1). The calculator then computes your new share total and the adjusted share price—no manual math required.

Yes! Our stock split and reverse split calculator supports both regular and reverse stock splits. Just enter the correct split ratio (like 1 for 10), and it will handle the rest.

No. Stock splits don’t change the total value of your investment. You simply own more (or fewer) shares at a different per-share price. The calculator confirms this for you during each calculation.

This tool is ideal for retail investors, traders, financial advisors, and anyone seeking a clearer picture of post-split scenarios. It’s perfect for use during earnings season or before major stock events.
