Stock Split Price Adjustment Calculator
Calculate the new stock price after a stock split.
Instructions:
- Enter the **pre-split stock price** (the price before the stock split).
- Enter the **stock split ratio** (for example, for a 2-for-1 split, enter 2).
- Click “Calculate Adjusted Price” to see the **adjusted stock price** after the split.
Formula:
The adjusted stock price is calculated using the following formula:
Where:
- Pre-Split Stock Price is the price of the stock before the split.
- Stock Split Ratio is the ratio of the split (e.g., 2 for a 2-for-1 split, 3 for a 3-for-1 split).
A stock split is a corporate action in which a company divides its existing shares into multiple new shares, increasing the number of shares outstanding. While this increases the total shares in circulation, the total value of an investor’s holding remains the same—just distributed across a larger number of shares.
The purpose of a stock split is often to lower the trading price of the company’s stock to make it more affordable for retail investors, without changing the company’s overall market capitalization.
The Stock Split Price Adjustment Calculator helps you determine how the price of a stock will change after a stock split, and how many shares you will own following the split.
Understanding Stock Splits
When a company splits its stock, it typically announces a split ratio, such as 2-for-1, 3-for-1, or 5-for-2.
- A 2-for-1 stock split means that for every one share an investor owns, they will receive two shares after the split, and the price per share will be halved.
- A 3-for-2 stock split means that for every two shares owned, the investor will receive three shares, and the price per share will be reduced by one-third.
Stock Split Adjustment Formula
To calculate the price and number of shares after a stock split, use the following formulas:
- New Share Price:
New Price per Share = Original Price per Share ÷ Split Ratio - New Number of Shares:
New Shares = Original Number of Shares × Split Ratio
For example, if a company announces a 2-for-1 stock split, the price of each share will be halved, and the number of shares will double.
Stock Split Example
Assumptions:
- Original Stock Price: $100 per share
- Number of Shares Owned: 50 shares
- Stock Split Ratio: 2-for-1 (for every 1 share, you get 2 new shares)
Step 1: Calculate the New Stock Price
New Price per Share = $100 ÷ 2
New Price per Share = $50
After the stock split, the price per share will be $50.
Step 2: Calculate the New Number of Shares
New Shares = 50 × 2
New Shares = 100
After the stock split, the number of shares you own will be 100 shares.
Result:
- Before Split: 50 shares at $100 each = $5,000 total value
- After Split: 100 shares at $50 each = $5,000 total value
While the price of each share is lower, the total value of the investment remains unchanged at $5,000.

| 4-for-3 | $120 | 60 | $90 | 80 | $7,200 |
| 5-for-4 | $150 | 40 | $120 | 50 | $6,000 |

Key Considerations in Stock Splits
- No Change in Total Value:
The total value of your investment remains the same after a stock split. You may own more shares, but each share is worth less. The overall market capitalization of the company is unchanged. - Stock Splits Don’t Affect Company Fundamentals:
A stock split does not change the company’s earnings, revenue, or overall financial health. It is merely a cosmetic change to the stock price and the number of shares outstanding. - Stock Split vs. Stock Dividend:
A stock split increases the number of shares, while a stock dividend gives you additional shares based on a fixed percentage of your holdings, not a ratio. A stock dividend can increase your holdings and the company’s equity without affecting the stock price directly. - Reverse Stock Splits:
In a reverse stock split, the company consolidates shares, meaning shareholders receive fewer shares with a higher price per share. For example, a 1-for-2 reverse stock split means that for every two shares you own, you will now own one share, but at twice the original price. - Market Perception:
While a stock split doesn’t change a company’s fundamentals, it can affect market perception. A stock split can make a high-priced stock more accessible to individual investors, which might increase demand for the stock. Similarly, a reverse stock split might indicate that the company is trying to raise its stock price for listing requirements or other strategic reasons.
Stock Split Price Adjustment FAQ
Q: Why do companies split their stock?
A: Companies usually split their stock to make shares more affordable for small investors, increase liquidity, or make the stock appear more attractive by lowering the share price.
Q: Do stock splits affect the value of my investment?
A: No. A stock split only changes the number of shares you own and the price per share. Your total investment value remains the same.
Q: How does a reverse stock split work?
A: A reverse stock split consolidates shares, so you will receive fewer shares, but each share will be worth more. For example, in a 1-for-2 reverse split, for every two shares you own, you would receive one new share at double the price.
Q: Will a stock split impact my taxes?
A: Generally, a stock split doesn’t trigger any taxable event. However, if you sell your shares, any gains or losses would be subject to taxation. It’s always best to consult a tax professional for specific advice related to stock transactions.
Q: How do stock splits affect dividends?
A: If the company pays dividends, the amount of the dividend may be adjusted post-split. For example, if a stock undergoes a 2-for-1 split, the dividend per share will likely be halved, but the total dividend payout remains the same, assuming the company maintains the total payout amount.
Conclusion
The Stock Split Price Adjustment Calculator helps you understand how a stock split affects your holdings, the share price, and your total investment value. While stock splits do not alter the total value of your investment, they can impact your portfolio’s composition by increasing the number of shares you own while reducing the price per share.
By using this calculator, you can easily determine the impact of any stock split, make informed decisions about your investments, and monitor how these changes influence your portfolio over time.
