How It Works
How It Works
This calculator measures how much your stock investment has increased or decreased in percentage terms. It compares the price you originally paid for the stock to its current market price.
The formula subtracts the purchase price from the current price to find the change in value. Then it divides that change by the original purchase price and multiplies by 100 to convert the result into a percentage.
- Step 1: Subtract purchase price from current price
- Step 2: Divide the difference by the purchase price
- Step 3: Multiply the result by 100 to get a percentage
- Uses the formula: ((current_price - purchase_price) / purchase_price) × 100
Understanding the Results
The result shows your investment performance as a percentage. A positive number means your stock has gained value, while a negative number means it has lost value.
This percentage helps you quickly compare performance across different stocks, regardless of their actual prices.
- Positive percentage = Profit
- Negative percentage = Loss
- 0% means no gain or loss
- Higher percentages mean stronger returns
Frequently Asked Questions
How do I calculate my stock profit or loss percentage?
Enter the price you originally paid per share in the "Purchase Price per Share" field and the current market price in the "Current Price per Share" field. The calculator applies the formula ((current_price - purchase_price) / purchase_price) * 100. The result shows your percentage gain if positive or percentage loss if negative.
What does a negative percentage result mean?
A negative result means the current price is lower than your purchase price. This indicates a loss on your investment. For example, if you bought a stock at $100 and it is now $80, the calculator will show -20%.
What does a positive percentage result mean?
A positive percentage means the current price is higher than your purchase price. This reflects a gain on your investment. For instance, if you bought at $50 and the stock is now $65, the result will show a 30% profit.
Should I include the number of shares I own?
No, this calculator measures percentage change per share, not total dollar profit or loss. The percentage return is the same regardless of how many shares you own. To calculate total profit in dollars, you would multiply the per-share gain by the number of shares.
Does this calculator include dividends or fees?
No, this calculator only measures price change between purchase and current value. It does not account for dividends, brokerage fees, or taxes. For a more complete return calculation, you would need to factor those elements in separately.
When should I use this calculator?
Use this calculator whenever you want a quick way to measure how much a stock has gained or lost in percentage terms. It’s helpful for comparing performance across different investments. Percentage returns make it easier to evaluate growth regardless of stock price levels.
