## Formula for Calculating Profit or Loss Percentage

The formula to calculate the percentage gain or loss on an investment is as follows:

Percentage Gain or Loss = (Current Value – Original Value) / Original Value x 100%

Where:

• Current Value is the current value of the investment
• Original Value is the initial value of the investment

### Calculating Percentage Gain

To calculate the percentage gain on an investment, follow these steps:

1. Determine the original value of the investment. Let’s say you purchased a stock for \$1,000.
2. Determine the current value of the investment. Let’s say the current value of the stock is \$1,500.
3. Use the formula to calculate the percentage gain. The calculation would be as follows:

Percentage Gain = (\$1,500 – \$1,000) / \$1,000 x 100% Percentage Gain = 50%

In this example, the percentage gain on the investment is 50%.

### Calculating Percentage Loss

To calculate the percentage loss on an investment, follow these steps:

1. Determine the original value of the investment. Let’s say you purchased a stock for \$1,000.
2. Determine the current value of the investment. Let’s say the current value of the stock is \$500.
3. Use the formula to calculate the percentage loss. The calculation would be as follows:

Percentage Loss = (\$500 – \$1,000) / \$1,000 x 100% Percentage Loss = -50%

In this example, the percentage loss on the investment is 50%. Note that the result is negative because the investment has decreased in value.

### Calculating Percentage Gain or Loss on a Portfolio

Suppose you have a portfolio of stocks, and the value of the portfolio has increased from \$100,000 to \$120,000. Let’s use the formula to calculate the percentage gain:

Percentage Gain = [(Current Value – Original Value) / Original Value] x 100% Current Value = \$120,000 Original Value = \$100,000 Percentage Gain = [(\$120,000 – \$100,000) / \$100,000] x 100% Percentage Gain = 20%

In this example, the percentage gain on the portfolio is 20%.

## Conclusion

Calculating the percentage gain or loss on an investment is essential to evaluate the performance of your investments. By following the steps and formula outlined in this article, you can make informed investment decisions and assess your portfolio’s performance accurately.

Remember that past performance is not an indicator of future results, and it’s essential to conduct thorough research before making any investment decisions.
