Investing in the stock market can be exciting, but understanding how your money is growing (or shrinking) is even more important. That’s why we developed the Stock Market Percentage Calculator a free and easy tool to help you track your investment performance using a simple percentage formula.

This calculator is designed for all types of investors from beginners to experienced traders who want a clear picture of how their investments are doing.

What Is a Stock Market Percentage Calculator?

A Stock Market Percentage Calculator helps you figure out how much your stock investment has increased or decreased over time, shown as a percentage. This tool is based on a very simple formula, yet it provides deep insights into your portfolio's performance.

It works by comparing the price you bought a stock at with its current value, or by calculating your total return including dividends, fees, and other factors.

How to Calculate Stock Market Percentage?

The most common formula used in our calculator is:

Percentage Change = (Current Price - Purchase Price) ÷ Purchase Price × 100

This gives you the percentage gain or loss on your investment.

For example, if you bought a stock for $100 and it is now worth $120, the calculation would be:

(120 - 100) ÷ 100 × 100 = 20%

That means you've earned a 20% return on your investment.

Our calculator can also include dividends, fees, and taxes to give you a more realistic view of your net return.

How to Use the Stock Market Percentage Calculator?

Using the calculator is very easy:

For Basic Percentage Change:

  2. Enter the current stock price.
  3. Click "Calculate".

  2. Enter the current stock price.
  3. Enter the number of shares you own.
  4. The calculator will show your percentage gain or loss and your total profit or loss.

For Total Return:

  1. Enter the price you paid per share.
  2. Enter the selling price.
  3. Add any dividends earned.
  4. Include any fees or taxes paid.
  5. Enter the number of shares.
  6. Get a full summary of your return, including total investment, net change, and total gain or loss.

Example Calculation

Let’s say you invest $1,000 every month for 30 years, and your investments grow at an average rate of 8% per year.

Over 30 years, your total investment would be:

$1,000 × 12 months × 30 years = $360,000

With compound growth at 8% annually, the future value would be about $1,360,000.

That's a gain of $1,000,000 on your original investment about 278% growth over time.

This example shows how powerful the stock market can be when you invest consistently and let compound interest work in your favor.

What Percentage of My Money Should Be in the Stock Market?

This depends on your age, risk tolerance, and investment goals. A common rule is the "100 minus age" rule. For example, if you’re 30 years old, 70% of your investments could be in stocks. Our calculator helps you monitor the growth of that portion over time.

How Many Points Is 1 Percent in the Stock Market?

In stock market indexes like the Dow Jones, 1 percent doesn't always mean 1 point. For example, if the index is at 30,000 points, then:

1% = 30,000 × 0.01 = 300 points

So a 300-point move equals a 1% change in this case. The calculator helps you understand these moves in your own investments.
