Investing in the stock market can be exciting but also involves a level of uncertainty. To make smarter investment decisions, you need to forecast how your portfolio might perform based on expected price changes, commissions, and holding periods. Our Stock Simulator Calculator is designed to help you visualize potential outcomes from your stock investments, making planning and analysis easier and more precise.


What is the Stock Simulator Calculator?

The Stock Simulator Calculator is an intuitive tool that lets you input your initial investment details and expected market changes to simulate your investment portfolio’s performance over a chosen holding period. It computes key metrics like:

  • Number of shares you can buy
  • New share price after expected percentage change
  • Portfolio value based on the new price
  • Total profit or loss from your investment
  • Return on investment (ROI) percentage

This calculator is perfect for beginners learning about stock investments, traders testing different scenarios, or anyone wanting a clear financial outlook without complicated spreadsheets.


Why Use a Stock Simulator Calculator?

Investing without forecasting can be risky. This tool empowers you by:

  • Visualizing Potential Outcomes: Estimate gains or losses based on price movement predictions.
  • Planning Your Investment: Determine how many shares you can purchase within your budget after factoring commissions.
  • Assessing Fees Impact: Include commissions per trade to see the real net profit or loss.
  • Understanding ROI: Know the percentage return on your investment to compare against other investment opportunities.
  • Making Informed Decisions: Test various price change scenarios to strategize buy, hold, or sell actions.

How to Use the Stock Simulator Calculator

Follow these easy steps to simulate your stock investment:

Step 1: Enter Your Initial Investment

Input the total amount of money you plan to invest in dollars. This is the budget you’ll allocate to buying shares.

Step 2: Input the Current Share Price

Enter the current price per share of the stock you want to invest in.

Step 3: Enter the Expected Price Change (%)

Estimate the percentage increase or decrease you expect in the stock price during your holding period. For example, enter 10 for a 10% rise or -5 for a 5% decline.

Step 4: Specify the Holding Period (Days)

How long you plan to hold the investment before selling. This field is mainly informational to reflect your investment horizon.

Step 5: Add Commission per Trade

Enter any commission fees per trade (buying or selling). If there are none, leave this at zero.

Step 6: Click Calculate

The calculator will display:

  • Number of Shares: How many shares you can buy after deducting commissions.
  • New Share Price: The projected price based on your expected percentage change.
  • Portfolio Value: The value of your investment at the new share price.
  • Total Profit/Loss: Your net gain or loss after commissions.
  • Return on Investment (ROI): Percentage gain or loss relative to your actual invested amount.

Example Calculation

Suppose you want to invest $5,000 in a stock currently priced at $50 per share. You expect the stock price to increase by 8% over 30 days, and your brokerage charges a $10 commission per trade.

  • Initial Investment: $5,000
  • Share Price: $50
  • Expected Price Change: 8%
  • Holding Period: 30 days
  • Commission: $10

The calculator will estimate:

  • Shares Purchased: floor((5000 - 10) / 50) = 99 shares
  • Actual Investment: (99 × $50) + $10 = $4,960
  • New Price: $50 × 1.08 = $54
  • Portfolio Value: 99 × $54 = $5,346
  • Profit/Loss: $5,346 - $4,960 - $10 = $376
  • ROI: ($376 / $4,960) × 100 = 7.58%

This means your investment could grow by approximately 7.58% in 30 days, net of commissions.
