Stock Market Calculation Formula Explained
The calculator uses simple financial formulas to determine results. Let’s break them down:
1. Shares Purchased
To calculate how many shares you can buy:
Formula:
Shares = Investment Amount ÷ Buy Price
👉 This tells you how many whole shares your investment can purchase.
2. Final Value
The final value is calculated based on the selling price:
Formula:
Final Value = Shares × Sell Price
👉 This represents the total value of your investment after selling.
3. Profit or Loss
This shows whether your investment gained or lost value:
Formula:
Profit/Loss = Final Value − Investment Amount
👉 Positive value = profit
👉 Negative value = loss
4. Return Percentage
Return percentage shows performance in percentage terms:
Formula:
Return % = (Profit/Loss ÷ Investment Amount) × 100
👉 Helps you compare investment efficiency across trades.
Example Calculation
Let’s understand with a real-world example:
Scenario:
- Investment Amount = $1,000
- Buy Price = $50 per share
- Sell Price = $60 per share
Step 1: Calculate Shares
Shares = 1000 ÷ 50 = 20 shares
Step 2: Final Value
Final Value = 20 × 60 = $1,200
Step 3: Profit
Profit = 1200 − 1000 = $200
Step 4: Return Percentage
Return % = (200 ÷ 1000) × 100 = 20%
Final Result:
- Shares Purchased: 20
- Final Value: $1,200
- Profit: $200
- Return: 20%

Why Return Percentage Matters
Return percentage is more important than raw profit because:
- It allows comparison between different investments
- It shows efficiency of capital usage

- $200 profit on $2000 investment = 10% return
Even though second profit is higher, first investment is more efficient.
