Investing in stocks involves making smart, informed decisions. Whether you’re buying your first share or managing a diversified portfolio, understanding the price per share, total cost, and potential profit or loss is essential. But with so many variables — share quantity, purchase price, broker fees, etc. — it’s easy to get confused.
What Is a Share Price?
A share price is the current market value of one unit (or "share") of a company’s stock. The price fluctuates based on market conditions, company performance, and investor sentiment. When you invest in stocks, the share price determines how many units you can purchase and ultimately impacts your gains or losses.

- Number of shares purchased
- Price per share
- Optional: Brokerage fees
Result: Total investment cost (including fees)
2. Calculate Price per Share
Input:
- Total investment amount
- Number of shares

Share Price Calculator Formulas (Plain Text)
Here are the basic formulas the calculator uses:
1. Total Investment Cost
Formula:Total Cost = (Number of Shares × Price per Share) + Fees
2. Cost per Share
Formula:Cost per Share = Total Investment / Number of Shares
3. Profit or Loss
Formula:Profit/Loss = (Selling Price - Purchase Price) × Number of Shares - Fees - Taxes
4. Return on Investment (ROI)
Formula:ROI (%) = [(Final Value - Initial Investment) / Initial Investment] × 100
Example Calculations
Example 1: Total Investment
You want to buy 100 shares of a stock priced at $50 each with a $10 brokerage fee.
Total Cost = (100 × $50) + $10 = $5,010
Example 2: Price Per Share
You invested $2,500 to buy 50 shares.
Cost per Share = $2,500 ÷ 50 = $50
Example 3: Profit or Loss
You bought 200 shares at $25, and sold them at $35, with $20 fees.
Profit = (35 - 25) × 200 - 20 = $1,980
