📉 Average Stock Price Calculator – Track Your Portfolio Entry Price Accurately

✅ Introduction

When you buy the same stock multiple times at different prices, your Average Stock Price reflects the total cost basis per share. It helps you understand your true entry point and decide when to sell, hold, or average down.

This is especially helpful in:

• Swing trading & long-term investing
• SIP (Systematic Investment Plan) tracking
• Portfolio rebalancing

📌 What Is Average Stock Price?

Average Stock Price is the total money spent on a stock divided by the total number of shares purchased.

🧮 Formula (Plain Text)

Average Stock Price =
(Total Shares₁ × Price₁ + Total Shares₂ × Price₂ + …) ÷ (Total Shares₁ + Shares₂ + …)

Or simply:

Average Price = Total Cost ÷ Total Shares

🧪 Example

You purchased:

• 100 shares at ₹80
• 50 shares at ₹60

Step-by-step:

• Total Cost = (100 × ₹80) + (50 × ₹60) = ₹8000 + ₹3000 = ₹11,000
• Total Shares = 100 + 50 = 150

Average Stock Price = ₹11,000 ÷ 150 = ₹73.33

✅ So, your average buy price is ₹73.33/share

❓ Frequently Asked Questions (FAQs)

1. What if I sell some shares?

The average changes only when you buy more. Selling doesn’t affect the average stock price — but it affects your gains/losses.

2. Can I use this for SIP in mutual funds?

Yes, the same concept applies. Just plug in units and NAV values.

3. Does this include brokerage or taxes?

Only if you include them manually in the total cost. Otherwise, it reflects the raw trade prices.

4. Is average price the same as current market price?

No. Average price is your cost basis. Current market price is what the stock is trading at now.
