Frequently Asked Questions — Stock Average Price Calculator
What is a Stock Average Price Calculator?
It helps you find the average cost per share when you have bought the same stock multiple times at different prices. This is essential for calculating your actual cost basis and profit or loss.
What is the formula for stock average price?
Average Price = Total Amount Invested ÷ Total Shares Purchased. Example: Buy 100 shares at ₹200 and 200 shares at ₹150 → Average = (100×200 + 200×150) ÷ 300 = ₹166.67
Why is averaging down risky?
Averaging down means buying more shares when price falls. While it reduces average cost, it also increases total exposure. If the stock continues to fall, losses multiply. Always check company fundamentals before averaging down.
Can I use this for mutual fund units?
Yes. The same formula works for mutual fund NAV averaging. Enter the NAV as the price and units purchased as the quantity for each SIP installment.
