Frequently Asked Questions

Stock averaging is the practice of buying more shares of a stock you already hold at a different price to change your average cost per share. Buying at lower prices reduces your average (averaging down).
Averaging down means buying more shares when the stock price falls below your original purchase price, which reduces your average cost and lowers the breakeven point.
Averaging down can be profitable if the stock eventually recovers, but it increases risk if the stock continues to fall. It should only be done on fundamentally strong stocks.
Average Cost = Total Amount Invested ÷ Total Number of Shares. E.g., buy 100 shares at ₹150 and 50 shares at ₹120: Total = ₹15,000 + ₹6,000 = ₹21,000; Average = ₹21,000 ÷ 150 = ₹140.
Breakeven price is the price at which you neither make a profit nor a loss. It equals your average buy price plus any brokerage and transaction charges.
Our calculator supports two buy transactions. For more lots, you can calculate average of first two, then use that average as the price for a third transaction.
