How to Use the Stock Average Calculator
Add up to 10 purchase entries — quantity and buy price for each lot. Optionally enter the current market price to see overall profit/loss. Useful for calculating average after averaging down.
Stock Average Calculator Formula
Average Cost = Σ(qty × price) / Σ(qty)Example Calculation
Bought 100 shares @ ₹200, then 50 shares @ ₹150:
(100×200 + 50×150) / (100+50) = (20000+7500)/150
Average cost = ₹183.33; Total invested = ₹27,500
Frequently Asked Questions
What is stock averaging down?
Averaging down means buying more shares when the price drops to lower your average cost per share. This reduces the price you need to break even but increases your exposure to that stock.
