How it's calculated
Your average is a weighted average — shares bought at each price pull the average towards that price in proportion to how many you bought:
- Total invested = Σ (quantity × buy price) over all purchases.
- Total quantity = Σ quantity.
- Average price = total invested ÷ total quantity.
Example: buy 10 shares at ₹100 (₹1,000) and 20 shares at ₹110 (₹2,200). Total invested ₹3,200 over 30 shares gives an average of ₹106.67 — closer to ₹110 because you bought more there. This average is your gross breakeven before brokerage and statutory charges.
FAQ
How do you calculate the average price of a stock?
Multiply quantity by price for each purchase, add them to get total invested, then divide by total shares. That weighted average reflects how many shares you bought at each level.
What does averaging down mean?
Buying more after the price falls, which lowers your weighted average cost and breakeven — at the cost of a larger position in a single stock.
Is the average price the same as breakeven?
It's your gross breakeven. To break even after brokerage, STT and GST the market price needs to be a little above your average.
