What is Stock Average Price?
When you buy shares of the same stock at different prices over time (dollar-cost averaging or averaging down), your effective cost per share is the weighted average of all purchase prices. Knowing this helps you decide at what price selling turns profitable.
Formula
Weighted average across all lots:
Average Price = Σ(price × qty) / Σ(qty) = total money invested / total shares bought Example: Buy 10 @ ₹100 → ₹1,000 Buy 20 @ ₹ 80 → ₹1,600 Total: 30 shares, ₹2,600 invested Average = ₹2,600 / 30 = ₹86.67
How to use this calculator
Add your purchase lots — enter the buy price per share and the quantity for each transaction. The calculator computes the weighted average buy price across all lots. You can add or remove lots as needed.
