Why average price matters
When you buy at different prices, average cost gives a realistic reference for portfolio decisions, stop-loss planning, and target setting.
Average cost formula
Average Price = Total Invested Amount / Total Quantity
Add all lots, then divide cumulative value by cumulative quantity.

Average price example
Scenario: Bought 100 shares at Rs 240 and 150 shares at Rs 210.
Inputs
- Lot 1 = Rs 24,000
- Lot 2 = Rs 31,500
Calculation
- Total invested = Rs 55,500
- Total quantity = 250
- Average price = 55,500/250 = Rs 222
Result: New average buy cost is Rs 222 per share.
