What is Stock Averaging?

Stock averaging refers to the practice of buying shares of the same company at different price points. Investors often average down when prices fall or average up when prices rise. Knowing your average price helps determine your break-even level and profit or loss accurately.

How Stock Average is Calculated

The formula used is:

Average Price = Total Investment ÷ Total Shares

Total Investment = Sum of (Quantity × Buy Price)

Example

If you bought:

  • 10 shares at $100
  • 20 shares at $80

Total Investment = (10×100) + (20×80) = 2600

Total Shares = 30

Average Price = 2600 ÷ 30 = 86.67
