THE MATH

Stock Average Price Formula

The weighted average reflects all shares and purchase costs entered.

Weighted average acquisition cost

Average price = (Total purchase cost + fees) ÷ Total shares

Total purchase cost = Σ (Shares bought × Purchase price per share)

Current market value = Current price × Total shares

Estimated unrealized P/L = Current market value − Total purchase cost including fees

Unrealized P/L (%) = Unrealized P/L ÷ Total cost × 100

WORKED EXAMPLE

Stock Average Price Example

Illustrative calculation before transaction fees.

Purchase	Shares	Price	Cost
Purchase 1	10	$100	$1,000
Purchase 2	10	$80	$800
Total	20	—	$1,800

Average price = $1,800 ÷ 20 = $90 per share. If the current price is $95, market value is $1,900 and estimated unrealized profit is $100 before fees and taxes.
