Stock Average Cost Calculator
Find out your average cost per share when you’ve bought the same stock at different prices.
Why Calculate Average Cost?
When you buy the same stock multiple times at different prices, your average cost tells you:
- Your true break-even point
- How current price compares to your average
- Whether you’re up or down overall
How to Use This Calculator
Add each purchase you made:
- Number of Shares: Shares bought in this purchase
- Price Per Share: What you paid per share
- Fees (optional): Trading fees for this purchase
Add as many purchases as you need! The calculator shows:
- Average cost per share
- Total shares owned
- Total invested
Common Scenarios
Buying the Dip: If a stock drops, buying more lowers your average cost
- Bought 10 shares at $50 = $500
- Stock drops to $40, buy 10 more = $400
- Average cost = $45 per share (not $50!)
Dollar Cost Averaging: Regular purchases naturally average your cost over time
Warning: Don’t “average down” on failing companies - make sure the fundamentals are still strong!
