If you bought the same asset at different prices, your break-even price is the weighted average of those buys. Enter up to three purchases and the current price to see your average cost, total cost and unrealized profit or loss.
The formula
Average price = Total cost ÷ Total quantity
Each purchase is weighted by its size, so larger buys move the average more.
Worked example
| Buy | Price | Quantity | Cost |
|---|---|---|---|
| 1 | $100 | 10 | $1,000 |
| 2 | $90 | 20 | $1,800 |
| 3 | $80 | 30 | $2,400 |
Total: 60 units for $5,200, so the average price is $86.67. At a current price of $95, profit is (95 − 86.67) × 60 = $500.
A caution about averaging down
Buying more as the price falls lowers your average, but it also increases your exposure to a losing trade. Decide the maximum total position before the first buy, and keep total risk within your plan. Use the position size calculator for the full size.
FAQ
Is this the same as dollar-cost averaging? Dollar-cost averaging means buying fixed amounts at regular intervals. The average price calculation applies to any set of purchases.
Are fees included? No. Add fees to the cost if you want a true break-even.
