DCA / average entry price calculator

Combine several buys into one average entry price. Free, private, runs in your browser.

How it works

For each buy, units = Amount ÷ Price. Average entry price = Total spent ÷ Total units.

Example: $100 at 10 (10 units) plus $100 at 5 (20 units) gives $200 ÷ 30 = 6.67, not the simple average of 7.5.

FAQ

Why is my average lower than the simple average of prices?

Spending the same amount at a lower price buys more units, so lower prices weigh more in the average.

Should I include fees?

For precision, add fees to the amount spent on each buy.

Can I use it for selling?

This tool averages buys. For partial sells, your average entry price stays the same. Only the remaining units change.
