Average Buy Price Calculator
Work out your weighted average cost across every purchase you've made.
What is a weighted average buy price?
If you bought the same coin at different prices over time, your weighted average price is the total amount spent divided by the total coins bought - not a simple average of the prices. This gives a more accurate picture of your true break-even price than averaging the prices alone.
Frequently Asked Questions
Why not just average the prices I paid?
A simple average treats every purchase equally regardless of size. A weighted average accounts for how much you bought at each price, which is a more accurate break-even point if your purchase sizes varied.

Yes, click "+ Add Purchase" to add as many buy entries as you need.
Does this account for fees?
