How it works
Weighted Average Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.

Bought 10 at $4 and 30 at $5? Put 4 and 5 as values and 10 and 30 as weights: the average price is $4.75, not the $4.50 a plain average gives.
