Which mutual fund shares do I use for average cost of sale of some shares?

In 2019 I sold some of the shares in a mutual fund. Since some shares were purchased long ago, the sale was "non-covered", i.e., I have to determine the basis myself. Which means I need to calculate the average share cost, then multiply by the number of shares sold, of course.

 

But...when calculating the average cost, which do I do:

 

  1. total the cost of the shares sold, divide by the number of the shares sold; or instead
  2. total the cost of all the shares I own right now, divide by the number of all shares I own?

You use the cost of ALL shares owned, before you sold, divided by the total number of all shares, before you sold.

You use the cost of ALL shares owned, before you sold, divided by the total number of all shares, before you sold.

Just to be sure...you're saying I use option #1 of the two I list, right?

No,that's not what I'm saying.  It's option #2 except you use the number of shares you owned BEFORE you sold any and the cost of all the shares you owned Before you sold any.

OK, I think I got it right -- please verify:

 

  • total the cost of all shares owned before the sale, divide by the number of all shares owned beforethe sale

(which I think is what you originally said!)

Correct.  You got it this time!
