How do I know what share of my orders come from extension sessions?

You can't read it from Shopify or GA4, because an extension runs in the shopper's browser and isn't a traffic source. Measuring it needs a script on your storefront that sees extensions act, which is what the how-to guide covers.

Is all of this money lost?

Not all of it. Some shoppers would have used a code anyway, and some would have left without one. The calculator gives the size of the exposure; a holdout test gives the share that's real for your store.

What if the extension doesn't earn commission from me?

Set commission to zero. An extension earns commission only through your affiliate program, directly or through a network, but the codes it applies cost you either way.

Discounts a month$1,200

Commission a month$204

How it's worked out

Orders with an extension-applied code are your monthly orders, times the share from sessions with an extension, times the share of those that carry a code the extension added.
The discount cost is those orders' value times the average discount. The commission is charged on what the shopper paid after the discount, when the extension earns one.
It's what your inputs imply, not a measurement. Some of those shoppers would have found a code anyway, and some orders wouldn't have happened without one. A holdout test tells you which.
