As far as I can tell the largest file size across all of the variants produced is shown as the file size on Amazon's product page for the book. Someone who has published may be able to comment on whether the file size on the product page is the same size used to calculate delivery costs.

Thanks for the breakdown. Our other KDP titles have only a handful of images, so I can't quite make an apples-to-apples comparison. But here is an example:
ePub: 1.6 MB
KDP says: Your book file size after conversion is 0.93 MB.
Listed delivery charge: $0.14
Amazon product page reported size: 5203 KB
KDP December report: Avg. Delivery Costs: $0.14
That's evidence that the amount the KDP author gets charged is related to what it says for the filesize in KDP, not what it says on the product page.
Still, this thread has me seriously reconsidering how I want to approach making the ePub for uploading to KDP.
