For testing purposes, you can use
Kindleunpack to split the mobi file into azw3/KF8 and standard mobi files. However, AFAIK, KDP won't accept AZW3 file uploads.
BTW, if you generate a mobi file with Kindle Previewer you can click Compilation Details to display the kindlegen log. At the end, it'll indicate the size of the standard mobi and KF8 components.
For example:
Code:
Info(prcgen):I15000: Approximate Standard Mobi Deliverable file size: 0000534KB
Info(prcgen):I15001: Approximate KF8 Deliverable file size: 0000579KB
(The same information is also being displayed if you use Kindlegen directly.)

That is correct, Amazon will only charge delivery for the actual file size of the file that the buyer downloads.
