You’re publishing an app that requires 500 MiB of disk space. After uploading it to PatchKit, the package size has been reduced to 350 MiB. The first version is delivered to 500 new users in Europe. That makes 500 * (0.35 * $0.04) = $7 in total. You’re doing a second release with a package size of 400 MiB and diff (delta) package size of 15 MiB. It reached all your current users and got delivered to 250 new in Latin America. That way, second release costs 500 * (0.015 * $0.04) + 250 * (0.4 * $0.09) = $9.3. This makes $7 + 9.3 = $16.3 in total for two releases in one month.

You’re publishing a game that requires 1,5 GiB of disk space. You’re signed up for PatchKit PAYG plan with LZMA2 compression enabled ($100). Compressing the game with LZMA2 algorithm reduces its package size to 800 MiB. The first version is delivered to 5,000 new players in the USA. That makes 5000 * (0.8 * $0.04) + $100 = $260 in total. You’re doing a second release on the same month which has 1 GiB of package size, 100 MiB of diff (delta) package size. All your current players decided to upgrade and you’ve got 1,500 new players from Asia. That way, second release costs 5000 * (0.1 * $0.04) + 1500 * (1 * $0.06) = $110. This makes $260 + $110 = $370 in total for two releases on the first month.
