The math
Roblox keeps a 30% Marketplace Fee on game passes and developer products and you receive 70%, rounded down to a whole Robux: floor(10,000 × 7 ÷ 10) = 7,000.

Robux transfer version
10,000 Robux is more than the 500 Robux limit for one transfer, so it takes 20 transfers. Sent in the largest chunks possible, the recipient gets 9,000 in total (90%). Transferred Robux are not eligible for DevEx.
