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(1,000 × 7 ÷ 10) = 700.
Working backwards? See 1,000 Robux with tax. To receive 1,000 you would list at 1,429.

Robux transfer version
1,000 Robux is more than the 500 Robux limit for one transfer, so it takes 2 transfers. Sent in the largest chunks possible, the recipient gets 900 in total (90%). Transferred Robux are not eligible for DevEx.
