Why are the two numbers so different?
Buying Robux and cashing out Robux use completely different rates. Players buy at roughly $1 per 80–100 R$ depending on the pack, but creators cash out through the Developer Exchange at $350 per 100,000 R$ — about a third of a cent each. The gap is Roblox's margin, and it's also why "free Robux" sites promising huge payouts are lying: the math never works.
