How the Roblox tax works
The “Roblox tax” is a 30% marketplace fee. Here's exactly where it applies and how the split is calculated.
What the tax actually is
When Robux changes hands on the Roblox marketplace (a shirt, a UGC accessory, a Game Pass, a developer product), Roblox keeps a share of the sale as a platform fee. That fee is commonly called the “Roblox tax.” The standard rate is 30%, which means the creator keeps 70% of the listed price as Robux.
The 70/30 split, and how it's rounded
Creators are paid in whole Robux, and the creator's 70% share is rounded down. Any fractional Robux left over is absorbed into the fee. So for a sale of P Robux:
- Earnings =
floor(P × 0.70) - Fee =
P − earnings
A 1,000 Robux sale returns 700 Robux with a 300 Robux fee: a clean 70/30 split. A 99 Robux sale returns 69 Robux (99 × 0.70 = 69.3, rounded down), so the fee is 30 Robux, or a touch over 30% on that small sale. The rounding only ever nudges the effective fee slightly upward, never below 30%.
Where it applies
- Clothing and UGC items sold on the marketplace.
- Game Passes and developer products sold in your experiences.
- Most creator-to-player Robux transactions on the platform.
The fee is separate from what happens when you later cash out. Converting Robux to real money runs through the Developer Exchange, which uses its own rate. See how DevEx works.
Planning prices around the fee
Because the fee is a fixed percentage, you can price for a target payout. To end up with a specific number of Robux, divide your target by 0.70 and round up to the nearest whole Robux, or let the Before Tax mode do it. Pricing a Game Pass works the same way; there's a dedicated walkthrough in how to price a Game Pass.
