The formula

With a 30% fee the seller keeps 70%. The result is rounded down to a whole Robux.

you receive = floor(price × 0.70)

To go the other way, divide by 0.70 and round up. Then check the answer: the price must give you at least what you asked for.

price = ceil(wanted ÷ 0.70)

Worked example

You sell a shirt for 25 Robux. 25 × 0.70 = 17.5, rounded down to 17. Roblox keeps 8.

You want exactly 100 Robux. 100 ÷ 0.70 = 142.86, rounded up to 143. Check: 143 × 0.70 = 100.1, rounded down to 100. A price of 142 would give only 99.

Common mistakes

Taking 30% off and rounding up. The seller's share is rounded down.
Pricing at wanted × 1.3. That gives too little. 100 × 1.3 = 130, and 130 × 0.70 = 91.
Forgetting that the fee can change. Use the fee box above and check Roblox's help pages for the current figure.
