Every price after the cut
Roblox takes 30% of the list price on a marketplace sale, so you keep 70% — rounded down to a whole Robux, since there is no such thing as a fractional one.
| Listed at | Roblox takes | You keep | Worth (DevEx) | Buyer paid |
|---|---|---|---|---|
| 5 R$ | 2 R$ | 3 R$ | $0.01 | $0.06 |
| 10 R$ | 3 R$ | 7 R$ | $0.03 | $0.13 |
| 25 R$ | 8 R$ | 17 R$ | $0.06 | $0.31 |
| 50 R$ | 15 R$ | 35 R$ | $0.13 | $0.63 |
| 80 R$ | 24 R$ | 56 R$ | $0.21 | $1.00 |
| 100 R$ | 30 R$ | 70 R$ | $0.27 | $1.25 |
| 250 R$ | 75 R$ | 175 R$ | $0.67 | $3.13 |
| 500 R$ | 150 R$ | 350 R$ | $1.33 | $6.25 |
| 1,000 R$ | 300 R$ | 700 R$ | $2.66 | $12.50 |
| 1,600 R$ | 480 R$ | 1,120 R$ | $4.26 | $20.00 |
| 5,000 R$ | 1,500 R$ | 3,500 R$ | $13.30 | $62.50 |
| 10,000 R$ | 3,000 R$ | 7,000 R$ | $26.60 | $125.00 |
The last two columns are the same sale from both ends: what your share cashes out for at $0.0038 per Robux, and roughly what the buyer spent to own the Robux they paid you with.
To net a round number, divide — do not add 30%
The fee comes off the list price, not off your share, so adding 30% always lands short. 500 plus 30% is 650, which leaves you 455 — not 500. Dividing by 0.70 is the correct move, then rounding up.
| To keep | Target ÷ 0.70 | List at | Actually keeps |
|---|---|---|---|
| 50 R$ | 71.43 | 72 R$ | 50 R$ |
| 100 R$ | 142.86 | 143 R$ | 100 R$ |
| 250 R$ | 357.14 | 358 R$ | 250 R$ |
| 350 R$ | 500.00 | 500 R$ | 350 R$ |
| 500 R$ | 714.29 | 715 R$ | 500 R$ |
| 1,000 R$ | 1428.57 | 1,429 R$ | 1,000 R$ |
| 5,000 R$ | 7142.86 | 7,143 R$ | 5,000 R$ |
Rounding up means you sometimes keep a Robux or two more than the target, never fewer. The Robux before-tax calculator does this for any figure.
How it is worked out
cut = price − keep
list = ceil(target ÷ 0.70)
Where price is what you list the item at and target is the Robux you want to end up with. The floor is why a 25 Robux sale keeps 17 rather than 17.5, and the ceiling is why netting an exact round number is usually impossible — you land on it or just above.
Worked example: a 500 Robux item
One sale, followed all the way through:
Roblox takes 30% = 150 R$
You keep = floor(500 × 0.70) = 350 R$
Worth at DevEx = 350 × 0.0038 = $1.33
Going the other way: to keep 500 Robux you list at ceil(500 ÷ 0.70) = 715, which actually leaves 500. The buyer, meanwhile, spent about $6.25 on the 500 Robux they handed over — roughly 4.7 times what your share cashes out for.
Assumptions & limitations
- A flat 30% marketplace fee. Group payouts, Premium payouts and experience revenue follow different rules — change the percentage in the calculator for those.
- Your share is floored to a whole Robux. Roblox does not pay fractions.
- The DevEx column assumes the standard $0.0038 rate and that your balance is Earned Robux; purchased and traded Robux cannot be cashed out.
- No income tax or payment fees are deducted here.
- Retail cost per Robux is an average across bundles and platforms.
Frequently asked questions
How much do I get if I sell something for 100 Robux?＋
You keep 70 Robux and Roblox takes 30. The fee is 30% of the list price and your share is rounded down to a whole Robux, so odd prices lose the fraction. At the standard DevEx rate those 70 Robux are worth about $0.27.
What should I list an item at to keep 500 Robux?＋
List it at 715 Robux. You cannot add 30% to 500 and get there - the fee is charged on the list price, not on your share, so you divide instead: 500 / 0.70 = 714.29, rounded up to 715. That leaves 500 Robux after the cut. Adding 30% would have given 650 and left you 455, which is short.
Is the 30% Robux tax the same for every kind of sale?＋
The 30% marketplace fee applies to marketplace sales of items such as clothing and accessories. Game passes and developer products keep 70% too, but group payouts, Premium payouts and experience revenue follow their own rules, so treat 70% as the common case rather than a universal one. The calculator lets you change the percentage for anything that differs.
