Roblox DevEx fees and the Robux exchange rate

Roblox pays its creators twice removed from the money. A player spends Robux, the creator is credited Earned Robux, and only the Developer Exchange turns Earned Robux into dollars — at $0.0038 each, with a balance of at least 30,000 required before you can ask for any of it. On the sale itself, Roblox's commissions table gives the creator 30%, which means 70% of every avatar-item sale never reaches you. This guide sets out both halves as Roblox publishes them, with figures computed by the same engine as the Roblox DevEx calculator. The rates are quoted from Roblox's Developer Exchange and Marketplace fees and commissions pages and verified on 4 September 2026.

What Roblox charges, and what it pays

The two commission figures are the same size on purpose. Roblox's table states that the creator receives 30% of a Marketplace purchase and 30% of an in-game purchase; the in-game column adds a second recipient, the owner of the experience the item was bought in, who takes 40% of the sale while Roblox keeps 30%. Your cost is 70% either way.

Robux, Earned Robux and dollars

Only the third of those is money, which is why the calculator asks for a dollar figure: multiply your Robux price by $0.0038 and you have the sale valued at the DevEx rate — what the whole sale would be worth to you if Roblox took nothing. It is not what the player paid, because players buy Robux from Roblox at a retail price the Developer Exchange has nothing to do with.

On a 100,000-Robux Marketplace sale, $380.00 at the DevEx rate, the fee on $380.00 is $266.00 and you keep $114.00, an effective rate of 70%.

That leaves 30,000 Earned Robux, which is exactly the minimum balance a cash-out request needs. A tenth of that sale leaves a tenth of the balance:

On a 10,000-Robux sale, the fee on $38.00 is $26.60 and you keep $11.40, an effective rate of 70%.

Three thousand Earned Robux is real money — $11.40 — but you cannot ask for it until nine more sales like it have landed.

Note that the exchange rate is a rate and not a block. Roblox quotes it as "$114 USD for 30,000 Earned Robux", and it is tempting to read that as a package; 45,000 Earned Robux is $171.00, not two packages of $114.00.

The two ways to be paid more than 30%

Marketplace sales use a progressive revenue share: the further above its asset type's price floor an item is priced, the larger the creator's share, rising to 70% at six times the floor. Roblox publishes the multiples but not the floors, which sit inside a seller's own dashboard, so this calculator uses the base 30% and nothing on this page assumes more. In-game purchases never get the uplift at all — Roblox states that the progressive share "only applies to purchases in the Marketplace".

The second is the exchange rate. Roblox pays $0.0054 rather than $0.0038 for Earned Robux from developer products, passes, subscriptions and private servers bought by US players who have verified they are at least 18, in games that meet its eligibility rules. That is $162.00 per 30,000 Robux instead of $114.00. It is a large difference and a narrow door, and the calculator does not apply it.

Pricing so you clear the minimum

Working backwards is the more useful direction here, because the number that matters is the 30,000-Robux threshold rather than any single sale.

To keep $114.00 you charge $379.99, and the fee is $265.99.

The calculator's "I want to net" mode does the same for any target.

What this guide leaves out

The verified schedule covers United States creators paid in US dollars, and confidence is medium: the standard 0.0038 rate and both commission percentages each appear on a single official Roblox page, with no second Roblox page restating them. Only the 18+ rate and the 30,000-Robux minimum are corroborated elsewhere. Publishing advances and free-Limited per-unit fees, the 30-day escrow hold on every sale, resale commissions, and DevEx eligibility rules such as the age and account requirements are all out of scope. Roblox can change either exchange rate whenever it likes: the 18+ rate is itself an addition, effective 8 June 2026.

When these rates last changed

The 18+ rate took effect on 8 June 2026; everything else is dated from the day it was checked, 4 September 2026, because Roblox publishes these as live documentation pages with no effective date. The Roblox DevEx fee changelog holds the entries, the schedule is re-verified every 60 days, and the methodology explains the check. If a figure here disagrees with what Roblox shows you, report it.
