Robux Tax Calculator (30% Fee)

Roblox does not charge a government-style tax, but it keeps a cut of every Robux sale, and players call that cut the Robux tax. For passes and developer products sold in an experience the cut is 30%, so you keep 70%. This calculator works in both directions: what you keep from a price, or the price to set so a donation pass, a friend's purchase or a trade ends with an exact amount in your account.

How to use this tool

1. Choose the direction: from a price to what you keep, or from what you want to keep to the price.
2. Enter the Robux amount.
3. Pick what is being sold, because the share differs for passes, avatar items and Limited resales.
4. Read the result and the quick-reference table.

Formula

Keep = floor(price × share) · Price = smallest whole number with floor(price × share) ≥ target

The share is 70% for passes and developer products, 30% for avatar items sold in the Marketplace at the price floor, and 50% for the reseller of a community-created Limited. With a 70% share the price is about target ÷ 0.7, rounded up.

Example

To receive exactly 1,000 Robux from a pass, divide by 0.7: 1,000 ÷ 0.7 = 1,428.57, so set the price to 1,429 Robux. Roblox keeps 429, and floor(1,429 × 0.7) = floor(1,000.3) = 1,000 lands in your account. The other way round, a 1,000 Robux price keeps 700.
