Robux calculator
Work out what you really receive when you sell something on Roblox, what price to set, and what Earned Robux are worth in US dollars. The calculator uses the rates Roblox publishes: 70% for sales in your game, 30% on the Marketplace, and 10,000 Robux = $38 through the Developer Exchange.
What you receive from a sale
You receive 70 Robux. Roblox keeps 30.
What price to set
Set the price to 143 Robux in your game, or 334 Robux on the Marketplace.
Earned Robux in US dollars (DevEx)
30,000 Robux = $114.00. That reaches Roblox's minimum of 30,000 Earned Robux.
Only Robux you earned can be cashed out, and only by creators who are 13 or older. Robux you bought are not paid back at this rate. Ask a parent before you set up payouts.

Where the rates come from
From Roblox's Creator Hub page Earn on Roblox, read on 2026-11-12: “Creators generally earn 70% of anything they sell in Robux in their game, 30% of anything they sell in the Marketplace”, “10,000 Robux = $38 USD”, and cashing out needs “at least 30,000 Earned Robux” and an age of 13 or older. Roblox can change these rates, and some item types have their own rules, so check Roblox's page before you rely on a number. RoRadar does not estimate anything here: the calculator only multiplies your number by Roblox's rate.
