What Is the Robux Tax?
If you sell anything on Roblox, a game pass, a developer product, a UGC item, or even take donations in a game like Pls Donate, Roblox keeps a cut. That cut is the marketplace tax, and it's a flat 30%. So you walk away with 70% of whatever the item sold for.
Here's a quick example. You price a game pass at 1,000 Robux. Someone buys it. You don't get 1,000. Roblox takes 300, and 700 lands in your account. That gap catches a lot of new creators off guard, which is exactly why this calculator exists. Type in a number and it shows you the real take, instantly.
How the Calculator Works
The tool has three modes, and each one answers a different question creators actually ask.
- After-Tax. You enter a sale price and it shows what you keep once the 30% is gone. Good for checking a pass or product before you publish it.
- Price to Set. You know how much Robux you want to end up with, and it tells you the price to list. This one handles Roblox's rounding for you, so you don't come up short by a Robux or two.
- DevEx Cash-Out. You enter earned Robux and it estimates the real USD you'd get through the Developer Exchange program.
Robux to Real Money: How DevEx Works
The 30% tax is only half the story for serious creators. The other half is turning that Robux into actual cash. Roblox lets eligible developers do this through a program called DevEx, short for Developer Exchange.
The rate isn't the same as what players pay to buy Robux. It's lower, because buying and cashing out are two different things. As of 2026 the standard DevEx rate is about $0.0038 per Robux. There's also a higher US 18+ rate of $0.0054, and an older $0.0035 rate that still applies to some older balances. You can switch between these in the calculator.
A Full Example
Say your game earns 1,000,000 Robux in a month. First the tax. Roblox takes 30%, leaving you 700,000 Robux. Now DevEx. At $0.0038 per Robux, that 700,000 becomes roughly $2,660 in real money. The calculator does both steps in one go so you don't have to.
Robux Value at a Glance
Here's a simple reference for common amounts, after the 30% tax and at the standard DevEx rate.
| Sale Price | After Tax | DevEx (USD) |

| 1,000 | 700 | $2.66 |
| 10,000 | 7,000 | $26.60 |
| 30,000 | 21,000 | $79.80 |

| 1,000,000 | 700,000 | $2,660.00 |
Rates can change, so always check the official Roblox DevEx page before a real cash-out. This tool is here for quick planning, not financial advice.
