About this tool
This Robux tax calculator shows how many Robux you get when you sell something on Roblox. Roblox keeps a fee from each sale, which players call the Robux tax or the Roblox tax. Type in a price and the calculator shows what you receive. Switch to the reverse mode and it tells you what price to list so you end up with the exact amount you want. It works as a Roblox tax calculator for game passes, items and other sales. Your numbers stay on your device.
How to use it
- Pick a mode. Choose the first to start from a price. Choose the second to start from the amount you want to receive.
- Type the number of Robux.
- Read the answer. In the reverse mode it shows the list price and checks that you really get your target after the fee.
The math
With the standard 30% fee, you keep 70% of the price. To find what you get, multiply the price by 0.7. To find the price you need, divide the amount you want by 0.7 and round up to a whole number. For example, to receive 700 Robux you list at 1,000. Robux come in whole numbers, so this tool rounds your payout down. The real payout can differ by a Robux in rare cases.
| List price | Roblox keeps (30%) | You receive |
|---|---|---|
| 10 Robux | 3 Robux | 7 Robux |
| 50 Robux | 15 Robux | 35 Robux |
| 100 Robux | 30 Robux | 70 Robux |
| 250 Robux | 75 Robux | 175 Robux |
| 500 Robux | 150 Robux | 350 Robux |
| 1,000 Robux | 300 Robux | 700 Robux |
| 5,000 Robux | 1,500 Robux | 3,500 Robux |
Price needed for the amount you want
| I want to receive | List price needed |
|---|---|
| 50 Robux | 72 Robux |
| 100 Robux | 143 Robux |
| 350 Robux | 500 Robux |
| 700 Robux | 1,000 Robux |
| 1,000 Robux | 1,429 Robux |
| 5,000 Robux | 7,143 Robux |
If you list a little higher than the exact math, you are safe from rounding. If you list lower, you could end up short.
Robux to dollars: Developer Exchange (DevEx)
Creators who earn Robux from their experiences can cash out through Developer Exchange. These details come from Roblox's own pages, checked on October 11, 2026:
| Rate | Per Robux | 30,000 Robux is worth | Applies to |
|---|---|---|---|
| Standard | $0.0038 | $114.00 | Earned Robux from Sept 5, 2025 onward |
| Older balance | $0.0035 | $105.00 | Earned Robux before Sept 5, 2025 |
| US 18+ spend rate | $0.0054 | $162.00 | Eligible spend by verified US players aged 18 and over |
- You need at least 30,000 Earned Robux to cash out.
- Creators must be at least 13 years old, and the program asks for a verified email and tax forms. Ask a parent or guardian before you try to cash out.
- The higher US 18+ rate only applies to eligible spend from verified players who are 18 or older in the United States, not to every sale.
- Balances earned before September 5, 2025 cash out at the older rate first.
Only Earned Robux count for DevEx. Robux you bought with money cannot be cashed out.
Rates and what to verify
Checked on October 11, 2026 against Roblox's pages: the Developer Exchange page and the marketplace fees page.
- TO VERIFY: The 30% fee is confirmed on Roblox's page for Limited item sales and for avatar items bought inside a game. Roblox's pages for game passes and developer products did not state the percentage when checked, so confirm it on your own sales screen. That is why the fee box is editable.
- TO VERIFY: For avatar items sold on the Marketplace, the creator's share rises with the price (30% at the minimum price up to 70%). This calculator uses a flat fee, so it does not model that.
- TO VERIFY: DevEx rates and requirements can change. Check the official page before you cash out.
Things to watch out for
Sales can take time to show up, because Roblox may hold earnings for a while. Be careful of websites or videos that promise free Robux or ask for your password. Those are scams, and no real tool needs your login. If you are not sure about something, ask a parent or guardian. For more everyday math, try the percentage calculator or the seller fee calculators.
