Enter any gross sale amount and it instantly shows the 30% fee Roblox keeps, the 70% you keep as earned Robux, and what that amount is worth in US dollars at the current 2026 DevEx rates. Updated for October 2026. Bookmark this robux tax calculator to price every game pass and developer product with confidence.
What Is the Robux Tax? The 30% Marketplace Fee Explained
The “Robux tax” is the nickname developers use for Roblox’s marketplace fee. Since April 2020, Roblox has taken a flat 30% cut from every game pass and developer product sale, and the fee is the same for all sellers. Before that change, sellers without Premium paid a fee of around 90%, so the current system is far friendlier to new developers.
Who pays the fee? The seller pays it. The buyer always pays the full listed price, and the fee comes out of your share. If a player buys your 500 Robux game pass, they spend 500 Robux and 350 Robux land in your account. The missing 150 Robux is the marketplace fee.
What sales does it apply to? Game passes and developer products sold in your experience. These are the two main ways developers sell items to players, and both use the same 70/30 split: you keep 70%, Roblox keeps 30%.
Why it matters for pricing: Work backwards from what you want to earn. To net 1,000 Robux from your sales, you need about 1,429 Robux in gross sales (1,000 divided by 0.70). Many developers learn this the hard way after setting prices based on the full list price. Use the robux tax calculator below to run these numbers for any price instantly.
How the Robux Tax Calculator Math Works
This robux tax calculator runs three simple steps on every sale:
- Marketplace fee: gross Robux x 0.30
- Earned Robux kept: gross Robux x 0.70
- USD value: earned Robux x your selected DevEx rate
Worked example: A player buys your game pass for 1,000 Robux. Roblox takes a 300 Robux fee (1,000 x 0.30), leaving you with 700 earned Robux (1,000 x 0.70). At the standard DevEx rate of $0.0038, those 700 Robux convert to $2.66 (700 x 0.0038). The robux tax calculator confirms the same result — enter 1,000 and it shows a 300 Robux fee, 700 kept, and $2.66.
Here is what common sale prices look like after the fee at the standard $0.0038 rate. Every row below matches what the robux tax calculator shows:
| Sale price | 30% fee | You keep | USD value |
|---|---|---|---|
| 100 Robux | 30 | 70 | $0.27 |
| 500 Robux | 150 | 350 | $1.33 |
| 1,000 Robux | 300 | 700 | $2.66 |
| 5,000 Robux | 1,500 | 3,500 | $13.30 |
| 10,000 Robux | 3,000 | 7,000 | $26.60 |
If your Robux were earned before September 5, 2025, switch the robux tax calculator to the legacy $0.0035 rate. Those older balances still cash out at the old rate first, per Roblox’s DevEx rules.
Turning Kept Robux Into Real Money: The DevEx Step
The Robux left after the marketplace fee are earned Robux, and they are the only kind you can convert to real money. Robux you bought from the store, received as a gift, or got from a Premium stipend can never be cashed out.
Conversion happens through Roblox’s Developer Exchange (DevEx) program. The 2026 rates are:
- $0.0038 per earned Robux (standard, for Robux earned on or after September 5, 2025)
- $0.0035 per earned Robux (legacy, for Robux earned before September 5, 2025, cashed out first)
- $0.0054 per earned Robux (US 18+ tier, since June 8, 2026, only for qualifying spend by age-verified 18+ US players in eligible experiences)
You need at least 30,000 earned Robux (about $114 at the standard rate) to request a cashout, plus a verified email, tax forms on file, and an account in good standing. To convert bigger balances in both directions, use our roblox devex calculator. If you are a player rather than a seller, our robux to usd calculator covers the buy side (1 Robux = $0.0125).
The bottom line on pricing: after the 30% fee and DevEx at the standard rate, every 1 Robux of sale price is worth about $0.00266 to you (0.70 x 0.0038). A 1,000 Robux game pass nets you roughly $2.66 in real money, while the player paid about $9.99 for that Robux. The robux tax calculator above shows this gap for any price, so use it before you set yours.
Robux Tax Calculator: Frequently Asked Questions
Who pays the 30% Roblox marketplace fee, the buyer or the seller?
The seller pays it. The buyer always pays the full listed price. If your game pass costs 500 Robux, the player spends 500 Robux and you receive 350. The fee never shows up as an extra charge to the buyer.
Is the 30% fee different for Premium members?
No. Since April 2020 the marketplace fee has been a flat 30% for every seller. Before that change, sellers without Premium paid around 90%, which is why older guides mention a much higher fee.
Can I cash out Robux I bought from the store or received as a gift?
No. Only earned Robux qualify for DevEx. Robux from direct purchases, gift cards, Premium stipends, and item trading or resale are not eligible, no matter how large the balance.
What is the difference between the marketplace fee and the DevEx rate?
They are two separate cuts at two separate steps. The marketplace fee is Roblox’s 30% cut taken in Robux at the moment of sale. The DevEx rate ($0.0038 standard in 2026) is the conversion rate applied later when you exchange your earned Robux for US dollars. Both reduce what you finally receive, which is why this calculator shows both.
Is the Roblox tax 40%?
No. The standard Roblox marketplace fee is a flat 30% on every game pass and developer product sale. Figures like 40% (or even 90%) come from the pre-April-2020 rules, when sellers without Premium lost around 90% of each sale. Since April 2020, every seller pays the same 30% fee. Plug any price into the robux tax calculator above to see the 30% fee in action.
Why do people say Roblox takes 70%?
They are flipping the split. Roblox takes 30% and the creator keeps 70%, so on a 100 Robux sale, 30 Robux go to Roblox and 70 Robux go to you. Anyone saying “Roblox takes 70%” has the numbers backwards.
Can I use this robux tax calculator for DevEx calculations?
Not directly — DevEx is a separate step that happens after the marketplace fee is taken. This robux tax calculator covers the 30% fee at sale time; cashing out runs through Roblox’s Developer Exchange program at the 2026 standard rate of $0.0038 per earned Robux, with a minimum of 30,000 earned Robux per request. For the cashout math, use our roblox devex calculator.
Does this work for Premium Payouts?
No. Premium Payouts are calculated from Premium subscriber engagement time in your experience, not from item sales, so the 30% marketplace fee does not apply to them.
