Robux Tax Calculator: 30% Fee, DevEx, Pls Donate, and Rounding
This robux tax calculator exists because every Roblox seller learns it the hard way: list at 1,000 Robux and you keep 700, because Roblox takes 30% of every sale. Want 1,000 to land in your balance? You have to list at 1,429.
Four modes, one box. Nothing is saved.
How do you use the robux tax calculator?
Pick a mode, then type either the amount you want to receive or the price you plan to list at:
- Standard 30%: UGC items, game passes, developer products and Limited resales
- Pls Donate 40%: donations inside Pls Donate, where the game takes its own cut on top
- DevEx (USD): what a listing turns into in dollars after the fee and the cash-out rate
- Trader / Ad: break-even prices for flipping Limiteds or getting back what you spent on ads
Standard marketplace: 30% Roblox fee. Works for UGC, game passes, dev products, limited resales.
The calculator rounds the way sellers actually get paid, down to whole Robux, so it also shows the effective tax rate on small prices, which is often above 30%.
Rather watch someone run the numbers? This video walks through the same formulas, from the listing price to what lands in your balance.
How does the 30% fee in the robux tax calculator work?
Roblox keeps 30% of every marketplace sale. Flat. It is not tiered, Premium doesn’t lower it, and there is no way to negotiate it. The fee applies to:
- UGC items: hats, faces, clothing, accessories and bundles
- Game passes and developer products sold inside experiences
- Limited resales, every time the item changes hands through a sale
- Private servers and paid-access experiences
- Models, plugins and audio sold on the Creator Store
Not taxed: direct trades and Premium stipends.
Two formulas cover nearly everything: you receive = FLOOR(listing x 0.70), and list at = CEIL(target / 0.70). For mental math, multiply your target by 1.43 and you will be within a Robux or two.
Why does the robux tax calculator show more than 30% on small sales?
Because fractions of a Robux get dropped. On a 1,000 R$ sale that changes nothing at all, since 70% of 1,000 is a whole number. On a 5 R$ hat? A lot.
| Listing price | 70% of it | You receive | Effective tax |
|---|---|---|---|
| 2 R$ | 1.4 | 1 R$ | 50% |
| 3 R$ | 2.1 | 2 R$ | 33.3% |
| 5 R$ | 3.5 | 3 R$ | 40% |
| 10 R$ | 7.0 | 7 R$ | 30% |
| 15 R$ | 10.5 | 10 R$ | 33.3% |
| 100 R$ | 70.0 | 70 R$ | 30% |
Multiples of 10 always come out clean (10, 20, 50, 100), because 70% of each is already a whole number of Robux. The rounding also creates dead steps. List at 16 R$ and you get 11. List at 17 R$ and you still get 11, so the extra Robux only costs your buyer. The calculator skips those.
Robux tax calculator cheat sheet: what to list at

| 100 R$ | 143 R$ | 43 R$ |
| 250 R$ | 358 R$ | 108 R$ |
| 500 R$ | 715 R$ | 215 R$ |
| 1,000 R$ | 1,429 R$ | 429 R$ |

| 10,000 R$ | 14,286 R$ | 4,286 R$ |
How does Pls Donate tax donations?
Pls Donate adds its own 10% on top of Roblox’s 30%, so the person receiving a donation keeps 60%. A 1,000 R$ donation splits into 300 R$ for Roblox, 100 R$ for the game and 600 R$ for the recipient.
The formula is FLOOR(donation x 0.60). To make sure a friend keeps exactly 100 R$, donate CEIL(100 / 0.6), which is 167 R$. Pls Donate mode in the calculator shows the full split.
How does the robux tax calculator handle DevEx?
The Developer Exchange (DevEx) lets you cash out Earned Robux, and the order matters: the 30% fee hits first, then the DevEx rate converts what is left. The calculator uses the standard rate:
- $0.0038 per Earned Robux for Robux earned from September 5, 2025 (up from $0.0035, about 8.6% more)
- $0.0035 for Robux earned before that date, which still cash out at the old rate
- Since June 8, 2026, a higher $0.0054 rate applies to eligible spending by age-verified US players aged 18 or older. It covers part of your earnings, not the whole balance, so the calculator’s standard rate is the safe lower estimate.
To qualify you need at least 30,000 Earned Robux, an age of 13 or older, a verified email, an account in good standing and a DevEx portal account. Only Earned Robux count: game pass and item sales do, but Robux you bought or got as a Premium stipend don’t.
| Earned Robux | At $0.0038 | At $0.0035 |
|---|---|---|
| 30,000 (minimum) | $114 | $105 |
| 50,000 | $190 | $175 |
| 100,000 | $380 | $350 |
| 250,000 | $950 | $875 |
| 1,000,000 | $3,800 | $3,500 |
A full example: list at 10,000 R$, Roblox takes 3,000, you keep 7,000 Earned Robux, and DevEx at $0.0038 turns that into $26.60. Put simply, a dollar of DevEx income costs about 376 R$ in gross sales at the standard rate.
How do you work out break-even for flips and ads?
Thing is, both follow the same math, because both get their Robux back through taxed sales.
Flipping a Limited. Buy at 5,000 R$ and you need 5,000 back after the fee, so the break-even price is CEIL(5,000 / 0.7) = 7,143 R$. The classic mistake: buy at 800, sell at 1,000, feel 200 up. You actually received 700, a 100 R$ loss.
Ads. Spend 1,000 R$ on ads and your sales need to reach 1,429 R$ gross before you even break even. Profit only starts above that.
Trades are the one way around the fee. A direct swap of items, or items plus Robux, between two players isn’t a listed sale, so neither side pays 30%. The catch is that both accounts need Premium with trading switched on, only trade-eligible items qualify, and scammers love trades. UGC items, clothing and game passes can’t be traded at all. And if a trade partner asks you to send Robux first or to finish the deal somewhere outside Roblox, walk away, because that is exactly how most trade scams start.
How should creators price with the 30% fee in mind?
UGC accessories. Small prices suffer most from rounding, so pick prices that land on whole numbers after the fee: 10, 20, 30, 50, 100.
Game passes. In practice, a pass priced at 100 R$ pays 70. If you need 100, price it at 143. Some developers keep round prices on purpose because a player with exactly 100 Robux will buy a 100 R$ pass and not a 143 R$ one. Fair enough, as long as you choose that knowingly.
Collabs. Revenue splits with other creators happen after Roblox’s 30%. Sell something for 100 R$ and split it evenly, and each of you gets 35, not 50. Nobody expects that until they see the deposit.
Is 30% a lot compared to other platforms?
It is mid-pack. Apple’s standard App Store cut and the Unity Asset Store also take 30%, while the Epic Games Store takes 12%. Steam’s paid mods experiment in 2015 left creators 25%. Pulled within days. Look, nobody likes handing over 30%, but if you have been selling on Roblox long enough you just bake it into every price and stop thinking about it.
