You want to pay a friend exactly 500 Robux for their work on your game. Or you promised a group member a specific payout. Or you are commissioning an artist and agreed on a set amount. Whatever the situation, you need someone to receive a precise number of Robux — and you are not sure how much you need to send to make that happen.
This is one of the most searched questions in the Roblox creator community, and the answer requires understanding exactly how the Roblox marketplace tax works on outgoing transactions. This guide will give you the complete answer, the formula, a reference table covering the most common amounts, and worked examples for the most typical real-world scenarios.

Why the Amount You Send Is Not the Amount They Receive
Roblox applies a 30 percent marketplace fee on most transactions that move Robux through the platform. This means that when Robux flows from a buyer to a seller — whether through a game pass purchase, a developer product sale, or a group payout scenario — Roblox keeps 30 percent and passes on 70 percent.
The fee is always calculated on the gross amount — the full transaction value — not on your intended net payment. This is a critical distinction. The 30 percent is not taken from the receiver’s end as a flat deduction after you send a specific amount. It is built into the transaction structure itself, which means you need to gross up your intended payment to account for it.
⚠ You Cannot Simply “Add 30 Percent” to Gross UpA very common mistake is thinking that to cover the 30 percent tax, you just add 30 percent to the amount you want them to receive. This is wrong and will always leave the receiver short. The correct grossing-up factor is dividing by 0.70, not multiplying by 1.30. These produce different results, and only one is correct.
Here is why that matters with a concrete example:
- You want someone to receive 700 Robux.
- Wrong approach: 700 × 1.30 = 910 Robux. After 30% tax on 910: receiver gets 637 Robux. Still short.
- Correct approach: 700 ÷ 0.70 = 1,000 Robux. After 30% tax on 1,000: receiver gets 700 Robux. Exactly right.
The difference between 910 and 1,000 Robux is 90 Robux — meaning the wrong approach would leave your recipient 63 Robux short of what you intended, every single time.
The Correct Formula
The formula to calculate how much needs to be charged or sent so that someone receives a specific amount is always the same:
Amount to Charge / Send = Desired Received Amount ÷ 0.70
This works because if the gross amount is X, then 70 percent of X equals the net amount received. Rearranging that gives you X = net ÷ 0.70.
Memorize this formula or bookmark this page. It applies in every situation where you want to target a specific post-tax Robux amount.
Worked Examples for Common Scenarios
Scenario 1: Paying a Developer for Their Work
You agreed to pay a scripter 1,000 Robux for writing a game system. You set up a developer product or group payout. How much do you need to configure the transaction for?
1,000 ÷ 0.70 = 1,429 Robux
Set the payout or product price at 1,429 Robux. After the 30 percent fee, the developer receives approximately 1,000 Robux as agreed.
Scenario 2: Commissioning an Artist
You are commissioning a Roblox clothing designer for 250 Robux. You want them to receive exactly 250 Robux after any fees.
250 ÷ 0.70 = 358 Robux
Price the commission transaction at 358 Robux. The artist receives approximately 250 Robux after the platform deduction.
Scenario 3: Rewarding a Group Contributor
You want to give a loyal group member a 500 Robux bonus from the group fund. How much does the group payout need to be set to?
Note: as covered in our group payouts guide, the payout itself does not deduct an additional fee from already-earned group funds. If you enter 500 Robux in the payout field, the member receives 500 Robux — no grossing up needed for direct group payouts from existing funds.
However, if you are structuring the payment through a developer product purchase, the 30 percent fee applies and you would need to set the product at 715 Robux for the member to receive 500 Robux.
Scenario 4: Running a Giveaway
You are running a Roblox giveaway and want the winner to receive exactly 2,000 Robux. You plan to use a special developer product for them to claim it.
2,000 ÷ 0.70 = 2,858 Robux
Price the claim product at 2,858 Robux and purchase it on behalf of the winner (or have them claim it). After the fee, they receive approximately 2,000 Robux.

💡 Rounding NoteAll figures in the table above are rounded to the nearest whole Robux. In practice, Roblox only accepts whole number prices for game passes and developer products. When your calculation produces a decimal, always round up — not down — to ensure the recipient receives at least the intended amount.
The Difference Between Sending and Charging
It is worth clarifying something that confuses many creators: on Roblox you generally cannot send Robux directly to another player the same way you might send a text message. The platform’s economy is structured around transactions, not transfers. Here are the main legitimate ways Robux moves from one person to another and how the tax applies to each:
Via a Developer Product
The most common method for structured payments between players or collaborators. You create a developer product in your game priced at the grossed-up amount, and the intended recipient purchases it. After the 30 percent fee, they receive 70 percent of the product price. Use the formula or reference table above to set the correct price.
Via a Group Fund Payout
If both parties are members of a Roblox group and the funds are already sitting in the group balance — meaning the marketplace fee has already been deducted upstream — a direct group payout transfers Robux without an additional deduction. In this case, the amount you enter in the payout field is the amount the member receives, with no further grossing up needed.
Via Game Pass Purchase
Less common for payments, but a game pass can be set up for one-time commission or payment arrangements. The same 30 percent tax applies — the recipient receives 70 percent of the listed price. Price it using the same formula: desired amount ÷ 0.70.
⚠ Avoid Third-Party Transfer MethodsSome players attempt to transfer Robux through unofficial means — third-party websites, item gifting arrangements, or other workarounds that bypass the Roblox platform. These methods often violate Roblox’s Terms of Service and can result in account bans for both parties. Always use official Roblox mechanisms for any Robux exchange.
Why This Calculation Matters More for Larger Amounts
For small amounts the difference between the wrong and right grossing-up approach may seem trivial. But as the payment size grows, the gap between the correct and incorrect method becomes significant — and can create real friction in creator-to-creator working relationships.
| Intended Received Amount | Wrong Method (×1.30) | Receiver Actually Gets | Shortfall | Correct Method (÷0.70) | Receiver Actually Gets |
|---|---|---|---|---|---|
| 100 Robux | 130 Robux | 91 Robux | −9 Robux | 143 Robux | 100 Robux ✓ |
| 500 Robux | 650 Robux | 455 Robux | −45 Robux | 715 Robux | 500 Robux ✓ |
| 1,000 Robux | 1,300 Robux | 910 Robux | −90 Robux | 1,429 Robux | 1,000 Robux ✓ |
| 5,000 Robux | 6,500 Robux | 4,550 Robux | −450 Robux | 7,143 Robux | 5,000 Robux ✓ |
| 10,000 Robux | 13,000 Robux | 9,100 Robux | −900 Robux | 14,286 Robux | 10,000 Robux ✓ |
At a 10,000 Robux intended payment, using the wrong method leaves your recipient 900 Robux short. That is a significant underpayment that could damage a working relationship and require awkward follow-up corrections.

A Practical Checklist Before Any Robux Payment
Before you set up any transaction intended to pay a specific amount to another player or creator, run through this quick checklist:
- Decide the exact post-tax amount you want them to receive. This is your target, not the transaction amount.
- Identify which payment method you are using — developer product, game pass, or group fund payout — because group fund payouts from existing balances do not require grossing up.
- If using a developer product or game pass, apply the formula: target amount ÷ 0.70 = transaction price to set.
- Round up to the nearest whole Robux to ensure the receiver gets at least the intended amount.
- Confirm the transaction price before finalizing by checking it against the reference table or calculator.
Final Thoughts
Getting Robux payments right comes down to one fundamental principle: the 30 percent fee is applied to the gross transaction amount, so you must always gross up your intended payment using division by 0.70 — never by adding 30 percent to the net figure.
