If you sell game passes, catalog items, or take donations on Roblox, the amount buyers pay is not the amount you keep. Creators call that gap Robux tax — Roblox’s marketplace fee. This 2026 guide explains how the fee works, walks through real examples (including how much is 400 Robux with tax), and shows how to use a free Robux tax calculator so your list prices match what you actually want to receive.
Open the free tool anytime: Robux Tax Calculator. It is built for the questions players type every day — Robux calculator tax, free Robux calculator, Robux counter-style checks, and Pls Donate payout math — without asking for a login.
What “Robux tax” means on Roblox
Robux tax is the common name for Roblox’s marketplace fee on creator sales. When someone buys your game pass, developer product, or many marketplace listings, Roblox keeps a percentage of the list price and credits you the rest. In everyday creator math for 2026, that fee is treated as about 30%, so you keep roughly 70% of the listed Robux.
That is why a pass priced at 100 Robux does not put 100 Robux in your wallet. After tax you receive about 70 Robux. The buyer still pays 100; the platform fee sits between the list price and your payout.
Tax here is not a government income tax on your Roblox account. It is platform economics — the cost of selling through Roblox’s official purchase systems. Understanding it matters for gifts, UGC pricing, and donation booths alike.
Why you need a Robux tax calculator in 2026
Guessing fees in chat leads to short gifts and awkward follow-ups. A Robux tax calculator 2026 does two jobs cleanly:
- Before → after: enter a list price and see tax plus what you keep.
- Target → list price: enter the Robux you want to keep and get the list price to publish.
BloxBuzz’s free Robux calculator handles both directions in the browser. Use it before you publish a gift pass, update a Pls Donate stand price, or agree on a “send me 400” deal with a friend.
How to use the free Robux Tax Calculator
- Go to the Robux Tax Calculator.
- Type the list price (what the buyer pays) to see Robux after tax and the tax amount.
- Or type the Robux you want to keep in the “desired after tax” field to see the list price you should set.
- Copy that list price into your game pass, product, or booth listing.
- Remind the recipient that earnings may show as pending Robux before they become spendable.
No account, no install, no “free Robux” scam pitch — just fee math you can verify yourself.
How much is 400 Robux with tax?
This is one of the most searched Robux tax questions, so here is the clear answer for the standard 30% fee model:
- If the list price is 400 Robux, tax is about 120 Robux, and you keep about 280 Robux after tax.
- If you want to receive 400 Robux after tax, list about 572 Robux (400 ÷ 0.70), because 30% of 572 is roughly 172 and 70% lands near 400.
So “how much is 400 Robux with tax?” depends on which side you mean: paying 400, or netting 400. Always say “400 after tax” or “400 list price” when you negotiate. Then confirm the number in the Robux tax calculator before anyone clicks Buy.
Quick Robux tax examples (list price → you keep)

Robux calculator, Robux counter, and tax — what people mean
Search phrases overlap, but they are not identical:
- Robux calculator tax / Robux tax calculator — fee math: before tax, after tax, and list price for a target net. That is what our tool is for.
- Free Robux calculator — usually means a no-paywall fee or conversion tool, not a generator that creates Robux out of thin air. Legitimate calculators never ask for your password.
- Robux Calculator / Robux Counter — often shorthand for counting how much you keep after a sale, or tracking totals. Treat “counter” as a check of amounts, not a cheat.
If a site promises unlimited free Robux from a “calculator,” close it. Real Robux come from official purchases, creator earnings, and verified in-game codes — not from fake counters.
Pls Donate Robux calculator: pricing booths the smart way
Pls Donate (and similar tip/donation experiences) is where fee confusion shows up most. A donor may think they sent 1,000 Robux while you only see ~700 after platform fees. A Pls Donate Robux calculator mindset is simple: decide the net you want, then raise the pass or product price so 70% equals that net.
Example: you want ~700 after tax → list 1,000. You want ~400 after tax → list ~572. Put the intended net in the pass name (“Gift 400 after tax”) so donors and friends stop arguing about before vs after. Pair the calculator with our Pls Donate codes page when you are hunting promo rewards — codes are separate from tax math, but both belong in a creator’s weekly checklist.
USD to Robux calculator vs Robux tax calculator
People also search for a USD to Robux calculator (and Robux to USD). That answers a different question: rough cash value or package comparison, not marketplace fee on a sale.
- Use the Robux Tax Calculator when you care about list price vs creator payout.
- Use the Robux to USD converter when you care about approximate dollar value of a Robux balance (for example DevEx-style planning).
Do not mix the two in one chat message. “How much is 400 Robux?” can mean USD value, list price, or after-tax payout. Clarify the unit, then open the matching BloxBuzz tool.
Gifting friends without shorting the payout
Roblox has no direct “Transfer Robux” button. Friends usually gift by buying a game pass. Price that pass with tax in mind or the recipient receives less than you both expected. Full walkthrough: how to send Robux. After the purchase, remind them about pending Robux clearance before they spend.
Common mistakes when estimating Robux tax
- Agreeing on “400 Robux” without saying after tax or list price.
- Publishing a pass at the desired net amount instead of the grossed-up list price.
- Forgetting pending holds and thinking the fee calculator is “wrong.”
- Trusting third-party “free Robux calculator” pages that ask for credentials.
- Using old screenshots from years ago when fee messaging or UI labels looked different — re-check with a current Robux tax calculator 2026 run.
Safe habits around Robux tools
A helpful calculator never needs your Roblox password, authenticator codes, or cookie dumps. Bookmark BloxBuzz tools on your own device. Buy Robux only through official Roblox channels. Treat Discord bots that “verify” tax or boost pending as scams.
