Convert Robux to real USD — buy rate, DevEx rate, marketplace tax calculator
Robux value check
Buy cost, DevEx payout, and platform fee are different numbers.
Rate assumptions
The top Robux calculator pages separate purchase value from creator payout value. This page follows that pattern so users do not confuse what Robux costs to buy with what eligible creators may receive through DevEx.
Purchase estimate
$99.99 / 10,000 Robux
Used for the main buy-value estimate because it is the best listed rate in the table.
New DevEx rate
$0.0038 / Robux
Applies to eligible earned Robux after Roblox's Sep 5, 2025 rate update.
Old DevEx rate
$0.0035 / Robux
Useful for older earned Robux balances that still cash out at the old rate.
Marketplace fee
30%
Used to estimate creator earnings after sales of passes and developer products.

Robux costs more to buy than creators receive through DevEx, so the calculator shows both numbers separately.
Enter a dollar budget to estimate how many Robux it represents at the best listed web bundle rate.
For sales like passes and developer products, the after-fee Robux estimate uses a 30% marketplace fee.
DevEx rate updated Sep 5, 2025. Purchase estimates use listed Roblox web bundle pricing before regional prices, taxes, gift cards, subscriptions, or promotions.
For purchase value, the calculator multiplies your Robux amount by the best listed bundle rate in the table. For example, the 10,000 Robux bundle at $99.99 works out to about $10.00 per 1,000 Robux before taxes, region changes, gift cards, subscriptions, or promotions.
For DevEx, the calculator shows both the current $0.0038 per earned Robux estimate and the older $0.0035 rate. Roblox's support page says the new rate applies after 10:00 AM PT on September 5, 2025, while older earned Robux balances may continue using the old rate until cleared.
For marketplace sales, the calculator estimates a 30% fee first, then applies the DevEx rate to the remaining Robux. That makes it easier to compare a sale price, the Robux you keep, and the possible cash-out value.
