Buying and cashing out are different
Robux have two very different dollar values. Buying them costs roughly $0.008 to $0.011 each depending on the package. Selling them back through DevEx pays $0.0038 per Earned Robux at the standard rate. That gap is why Robux are worth far less when cashed out than when bought.
On top of that, creators only receive 70% of what players spend on passes and products. A buyer who spends 1,000 Robux sends 700 to the creator; see the Robux tax calculator for the math.
How to read the results
The DevEx figure is what your Robux would pay out if they were Earned Robux and you met the requirements. The buy-cost figures show what the same amount would cost at the best-value and worst-value web store packages, listed in the table below. The last line works backwards: enter the dollars you want and see the Earned Robux needed.
Package sizes and prices change by region, platform and promotion, so treat the buy cost as an estimate and check the Roblox Robux store before purchasing.
Popular conversions
Common amounts have their own pages: 1,000 Robux to USD, 10,000 Robux to USD, 30,000 Robux to USD and 100,000 Robux to USD. Going the other way, see how much Robux $10 buys.
Cashing out
To turn Earned Robux into money you need at least 30,000 of them and a DevEx account. The DevEx calculator covers the three rates and the cash-out order.
