Robux to USD converter
Type either side and see the other. Toggle between the in-store purchase rate and the DevEx cashout rate — they're very different numbers.
How the Robux to USD converter works
Roblox uses two completely different exchange rates depending on whether money is going into the platform or coming out. The purchase rate is what Roblox charges you to buy Robux in the store — about $0.0125 per Robux at the $9.99 / 800 Robux tier, with small discounts at higher tiers and through Premium. The DevEx rate is what Roblox pays developers when they cash Robux out: $0.0035 per Robux, or $350 per 100,000 Robux.
The spread is intentional. Roblox keeps a healthy margin on every Robux that enters the system, which is what makes the platform work as a business. For a player or trader, though, the rates matter for two different scenarios: deciding whether a Robux purchase is worth it, and deciding whether the gamepasses or dev products you've sold add up to a worthwhile cashout. This tool flips between those two views with the radio buttons at the top of the calculator.
The numbers in this calculator pull from a single constants file on this site
(/assets/js/lib/roblox-constants.js) so every tool that touches Robux uses the
same rate. If Roblox updates either rate, that file moves and everything on the site
follows.
You'll see this tool called a few different things — a Robux to dollars converter, a Robux to money converter, a Robux to cash calculator, or just a Robux exchange-rate calculator. They all do the same job: take a Robux amount and show what it's worth in real US dollars, both to buy and to cash out.
When to use it
- Sanity-checking a Robux purchase. Before you tap "buy" on a Robux bundle, type the bundle's USD price in to see how many Robux you'd actually be getting at the base rate. Larger bundles save a few percent.
- Setting expectations for DevEx. If you're a developer or group owner with Robux on the books, the DevEx side tells you what that balance is actually worth in real money. Note: not all Robux is DevEx-eligible — see the Cashout Calculator for the rules.
- Pricing a trade against real-money equivalents. Some traders use the DevEx rate as the floor for what an item is "really worth." It's a flawed measure, but it's a useful sanity check.
Worked example
You've earned 50,000 Robux from gamepass sales and want to cash out. Switch to DevEx rate, type 50,000 into the Robux input, and the USD field shows $175 — that's $0.0035 × 50,000. Now switch to Purchase rate: 50,000 Robux at $0.0125 would cost you $625 to buy. That gap of $450 is Roblox's spread, the marketplace fee already taken on the way in, and the 30% take rate that came out of the sale.
Robux to USD conversion table
Quick reference for the amounts people convert most often. "Costs to buy" is what that many Robux would cost you in the store at the base rate; "DevEx cashout" is what a developer or group owner receives for cashing the same amount out.
| Robux | Costs to buy (USD) | DevEx cashout (USD) |
|---|---|---|
| 100 Robux | $1.25 | $0.35 |
| 400 Robux | $5.00 | $1.40 |
| 800 Robux | $9.99 | $2.80 |
| 1,000 Robux | $12.49 | $3.50 |
| 1,700 Robux | $21.23 | $5.95 |
| 2,000 Robux | $24.98 | $7.00 |
| 4,500 Robux | $56.19 | $15.75 |
| 5,000 Robux | $62.44 | $17.50 |
| 10,000 Robux | $124.88 | $35.00 |
| 17,000 Robux | $212.29 | $59.50 |
| 22,500 Robux | $280.97 | $78.75 |

| 40,000 Robux | $499.50 | $140.00 |
| 50,000 Robux | $624.38 | $175.00 |
| 100,000 Robux | $1,248.75 | $350.00 |
Going the other way — how much Robux a dollar amount buys at the base store rate:
| USD | Robux (at purchase rate) |
|---|---|
| $1.00 | 80 Robux |
| $5.00 | 400 Robux |
| $10.00 | 800 Robux |
| $20.00 | 1,600 Robux |
| $25.00 | 2,000 Robux |
| $50.00 | 4,000 Robux |
| $100.00 | 8,000 Robux |
Figures use the $9.99 → 800 Robux base tier ($0.0125/Robux) and the DevEx rate of $0.0035/Robux. Larger store bundles and Premium give a small bonus, so real purchases can land slightly above these numbers.
FAQ
Is the purchase rate exactly $0.0125 per Robux?
The $9.99 → 800 Robux tier works out to exactly $0.012487… per Robux. Larger purchase tiers (the $99.99 → 10,000 Robux pack and up) carry a small bulk discount, so the effective rate drops a bit. Premium members get a 10% bonus on Robux purchases on top of that. This calculator uses the base tier as the reference because that's the price most casual buyers actually see.
Why is DevEx so much lower than the purchase rate?
Roblox needs a wide margin between buy and sell to fund payouts, hosting, moderation, and platform development. Every Robux earned in the system has already had the 30% marketplace fee taken out, so the DevEx rate is the rate on what's left after that fee — not on the original sale.
Can I withdraw Robux that I bought?
No. Only Robux earned through developer or group payouts is DevEx-eligible. Robux you bought directly stays inside the platform.
What's the minimum DevEx cashout?
50,000 Robux at the time of writing. Below that, you can't initiate a DevEx withdrawal. See the DevEx Cashout Calculator for thresholds and eligibility notes.
