Robux to USD converter (and USD to Robux)

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 more generous amounts when buying on the Roblox website instead of in-app. The DevEx rate is what Roblox pays developers when they cash Robux out: $0.0038 per Robux, or $380 per 100,000 Robux (the standard rate since September 5, 2025). Type Robux and the tool shows dollars; type dollars and it shows Robux, rounded to the nearest whole Robux the way Roblox would grant them.

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. Both rates were re-checked against Roblox's own pages on October 15, 2026: the logged-out Robux purchase page still lists 800 Robux for $9.99 as the app-store base amount (1,000 on the web), and the Developer Exchange documentation still quotes $0.0038.

Robux to USD reference table

The amounts people ask about most, worked three ways. Costs to buy is the amount times the $9.99 / 800 base rate — exactly what the purchase mode above prints. DevEx pays is the amount times $0.0038, but only once a creator holds the 30,000 Earned Robux minimum, so smaller amounts read "below minimum". Resale nets is what a seller keeps after Roblox's 30% marketplace fee, in Robux, with its DevEx value in brackets — the fee comes off before the Robux ever become earned. Cheapest on the web is what a buyer actually pays: the cheapest set of whole web or gift-card packages that reaches the amount, with the Robux it delivers in brackets (explained below the table).

Figures use the $9.99 → 800 Robux app-store base tier ($0.0124875 per Robux, displayed as $0.0125), the DevEx rate of $0.0038, and the 30% fee, all from the constants file. The 1 Robux resale cell is 0.7 Robux rounded to a whole number, as the tools display it. "Below minimum" amounts would be worth the same $0.0038 each if they were part of a larger eligible balance — 10,000 Robux inside a 40,000 cashout is $38.00 of it.

What a number of Robux actually costs

The "Costs to buy" column prices Robux at a smooth rate, which is the right way to value a balance and the wrong way to price a purchase, because Roblox sells Robux only in whole packages. The last column answers the buyer's question. It searches the nine web and gift-card packages on Roblox's own Robux page (read again on October 15, 2026, unchanged since September 16) for the cheapest set whose Robux add up to at least the amount.

Three things stand out. Small amounts cost more than the smooth rate says, because the smallest package is $2.99 for 270 Robux: 1 Robux and 100 Robux both cost $2.99. Round amounts cost less, because web packages carry up to 25% more Robux than the app-store base the smooth rate uses, so 1,000 Robux is one $9.99 package rather than $12.49. And the cheapest set is often not one package. 800 Robux is cheapest as three $2.99 packages, $8.97 for 810 Robux, $1.02 under the $9.99 package. 10,000 Robux costs $97.96 as $49.99 + $34.99 + $9.99 + $2.99, which delivers 10,145 Robux; the single $99.99 package delivers 11,000 for $2.03 more, so it is the better buy if the other 855 Robux will be used.

The search never stacks small packages to save a cent: each extra package has to save more than three cents to be chosen. Type any amount into the converter and the "Cheapest on the web" cell runs the same search. The Robux goal calculator does it over the app-store packs instead, for buyers who pay inside an app.

How much is $1 in Robux?

Going into Roblox, $1 buys 80 Robux at the base rate: 1 ÷ 0.0124875 is 80.08, and the converter rounds to 80. Coming out, a creator has to earn about 263 Robux for every $1 of DevEx payout (100,000 ÷ 380 = 263.16). So a dollar is 80 Robux on the way in and 263 Robux on the way out, and the ratio between the two rates is 3.29 to 1. The same arithmetic gives $5 → 400 Robux, $10 → 801, $20 → 1,602 and $100 → 8,008 at the base rate — the odd numbers appear because $9.99, not $10.00, buys the 800 exactly:

The second column is what the converter prints. The other two are what whole packages give: $20 buys one $19.99 package, 2,000 Robux on the web or with a gift card and 1,700 in an app (the in-app amount Roblox lists beside the same package), against the 1,602 the smooth rate implies. $1 buys no package at all.

Real purchases come in packs rather than at a smooth rate, and the larger packs are cheaper per Robux. The app-store tiers in the constants file, re-verified on the Roblox purchase page on October 15, 2026: 400 Robux for $4.99 ($0.0125 each), 800 for $9.99 ($0.0125), 1,700 for $19.99 ($0.0118), 4,500 for $49.99 ($0.0111), 10,000 for $99.99 ($0.0100) and 22,500 for $199.99 ($0.0089). Since November 26, 2024 the same money on the Roblox website or a gift card buys more — 500, 1,000, 2,000, 5,250, 11,000 and 24,000 respectively, "up to 25% more" in Roblox's words. The Robux bundle value tool ranks the packs per dollar.

Why the three numbers differ

Take 1,000 Robux. Buying it costs $12.49. A creator who earned it would need 29,000 more before DevEx pays anything, and even then it is worth $3.80. Selling a 1,000 Robux item on the marketplace returns 700 Robux to the seller, worth $2.66 at DevEx. Three prices for the same Robux, because Roblox takes a margin at each step: the spread between the buy rate and the cash-out rate is the platform's, the 30% fee funds the marketplace, and the DevEx rate is applied to what is left after that fee, not to the original sale. None of this is hidden (it is how the business works), but it is why "how much is my Robux worth" has no single answer. For a player the useful figure is the replacement cost; for a creator it is the DevEx column; for a trader pricing an item it is the resale column.

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. Not all Robux is DevEx-eligible — see the DevEx 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 $190.00 — that's $0.0038 × 50,000. Now switch to Purchase rate: 50,000 Robux at $0.0125 would cost you $624.38 to buy. That gap of $434.38 is Roblox's spread, on top of the 30% fee that already came out of each gamepass sale before the 50,000 landed in your balance.

What this converter cannot see

It works in US dollars at US app-store prices. Robux packs are priced per region and per storefront, so a purchase in another currency or on a console may not match the table; gift cards and website purchases grant more Robux than the app-store base used here, so real purchases can land above the "costs to buy" column. Sales tax or VAT on a purchase is not included, and neither are the processor fees and income tax that come off a DevEx payout. Pack boundaries matter too: you cannot buy exactly 1,000 Robux from the app store, only 800 or 1,700, so the smooth per-Robux figures here are a reference rate, not a receipt. On the cash-out side the converter ignores the 30,000 minimum (the DevEx calculator enforces it), the once-a-month cadence, and the older $0.0035 rate that still applies to Robux earned before September 5, 2025.

What a gift card is actually worth

A Roblox gift card denominated in dollars does not carry a Robux number, and no rate turns one into the other. Roblox's own terms are specific about the path: the card redeems into Roblox Credit at face value, "a $100 Gift Card will be redeemed for $100 in Credits", and that Credit then buys a fixed Robux package. The second step decides the answer, because packages come in nine sizes and a balance has to land on them.

That distinction matters more than it sounds. The reference table higher up this page prices Robux at a smooth $0.0124875 each, which is the right way to value a balance you already hold and the wrong way to price a card in your hand, because nobody sells Robux at a smooth rate. Ask that table what $25 buys and it says 2,002 Robux. Redeem an actual $25 card and you get 2,500.

The gap is the web bonus. Roblox's help pages state that buying "on the web, computers and with gift cards" grants up to 25% more Robux than the same money spent inside a mobile app, and the same article says the pricing is permanent rather than a promotion (checked September 16, 2026). The packages below already include that bonus; the app-store column shows what the identical dollar amount buys through an in-app purchase. One exception comes first: Roblox's redemption article says Amazon and Party Packs cards are denominated in Robux directly and cannot be redeemed for Credit, so those skip the package step and state their own Robux figure on the card.

The packages a gift card can buy

Nine packages, read from Roblox's own purchase page on September 16, 2026 and unchanged on October 15, 2026. The bonus column is the interesting one, because "up to 25%" is a ceiling rather than a rate: the $4.99, $9.99 and $14.99 packages reach it, while the largest package adds 6.7%.

That has a consequence most buying advice gets backwards. On the app-store ladder the biggest pack holds the best per-dollar rate, even though the $0.99 tier edges out the $9.99 one. On this ladder the biggest still wins overall, 120.01 Robux per dollar at $199.99 against 90.30 at $2.99, but the middle is not ordered the way you would expect: the $4.99 package returns 100.20 Robux per dollar and the $19.99 package returns 100.05, so four small packages edge out one larger one. The margin is too thin to plan around, but it is real, and it is why the calculator searches combinations instead of assuming bigger is better.

Gift card and Roblox Credit table

Every row is the best combination of packages the credit can buy, computed by the same script that runs the calculator above. These are credit amounts, not a list of the card denominations Roblox sells; the limitations below explain why this page does not print one.

Read the last column rather than the Robux column. From $5 to $30 the rate is a flat cent per Robux, because those balances land cleanly on packages. Above that it moves for reasons that have nothing to do with generosity: $50 buys at $0.00952 per Robux, but $40 buys at $0.00970 and $75 at $0.00968, because neither amount reaches the next package without waste. The worst row is $150 at $0.00923, a worse rate than $100 at $0.00909, purely because $150 cannot reach the $199.99 package and has to buy the $99.99 and $49.99 ones instead. A bigger card is not automatically a better price.

Worked example: a $25 gift card

Redeem it and the account shows $25.00 of Roblox Credit. The best the balance can do is the $19.99 package plus the $4.99 package: 2,000 + 500 = 2,500 Robux for $24.98, leaving $0.02 stranded. Divide the face value rather than the amount spent, because those two cents are gone either way: 25 ÷ 2,500 = $0.01000 per Robux.

Three numbers can be put on the same 2,500 Robux. Buying them at the app-store base rate would cost 2,500 × $0.0124875 = $31.22. The card did it for $25. If those 2,500 Robux had been earned rather than bought, DevEx would pay 2,500 × $0.0038 = $9.50, and not on their own, since the minimum cashout is 30,000 Earned Robux. So the card is worth 2,500 Robux, or about a quarter more than the smooth rate at the top of this page implies, which works out to one cent per Robux. What it is not worth is $25 of anything else: Credit buys Robux and Roblox services, cannot be split with another payment method, and has no cash value.

When the largest package is not the best buy

Roblox's redemption page pre-selects "the largest package you can purchase with your Credit balance". That is a sensible default and it is usually right, but it is not always right, and the calculator shows both answers so you can see when they part company.

The cleanest case is a $5.98 balance, which is what two $2.99 cards or an odd remainder leaves. The largest affordable package is the $4.99 one: take it and you hold 500 Robux with $0.99 stranded. Two $2.99 packages instead return 540 Robux and strand nothing. Forty Robux is not a scandal, but it is 8% more for the same money, and the default hands it back. Across every whole-cent balance from $0.01 to $200.00, the pre-selected choice returns fewer Robux than the best combination 9,822 times, and the widest gap is 270 Robux. The pattern is always the same: a large package eats the balance and leaves a remainder too small to buy anything.

What this page does not list about gift cards

There is no denomination table here, because Roblox does not publish one anywhere this site can reach: roblox.com/giftcards returned a 404 on September 16, 2026, the gift-card shop page loads its catalogue with JavaScript and ships no values in the HTML, and the help article titled "Where Can I Find Roblox Gift Cards?" names retailers and nine countries without listing a single face value. Two US retailers did list cards that day, GameStop showing $10 through $200 and Newegg $25 through $200, agreeing on $25, $50, $100 and $200. Retailer listings are not Roblox's word on what exists, and the rule here is that a figure gets published only when two current sources agree with the platform's own page among them. So the tool takes whatever number is printed on your card.

Other things stay out for the same reason. Roblox documents a "Convert Credit to Robux" button for a remainder too small to buy a package but publishes no rate for it, so the tables show that money as stranded instead of guessing. Figures are US dollars at US pricing; other countries convert at rates Roblox says it refreshes monthly, and sales tax on a Credit purchase depends on your state. The bonus is discretionary, with the terms reserving the right to discontinue it without notice, so every number here is dated September 16, 2026 rather than permanent.
