The Basic Conversion
A $10 purchase on Roblox gives you 800 Robux at the standard rate. That is the straightforward answer, but the actual amount you end up with depends on how you pay and whether you have an active subscription. Roblox has a few different purchasing paths, and they do not all give you the same number of Robux for the same dollar amount. If you are buying directly through the Roblox website or mobile app with a credit card, PayPal, or a Google Play/App Store purchase, you receive exactly 800 Robux for a $10 spend. That rate is fixed and does not change regardless of what region you are in. However, there are other ways to spend that same $10 that yield less. Gift cards are the main exception. A $10 Roblox gift card codes for $10 in Robux value, but that still equals 800 Robux. The issue most people hit with gift cards is the checkout process. If you try to redeem a gift card on a console or certain older app versions, the card sometimes applies as a balance rather than converting to Robux automatically. You have to manually go into the Robux purchase screen and confirm the transaction. I spent about twenty minutes trying to figure out why my $10 card was sitting in my account balance with zero Robux added. The fix was simply navigating to the Robux tab inside the app, clicking the 800 Robux option, and selecting my gift card balance as the payment method instead of treating the card as a standalone credit.
Another scenario that trips people up involves currency rounding and minor regional price adjustments. In some countries, a $10 equivalent might be rounded to the nearest local currency unit, which can shave off a few Robux or add a small surplus. It is not common, but it happens enough that your final count might read 795 or 805 depending on how the local payment processor rounds the conversion. If you have Roblox Premium, the math changes. Premium members get a 10% bonus on all Robux purchases, so spending $10 would net you 880 Robux instead of 800. That is the main advantage of the subscription beyond the monthly stipend of 1,000 Robux that Premium also includes. Without Premium, you are locked to the base rate. There is also the third-party reseller route. Some sites claim to sell Robux at cheaper rates, often quoting something like $7 for 800 Robux. These are unofficial, and the risk is real. Accounts caught buying from unauthorized resellers get banned. The money you might save is not worth losing the account. I know people who burned through fifty dollars on resold Robux and then watched their accounts suspended within a week. Stick to official channels.
Pitfalls and What People Miss
The most common mistake is confusing Robux value with spending power. 800 Robux sounds like a lot, but the price of items in the Roblox marketplace varies wildly. A popular accessory might cost 50 to 200 Robux. A limited item can go for thousands. If you are expecting 800 Robux to buy a premium outfit, you will quickly find yourself short. Another thing that catches people off guard is the difference between Robux and the premium currency used in certain games. Not every game accepts standard Robux. Some use internal tokens or game-specific currencies that you have to purchase separately. Buying 800 Robux will not help you in a game that requires its own separate token system. The mobile purchase route has its own quirks. If you buy through the Apple App Store or Google Play, you are subject to their billing policies. Apple, for example, does not always honor the direct Roblox rate and sometimes the transaction reflects a slightly different amount due to store-level pricing rules. If you notice your Robux balance does not match the expected 800 after an in-app purchase, check your receipt. A discrepancy usually means the store applied a different pricing tier or the transaction was partially processed.

Bottom Line
Eight hundred Robux for ten dollars is the standard. With Premium, it is 880. Gift cards work but require manual redemption in most cases. Third-party sellers are not worth the risk. And if your final count is slightly off, it is almost always a rounding or regional pricing issue rather than a bug in the system.
