Robux Price Calculator

$9.99 on roblox.com. In the iOS or Android app $9.99 buys only 800 Robux, so 1,000 Robux there means the $19.99 package (1,700 R$) or two smaller ones — the calculator finds the cheapest route. Larger web packages cost less per Robux: 1.0¢ each in the $9.99 pack, 0.83¢ in the $199.99 pack.

About $100 on the web: the single $99.99 pack gives 11,000 R$, while two $49.99 packs give 10,500 R$ for $99.98 — a cent less but 500 fewer Robux, so the calculator recommends the single pack and shows the overshoot. In the app 10,000 Robux is exactly the $99.99 package.

Buy on the website rather than in the app (the same $9.99 gives 1,000 R$ instead of 800), and buy the largest package you will actually use: the $199.99 web pack is 17 % cheaper per Robux than the $4.99 pack. Gift cards from retailers sometimes come with bonus items but redeem at the standard rate; third-party “cheap Robux” sellers violate the terms of service.

No. Roblox Plus ($4.99 a month, launched April 30, 2026) replaced Premium and has no monthly stipend. It gives 10 % off in-experience and avatar purchases, so your Robux go about 11 % further when spent — worth it if you spend more than roughly 50 dollars of Robux a month, not if you mainly buy passes occasionally. Tick the Plus box above to see the effect.

Robux are a digital good; most US states and many countries charge sales tax or VAT on the package price, added at checkout. The prices here are the advertised pre-tax amounts.
