Roblox tools & calculators
Every calculator, lookup and data page on BloxToolbox, grouped by type. All free, with no login or sign-up, and everything runs in your browser.
Economy 9
Convert Robux to US dollars at purchase or DevEx rates, and price a gift card: what a credit balance actually buys once it has to land on a Robux package.
Compare every Robux purchase bundle by Robux per dollar to find the best value pack before you buy.
Enter a target Robux amount and get the cheapest combination of purchase packs to reach it, with cost and leftover shown.
Flip math for limiteds: profit, ROI, and break-even after Roblox's 30% fee.
See the USD payout on a DevEx exchange and the minimum threshold.
Split a Robux pool across group members into whole Robux, with the rounding rule shown and each share's DevEx value. A payout is not taxed again.
Is Premium still worth it? Price the stipend at app or web rates, then compare keeping Premium, adding Plus or cancelling at your monthly Robux spend.
Does Roblox Plus out-earn its $4.99? Price the 10%/20% discount against your real monthly spending, plus a Plus Bundle checker.
What a gamepass or dev product price keeps after Roblox's 30% share: a price table, DevEx value per sale, the lowest price for a Robux goal, and 30-day revenue.
Calculator 2
Chance of a drop in N tries, tries for 50/90/99% odds, two or more drops, and how far a quoted drop rate can be trusted. You type the rate.
Compare both sides of a limiteds trade on our tracker's value estimates and RAP, with pending items excluded and a verdict.
Database 2
Classic Roblox limiteds ranked by our estimate, with RAP, units sold in 90 days and an activity read, from Roblox's own resale records. Keep a private watchlist on the same page.
Chart any tracked game's daily concurrent-player history from our own archive, banked daily since June 28, 2026, with missed days marked as gaps.
Utility 6
Paste an asset URL or ID to pull out the ID and open the route that actually resolves for it.
Estimate how much your Roblox account is worth from limiteds, Robux, age, and Premium.
See exactly how old your Roblox account is in days and years, with veteran milestones.
Find the user ID from a profile URL and open the official avatar view. No images embedded since September 2026.
Check Roblox value (account worth, limited RAP and item value) with a quick estimate.
Paste any Roblox game URL and get the place ID, a copy button and a clean link back to the game page. Pure parsing - nothing is fetched, no universe ID lookup.

About these Roblox tools
The Economy tools cover Roblox’s own money: converting Robux to USD, comparing Robux packs, what a limited resale or a game pass nets after Roblox’s fee, DevEx cashouts, group payouts, and whether Premium or Roblox Plus pays for itself. The Utility tools read an ID from a Roblox link and open the right page: asset IDs, avatars and game IDs, plus the account age and account value calculators. The Database pages are built from Roblox’s public data: the limiteds market and the player-count history.
Everything runs in your browser. No tool asks you to log in, and nothing you type is sent anywhere. Why none of the lookups searches Roblox by username or shows Roblox images is on how our tools work.
FAQ
Are these Roblox tools free?
Yes. Every tool on BloxToolbox is free to use with no account, sign-up, or download.
Do I need to log in with my Roblox account?
No, and you never should. No tool here asks for your Roblox login, and anything that does is a scam. The calculators work from numbers you type, and the avatar viewer works from a public profile URL.
Where do the numbers come from?
The calculators use Roblox’s published rates, and each one links the Roblox page they come from next to the date they were last checked. The limiteds market reads Roblox’s resale records for each item, and the player-count history keeps one reading a day per game since June 28, 2026, with missed days left as gaps.
How often is the data updated?
The limiteds market is read again on every site build, and each data page shows when its data was read. A calculator’s rates change when Roblox changes them; the date beside each tool says when they were last checked.
