Roblox Trading Calculator
Three tools in one: what your account is really worth, whether a trade is fair, and exactly what to list an item for— after Roblox's cut.
Look up your limiteds' current RAP (e.g. on Rolimons) and add them up, or enter the total — this tool does the real-money maths on top.
💡 RAP is an average, not a guaranteed sale price — a real sale can go for more or less. Limiteds also can't be DevEx'd directly; you'd need to sell them for Robux first.
FAQ
Why doesn't this tool show live RAP values?
RAP moves daily and a snapshot baked into a webpage goes stale fast — showing you an outdated number would be worse than not showing one. Look your item's current RAP up on a live tracker like Rolimons, then use this tool for the maths on top: real-money conversion, trade fairness and sale profit, none of which those trackers always spell out.
What percentage does Roblox take from Marketplace sales?
30% — you only ever net 70% of your listing price when you sell a limited on the Marketplace. This tool's Sale Profit tab does that maths both ways: what to list at to net a target amount, and what a given listing price actually pays you.
What counts as a fair Roblox trade?
There's no official rule, but the common community standard is roughly a 10% band either way — if both sides' total value (items' RAP + any Robux added) are within about 10% of each other, it's generally considered fair.
Can I turn limiteds straight into real money?
No — only Robux from your actual balance can be converted via DevEx (and only once you're an eligible, Premium creator with 30,000+ earned Robux). Limiteds have to be sold for Robux on the Marketplace first, and RAP is an average, not a guaranteed sale price.
