A free tool built for Roblox creators — by someone who gets it.
DevExCalculator.us is a free, independent online tool that helps Roblox creators instantly convert their Robux earnings to real USD using the official Developer Exchange (DevEx) rate. We also provide an eligibility checker, fee estimator, monthly goal tracker, and PDF report download — all at no cost.
Most DevEx calculator sites online are basic single-function converters that only show the Robux-to-USD math. We wanted to build something that actually helps creators plan their income — not just calculate it. That means showing eligibility status, estimating PayPal fees, supporting global currencies, and letting creators set real monthly goals.
We take privacy seriously. Our tool runs entirely in your browser using JavaScript — no data you enter is ever sent to our servers or stored anywhere. Every calculation happens locally on your device.
The current official DevEx rate is $0.0035 per Robux (i.e., $3.50 per 1,000 Robux). This rate has been stable since 2017. We update this figure immediately if Roblox changes it. You can always see the "Last Updated" timestamp directly in our calculator.
DevExCalculator.us is an independent, fan-made resource. We are not affiliated with, endorsed by, or officially connected to Roblox Corporation. All figures shown are estimates for informational purposes only. Always verify your actual DevEx amounts in your official Roblox Creator Dashboard at create.roblox.com.
