International PayPal: $1 + 2%, capped at $21. US PayPal: $0.10 + 2%, capped at $1. FX fees may range from 1.9% to 3% and can change. The $35 wire fee is an example, not an official preset.

Model assumptions

Fee order and future earnings

This prototype models gross payout → transaction fee → FX fee. The exact fee basis and deduction order are not fully confirmed by official documentation, so you must opt in. Future monthly earnings are entered in USD; they are not assigned to balance categories or assumed to qualify for the US 18+ rate.

Not included

Taxes, eligibility and actual payment

All results exclude taxes. This tool does not determine Earned Robux eligibility, approval or arrival dates, and does not guarantee a full cashout after a balance refresh. You can simulate amounts below 30,000 R$, but that does not make them eligible for cashout.

Official recurring-split model

Per-game and group-wide revenue shares

Per-game shares are applied first. Group-wide shares apply to the remainder, and any unassigned balance stays in the group. Owners and members with the appropriate revenue permission can manage payouts. Recipient eligibility is determined by Roblox, not by this calculator.

Version and corrections

Prototype v0.8 · Based on PRD v3.2. Four languages: English, Brazilian Portuguese, Spanish and Indonesian. Shared calculations in every language. The 60,000 R$ example yields $232 gross. Includes gross USD goals, local estimate snapshots, summary export, fee comparison, recurring group splits and quick reference. No third-party analytics or automatic input sharing. Authorized revenue roles can also manage payouts.

Dollar values are in USD; R$ means Robux, not Brazilian reais. Numbers use 1,000.50 (comma for thousands, dot for decimals).
