Start from what you keep
The marketplace takes roughly 30% of every sale, so a 100-Robux gamepass pays 70. Work backwards from the Robux you actually need per sale, then test price points: clean numbers (100, 250, 500, 999) both read better and survive fee rounding more predictably than odd amounts.
Match price to session value
Gamepasses selling best are permanent conveniences — 2× speed, extra inventory, VIP areas — priced near what a player earns or enjoys in one session. Watch comparable games with the same audience size; underpricing a beloved pass leaves Robux on the table, while overpricing kills the impulse-buy window.
Multiple passes beat one giant pass
Three passes at 99/199/399 (convenience, cosmetic, power) convert more total Robux than a single 500 bundle, because players self-select. Keep the top tier genuinely special — scarcity on the top shelf pulls the middle tier upward.
