About Box ROI

Return on investment for Keycap Boxes measures whether spending on a higher tier produces enough income improvement to justify the wait. This calculator compares opening multiple cheap boxes versus saving for fewer expensive boxes based on average rarity value assumptions you enter.

Use alongside in-game Shop odds for accurate tier-specific decisions. Adjust average keycap value fields to match the rarities you typically pull from each tier.

How to Use

Enter your current cash, the cost and expected average keycap value for a cheap box tier, and the same for a premium tier. The calculator shows how many cheap openings your cash affords versus premium openings, and estimated total income improvement from each strategy.

When premium average value significantly exceeds cheap value multiplied by opening count ratio, saving wins. When plot slots are empty, cheap volume often wins regardless — fill slots first.
