Rp still needed for a listed bike
Estimate how much in-game Rp is still short of one listed bicycle price. Enter the dealer price as the per-unit amount, set the count to 1, and enter the Rp you already have. The example default uses the Polygon Dealer listing of 2,500,000 Rp for POLYGON ROGUE and an example balance of 1,300,000 Rp, which leaves 1,200,000 Rp when the shortfall is the price minus the balance and cannot go below zero. This does not read a Roblox account. Do not reuse the POLYGON ROGUE price for PolygonRogueAnomali, and do not mix Robux game-pass prices into the Rp fields.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Shortfall uses the installed material calculator: per-unit amount times count, minus what you already have, and not below zero. Recalculate after you are paid. If a reward is already inside your balance, do not subtract it again.
