Toilet Paper still needed
Work out how much Toilet Paper is still missing for a known purchase. Use 150 for the published Spoon-to-Trowel path (25 + 45 + 80), 200 for the Illegal Keycard, 100 for the Crowbar, or 300 for the keycard and crowbar together. Sack prices are 20, 40, and 65. Dynamite is 12 each.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Leave Toilet Paper per unit at 1. The form subtracts what you already hold from a target you type. It does not read a save. Bargainer's 20 percent shop discount is not applied; type the discounted target yourself. In-game rounding of that discount was not published.
