This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own 99 Nights in the Forest π¦ session. It will not click the shop.
Material planner
Material shortfall
Enter one material's cost, how many crafts you want, and how much you already hold. The result is the shortfall for that material only.
Required total = materials per upgrade Γ number of upgrades. Missing = max(required total β materials already owned, 0).
Defaults match the Map recipe from the August 22, 2025 crafting table: 3 Wood for one Map. Replace the three numbers with any single material you are short on. The form does not read your sack, and it does not know drop rates.
