This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [π FALL SKINS] Tower Defense Simulator session. It will not click the shop.
Material planner
Coins still needed
Enter a tower's coin price, how many copies you are buying, and your current Coin balance. The form subtracts what you already have. The sample price is Farm at 2,000 Coins. Gem prices, Robux prices, and level gates are not part of this subtraction.
Required total = materials per upgrade Γ number of upgrades. Missing = max(required total β materials already owned, 0).
Farm is 2,000 Coins on the tower table. Replace the price for any other coin tower. This does not read your account.
