This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Run a Restaurant! session. It will not click the shop.
Material planner
Ingredient shortfall
Enter how many ingredients one dish uses, how many dishes you want to cook, and how many you already hold. The result is how many you still need. Defaults are blanks for you to replace, not in-game drop rates.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Read the amounts off the recipe card. Pumpkin pie needing honey is a reason to run this before a long session, not a number this form knows for you.
Upgrade payback
Training payback
Estimate how many service cycles a staff upgrade needs to earn its cost back. You supply the training cost, the extra cash per cycle, and how many minutes a cycle takes. The game does not publish one official profit-per-level, so leave the defaults and type your own stove or rancher numbers.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
75,000 and 100 are placeholders so the form is not empty. Replace them. A farmer level-5 cost near 75k is only a reasonable starting guess if that is the upgrade you are pricing.
