Permafrost Calculators & Planner
Plan a cold-weather trip, turn supplies into crafting batches, and compare food and fuel efficiency.
Your numbers, transparent math. Defaults are illustrative planning inputs, not verified game rates, recipes, unlock prices or survival thresholds. Replace them with values observed in your game version. Calculations stay in your browser.

How the calculation works
Food and water = days × survivors × daily rate × reserve multiplier, rounded up. Fuel = days × heating hours × baseline burn × (1 + colder degrees × sensitivity) × insulation reduction × reserve. Fuel is shared by the shelter; food and water are per survivor. Crafting batches cover the fuel inventory deficit. Clothing material costs use your entered sets and recipe. Temperature scaling is a user-calibrated model, not the game’s thermal simulation.
