Cold survival estimator

Set the conditions and your gear to estimate how long you could stay out in the cold before it turns dangerous. This is a fan-made model built on Permafrost's themes, not official game values, so treat it as a planning toy rather than exact numbers.

How to read this

In Permafrost, the cold is the central threat. Frostbite, storms and a creeping chill drain you constantly, and warmth is the resource everything else depends on. This estimator turns that idea into a simple what-if: colder temperatures, worse weather and thinner clothing shorten your safe window, while heavy layers and a nearby fire or shelter extend it. For the real mechanics, see cold & frostbite and cold-weather clothing.
