Surplus

Surplus carries two related meanings in preparedness. We use it first for the deliberate excess of essential resources you keep beyond immediate need. That covers food, water, fuel, medical supplies, cash, and even skills and community ties. It also names military surplus, the used or overstocked government gear sold to the public. That gear is built to hard-use standards and often sells at a fraction of retail.

Preppers meet the term because surplus is the margin that lets a household absorb a disruption. When a supply chain breaks or food shortages empty store shelves, you draw down a buffer instead of starting from zero. The same margin carries a family through an economic shock. The levels of economic collapse show how deep that buffer may need to run. Many families also grow their own surplus through homesteading, putting by what the garden produces right where they live.
