About

This calculator is made by plusbeauxjours, a small studio that builds free tools answering one question clearly, with sources.

It turns guidance from Ready.gov, the CDC and the American Red Cross into a shopping list for your household. We quote those pages word for word on Sources & method and print no number they don't give.
