Built and checked against USDA guidance

The rates behind this calculator were built and tested by the Turkey Size Calculator kitchen team, then checked against USDA food-safety guidance for thawing and cooking. We keep the formula visible on purpose.

We built this tool because most turkey-size advice online is a single flat number that ignores your cut, your sides, and whether you actually want leftovers. Our goal is a calculator that respects how real tables eat.
