How This Calculator Works

This calculator starts from the standard USDA/Butterball minutes-per-pound reference chart for a 325°F oven, with separate tiers for stuffed and unstuffed turkeys (stuffing slows heat reaching the center, so stuffed birds need more time). For convection, it applies a flat 25% time reduction, since fan-driven air circulation cooks faster at the same temperature. For spatchcocking, it switches to a much faster rate entirely — flattening the bird exposes far more surface area, so it roasts at a high temperature in a fraction of the time, and cannot be stuffed since there is no cavity. Any oven temperature above or below the method's standard baseline further adjusts the total time up or down.
