How does this calculator work?
For a whole bone-in turkey, allow 1.25 lbs per person for dinner only or 1.75 lbs per person for leftovers. Bone-in breast: 0.75 / 1 lbs per person. Boneless: 0.5 / 0.75 lbs per person. Multiply by guest count and round up to the nearest whole bird.
Formula
How this is calculated
The classic rule of thumb is to allow 1.25 pounds of whole bone-in turkey per guest for dinner only, or 1.75 pounds per person if you want a generous supply for leftovers. These figures account for the fact that roughly half the weight of a whole turkey is bone, cavity and fat — the edible meat yield is typically 40–55% of the purchased weight, so the per-person allowance looks higher than the actual portion size on the plate.
Bone-in turkey breasts are all white meat with fewer bones, so a smaller allowance (0.75 lbs/person for dinner, 1 lb with leftovers) is usually sufficient. Boneless roasts and rolled breasts have almost no bone loss, so 0.5 lbs/person covers dinner and 0.75 lbs adds a comfortable leftover margin.
At the store, whole turkeys are sold in fixed weight increments, so always round your calculated total up to the next available size. The optional price field multiplies total pounds by cost per pound for a rough budget estimate; actual prices vary by brand, grade and region.
Frequently asked questions
For a whole bone-in turkey with no leftovers, buy about 12–13 lbs (1.25 lbs × 10). For leftovers, aim for 17–18 lbs (1.75 lbs × 10). Round up to the next whole bird size available — running short is far worse than having extra.
Only 40–55% of a whole bone-in turkey's weight is edible meat — the rest is bone, carcass and fat. The per-person allowance is set for the total purchased weight, not just the meat on the plate, which is why 1.25 lbs per person yields a reasonable serving.
Always round up to the next available size. A bird 1–2 lbs heavier than calculated gives you a comfortable buffer. Leftover turkey freezes excellently for soups, sandwiches and casseroles for up to three months.
