How Much Turkey Per Person Calculator

The formula

• Bone in whole turkey: (adults × 1.25 lb) + (children × 0.75 lb)
• Boneless turkey breast: (adults × 0.5 lb) + (children × 0.25 lb)
• Want leftovers? Multiply the base weight by 1.5
• Roast time at 325°F: weight × 13 minutes per pound (unstuffed), × 15.5 minutes per pound (stuffed)
• Refrigerator thaw: about 1 day per 4 to 5 lb of turkey

A worked example

8 adults and 4 children, whole bone in turkey, with leftovers: (8 × 1.25) + (4 × 0.75) = 13 lb; × 1.5 for leftovers = 19.5 lb, buy a 20 lb bird. Roast unstuffed at 325°F: 20 × 13 = 260 minutes, about 4 hours 20 minutes. Thaw it in the fridge 4 to 5 days ahead, and expect roughly 10 lb of cooked meat, about 20 generous servings.

The per person rule of thumb

Plan roughly 1.25 pounds of whole bone in turkey per adult and 0.75 pounds per child.

That sounds generous until you account for yield: only about 40 to 50 percent of a whole bird is edible meat, with the rest lost to bone, skin and cooking shrinkage.

Want leftovers for sandwiches and soup? Add 50 percent, roughly 1.9 pounds per adult instead.

Bone in whole turkey vs boneless breast

A whole bone in turkey gives the classic presentation and richer drippings for gravy, but you are paying for bone weight you will never eat.

Boneless turkey breast is nearly all meat, so you only need about 0.5 pounds per adult and 0.25 pounds per child, and it roasts faster, which suits smaller groups.

Choose a whole bird when you want drumsticks, wings and drippings; choose breast for simplicity, or when most guests prefer white meat.

Cook time and safe temperature

At 325°F an unstuffed turkey roasts in about 13 minutes per pound; a stuffed bird needs about 15.5 minutes per pound.

These are estimates, always confirm doneness with a probe thermometer in the thickest part of the thigh and the breast.

Turkey is safe to eat at 165°F internal temperature (USDA). Pull it a few degrees early and rest it 20 to 30 minutes before carving; carryover cooking finishes the job.

Thawing, and why two small birds beat one giant

Thaw in the fridge at roughly 1 day per 4 to 5 pounds, a 20 lb bird needs 4 to 5 days on a rimmed tray to catch drips.

In a hurry? The cold water method takes about 30 minutes per pound, with the water changed every 30 minutes, and the bird must be cooked immediately after.

Above about 20 to 22 pounds, consider two smaller turkeys instead of one giant bird: they thaw faster, cook more evenly and are easier to lift safely. Planning the sides for the same guest list? The Pasta Per Person Calculator in our /cooking-recipes/ kitchen collection sizes those too.

Turkey cook times: the quick reference

USDA guidance: roast at 325°F or above and cook to 165°F internal in the thickest part of the thigh. Time runs roughly 13 minutes per pound unstuffed, a 15 lb bird is about 3¼ hours; stuffed birds add roughly 15 to 20%.

Rest the bird 20 to 30 minutes before carving. Internal temperature keeps rising a few degrees (carryover), and the juices redistribute instead of flooding the cutting board.

A thermometer beats the pop up timer every time. Check the thigh, the wing joint and the stuffing centre; the breast dries out fastest, so shield it with foil if it browns early.

Planning the sides, gravy and carving yield around the bird

Work through a full table once. Suppose you are feeding 10 adults and 6 children a whole bone in turkey with no special plan for leftovers. The calculator budgets 10 × 1.25 = 12.5 pounds for the adults and 6 × 0.75 = 4.5 pounds for the children, giving 17 pounds in total, so you shop for an 18 pound bird, the closest common size above the number rather than below it.

That 18 pound purchase weight is not what lands on plates. A whole turkey yields roughly 40 to 50 percent edible meat once bone, skin and cooking shrinkage are accounted for, so expect around 8 pounds of cooked meat from a bird that size. Planning side dishes against the raw weight is a classic hosting mistake: the bird looks enormous in the cart, yet the carved meat is a far more modest pile than most first time hosts expect.

Use the cooked yield to sanity check the rest of the menu. If turkey is the only protein and your guests are big eaters, stay at the generous end of the range or add a second protein such as a ham, rather than jumping two bird sizes up. If the table already carries several hearty sides and desserts, the standard per person allowance is plenty, because the turkey is sharing the plate instead of filling it alone.

Whole bird or boneless breast: choosing for your table

Choose a whole bone in bird when the presentation matters, when guests expect a mix of white and dark meat, and when you want the carcass afterwards for stock. The cost per serving is usually helped by the fact that you are buying the entire bird, and the drumsticks and thighs give the meal variety that a plain breast cannot match. The trade off is oven time, carving effort and the thawing days a large frozen bird demands.

Choose boneless breast when the group is small, when everyone at the table prefers white meat, or when oven space is tight and timing is tight too. The calculator budgets about 0.5 pounds per adult and 0.25 pounds per child for breast, so 6 adults and 2 children need 6 × 0.5 + 2 × 0.25 = 3.5 pounds, or 5.25 pounds if you multiply by 1.5 to guarantee sandwich leftovers the next day.

Whichever you pick, respect the calendar the bird imposes. A frozen 17 to 18 pound turkey needs roughly four days of refrigerator thawing at the rate of about 24 hours per 4 to 5 pounds, and at roughly 13 minutes per pound at 325°F it needs close to four hours in the oven. Buying the right size on the wrong day still fails, so work backwards from the meal and shop with the thawing time already counted.

Leftovers on purpose: when to scale the bird up

Leftovers are a decision, not an accident, and the calculator treats them as a multiplier rather than a vague hope. Take the 6 adult, 2 child boneless breast example from earlier: the base need was 3.5 pounds, and multiplying by 1.5 lifted the purchase to 5.25 pounds, which is what guarantees next day sandwiches instead of a polite scraping of the serving plate. Apply the same thinking to a whole bird before you simply buy the next size up.

Scale up for the right reasons, though. A table of enthusiastic eaters, a long afternoon of grazing rather than one seated meal, or a household that genuinely cooks with leftover turkey all justify the bigger purchase. A vague fear of running short usually does not, because the sides, breads and desserts on a holiday table carry more of the meal than hosts admit, and an unnecessarily giant bird adds thawing days, oven hours and carving work along with its extra meat.
