How to use the turkey calculator

  1. 1
    Enter your guest count

    Count everyone eating, including kids (count small children as half a guest if you like). Pick the appetite that fits your crowd — hearty if your family fights over leftovers.

  2. 2
    Choose frozen or fresh

    Frozen birds are cheaper and easier to find, but need days of fridge thawing. Fresh birds skip the thaw entirely — just buy one Tuesday or Wednesday before Thanksgiving.

  3. 3
    Read your plan

    You get the recommended bird weight, thaw time, the exact date to start thawing for Nov 26, 2026, the 325°F cook-time range, what time the turkey goes in the oven, and the estimated cost.

  4. 4
    Trust the thermometer

    Cook times are estimates. The turkey is done when a meat thermometer reads 165°F in the thickest part of the thigh and the stuffing (if any), then rest it 20–30 minutes.

Why this calculator works

🦃 USDA-based sizing

The classic rule — 1 lb per person for average appetites, 1½ lb for hearty eaters who want leftovers, ¾ lb for lighter crowds — accounts for bone weight, which is why a “10 lb turkey” serves about 10.

❄️ Real thaw math

The USDA’s fridge rule is 24 hours of thawing per 4 lb of turkey; the cold-water shortcut is 30 minutes per pound with water changes every 30 minutes. We convert your bird’s weight into both, plus the calendar date to start.

🔥 Cook times at 325°F

Times use the standard 325°F roasting chart for unstuffed and stuffed birds, then we back up from your dinner time — including a 30-minute rest — to tell you when the turkey goes in the oven.

💰 Budget built in

Enter the price per pound from your store’s weekly ad and the calculator estimates the total bird cost, so the Thanksgiving budget has no surprises.

🪵 Leftovers logic

Hearty portions automatically build in extra meat for next-day sandwiches. We also remind you of the food-safety rule: refrigerate leftovers within 2 hours and eat them within 3–4 days.

📅 Dated for 2026

Thaw-start dates are computed for Thanksgiving 2026 (Thursday, Nov 26), so “start thawing Monday, Nov 23” is a real calendar date, not a vague “3 days before.”

Thanksgiving turkey FAQs

How much turkey do I need per person?
Plan on 1 lb per person for average appetites, 1½ lb per person for hearty eaters (this builds in leftovers), and about ¾ lb per person for a light crowd with lots of sides. The weight includes bones — a 10 lb turkey yields roughly 5–6 lb of cooked meat.
How long does it take to thaw a turkey in the fridge?
Allow 24 hours for every 4 lb of turkey. A 10 lb bird needs about 2½ days; a 20 lb bird needs 5 full days. Thaw breast-side up on a tray on the bottom shelf so drips can’t contaminate other food.
What’s the fastest safe way to thaw a turkey?
Submerge the wrapped bird in cold tap water, changing the water every 30 minutes — allow about 30 minutes per pound (a 10 lb turkey takes 5 hours). Cook it immediately after thawing. Never thaw a turkey at room temperature.
Can I cook a turkey from frozen?
Yes — the USDA says it’s safe, but it takes about 50% longer than a thawed bird, and you can’t safely stuff it. Thawing first gives better seasoning, more even cooking, and room for stuffing, so only roast from frozen as a backup plan.
What temperature should I roast at, and when is it done?
Roast at 325°F. The turkey is done when a meat thermometer reads 165°F in the thickest part of the thigh, the wing joint, and the center of the stuffing. Start checking about 30 minutes before the low end of the time range, then rest the bird 20–30 minutes before carving.
When should I start thawing for Thanksgiving 2026?
Thanksgiving is Thursday, Nov 26, 2026. Move the frozen bird to the fridge the number of thaw days before Thanksgiving — for example, a 10 lb turkey (2½ days) should start thawing on Monday, Nov 23. The calculator above computes your exact date automatically.
Should I stuff my turkey or cook the stuffing separately?
For food safety, the USDA recommends baking stuffing in a separate dish. If you do stuff the bird, pack it loosely, add roughly 30 minutes to the roast time, and verify the center of the stuffing hits 165°F — an undercooked center is the main risk.
How long do Thanksgiving leftovers keep?
Refrigerate all leftovers within 2 hours of serving, carve the meat off the bone before storing, and eat refrigerated turkey within 3–4 days. Reheat leftovers to 165°F. Freeze what you won’t eat in time — frozen turkey keeps 2–6 months.
