Turkey Calculator: Size, Thawing and Cooking Time

Size, thaw and roast time from the USDA tables, with a schedule that counts back from dinner.

This calculator turns the USDA Food Safety and Inspection Service guide Let's Talk Turkey into one plan. Enter the guests and it recommends a weight at the USDA rule of 1 pound per person, or 1½ pounds if you want leftovers. Enter the serving time and it finds the latest moment to start thawing in the refrigerator, falls back to cold water when the fridge is too slow, and shows the USDA rule for cooking from frozen when even that is too late. Then it counts back from the table roasting time and the 20-minute rest to tell you when to turn the oven on, when the turkey goes in and when it comes out. Everything runs in your browser, nothing is stored, and the roasting and thawing times are copied from the USDA tables rather than estimated from a formula.

Guests, bird, serving time: the plan appears by itself.

1. Set adults, children and whether you want leftovers. The recommended weight fills the bird weight, which you can overwrite with the real weight on the label.
2. Choose frozen or fresh, then the date and time you want to eat. The thaw card shows the latest start for each method and flags the ones that are already too late.
3. Pick stuffed or unstuffed and the oven. Add the reminders to your calendar, copy the plan, send it on WhatsApp or print it.
