Turkey Cooking Time Calculator
This turkey cooking time calculator tells you exactly how long to cook your turkey based on weight, oven temperature, and whether it’s stuffed.
How This Turkey Cooking Time Calculator Works
This turkey cooking time calculator takes the guesswork out of one of the most stressful parts of the holidays: figuring out exactly when your turkey will be done. Calculating cooking time for turkey depends on three things: the weight of the bird, the oven temperature, and whether it’s stuffed. This calculator uses standard roasting guidelines to estimate total cook time, then adjusts that estimate based on your oven temperature and stuffing choice. A heavier turkey needs more time, a stuffed turkey needs more time than an unstuffed one at the same weight, and a hotter oven cooks the bird faster — but not in a perfectly linear way, since higher heat also increases the risk of the outside overcooking before the inside catches up.
This tool is built to give you a reliable starting estimate, not a guarantee down to the minute. Ovens vary, turkeys vary, and factors like whether the bird was fully thawed, how accurate your oven’s thermostat actually is, and whether you’re using a convection setting can all shift the real cook time by 15–30 minutes in either direction. That’s exactly why the calculator’s result should be treated as a planning number — a way to know roughly when to start checking — rather than a substitute for a meat thermometer.
Turkey Roasting Time Chart by Weight
For reference, here’s how standard roasting times break down at 325°F, the most commonly recommended oven temperature for whole turkeys:
| Turkey Weight | Unstuffed (325°F) | Stuffed (325°F) |
|---|---|---|
| 8–12 lbs | 2¾ – 3 hours | 3 – 3½ hours |
| 12–14 lbs | 3 – 3¾ hours | 3½ – 4 hours |
| 14–18 lbs | 3¾ – 4¼ hours | 4 – 4¼ hours |
| 18–20 lbs | 4¼ – 4½ hours | 4¼ – 4¾ hours |
| 20–24 lbs | 4½ – 5 hours | 4¾ – 5¼ hours |
Notice how the gap between stuffed and unstuffed narrows as the bird gets larger — a stuffed 10-pound turkey takes meaningfully longer relative to its unstuffed counterpart than a stuffed 22-pound turkey does. That’s because stuffing adds density at the center of the cavity, and in a large bird, that center was already the slowest part to heat regardless of stuffing.
How Oven Temperature Changes Cooking Time
Roasting at 325°F is the standard recommendation because it cooks the turkey evenly all the way through without drying out the exterior before the interior reaches a safe temperature. Raising the oven temperature does shorten total cook time, but the relationship isn’t perfectly proportional — a 400°F oven doesn’t cook a turkey in exactly 325/400ths of the time. Higher heat browns and can dry out the skin and outer meat faster than it fully cooks the interior, especially around the thighs and stuffing cavity, which is why most roasting charts still center on 325°F–350°F as the sweet spot between speed and even cooking.
Frequently Asked Questions
At 325°F, an unstuffed turkey takes roughly 13 minutes per pound, while a stuffed turkey takes closer to 15 minutes per pound. A typical 14-pound unstuffed turkey takes about 3¾ to 4 hours, while the same bird stuffed takes closer to 4 to 4¼ hours. Always verify with a meat thermometer rather than relying on time alone.
Yes. Stuffing adds density inside the cavity, which slows how quickly heat reaches the center of the bird. Both the turkey meat and the stuffing itself need to reach a safe internal temperature of 165°F. Cooking a home-stuffed turkey is riskier than cooking one unstuffed, and undercooked stuffing removed too early can be contaminated. Do not remove stuffing from the turkey until it has reached 165°F at its center.
325°F is the most commonly recommended temperature for whole turkeys because it cooks the bird evenly without over-browning the skin before the interior is fully done. Some cooks use 350°F for a slightly faster cook, while higher temperatures (400°F+) are typically reserved for spatchcocked or smaller birds.
Use a meat thermometer inserted into the innermost part of the thigh and wing, and the thickest part of the breast. All should read at least 165°F. If the turkey is stuffed, check the center of the stuffing as well — it must also reach 165°F. Cooking time estimates, including this calculator’s result, are a helpful guide for planning, but the thermometer reading is what actually confirms doneness.
