Turkey Defrost Time Calculator
Enter your turkey weight and choose a thawing method. The calculator applies the USDA Food Safety and Inspection Service rates to give you the exact defrost time, plus a start-by time if you enter your planned cooking time. Both refrigerator and cold water methods are covered with safety tips for each.
How long does it take to defrost a turkey?
The USDA Food Safety and Inspection Service (FSIS) recommends two safe methods for thawing a frozen turkey: in the refrigerator or in cold water. In the refrigerator, plan for approximately 24 hours of thaw time for every 4 to 5 pounds of turkey. A 16-pound bird, for example, takes 3 to 4 days. The cold water method is roughly ten times faster: allow 30 minutes per pound, submerging the turkey in cold water and replacing the water every 30 minutes. A 16-pound turkey thaws in about 8 hours this way, but it must be cooked immediately after thawing.
Refrigerator vs. cold water thawing
Refrigerator thawing is the safest and most hands-off method. The turkey stays at a consistently safe temperature (below 40 F / 4 C) throughout, bacteria cannot multiply, and you can store the thawed turkey in the fridge for 1 to 2 more days before cooking. The only drawback is time: a large turkey can take 5 to 6 days. Cold water thawing is much faster but requires attention. You must keep the turkey fully submerged in its original wrapper or a leakproof bag, and replace the water every 30 minutes to prevent it from warming into the danger zone (40 to 140 F). Once thawed by the cold water method, cook the turkey immediately - do not refreeze it. Both methods are USDA-approved. Thawing at room temperature and in hot water are NOT safe.
Safety rules for thawing turkey
Never thaw a turkey on the kitchen counter at room temperature. The outer layers enter the bacterial danger zone (40 to 140 F) while the inside is still frozen, allowing harmful bacteria such as Salmonella to multiply rapidly. Similarly, avoid hot water thawing. Always keep turkey at 40 F or below during thawing. After cold water thawing, cook the bird right away. After refrigerator thawing, you have 1 to 2 days to cook. If you forget to thaw and are out of time, you can cook a frozen turkey directly - it will simply take about 50 percent longer than a thawed turkey.
What about microwave thawing?
Microwave thawing is approved by the USDA as a third safe option, but this calculator does not include it because thaw times vary greatly by microwave wattage and turkey size. If you use the microwave, follow your microwave manual, check frequently, and cook the turkey immediately after thawing since some parts may begin to cook during the process. A microwave is best reserved for very small turkeys or turkey pieces rather than a full 20-pound bird.
USDA turkey thawing times by weight
| Turkey weight | Refrigerator thaw | Cold water thaw | Size |
|---|---|---|---|
| 4-8 lb | 1-2 days | 2-4 hours | Small |
| 8-12 lb | 2-3 days | 4-6 hours | Small-medium |
| 12-16 lb | 3-4 days | 6-8 hours | Medium |
| 16-20 lb | 4-5 days | 8-10 hours | Large |
| 20-24 lb | 5-6 days | 10-12 hours | Extra large |
| 24-28 lb | 6-7 days | 12-14 hours | Jumbo |

Frequently asked questions
How long does it take to thaw a turkey in the refrigerator?
Allow 24 hours of refrigerator time for every 4 to 5 pounds of turkey. A 12-pound turkey takes about 3 days, a 16-pound turkey takes 3 to 4 days, and a 20-pound turkey takes 4 to 5 days. Keep the turkey on a tray on the lowest refrigerator shelf to catch any drip.
How long does the cold water method take?
Allow 30 minutes per pound of turkey. A 12-pound turkey takes about 6 hours, a 16-pound turkey takes 8 hours, and a 20-pound turkey takes 10 hours. Replace the cold water every 30 minutes and keep the turkey in its original wrapper or a sealed leakproof bag.
Can I thaw a turkey on the counter overnight?
No. Leaving a turkey at room temperature is unsafe. The outer layers quickly enter the danger zone (40 to 140 F) where bacteria multiply, even while the center is still frozen. Use the refrigerator or cold water method only.
How long can a thawed turkey stay in the refrigerator before cooking?
A turkey thawed in the refrigerator can remain there safely for 1 to 2 days before cooking. A turkey thawed by the cold water method must be cooked immediately - it cannot be held.
What if I forgot to thaw my turkey in time?
You can cook a turkey from frozen. It is safe, just plan for the cooking time to be roughly 50 percent longer than for a thawed turkey. Remove the giblets and neck as soon as the cavity thaws enough during cooking. Alternatively, switch to the cold water method if you still have enough time.
Can I refreeze a turkey after thawing?
You can safely refreeze a turkey that was thawed in the refrigerator, as long as it stayed at or below 40 F the entire time. A turkey thawed by the cold water method must not be refrozen - it must be cooked first.
