Roasting time depends heavily on the type of meat and its weight, and knowing the safe minimum internal temperature is what actually determines doneness — not the clock alone. This calculator estimates roasting time by weight for common meats, alongside the USDA safe minimum internal temperature for each.
How it works
Select the meat type and enter its weight. The calculator applies a standard minutes-per-pound roasting rate for that meat and reports the estimated time along with its safe minimum internal temperature.
- Enter meat type.
- Enter weight (lbs).
- Click Calculate to see your results.
Examples
A 5 lb whole chicken
At 20 minutes per pound, a 5 lb whole chicken takes about 1 hour 40 minutes at 350°F, and should reach a safe internal temperature of 165°F.
Who should use it
- Planning roughly how long to roast a specific cut and weight of meat.
- Checking the correct safe internal temperature target for a specific meat type.
Industry applications
- Home cooking and meal planning
- Food safety education
Advantages
- Covers the most common meat types with their own specific rates and safe temperatures.
- Reports both estimated cooking time and the safe minimum internal temperature together.
Limitations
- Estimated time is a general guideline, not a guarantee — always confirm with a meat thermometer.
Common mistakes to avoid
- Relying only on estimated cooking time without confirming with a meat thermometer, which is the only reliable way to verify safe doneness.
- Using a red-meat cooking time estimate for poultry, which has a different required internal temperature and often a different roasting rate.
Best practices
- Always verify doneness with a meat thermometer inserted into the thickest part of the meat, away from bone, rather than relying on time alone.
Tips
- Let roasted meat rest for 10-15 minutes after reaching its safe temperature — this allows carryover cooking and juices to redistribute for a better result.
