How is roasting time estimated?

Using a time-per-pound guideline based on meat type, cut, and oven temperature.

Why confirm doneness with a thermometer?

Roasting time varies with oven accuracy and cut shape, so internal temperature is a more reliable check.

Does resting time matter?

Yes — it lets juices redistribute, improving texture, usually recommended in addition to cooking time.

Meat Roasting Calculator

Estimate roasting time and safe internal temperature for common meats in a 325°F oven.

What Is the Meat Roasting Calculator?

This calculator estimates roasting time and safe internal temperature for common meats, based on weight and your desired doneness, assuming a standard 325°F oven.

Formula

Roasting Time (minutes) = Minutes per Pound (based on meat type and doneness) × Weight (lb). Internal temperature targets follow common food-safety and doneness guidelines.

How to Use This Calculator

Select the type of meat you're roasting.
Enter its weight in pounds.
Select your desired doneness (poultry is always calculated to well done for food safety).
Click Calculate for the estimated time and target internal temperature.

Worked Example

A 5 lb beef roast cooked to medium at 20 minutes per pound needs about 1 hour 40 minutes in the oven, with a target internal temperature of 145°F.

Tips

Always confirm doneness with a meat thermometer rather than time alone — oven calibration, starting temperature, and cut shape all affect actual cooking time. Let roasts rest 10–15 minutes before carving.
