How Roast Cooking Time Calculator Works
The calculation uses the formula:
Where:
- Weight = Weight of the roast in pounds
- Time Per Pound = Minutes per pound based on meat type and doneness
- Preparation Time = Additional time for browning, resting, and temperature adjustments
Key Concepts Explained
Meat Types
Different meats require different cooking times. Beef cooks faster than pork, and poultry requires the lowest temperatures.
Doneness Levels
Rare requires the shortest time, while well-done needs the longest. Temperature targets vary by doneness level.

Factors That Affect Your Results
1. Meat Type
Different meats have different densities and fat content, requiring different cooking times per pound for optimal results.
2. Starting Temperature
Room temperature meat cooks faster and more evenly than refrigerator-cold meat, which may require additional time.
3. Oven Calibration
Ovens that run hot or cold will affect actual cooking times, so using an oven thermometer is recommended for accuracy.
Frequently Asked Questions (FAQ)
Q: How do I calculate roast cooking time?
A: Roast cooking time is calculated based on the weight of the meat and the desired doneness. Different meats have different cooking times per pound, and the internal temperature varies by doneness level.
Q: What temperature should I cook a roast at?
A: Most roasts are cooked at 325°F to 350°F (165°C to 175°C). This temperature range allows for even cooking without drying out the meat.
Q: How do I know when my roast is done?
A: The most accurate way is to use a meat thermometer to check the internal temperature. Clear juices when pierced also indicate doneness.
Q: Should I cover my roast while cooking?
A: Generally, roasts are cooked uncovered to allow browning. If browning too quickly, tent loosely with foil. Pot roasts are typically covered.
Q: How long should I let my roast rest?
A: Rest for 10-20 minutes depending on size. This allows juices to redistribute, resulting in a more tender and flavorful roast.
Q: Can I use this calculator for slow cooking?
A: This calculator is designed for conventional oven roasting. Slow cooker times are significantly longer and require different calculations.
