How do I use this calculator?
This calculator lets you estimate either the total cooking time from a known weight, or the equivalent weight from a known cooking time, using a 13-minute-per-pound rule of thumb (actual cooking time varies by food type, thickness/shape, oven temperature, and doneness/safety target).
Calculator Operations:
- Enter the weight of the meat in pounds to estimate the total cooking time (using 13 minutes per pound).
- Enter the total cooking time in minutes to estimate the weight of the meat (using 13 minutes per pound).
This calculator estimates cooking time only; add any prep time, oven preheating time, and resting time separately if you want a full schedule.
Choose what to solve for, enter the shown known value, then select Calculate. Reset clears the calculator.
Estimate cooking time at 13 minutes per pound from the weight of your meat, shown in minutes and hours, or change the rate to 15 or 30 minutes per pound.

13 Minutes Per Pound Formula
The following formula is used to estimate total cooking time based on the weight of the item (and can be rearranged to estimate weight from time):
Variables:
- TCT is the total cooking time (minutes)
- W is the weight of the item (pounds)
To calculate the total cooking time, multiply the weight of the item by 13 minutes per pound.
What is the 13 Minutes Per Pound Rule?
The 13 minutes per pound rule is a rough cooking-time estimate that suggests cooking an item for about 13 minutes for every pound it weighs. It is not a universal rule for any particular food, cooking method, or oven temperature. Always follow a trusted recipe and verify doneness/safety with a food thermometer (for example, poultry should reach 165°F / 74°C in the thickest part).
How to Calculate Total Cooking Time?
The following steps outline how to calculate the total cooking time using the 13 minutes per pound rule.
- First, determine the weight of the item (W) in pounds.
- Next, use the formula from above: TCT = W * 13.
- Finally, calculate the total cooking time (TCT) in minutes.
- After inserting the weight and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Weight of the item (W) = 5 pounds
Using the 13 minutes per pound rule, the total cooking time (TCT) would be calculated as follows:
TCT = 5 pounds * 13 minutes per pound = 65 minutes
