About this calculator

This beef cooking time calculator helps you prepare oven roasts with precision. Simply enter the weight of the meat and the desired doneness (rare, medium, or well done). The tool automatically calculates the required time at 180 °C, following traditional ratios: 20 minutes per 500 grams for rare, 25 minutes for medium, and 30 minutes for well done. The result is displayed in hours and minutes, making meal planning easy.

The formula is straightforward: for every 500 grams of meat, multiply by the factor corresponding to the desired doneness. For example, a 1.5 kg piece for medium: (1500 / 500) × 25 = 75 minutes (1h15). The calculator supports weights up to 10 kg and rounds to the nearest whole minute. Important: the time is for a preheated oven at 180 °C and meat at room temperature before roasting. Always use a meat thermometer to check internal temperature: 52 °C for rare, 63 °C for medium, and 71 °C for well done.

When to use this calculator? Ideal for roasts like brisket, top round, rump, tenderloin, or eye of round. Useful for special dinners or everyday meals, ensuring the meat is neither undercooked nor overly dry. Remember that time may vary with the shape of the cut (thicker or thinner) and your oven's efficiency. Let the meat rest for 10 minutes after cooking to redistribute juices, resulting in a more succulent texture.

Important precautions: avoid opening the oven frequently, as heat loss alters cooking. If the meat is cold, add 10-15 minutes to the total time. For very large pieces (over 3 kg), consider using a roasting rack to circulate hot air. This tool is a practical guide, but experience and a thermometer are your best allies. Enjoy your perfectly cooked roast!

Frequently asked questions

Is the calculated time for conventional or electric ovens?

The calculator assumes a conventional oven at 180 °C. For electric ovens, the time may be similar, but we recommend checking internal temperature with a thermometer.

Can I use this calculator for pot roast or barbecue?

No. This calculator is specifically for oven roasts. Pot roast and barbecue require different times and temperatures.

What if my meat piece has an irregular shape?

The time is estimated for medium thickness. Very thick pieces may need more time; use a thermometer to ensure doneness.

Do I need to preheat the oven?

Yes. The calculation assumes a preheated oven at 180 °C. Placing meat in a cold oven increases cooking time.

Does the result include resting time?

No. The calculated time is only for cooking. We recommend resting the meat for 10 minutes after removing from the oven.
