About this tool
Different meats roast at different rates, and this calculator applies a typical minutes-per-kilogram rate for your chosen meat and doneness. Times are guides for a standard oven: always confirm with a meat thermometer, since shape and starting temperature change results.
Frequently asked questions
Does bone change the time?
Yes. Bone-in joints often need longer than boneless ones of the same weight, so check earlier and later around the estimate.
Should meat rest after roasting?
Yes. Resting lets juices settle and the temperature even out, which makes carving cleaner and the meat juicier.
