Lamb Yield Calculator
Estimate how much lamb you'll take home from a live lamb. After the processor removes the bone, head, and organs, the leg, chops, rack, and shoulder cuts that remain typically run about 55% of the animal's live weight.
Type in the animal's live weight and the amounts the processor removes — Bones, Organs, Head — auto-fill at typical shares for a lamb. Adjust any of them for a closer estimate and the take-home weight updates as you type.

Estimates only — actual yield depends on cut style, fat and trim, moisture loss while aging, and what you ask the processor to keep. Confirm the expected weight with your processor before you send an animal.
What affects how much meat you take home
- Cut style. Boneless cuts mean more trimmed-out bone and less take-home weight; bone-in roasts and steaks weigh more.
- Trim and fat. A tight trim — or grinding the fat into burger — keeps more weight than cutting it all away.
- Shrink. Meat loses moisture while hanging and aging, which lowers the final weight.
- What you keep. Some people take the liver, heart, and other organs home instead of leaving them with the processor.

Lamb yield questions
How much meat will I get from a lamb?
A 120 lb lamb with the defaults here — live weight minus 20% bone, 16% organs, and 9% head — estimates to about 66 lb of take-home lamb. Whether cuts are boned or left bone-in changes the final number.
Why is lamb's take-home share lower than pork's?
Lamb carcasses carry a smaller share of meat relative to bone, and the default numbers subtract that bone, so the take-home share lands around 55% of live weight.
Do I get the liver and other organs?
Some processors return the liver, heart, and other organs if you ask. If you keep them, lower the organs line in the calculator so those pounds count toward your take-home weight.
Where can I get a lamb processed?
Search the directory for USDA-inspected lamb processors near you and ask about their cut sheet and expected yield before you book.
