What does it cost to raise a lamb for meat?

Short answer

About $280 a lamb before the butcher — roughly $5.50 a pound of lamb in the freezer, or $8 if you have it boned

UNL's lamb-feeding example takes a 70-lb lamb to 140 lb in 90 days at 0.78 lb a day, eating 4.5 lb a day (3.55 lb of corn, 0.9 lb of alfalfa, 0.05 lb of supplement), for $100 of feed and $35 of other cost. NDSU's research flock valued a weaned lamb of about 73 lb at $150.59 (2020–22 mean) — about $145 scaled to 70 lb — so a finished lamb costs roughly $280. A 140-lb lamb hangs at 54%, about 76 lb, shrinks 3% in the cooler to 73 lb, and comes home as about 51 lb of bone-in cuts or 34 lb boneless (UW–Madison, K-State). That is about $5.46 a pound bone-in or $8.21 boneless before processing.

The arithmetic

The lamb: NDSU's research flock valued a ~73-lb weaned lamb at $150.59 (2020–22 mean) — about $145 at 70 lb. Your local price is the one that counts; if you raised it, this line is your ewe's share.
Feed = gain × feed cost per pound of gain. 140 − 70 = 70 lb of gain over 90 days at 0.78 lb a day (UNL). UNL's $100 of feed is $1.43 per pound of gain; 4.5 lb a day at 0.78 lb of gain is about 5.8 lb of feed per pound of gain (our arithmetic).
Other: UNL adds $35 a head, $0.50 per pound of gain. Total: $145 + $100 + $35 = $280.
Take-home: 140 lb × 54% = 76 lb hanging; 3% cooler shrink → 73 lb; × 70% bone-in = 51 lb, or × 46.5% boneless = 34 lb. $280 ÷ 51 = $5.46 a pound.

Why do the lamb-feeding budgets lose money when the freezer math says about $5 a pound?

Because they measure different things: the sale barn pays by the live pound, the freezer counts packaged pounds.

Live vs. hanging vs. packaged: The same $280 is $2.00 a pound of live lamb, $3.70 a pound hanging and $5.46 a pound of bone-in lamb in the freezer ($8.21 boneless)
NDSU's research flock: Over 2020–22 NDSU fed lambs from about 73 lb to 120 lb in 76 days at 0.61 lb a day. Feed and hay were $45.06; the lamb $150.59; total cost $220.66 against $201.75 of revenue — a loss of $18.91 a lamb
UNL's 60 months: In UNL's lamb-feeding margin series, net margins were negative in 35 of the 60 months from 2020 to 2024; the 2022 average was −$28.87 a head
Speed of gain: NDSU's lambs gained 0.43–0.87 lb a day depending on the year. On 70 lb of gain that is 163 days at the slow end and 81 at the fast end — the days carry the feed, the hay and the labor

Feedlots sell by the live pound and lose when feeders and feed cost more than the market pays. A freezer is worth what those cuts cost at the store, so the same lamb can lose money at the sale barn and still be worth raising for your own table — if your per-pound number beats the store's for the cuts you would actually buy.

Divide by packaged pounds, include the processor's whole bill, and compare to the store, not to the sale barn.

What changes your number

Price of the lamb. The biggest line — about half of the $280. A $35 swing on the lamb moves the bone-in price by about 68 cents a pound.
Feed price. At UNL's $1.43 per pound of gain, feed is 36% of the cost. At $1.00 per pound of gain bone-in lamb is $4.87 a pound; at $1.90 it is $6.10.
Daily gain. Slower lambs cost more days: 70 lb of gain is 90 days at 0.78 lb a day and 115 days at 0.61 lb a day. The extra days carry hay, labor and interest.
Dressing and the fleece. A lamb dresses at 54–59% (K-State), and 54% shorn against 52% unshorn (UW–Madison) — a lamb in full fleece brings home less for the same weight on the scale.
Bone-in or boneless. Boneless, closely trimmed cuts are 43–50% of the carcass against 65–75% bone-in (UW–Madison) — about 17 lb less meat from the same lamb.
Freezer space. A lamb is about 51 lb packaged — roughly 1.3–1.7 cubic feet at 30–40 lb per cubic foot (Kentucky). Two lambs fit in a corner of a chest freezer.

A number we won't give you

A processing price. Kill fees and cut-and-wrap charges vary by shop and region, and no extension service publishes a figure we would stand behind; the calculator starts processing at $0 so it can't pretend. Also missing: the cost of a lamb you raise on your own ewes. We found no extension budget that turns a ewe flock into a per-lamb number we would quote here, so the "price paid per lamb" field is where your own figure goes.

One lamb, 70 → 140 lb, before processing

Price of the 70-lb lamb	Total per lamb	Per lb, bone-in (~51 lb)	Per lb, boneless (~34 lb)
$110	$245	$4.77	$7.19
$145	$280	$5.46	$8.21
$180	$315	$6.14	$9.24

Feed at UNL's $1.43 per pound of gain and $35 of other cost. Packaged weights use 54% dressing, 3% cooler shrink, and 70% bone-in or 46.5% boneless of the carcass.

What feed price does to the number

Feed per lb of gain	Feed per lamb	Total per lamb	Per lb, bone-in	Per lb, boneless
$1.00	$70	$250	$4.87	$7.33
$1.43 (UNL's example)	$100	$280	$5.46	$8.21
$1.90	$133	$313	$6.10	$9.18

Lamb at $145 and $35 of other cost. Feed price here is dollars per pound of gain, so it already includes how much the lamb eats.

Time to market weight

Start → market	At 0.78 lb a day (UNL)	At 0.61 lb a day (NDSU)
70 → 140 lb	90 days	115 days
70 → 130 lb	77 days	99 days

0.78 lb a day is UNL's example; 0.61 is NDSU's 2020–22 mean.

Where the money goes

For a bought and finished lamb, the lamb is about half the cost ($145 of $280), feed about a third ($100) and everything else an eighth ($35). Processing comes on top, and a flat kill fee spread over only about 51 lb of meat is a big share — get the quote before you buy the lambs.

Then stop planning from averages

The calculator is the estimate. In Homestead Paradise you log the weigh-ins and the feed for each animal, and the processing record takes the hanging weight and the cut sheet, so you see your actual cost per pound when the boxes come home. 14-day free trial, no card.
