Enter your pig's live weight and breed to get hanging weight, final cut yield, estimated pork cuts breakdown, freezer space needed, and butcher cost range. Includes an optional feed cost check.
Dressing percentage — also called dressing yield or kill yield — is the ratio of hanging weight (carcass weight after slaughter) to live weight, expressed as a percent. It represents how much of the animal's body weight ends up as usable carcass after you remove the blood, head, hide, and internal organs. For pigs, this number runs significantly higher than for beef cattle or deer because pigs have a relatively small digestive tract as a share of body weight, and their thick layer of subcutaneous fat is included in the hanging weight rather than discarded on the kill floor.
A commercial cross pig — Yorkshire, Duroc, or the industry-standard Yorkshire x Landrace x Duroc terminal cross — typically hits 72–76% dressing, with 74% as a reliable average. These breeds were developed specifically to maximize lean meat yield per pound of feed consumed, and their body composition reflects that. A 250-lb commercial pig will typically hang at around 185 lbs.
Heritage breeds like Berkshire, Red Wattle, Tamworth, and Gloucestershire Old Spot run closer to 68–72%, averaging around 70%. They carry more bone and organ weight relative to body size compared to modern commercial hogs, and their carcasses often have thicker back fat which, while delicious, adds to carcass weight but not to lean cut yield. Berkshire is popular with pastured pork producers because its meat has exceptional intramuscular fat (marbling) and pH stability post-slaughter, producing the prized dark, moist, deeply flavored pork that commands premium prices at farmers markets.
Mangalitsa and other lard-type breeds sit in the middle on dressing percentage — around 72% — but have dramatically higher fat content in the carcass. Their final lean cut yield is lower than a commercial pig, but the lard yield is substantially higher. Mangalitsa lard is prized by chefs and traditional cooks for its flavor and high smoke point.
The drop from hanging weight to final cut weight — also called "take-home weight" or "packaged weight" — surprises most first-time hog buyers. You pay the butcher's processing fee based on hanging weight, but the meat you bring home weighs considerably less. The difference goes to bone, additional fat trim, skin (if removed rather than cured as crackling), moisture loss during chilling, and any off-cuts you choose not to keep. The standard assumption in the industry is that final cut yield is 70–75% of hanging weight for a standard cut-and-wrap order.
If you keep everything — bones for broth, leaf lard, back fat for rendering, head for headcheese, trotters, and jowl — your take-home weight climbs significantly above the 70–75% figure. If you ask for extra fat trim on the chops and heavy defatting on the shoulder, it drops. This calculator uses 72% of hanging weight as the default for a standard order, which is accurate for most small-scale USDA-inspected processors in the U.S. Your specific processor's cutting style matters more than any calculator estimate — ask them what their typical take-home percentage runs before you plan your freezer space.
For whole hog processing (roasting pig or whole carcass sale), hanging weight and take-home weight are essentially the same thing — you're getting the whole carcass with minimal additional loss. For half hog orders, you typically split the carcass down the backbone and take two sides, with the same 70–75% cut yield on each half.
Feed conversion efficiency — the pounds of feed required per pound of weight gain — peaks in pigs between roughly 50 and 200 lbs live weight. In this range, pigs convert feed to body weight at a ratio of around 3:1 to 3.5:1. Below 50 lbs, the pig is still developing its skeletal and organ systems, so feed efficiency is poor. Above 200–220 lbs, feed conversion worsens as the pig deposits more energy as fat rather than lean tissue. A pig at 300 lbs is converting at 4:1 or worse — more feed per pound of gain, and much of that gain is fat rather than marketable lean pork.
The commercial industry targets 270–300 lbs live weight at slaughter, reached in about 5–6 months on a confinement diet. This seems to contradict the efficiency argument above, but commercial operations optimize for total throughput and muscle yield, not feed conversion alone. For small-scale homestead operations where feed cost is the primary expense, 220–250 lbs is typically the most economical slaughter window. A 250-lb pig at 74% dressing gives you 185 lbs hanging weight and roughly 133 lbs of cut meat — enough to fill a 4-cubic-foot chest freezer and provide about 6 months of pork for a family of four at moderate consumption.
If you want maximum bacon and lard, running the pig to 280–300 lbs makes sense for the right breeds (Berkshire, Mangalitsa), because back fat development accelerates in the final weeks. If you want the leanest possible chops and hams, 220–240 lbs on a commercial cross is the target.
The standard planning figure is 35–40 lbs of cut, packaged pork per cubic foot of freezer space. This accounts for the irregular shapes of vacuum-sealed packages, air gaps between packages, and typical packaging density from a commercial butcher. A 250-lb pig at standard yield produces around 130–135 lbs of cut meat, requiring roughly 3.5–4 cubic feet of dedicated freezer space. A standard 7-cubic-foot chest freezer is plenty for a whole pig with room to spare for other things.
If you're ordering a whole hog, plan 4–5 cubic feet. If you're splitting a hog with another family, 2–2.5 cubic feet per half is adequate. Keep in mind that if you also keep bones, lard, and organ meats, your volume increases by 15–20% over the packaged meat weight alone. Bones are bulky relative to their weight.
USDA-inspected small-scale pork processing typically runs $0.65–$0.90 per pound of hanging weight, though rates vary significantly by region and processor. The Midwest generally has the lowest rates; the Pacific Northwest and Northeast run higher. Specialty cuts (bone-in hams instead of fresh hams, custom sausage blends, cured bacon rather than fresh belly) add per-piece or per-pound charges on top of the base processing rate. Some processors also charge a kill fee of $50–$75 per head on top of the per-pound rate.
For a 250-lb pig at 74% dressing (185 lbs hanging weight), expect to pay $120–$165 in base processing fees, plus additional charges for specialty cuts. Get an itemized quote from your processor before the pig goes in — surprises on the invoice are common when buyers don't ask about kill fees, cure charges, and per-cut fees upfront.
Hanging weight is the carcass after bleed-out, scalding and scraping (or skinning), head removal, and evisceration — meaning all internal organs have been removed. The skin, back fat, leaf lard (internal fat pad around the kidneys), and kidneys may or may not be included depending on how your processor handles the carcass. In most U.S. small processors, the hide is left on and scalded/scraped rather than removed, so all the skin and subcutaneous fat is included in hanging weight. This is why pigs dress out at a higher percentage than beef — cattle are always skinned, which removes substantial weight, while pork carcasses retain the skin and fat cap. Organ meats (liver, heart, kidneys) are typically kept separate and returned to you on request; they are not included in the hanging weight calculation.
Commercial pork processing typically happens within 24 hours of slaughter — pork is not typically aged the way beef is, because it does not benefit the same way from long hanging times and presents more food safety considerations as the carcass ages. That said, 24–48 hours of chilling at 34–38°F before cutting allows rigor mortis to resolve and the meat to relax, which improves tenderness and cutting quality. Some specialty processors hang Berkshire and heritage breed carcasses for 48–72 hours to improve flavor. Very long aging (7+ days) is not practiced in pork processing and is not recommended for food safety reasons at most facilities. Your processor will handle this timing — just confirm they chill the carcass before cutting, which all licensed facilities are required to do.
If the meat is for your own household consumption only — not for sale, trade, or gifting to anyone outside your immediate household — you can legally process pigs on your farm in most U.S. states without USDA inspection. This is called "custom exempt" or "personal use" processing. If you want to sell the pork, give it as part of a CSA share, or donate it, a USDA-inspected facility is required. Many small processors hold both USDA inspection for commercial work and custom-exempt status for farm customers. Ask your processor before scheduling — if you plan to sell any portion of the pig or split a hog with a neighbor for compensation, you need USDA inspection on the kill.
Average U.S. pork consumption runs about 50 lbs per person per year, meaning a family of four would consume around 200 lbs of pork annually. One 250-lb commercial pig at standard yield produces roughly 130–135 lbs of cut meat — about eight months of supply for a family of four at average consumption, or a full year at moderate use with supplemental beef, chicken, and venison. If pork is your primary protein source, two pigs per year is a more comfortable supply. A single pig provides enough pork that many homestead families supplement with purchased pork in the off-season or raise two pigs and trade or sell one to offset costs. See our pig feed calculator to plan your feed budget before committing to a second pig.
For a standard cut-and-wrap order on a 250-lb pig, a typical cut sheet would include: 2 fresh hams or 1 smoked ham and 1 fresh; bone-in or boneless pork chops (3/4–1 inch thick from the loin); bone-in or boneless shoulder/Boston butt roasts; spare ribs or baby back ribs; fresh side (belly for bacon, either cured by you or smoked at the processor); ground pork or breakfast sausage bulk packs; and hocks and feet if you want them. Specify whether you want the leaf lard and caul fat returned to you for rendering — many processors discard these if not asked. The backbone makes excellent broth and is often available as a byproduct on request. Most processors provide a standard cut sheet with options to check off — mark everything you want explicitly, because unchecked items are typically discarded.
