  • Raw pork butt loses about half its weight as it cooks, so you need roughly twice the finished weight in raw pork — here, 8 lbs raw for 4 lbs cooked.
  • Cook pulled pork low and slow — about 1.5 hours per pound at 225°F — to a finished internal temperature of around 203°F, when the collagen has rendered and the meat shreds easily.
  • The cook-time estimate assumes a single piece of that weight. For a big crowd, cook two or three smaller butts in parallel — they finish much faster than one giant one.
  • Smoking time is unpredictable thanks to the stall. Start early, and hold finished pork wrapped in a dry cooler if it is done ahead of time.
  • Once the pork is pulled, keep it hot — above 140°F — for serving. The USDA warns against letting cooked meat sit in the danger zone between 40°F and 140°F.
  • Round up rather than down — leftover pulled pork freezes well, and running out at a cookout does not.

How to use this calculator

  1. Enter your guest count

    Type how many adults and how many kids you are feeding.

  2. Choose the serving size

    Pick light (sandwich-size), standard (a normal dinner portion), or hearty (heavy eaters).

  3. Read how much pork to buy

    The calculator shows the raw pork butt to buy, the cooked pulled pork it yields, and a rough smoking time.

  4. Cook low and slow to 203°F

    Smoke or roast the pork to a finished internal temperature of around 203°F, then rest and pull it.

Raw pork butt yields about 50% of its weight as finished pulled pork — buy roughly twice the cooked weight you need.

Tips & best practices

  • Round up, not down — leftover pulled pork freezes beautifully, and running short at a cookout is the worse outcome.
  • Cook multiple smaller butts instead of one huge one: they finish faster and give you more bark per pound.
  • Cook to temperature, not time — pull the pork at around 203°F internal, checked with a thermometer.
  • Build in a buffer. The stall makes smoking times unpredictable, so plan to finish early and hold the pork wrapped in a cooler.
  • Save the juices from the wrap or pan and toss them back into the pulled meat — it is the best way to keep it moist.
  • Keep finished pork above 140°F for serving, and refrigerate leftovers promptly to stay out of the bacteria danger zone.

Frequently asked questions

How much pulled pork do I need per person?
Plan on about 1/3 pound of cooked pulled pork per adult for a standard dinner portion, 1/4 pound for a lighter sandwich-size serving, and 1/2 pound for heavy eaters. Children eat roughly half an adult portion, about 1/6 pound.
How much raw pork butt should I buy?
Buy about twice the finished weight you need. A raw pork butt loses roughly 50% of its weight during a low-and-slow cook to rendered fat, evaporated moisture, and discarded bone — so 10 pounds of raw pork yields about 5 pounds of pulled pork.
Why does pork butt lose so much weight when cooked?
Pork shoulder is a fatty, collagen-rich cut. During the long cook, the fat renders out, a lot of moisture evaporates, and the bone and any large pieces of connective tissue are discarded when you pull it. A 50% yield is the standard planning figure.
How long does it take to smoke pulled pork?
Plan on roughly 1.5 hours per pound at 225°F. An 8-pound butt can take 12 hours or more. Cooking is done by temperature, not the clock — pull the pork when it reaches an internal temperature of around 203°F.
What internal temperature should pulled pork reach?
Cook pulled pork to a finished internal temperature of about 203°F. While the USDA-safe minimum for pork is 145°F, pulled pork is taken far higher so the collagen fully breaks down and the meat shreds apart easily.
Should I cook one big pork butt or several smaller ones?
For a crowd, cook two or three smaller butts in parallel rather than one giant one. They fit better on the smoker, cook noticeably faster, and give you more bark — the flavorful crust — per pound.
How do I keep pulled pork warm and safe for serving?
Keep cooked pulled pork above 140°F until it is served. The USDA identifies the range between 40°F and 140°F as the danger zone where bacteria multiply quickly. A wrapped cooler, a low oven, or a chafing dish all hold it safely.
Can I make pulled pork ahead of time?
Yes. Pulled pork reheats and freezes very well. Cook it ahead, cool it quickly, refrigerate or freeze it, and reheat it gently with a splash of liquid or saved cooking juices to keep it moist. This is also a good hedge against an unpredictable smoke time.
