Pulled Pork Cook Time Calculator: When to Put It On | BBQ Geek

Enter your pork butt weight, smoker temp and what time you want to eat, and this calculator tells you when to put the meat on and when to light the smoker. It uses the same approach as our brisket calculator but with numbers tuned for pork shoulder. Figure about an hour a pound at 250°F if you wrap, a bit longer if you don’t.

 

 

 

At 250°F with a foil wrap once the bark is set, a bone-in butt takes roughly 1 hour per pound, plus an hour of rest. Unwrapped it runs closer to 1 hour 10 minutes per pound. At 225°F unwrapped you’re looking at about 1 hour 15 minutes per pound, so a 9 pounder is an 11 hour cook. Bigger butts don’t take proportionally longer because the heat has to get through the thickness of the meat, not the total weight. The calculator handles that for you. Here are typical smoker times for common sizes:

 

Pork butt (bone-in)	225°F, no wrap	250°F, foil pan	250°F, no wrap	275°F, foil pan
6 lb	8½ hr	5¾ hr	7¼ hr	5 hr
8 lb	10½ hr	7 hr	8¾ hr	6 hr
9 lb	11¼ hr	7½ hr	9½ hr	6½ hr
10 lb	12 hr	8 hr	10 hr	7 hr
12 lb	13½ hr	9¼ hr	11½ hr	8 hr

 

These are smoker times only. Add your rest on top. Every cook varies 15-25% either way, so go by probe feel as you get close.

 

Weight and count. Put in the weight of a single butt from the package label, then pick how many you’re cooking. Two butts take about the same time as one. The calculator adds a few percent for the extra mass in the pit, but not double.

 

Smoker temperature. 250°F is the default and where I run most of my cooks. 225°F gives you a little more margin and more smoke. 275°F gets you done two to four hours sooner if you’re short on time.

 

Wrap. The default is a covered foil pan with butter and stock, which is how we do it in our Mexican pulled pork recipe. It gets you through the stall faster and leaves you with pan juices to mix back into the meat. Butcher paper is somewhere in between. No wrap gives you the best bark but the longest cook.

 

Serving time, rest and buffer. Set the time you want to eat. The calculator subtracts the rest and a safety buffer and tells you when the meat goes on and when to start the fire. Keep the buffer. A butt that finishes early can sit in a cooler for hours and still be perfect. One that finishes late means everyone is waiting on you.

 

At 250°F, wrapped once the bark sets, plan on about an hour per pound plus at least an hour of rest. A 9 lb bone-in butt takes about 7-8 hours on the smoker and around 9 with the rest. If you don’t wrap, figure closer to 1 hour 10 minutes per pound. At 225°F unwrapped, budget 1 hour 15 minutes per pound, which puts a 9 lb butt at about 11 hours.

 

250°F is what I recommend and what the calculator is built around. 225°F takes longer but gives you more margin and a little more smoke flavor. 275°F saves two to four hours if you need it. Pork butt is a lot more forgiving than brisket, so if you’re behind schedule you can push it to 300°F without ruining it.

 

Either way works. Wrapping in a covered foil pan with butter and stock once the bark is set (around 165-170°F internal) pushes through the stall, keeps the meat juicy and cuts about 20% off the cook time. You also get pan juices to mix back in. Butcher paper is a middle ground. No wrap gives you the deepest bark but the longest cook, and you may sit in the stall for a couple of hours.

 

Around 150-165°F internal, moisture evaporating off the surface cools the meat about as fast as the smoker heats it, and the temp stops climbing for a while, sometimes for hours. The calculator already builds typical stall time into the estimate for your wrap choice. Every butt stalls a little differently though, so once you’re close, check the meat with a probe rather than trusting the clock.

 

Pulled pork is done when it’s probe tender, which is usually 203-205°F. The thermometer should slide in and out with no resistance, and on a bone-in butt the blade bone should pull out clean with a twist. Use the temperature to know when to start checking, then go by feel.

 

At least 30 minutes, and an hour is better. If it finishes early, wrap it in foil and a couple of towels and put it in a dry cooler. It’ll stay above 140°F for four hours or more and the meat won’t suffer at all. That’s why the calculator includes a buffer.

 

No. Two butts on the pit take about the same time as one, since the heat has to travel through the thickness of each piece, not the combined weight. The calculator adds a few percent per extra butt to account for the pit recovering slower, and it doubles the yield.

 

You lose about half the raw weight to the bone, fat cap and moisture. Plan on 1/3 lb of pulled pork per person with sides, so a 9 lb bone-in butt feeds 11-14 people. The Yield box in the calculator does this math for you.

 

Bone-in. It holds together better on the smoker, the bone tells you when it’s done, and it’s usually cheaper per pound. If boneless is all you can get, tie it with butcher’s twine so it’s an even shape and cooks evenly. The calculator takes about 5% off the estimate for boneless.
