Serve Time Planner
Quick answer: Start from the time you want to eat, subtract a safety buffer, the rest time and the estimated cook time, and you get when the meat goes on. Subtract smoker preheat time to get when to light the fire. Build in a big buffer, because finishing early and holding safely is far easier than serving late.
How it works
Meat-on time = serve time − buffer − rest − (weight × minutes per lb). Fire-up time = meat-on time − preheat. If the result crosses midnight, the planner flags it as the day before. Rest and hold safely; see rest and hold for what USDA FSIS says about keeping hot food hot. The cook is still done only when a thermometer shows at least the safe minimum on the USDA FSIS chart.
Worked example
Figures below are illustrative examples (2026-10-29), not quotes or guarantees.
Assumptions: dinner at 6:00 pm, a 9 lb pork butt, 90 min/lb planning rate (invented input), 60 min rest, 120 min buffer, 45 min preheat. Cook = 810 min (13 h 30 min). Meat on at 1:30 am, smoker lit at 12:45 am. Many cooks prefer a slightly hotter pit to avoid an overnight start; recalculate with your own rate.
FAQ
What if it finishes early?
Hold it hot and keep checking that it stays hot; see rest and hold.
What if it is running late?
Keep cooking to a safe temperature. Never pull meat early to meet a schedule.
Where do I get the minutes per lb?
From your own cook logs or the smoking time calculator guide.
