Smoking Time & Temperature Calculator
Pick a cut, enter its weight, and set your smoker temperature to estimate the cook time, a rest allowance, and the internal temperature to pull it at.
Estimated cook
Pull at ~203°F when a probe slides in like warm butter; rest wrapped for up to an hour.
How the estimate works
Each cut carries a typical low-and-slow rate in minutes per pound, measured at a 225°F chamber. The tool multiplies that rate by your weight, then scales it for your smoker temperature — a hotter pit shortens the cook. It adds a rest window and reports the target internal “done” temperature for that cut, because barbecue is finished by temperature, never by the clock.
Use the number to plan your day: when to light the smoker, when the stall might hit, and when to have the table ready. Then trust your thermometer for the actual pull.
Frequently Asked Questions
How long does it take to smoke a brisket?
As a planning figure, a whole packer brisket runs roughly 75 minutes per pound at 225°F, so a 12-pound brisket takes around 15 hours of cook time plus a rest. But brisket is done by temperature and feel, not the clock — pull it around 203°F internal when a probe slides in with no resistance. The stall, where evaporative cooling parks the temperature for hours, means the same brisket can finish an hour early or late.
Should I go by time or by internal temperature?
Always finish by internal temperature. Time estimates like the ones here are for planning your day — when to light the smoker, when to wrap, when guests should arrive. The only reliable doneness test is a thermometer in the thickest part of the meat. Two briskets of the same weight can finish an hour or more apart.
How does smoker temperature change the cook time?
Hotter runs faster. This tool scales its per-pound estimate from a 225°F baseline, so a cook at 275°F comes in noticeably shorter than the same cut at 225°F. Running hot-and-fast (275–300°F) is a legitimate way to finish a brisket or pork butt in less time; poultry actually benefits from higher heat for crisp skin.
Why do I need to rest the meat?
Resting lets the muscle fibers relax and reabsorb juices that would otherwise run out the moment you slice. Big cuts like brisket and pork shoulder can rest 30–60 minutes (wrapped, in a cooler) and stay hot; the estimate here adds a rest allowance to the total.
Planning estimates only. Cook to a safe internal temperature measured with a thermometer — times vary with weather, airflow, how often you open the lid, and the individual cut.
