How to Use This Calculator
- Enter Your Brisket Weight (lbs): Start by entering your brisket weight — this is the primary input for the calculation.
- Fill In Additional Details: Complete the remaining fields: smoker temperature, cut type, number of guests. Each value refines the calculation for greater accuracy.
- Click Calculate: Hit the Calculate button to run the numbers. Results appear instantly below.
- Review Your Results: Check your total cook time, rest time, start by. Use these figures to inform your next decision or compare against alternative scenarios.
How It Works
Brisket cook time depends on weight, smoker temperature, and the dreaded "stall" — a plateau around 150-170°F where the meat sweats and stalls for hours. Planning ahead is key to serving on time.
The basic rule:
- At 225°F: estimate 1.5-2 hours per pound
- At 250°F: estimate 1-1.5 hours per pound
- At 275°F: estimate 45-75 minutes per pound
- Always add 1-2 hours for rest (wrapped, in a cooler) — this is non-negotiable
- Plan for ⅓ lb cooked brisket per person (½ lb raw weight) to account for shrinkage
Brisket loses 30-40% of its weight during cooking. A 14-lb packer yields about 8-9 lbs of sliced meat. The rest period is when collagen finishes converting to gelatin — skip it and you'll have dry brisket.
Tips & Considerations
- Double-check your brisket weight before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both total cook time and rest time — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to perfect your recipes.
- If you're unsure about your number of guests, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How long does a 14-lb brisket take to smoke?
At 250°F, a 14-lb full packer brisket takes approximately 14-21 hours including the stall. Add 1-2 hours for resting. Start the night before if you're serving for lunch or dinner the next day.
What is the brisket stall?
The stall occurs around 150-170°F internal temperature when evaporative cooling from the meat's surface moisture balances the heat input. It can last 2-6 hours. Wrapping in butcher paper or foil (the Texas Crutch) pushes through the stall faster.
How much brisket do I need per person?
Plan for ½ lb raw brisket per person. Brisket loses 30-40% of its weight during cooking, so ½ lb raw yields about ⅓ lb cooked meat — a generous serving. For a crowd with sides, you can get away with slightly less.
Should I wrap my brisket?
Wrapping in butcher paper or foil at 165°F internal temp speeds up cooking by 2-3 hours and helps push through the stall. Butcher paper allows some bark formation while foil (Texas Crutch) is faster but can soften the bark.
How long should brisket rest?
Rest brisket for at least 1 hour, ideally 2-4 hours. Wrap it in butcher paper, then towels, and place in a cooler (no ice). It will stay above 140°F for up to 6 hours. Resting lets juices redistribute throughout the meat.
What internal temperature is brisket done?
Brisket is done between 195-205°F internal temperature, when the probe slides in like butter. Temperature alone isn't enough — the probe test (feeling tenderness when you insert a thermometer) is the true indicator of doneness.
