How much charcoal, pellet, or wood your next cook actually needs — dialed to your cooker, temp, and cook time.
Buy the "bags to have on hand" number, not the exact pounds — running out mid-brisket is the only real sin here. Add a 20% buffer for overnight cooks or if your cooker runs hungry.
Rates assume a 250°F baseline and scale with target temperature and conditions. Every cooker is a little different; after two or three cooks you'll know yours better than any calculator.
