Pellet Smoker Consumption Calculator

Enter your burn rate and cook time to estimate pellet usage.

How it is calculated

pellets (lb) = burn rate × hours, bags = ceil(pellets ÷ 20) and cost = pellets × price. Burn rate is in pounds per hour, hours is the total cook time, and the price is per pound, not per bag. The bag count always rounds up to whole 20-lb bags, so 20.5 lb needs 2 bags. The pellet weight is shown to one decimal and the cost in US dollars. Leaving the price empty gives a cost of $0.00; burn rate and hours must be above zero, and a negative price returns no result. The burn rate is your own figure and varies with temperature, wind and the smoker model.

Worked example

A smoker burns 1.5 lb of pellets an hour and the cook runs 14 hours. Pellets = 1.5 × 14 = 21.0 lb. Bags = 21 ÷ 20 = 1.05, rounded up to 2 bags. At $1.20 per pound, cost = 21 × 1.20 = $25.20. The tool shows 21.0 lb, 2 bags and $25.20.

Common mistakes

  • Entering the price of a whole 20-lb bag as the price per pound; divide the bag price by 20 first, otherwise the cost is 20 times too high.
  • Using one burn rate for the whole cook when a long smoke at 225 degrees and a hot finish at higher temperature burn pellets at different speeds.
  • Forgetting preheating and startup time in the hours figure.
  • Buying exactly the number of bags shown when the pellet need is just under a bag boundary; 19.9 lb is one bag with almost no reserve.
  • Typing the burn rate in kilograms per hour; the calculator expects pounds, and the answer is in pounds too.

About this calculator

Pellet smokers burn compressed wood pellets at a fairly steady burn rate (pounds per hour) that depends on the target cooking temperature — higher temps mean the auger feeds pellets faster to keep the fire going. Multiplying that burn rate by the expected cook time gives a solid estimate of total pellets needed for the session.

Since pellets are typically sold in 20-lb bags, this calculator also converts the total pounds needed into bags to buy, plus an estimated fuel cost — handy for planning a long low-and-slow brisket or ribs cook without running out of pellets halfway through, or for budgeting fuel cost for a catering job.

    The burn rate is the number that matters, and you can measure your own: weigh the pellets you load, run a cook at your usual temperature for a few hours, then weigh what is left. The tool only counts total pounds and bags, so also compare the pellet figure with your hopper capacity to see how many refills a long cook needs. What smoker do you use, and what burn rate did you measure at low and slow temperatures?
