Pellet Consumption Chart: Pounds Per Hour by Temperature

Updated 2026-08-14 Researched, not tested in person

Quick answer

A pellet grill burns about 0.85 lb of pellets per hour at 225F, 1.1 lb per hour at 250F and 1.4 lb per hour at 275F, so a 20 lb bag lasts roughly 24, 18 and 14 hours respectively. A 14 lb brisket at 250F takes about 17 hours 30 minutes and roughly 19 lb of pellets. Cold or windy conditions raise every figure by up to 70 percent.

Pellet consumption is the number that decides whether you run out of fuel at 3am. A pellet grill burns roughly 0.85 lb per hour at 225°F, 1.1 lb per hour at 250°F and 1.4 lb per hour at 275°F, which means a standard 20 lb bag covers about 23.5 hours, 18.2 hours or 14.3 hours respectively. A 14 lb brisket at 250°F takes about 17 h 30 m and eats roughly 19.3 lb of pellets.

A definition worth stating plainly: burn rate is a function of grate temperature, not of how much food is on the grate. The controller is fighting heat loss through the walls and out the chimney, and a loaded chamber costs you very little extra fuel. What does cost you is cold air, wind and opening the lid.

Pellet burn rate by grate temperature, with bag life and fuel cost. Cost is calculated at $1.13 per pound, the current price of a 15 lb bag of the house blend below.
Grate temp	Setting	lb per hour	Hours per 20 lb bag	Hours per 40 lb bag	Cost per hour	Cost per 8 h cook	What it is for
180°F	Smoke setting	0.6	33.3 h	66.7 h	$0.68	$5.44	Lowest burn rate and the heaviest smoke, because the auger cycles slowly.
225°F	Low and slow	0.85	23.5 h	47.1 h	$0.96	$7.70	The standard barbecue setting and the one most cooks live at.
250°F	Standard barbecue	1.1	18.2 h	36.4 h	$1.25	$9.97	Slightly faster cooks for a modest pellet cost.
275°F	Hot and fast	1.4	14.3 h	28.6 h	$1.59	$12.69	Popular for ribs and poultry where skin and bark matter.
325°F	Roasting	1.9	10.5 h	21.1 h	$2.15	$17.22	Poultry and anything you want browned rather than smoked.
400°F	Baking and searing	2.5	8 h	16 h	$2.83	$22.65	Approaching the ceiling of most pellet grills.
450°F	Maximum	3	6.7 h	13.3 h	$3.40	$27.18	Sustained maximum output. A 20 pound hopper is under 7 hours here.

Why does a pellet grill burn so much more at high temperature?

Because heat loss scales with the difference between the chamber and the air outside it. Holding 450°F on a warm, above 70f, sheltered day means maintaining a gap of several hundred degrees across a thin steel wall, and the only way a pellet grill can do that is by feeding the burn pot faster. The rate at 450°F is 5 times the rate on the smoke setting, which is a much steeper curve than the temperature difference alone suggests.

That curve is also why the smoke setting is the cheapest heavy smoke available on any cooker. At 180°F the auger cycles slowly, the pot smoulders, and you get maximum smoke output for $0.68 an hour. The catch is that 180°F is below any useful cooking temperature, so it is a phase at the start of a cook rather than a way to cook. Never hold food at that temperature for hours in the hope of extra flavour, because it parks the meat close to the top of the danger zone.

How much extra do cold and wind cost you?

A single-wall pellet grill in freezing wind can burn 70 percent more than the same grill in mild sheltered conditions, and in the worst cases it will not hold 225°F at all. This is the specification argument for a double-walled or insulated cooker, and it only matters if you actually cook through winter.

Pellet burn rate in pounds per hour, adjusted for conditions. Multiply the mild-weather rate by the factor in the column heading.
Grate temp	Warm, above 70F, sheltered (1x)	Mild, 50F to 70F (1.15x)	Cool, 32F to 50F (1.35x)	Freezing or windy, below 32F (1.7x)	20 lb bag, freezing
180°F	0.6 lb/h	0.69 lb/h	0.81 lb/h	1.02 lb/h	19.6 h
225°F	0.85 lb/h	0.98 lb/h	1.15 lb/h	1.44 lb/h	13.8 h
250°F	1.1 lb/h	1.26 lb/h	1.49 lb/h	1.87 lb/h	10.7 h
275°F	1.4 lb/h	1.61 lb/h	1.89 lb/h	2.38 lb/h	8.4 h
325°F	1.9 lb/h	2.18 lb/h	2.57 lb/h	3.23 lb/h	6.2 h
400°F	2.5 lb/h	2.88 lb/h	3.38 lb/h	4.25 lb/h	4.7 h
450°F	3 lb/h	3.45 lb/h	4.05 lb/h	5.1 lb/h	3.9 h

Wind is the variable people underestimate. Moving air strips heat off the outside of the cooker far faster than still cold air does, which is why a sheltered 20°F morning can be easier than an exposed 40°F one. A physical windbreak on the upwind side is worth more than any accessory, and it costs nothing. Welding blankets and insulated jackets work as well, provided they are rated for the job, kept clear of the hopper and the chimney, and never left on a grill running above about 300°F.

Two cheaper habits help as much as either. Keep the lid shut, because every opening dumps the chamber and the controller answers by feeding the pot. And run the grill with a full hopper in the cold, since a nearly empty hopper of chilled pellets makes the auger work against a bridged mass rather than a flowing one.

How many pellets does a specific cook take?

These are computed by multiplying the cook time for each cut by the burn rate at that grate temperature, so the fuel figure and the time figure come from the same source. The cold column applies the 1.7x freezing multiplier, which is the number to plan against if you cook in winter.

Fuel needed for common cooks, computed from cook time multiplied by burn rate. Add a 20 percent margin so you are never scraping the hopper at the end.
Cook	Weight	Grate temp	Cook time	Pellets, mild	Pellets, freezing	Fuel cost, mild
Beef brisket, whole packer	14 lb	250°F	17 h 30 m	19.3 lb	32.7 lb	$21.80
Beef brisket, whole packer	14 lb	225°F	21 h	17.8 lb	30.3 lb	$20.22
Pork shoulder, Boston butt	8 lb	250°F	12 h	13.2 lb	22.4 lb	$14.95
Pork spare ribs, St. Louis cut	Per rack or bird	275°F	4 h 15 m	5.9 lb	10.1 lb	$6.74
Whole turkey	15 lb	275°F	6 h 45 m	9.5 lb	16.1 lb	$10.70
Whole chicken	5 lb	275°F	2 h 30 m	3.5 lb	6 lb	$3.96
Chicken wings	Per rack or bird	275°F	1 h 15 m	1.8 lb	3 lb	$1.98
Beef short ribs, plate	5 lb	250°F	6 h 30 m	7.2 lb	12.2 lb	$8.10

Read the brisket rows together, because they make the trade explicit. Running a 14 lb packer at 225°F instead of 250°F adds hours to the cook and adds pellets to the bill, and it does it for a difference in the finished brisket that most people cannot identify blind. That is the fuel-side argument in 225 vs 250 vs 275, and it is a real one on a cooker that meters its own fuel.

Will your hopper hold the whole cook?

Hopper capacity is the specification that decides whether an overnight cook needs an alarm. Most backyard pellet grills carry 18 to 20 lb, portable models carry as little as 7 lb, and large competition cookers carry 40 lb. Match that against the burn rate and you know whether you can sleep.

Runtime in hours from a full hopper, by hopper size and grate temperature, in mild conditions.
Grate temp	7 lb hopper	18 lb hopper	20 lb hopper	40 lb hopper
180°F	11.7 h	30 h	33.3 h	66.7 h
225°F	8.2 h	21.2 h	23.5 h	47.1 h
250°F	6.4 h	16.4 h	18.2 h	36.4 h
275°F	5 h	12.9 h	14.3 h	28.6 h
325°F	3.7 h	9.5 h	10.5 h	21.1 h
400°F	2.8 h	7.2 h	8 h	16 h
450°F	2.3 h	6 h	6.7 h	13.3 h

Treat those numbers as an upper bound and knock 20 percent off. Augers do not reliably feed the last few pounds, the shape of the hopper leaves pellets stranded in the corners, and a hopper that runs dry mid-cook does not just pause: the fire goes out, the controller throws an error, and restarting means clearing the burn pot before you can relight. Fill it before you start, top it before you sleep, and use the pellet usage calculator to work out your own cook rather than reading across from these examples.

A fire that goes out is a food safety problem, not an inconvenience

If the hopper empties overnight and the fire dies, the food cools into the 40°F to 140°F danger zone and stays there. Food must not accumulate more than 4 hours in that range across its whole life, and only 2 hours above 90°F ambient. If you do not know how long the fire was out, throw the food away. There is no home test for this, and reheating does not remove the toxins some bacteria leave behind.

Never store pellets, a bag or a hopper cover anywhere near the chimney or firebox, and never run an insulated blanket that is not rated for the cooker. Clean the burn pot and grease tray regularly: a grease fire in a pellet grill is fast, and the fuel is sitting a few feet away.

Fuel planning never overrides temperature. All poultry is still 165°F, ground meat 160°F, whole cuts of beef, pork, lamb and veal 145°F with a 3 minute rest, and leftovers 165°F. Brisket and pork butt run to about 203°F for collagen rather than for safety, and they were safe many hours before that. Verify every cook with a calibrated thermometer.

How should you store pellets so you are not buying them twice?

Pellets are compressed sawdust bound by the wood own lignin, with no glue holding them together. Moisture is the enemy: a pellet that absorbs humidity swells, loses its structure and turns back into sawdust, which jams augers and produces a weak, smoky, uneven burn. A bag left open in a damp shed for a season is often unusable.

Sealed containers, not open bags. A lidded plastic bin with the bag inside it costs very little and effectively ends the problem.
Empty the hopper if the grill will sit unused for more than a week or two, especially in a humid climate. Vacuum out the fines while it is empty.
Buy the size you will use. A 40 lb bag is cheaper per pound and worthless if half of it degrades before you burn it.
Keep flavours separate and labelled. Mixed leftovers in a bin become an unrepeatable blend, which is fine until you cook something good and cannot do it again.
Check before a long cook. Squeeze a handful. Good pellets are hard and snap; degraded ones crumble and leave dust on your palm.

One more habit worth building: never mix a new brand into a half-full hopper before a long cook. Different pellets have different densities and ash characteristics, and a brisket overnight is the wrong time to discover that a blend bridges in your auger. Run a short cook on a new bag first. The wood pellet guide covers which blends are worth paying for, and the pellet grill guide covers hopper size and insulation as buying specifications.

Frequently asked questions

How many pellets does a pellet grill use per hour?

About 0.6 lb per hour on a smoke setting near 180F, 0.85 lb per hour at 225F, 1.1 lb per hour at 250F, and 1.4 lb per hour at 275F. Above that it climbs steeply: roughly 1.9 lb per hour at 325F and 3 lb per hour at a sustained maximum. Those are figures for a well-sealed grill in mild weather, and cold or windy conditions can raise every one of them by up to 70 percent.

How long does a 20 lb bag of pellets last?

About 24 hours of cooking at 225F, 18 hours at 250F, or 14 hours at 275F. On a smoke setting near 180F a 20 lb bag stretches to roughly 33 hours, and at a sustained 450F it is gone in under 7. In practical terms one bag covers a long brisket and most of a second cook, which is why buying pellets one bag at a time is a false economy if you cook regularly.

Do pellet grills use more pellets in cold weather?

Yes, and the effect is larger than most people expect. A single-wall uninsulated grill loses heat to the surrounding air continuously, so the controller runs the auger harder to hold the same grate temperature. Plan on about 15 percent more between 50F and 70F, 35 percent more between 32F and 50F, and up to 70 percent more below freezing or in wind. Wind matters more than air temperature alone.

How much does it cost to run a pellet grill?

At roughly a dollar a pound for a house blend, holding 225F costs about a dollar an hour in fuel, and a full brisket cook runs somewhere between fifteen and twenty dollars of pellets. That is meaningful next to the cost of the meat but small next to buying the same brisket cooked. Premium single-species pellets can double the fuel cost without changing the cook time at all.

Can I leave pellets in the hopper between cooks?

Not for long. Pellets are compressed sawdust held together by the wood own lignin and they absorb moisture from humid air, swell, and turn to sawdust in the auger, which is the most common cause of a pellet grill jamming or failing to start. Empty the hopper if the grill will sit for more than a week or two, and store pellets in a sealed container with the lid closed rather than in an open bag in a shed.

Does the pellet brand change how many pellets you burn?

A little. Denser, lower-moisture pellets burn more slowly and leave less ash, so a premium bag can last modestly longer than a cheap one and needs fewer burn-pot cleanouts. The differences are in the range of 10 to 15 percent rather than anything dramatic. What changes fuel use far more is grate temperature, ambient weather, wind exposure and how often the lid comes open.

Cook times and temperatures are researched guidance, not a food-safety authority. Every figure on this page is an estimate: smokers, ambient weather, humidity and the individual cut all move it. Food is safe when a calibrated instant-read thermometer says so, never when a clock or a chart does. Keep food out of the 40°F to 140°F danger zone, observe the 4 hour rule, and follow current USDA safe minimum internal temperatures. If you are cooking for anyone pregnant, very young, elderly or immunocompromised, cook to the USDA minimums rather than to a preference-based doneness temperature.
