Llama Calculator — Pack Capacity & Feed Requirements
Plan a llama pack trip or estimate feed costs: enter the herd size, average body weight, the pack-weight percentage, and daily feed rate to get per-animal and whole-herd estimates — including how much net payload remains after feed for the trip.

How does this calculator work?
A llama can carry roughly 25–30% of its body weight and needs about 1.5–2% of its body weight in dry-matter feed per day. Multiply by herd size and trip days to get total pack capacity and total feed needed. Subtract feed from pack capacity for net payload available for gear.
Formula
How this is calculated
Llamas are well-suited pack animals for mountain terrain and can safely carry 25–30% of their body weight on a day trip; experienced handlers typically cap loads at 25% for multi-day treks to reduce stress on the animal. The pack weight per llama is simply the body weight multiplied by the chosen percentage.
Dry-matter feed intake for llamas is approximately 1.5–2% of body weight per day. This is the weight of feed after moisture is removed — dried pellets or hay. For planning a trip, total feed for all animals over all days is subtracted from the gross pack capacity to give the net payload available for other gear.
These figures are evidence-based guidelines from the Llama and Alpaca Community and Backcountry Hunters & Anglers resources, but individual animals vary with age, conditioning, altitude, and terrain. Younger, older, or less-conditioned animals should carry less. Always assess each animal on the day and monitor for signs of fatigue.
Frequently asked questions
A healthy, conditioned adult llama can carry 25–30% of its body weight. A 150 kg llama can safely carry 37–45 kg of pack load. For extended trips at altitude, most handlers keep loads closer to 25% to protect the animal's joints and stamina.
Llamas are browsers and grazers and will forage during rest stops in areas with adequate vegetation. When grazing is insufficient, handlers typically pack pelleted llama feed or cubed hay. Allow roughly 1.5–2% of body weight per day in dry matter as a planning figure, though grazing will reduce how much you need to carry.
Yes, and the "net carry capacity" shown above accounts for this: it subtracts the total feed needed for the trip from the gross pack capacity, leaving the payload available for camping gear and supplies. For a 3-day trip with a 150 kg llama at 25% pack and 2% feed rate, about 9 kg of the 37.5 kg load is feed, leaving 28.5 kg for gear.
