How to Use Alpaca Calculator

  1. Enter herd size and average weight — kg or lb.
  2. Set daily dry-matter % — Default 1.5% of body weight.
  3. Choose planning period — 7, 30, 365 days or custom.

  5. Read the plan — The Alpaca Calculator outputs daily / monthly / annual feed, capacity and cost.

Formula & Theory — Alpaca Calculator

daily_dm   = herd × avg_weight_kg × feed_pct / 100
period_dm  = daily_dm × period_days
hay_cost   = period_dm × hay_price
capacity   = pasture_acres × forage_yield_kg / (daily_dm × 365)

Frequently asked questions about Alpaca Calculator

How much hay does an alpaca eat per day?

An adult alpaca eats roughly 1.5% of its body weight in dry matter daily, about 1–1.5 kg. The Alpaca Calculator multiplies herd size, weight and percentage.

How many alpacas can I keep per acre?

On good pasture you can stock 5–8 alpacas per acre. The Alpaca Calculator divides annual forage yield by annual feed demand to find a carrying capacity.

What does the cost estimate include?

Hay and optional supplement at user-set prices. Vet and shearing costs are not included — combine with the Dog Cost Calculator pattern or a spreadsheet for full life-cycle costs.

Can I plan for younger alpacas (crias)?

Yes — enter the average weight of your herd; crias and weanlings drag the average down naturally.

Is my data stored?

No, all calculations run locally.
