Quick answer A US$12 bale weighing 20 kg costs US$0.60 per kg. Two horses eating 10 kg each a day use a bale a day and cost US$12 a day, about US$365 a month and US$4,380 a year. Enter your bale price, weight and the hay you feed.

Prices the hay you enter; it does not say how much a horse should eat. Ask your vet or an equine nutritionist.

Example values are illustrative; this result is produced by the same calculator above.

How we calculate it

price per kg = bale price ÷ bale kg; cost per day = price per kg × kg fed per horse per day × horses; bale lasts = bale kg ÷ daily kg

Understanding your result

To price hay, divide the bale price by the bale weight to get the price per kilogram, then multiply by the kilograms you feed each day. A US$12 bale of 20 kg costs US$0.60 per kg.

Two horses eating 10 kg each a day use 20 kg, one bale a day, so hay costs US$12 a day, about US$365 a month and US$4,380 a year.

The calculator does not say how much hay a horse should eat, which depends on weight, workload and the rest of the diet. Ask your vet or an equine nutritionist. It prices the amount you enter.

Common mistakes

  • Using the label weight of a bale without checking it.
  • Leaving out wasted hay.
  • Forgetting other feed and bedding.
  • Entering the total for all horses as the amount per horse.
  • Not allowing for price changes through the year.

Good to know

  • Bale weight varies; weigh a few.
  • Use the Horse Weight Calculator to estimate your horse's weight.
  • Talk to your vet if your horse is losing or gaining weight.

When to talk to your vet

  • Your horse is losing or gaining weight
  • Before changing a horse's diet
