Backyard egg cost calculator

How much does a dozen of your own eggs really cost? Enter your flock, your feed and your other costs. The numbers below are examples: replace them with yours.

Hens in the flock

Eggs per week (whole flock)

Currency

Feed weight unit

Price of one feed bag

Bag weight (lb)

Feed per hen per day (lb)

Other costs per month (bedding, treats, supplements)

Store price for a dozen eggs

Coop and setup cost (optional)

A laying hen typically eats about 0.11 kg (roughly 1/4 lb) of feed a day, but it varies with breed, season and treats. Weigh what you actually feed for a better estimate.

Feed used per month
Feed cost per month
All costs per month
Eggs per month

Estimate only. Results come from the numbers you enter and simple averages (a month is 30.44 days; 52/12 weeks). Real costs change with season, laying rate, waste, vet or other bills and the price of feed. Currency is only a label: no exchange rates are applied.

How the calculation works

Feed used per month = hens x feed per hen per day x 30.44 days.
Feed cost per month = feed used x (bag price / bag weight).
All costs per month = feed cost + other costs.
Eggs per month = eggs per week x 52 / 12. Dozens per month = eggs per month / 12.
Cost per dozen = all costs per month / dozens per month.
Coop payback (if you enter a coop cost) = coop cost / (dozens per month x store price - all costs per month), only when that monthly figure is above zero.

The calculator does not count the value of your time, manure for the garden, or the cost of chicks and the coop, unless you enter the coop cost above. Those choices are yours.
