Why people run the numbers

Eggs aren’t the only cost.

Many new keepers start with feed and miss the coop, run, bedding, equipment and the weeks before young hens lay. This calculator puts those costs next to the price on your grocery receipt.

01 / STARTUP

The coop bill comes first

Enter the coop, predator-safe run, equipment and hens together. They can change the first-year number more than feed does.

02 / EVERY MONTH

Feed keeps adding up

Enter the price of your bag and how long it lasts. Add bedding, grit and routine care to see the ongoing monthly cost.

03 / WHAT YOU EAT

Compare the eggs you buy

Compare with the type you actually purchase. The answer changes if you buy budget, free-range or organic eggs.

Open math, no mystery number

How we calculate it

Monthly feed is estimated from the feed bag’s price and how many days it lasts your flock. Add your other recurring costs to get your monthly running cost.

First-year cost per dozen = (monthly cost × 12 + setup cost) ÷ first-year dozens

For the first-year egg estimate, enter the weeks your flock is expected to lay. Young chicks may need several months before their first eggs; point-of-lay birds need less time. The tool does not assume backyard eggs automatically save money.

  • Feed bag duration is your own estimate; it includes your flock’s actual wastage.
  • Monthly extras are user-entered. Add a realistic allowance for supplies and routine care.
  • Does not include your time, major veterinary emergencies, replacement hens or local permit costs.
  • Use the result for budgeting, not animal-care advice or a guarantee of savings.

Before you decide

Questions new keepers ask.

Are backyard chickens cheaper than buying eggs?

It depends on your setup, feed, egg production and the eggs you compare them with. Many small-flock owners keep chickens for freshness, enjoyment or self-sufficiency as well as cost. Use your local prices instead of assuming a saving.

What should I include in setup costs?

Include the coop, run, predator protection, feeder, waterer, bedding supplies and the hens. If you start with chicks, add brooder supplies and feed before laying begins.

Why compare with the eggs I actually buy?

A backyard egg compared with the cheapest grocery dozen gives a different result from one compared with organic or pasture-raised eggs. Enter your usual price for a useful household comparison.

What is included in ongoing cost per dozen?

It uses the feed and other monthly costs you enter, annualized over 12 months, then divides that amount by estimated yearly egg production. It excludes one-time setup costs.

Does the estimate include veterinary care or my time?

No. Add routine supplies and care to monthly extras if you want to budget for them. The estimate does not include your labor, major veterinary emergencies, replacement birds, local permits or the value of unsold eggs.

Does the calculator save my inputs?

No. It runs in your browser and does not send your flock size or costs to a server.
