About the Poultry FCR & Egg Production Calculator (feed cost and margin)
Two calculators for poultry farmers, each with its formula written out under the answer. For a broiler batch — the chicks placed, the birds at the end, their age, their live weight and the feed eaten — it works out the feed conversion ratio (FCR), the production efficiency factor (EPEF), liveability and mortality, the average weight, and, at your own prices, the feed cost and the full cost of a kg of live weight and the batch’s margin. It also tells you how much feed a batch still needs to reach a target weight.
For a laying flock — the hens housed, the days, the hens alive and the eggs collected — it gives hen-day and hen-housed egg production, eggs per hen, the feed a hen eats a day, feed per dozen eggs and kg of feed per kg of eggs, and the feed cost per dozen and margin over feed at your egg price. Weights can be in kg or lb, money in your own currency, and the labels can carry Hindi, Marathi, Gujarati, Punjabi, Telugu or Kannada beside the English. Nothing you type leaves your browser.
Without a pass, the free preview shows the FCR or the hen-day production in full, with the first step of each working; EPEF, liveability, the costs and margins, the feed still needed, the other figures and copying the results need a Pro pass.
How to use it
- Choose Broilers or Layers, your currency and whether you weigh in kg or lb.
- Broilers: type the chicks placed, the birds at the end (sold, or alive and weighed — not the dead or culled), their age in days, their live weight (the total, or the average of a bird) and the feed eaten. Layers: type the hens housed at the start, the days in the period, the average hens alive (or the hen-days) and the eggs collected.
- Open Costs and margin to add your feed price, chick price, other costs and sale price (or your egg price per egg, dozen, tray or 100). Every price is your own: the calculator has no market rates.
- Read the answers and, under How it is worked out, each formula with your numbers in it. Copy the results (with a pass, or after unlocking this result), or press Continue in the Poultry Batch Register to keep the batch and record it day by day.
Examples
5,000 chicks placed · 4,800 birds sold weighing 10,080 kg · 16,632 kg of feed eaten · 38 days
FCR 1.650 · EPEF 322 · liveability 96.00% (mortality 4.00%, 200 birds) · average weight 2.100 kg · 3.465 kg of feed a bird
EPEF = 96.00 × 2.100 ÷ (38 × 1.650) × 100 = 321.5, shown as 322.
Feed 40 a kg · chicks 35 each · other costs 50,000 · sold at 100 a kg of live weight
Feed cost 66.00 a kg (FCR × feed price) · full cost 88.32 a kg · margin 117,720 (11.68 a kg, 24.53 a bird)
4,800 birds · target 2.3 kg · expected FCR 1.70 at that weight · 12,000 kg eaten so far · 50 kg bags
18,768 kg at the target − 12,000 kg = 6,768 kg still needed: 136 bags
10,000 hens housed · 9,800 alive on average · 264,600 eggs · 33,810 kg of feed · eggs of 60 g
Hen-day 90.00% · hen-housed 88.20% · 26.46 eggs per hen housed · 115.0 g of feed a hen a day · 1.533 kg of feed per dozen · 2.130 kg of feed per kg of eggs
Common uses
- Closing a broiler batch: its FCR, EPEF and what a kg of live weight really cost before you sell or settle with the company.
- Checking a contract batch’s FCR and mortality before the integrator’s statement arrives.
- Planning how many bags of feed a batch still needs for the weight you want to sell at.
- Watching a laying flock’s hen-day production and feed per dozen eggs week by week, and its margin over feed at today’s egg price.
The formulas
- FCR = feed eaten ÷ live weight, both in the same unit (Ross Broiler Management Handbook, Appendix 4). A lower FCR means less feed for each kg of bird.
- EPEF (the production efficiency factor, PEF) = liveability (%) × average live weight (kg) ÷ (age in days × FCR) × 100 (same appendix; its example: 35 days, 2.296 kg, 97.20% livability and FCR 1.399 give 456). The handbook notes it is heavily biased by daily gain, so compare batches at similar ages.
- Adjusted FCR = FCR + (target weight − actual weight) ÷ 4.5 kg (10 lb), to compare batches at one weight; the handbook warns that adjusting further than about 0.227 kg (0.5 lb) distorts the comparison.
- Liveability = birds at the end ÷ chicks placed × 100; mortality is the rest (dead and culled birds).
- Hen-day production = eggs ÷ hen-days × 100, where hen-days are the hens alive each day added up (a survivor basis); hen-housed production = eggs ÷ (hens housed × days) × 100, counted on the hens put in the laying house at point of lay (Poultry Hub Australia, poultry husbandry terms).
- Feed per dozen eggs, feed per 10 eggs and kg of feed per kg of eggs (feed ÷ the eggs’ weight) are the measures layer performance guides print (Hy-Line Brown performance guide).
Feed still needed for a target weight
Feed at the target = birds × target weight × the FCR you expect at that weight; the feed still needed is that less the feed eaten so far, and the bags are rounded up. The expected FCR is yours: take it from your own past batches or the breeder company’s performance objectives for your breed and sex, at the same weight. The answer is a planning figure — weigh a sample of birds as the batch grows and work it out again.
Costs and margin
- Feed cost a kg of live weight = feed cost ÷ live weight, which is the same as FCR × the price of a kg of feed.
- Cost a kg adds the chicks and every other cost you type; margin = live weight × your sale price − all costs.
- Layers: feed cost per dozen = feed cost ÷ (eggs ÷ 12); the margin over feed is the income from the eggs you can sell (cracked ones left out) less the feed cost, before chicks or pullets, labour and other costs.
Limitations
- No market or company prices: every price is the one you type.
- It works out performance from the figures you give it; it does not formulate feed or suggest any medicine or dose.
- EPEF is made for broiler chickens; FCR, mortality and the egg measures work for any poultry, but compare ducks, quail or country birds only with their own kind.
- One batch or one period at a time. To keep every batch day by day, use the Poultry Batch Register.

Frequently asked questions
What do I get without a pass?
Without a pass, Poultry FCR & Egg Production Calculator (feed cost and margin) shows the FCR or the hen-day production in full, with the first step of each working; every other figure is hidden. Until you unlock it, the result can’t be copied. A Pro, Premium or Ultimate pass, a one-time payment that never renews, unlocks the full result. The pricing page lists the passes and their prices.
What is a good FCR or EPEF?
It depends on the breed, sex, age and weight of the birds, so compare yours with the performance objectives your breeder company publishes for your breed at the same age or weight, and with your own past batches. The calculator shows the figure and how it was worked out; it does not grade it.
Should the dead birds’ weight be in the FCR?
This calculator uses the standard FCR: all the feed eaten ÷ the live weight of the birds at the end. Dead birds ate feed but add no weight, so high mortality raises the FCR. If your contract counts it another way, the company’s statement says how; to compare batches sold at different weights, use the adjusted FCR here.
What is the difference between hen-day and hen-housed production?
Hen-day production divides the eggs by the hens alive each day, so it is not lowered when hens die. Hen-housed production divides by all the hens housed at the start, so deaths lower it: it shows what the flock you paid for produced.
Can I use pounds instead of kg?
Yes. Choose lb: FCR and the percentages come out the same, the EPEF formula turns the average weight into kg as it requires, and the adjusted FCR uses the 10 lb factor. Layer feed a day is then shown per 100 hens, as US guides give it. The example figures switch unit with you; a number you typed is kept as you typed it, so choose the unit before you type.
How do I count hen-days?
Add up the hens alive on each day of the period. If you know the average number of hens alive, average × days gives the same: switching Hens alive as between an average and hen-days turns the number you typed into the other one. The Poultry Batch Register counts them day by day from your daily entries.
What does “Continue in the Poultry Batch Register” do?
It hands the batch to the register on this device — the chicks placed, the age, the birds lost, the feed eaten and the average weight (or the hens housed) — so you can keep it day by day there. Nothing is uploaded.
