Layer farming profitability depends on balancing a long list of small recurring costs — feed, chicks, vaccination, labor — against egg output that varies with hen age, housing, and season. This calculator totals your revenue from Grade A and standard eggs across the production cycle and subtracts every cost category to show your net profit per hen and per cycle.
Revenue = Number of Hens × Eggs per Hen per Year × (Selling Price ÷ 12) × Grade A Share Adjustment, while Total Cost = Feed Cost + Chick Cost + Vaccination/Medicine + Labor & Utilities, each scaled to the production cycle length. Net profit is simply revenue minus total cost.
| Metric | Typical Range |
|---|---|
| Eggs per hen per year | 280-320 (commercial layers) |
| Peak lay rate | 90-95% (weeks 25-40) |
| Feed intake per hen/day | 110-120 g |
| Productive laying life | 72-80 weeks before culling |
For 500 hens laying 300 eggs/year at PKR 350/dozen, with 85% Grade A eggs: annual egg revenue ≈ 500 × 300 ÷ 12 × 350 × 0.85+0.15(lower rate) ≈ PKR 4.3-4.5 million. Against feed cost of roughly PKR 2.4 million/year (500 hens × 115 g × 365 × PKR 115/kg) plus chick, medicine, and labor costs, most well-run layer units net 15-25% margin over a full cycle.
A well-managed commercial layer produces 280-320 eggs per year, with peak lay rates of 90-95% between weeks 25 and 40 of age, tapering off gradually toward the end of the laying cycle.
Under good nutrition and housing, 80-90% of eggs should qualify as Grade A (standard size, clean, undamaged shell). A drop below 75% often signals calcium deficiency, heat stress, or aging flock.
Most commercial operations cull and replace flocks at 72-80 weeks of age, when lay rate has dropped enough that feed cost per egg exceeds what a new pullet flock would cost.
Yes — cage systems generally produce more eggs per unit feed than free-range or deep-litter systems, but free-range eggs often command a 20-40% price premium, so the more profitable system depends on your local market.
