How the calculation works
Daily feed = birds × intake per bird (112 g for layers)
Layers (monthly): profit = monthly eggs × egg price − monthly feed cost − other costs
Broiler/sonali (per cycle): profit = total meat × price per kg − (feed + chicks + other costs)
- Eggs: surviving birds × 94% peak = eggs per day; × 30 = eggs per month.
- Meat: surviving birds × average weight (2.425 kg for broilers at 6 weeks).
- Cost per egg (breakeven): (monthly costs + chick cost ÷ 12) ÷ monthly eggs — the one-off chick cost is spread over 12 laying months.
- Cost per kg (breakeven): total cycle cost ÷ total meat.
Worked examples
1,000 layers at Tk 58/kg feed, Tk 10.5 an egg, Tk 60 a chick, 5% mortality: Daily feed is 1,000 × 112 g = 112 kg; 3,360 kg a month (about 67 bags), costing Tk 194,880. Eggs: 950 × 94% = 893 a day, 26,790 a month, worth Tk 281,295. After Tk 10,000 of other costs the monthly profit is Tk 76,415. The Tk 60,000 chick bill is recovered in about 24 days, and each egg costs Tk 7.83 to produce.
100 broilers at Tk 74.5/kg feed, Tk 190/kg live, Tk 55 a chick: One 32-day cycle needs 100 × 4.202 = 420.2 kg of feed, costing Tk 31,305. Meat: 95 × 2.425 = 230.4 kg, worth Tk 43,771. With Tk 5,500 for chicks and Tk 1,500 of other costs, total cost is Tk 38,305; profit is Tk 5,466, or Tk 166.27 of cost per kg.
What to know in Bangladesh
- Prices move weekly: feed, egg and live-bird prices swing with the local market. The defaults follow October 2026 market rates — always enter today’s local prices.
- No fixed chick price exists: it varies by hatchery and season, which is why you must enter it.
- 5% mortality is a planning figure: some birds die even on well-run farms; keep to the vaccination schedule, because high mortality eats profit fast.
- Sonali figures are approximate: ~85 g daily intake and FCR ~2.8 are not well measured — the planner shows a caution note.
The three birds at a glance
| Layer | Broiler | Sonali | |
|---|---|---|---|
| Feed per bird per day | 112 g | ~131 g (average) | ~85 g (estimate) |
| Planning period | 1 month | 32-day cycle | ~77-day cycle (estimate) |
| Yield | 94% eggs at peak | 2.425 kg body weight | FCR ~2.8 (low confidence) |
| Starting feed price (Tk/kg) | 58 | 74.5 | 67.5 |
| Starting sale price | Tk 10.5/egg | Tk 190/kg | Tk 320/kg |
Starting prices follow October 2026 market rates; the chick price must always be entered.
More: FCR, peak lay, cages vs floor
FCR (feed conversion ratio) is the kilos of feed needed for 1 kg of weight gain. About 1.7 is good for broilers — at 1.5 the same weight needs less feed and profit rises. Sonali’s ~2.8 means more feed per kilo of gain, but the higher per-kg price can make up for it if mortality stays under control.
A 94% peak means 100 birds lay about 94 eggs a day at their best. The rate falls with age, so the full-year average is lower — use 80–85% for conservative long-term planning.
Cages vs floor: cages need less space (0.65 sq ft each) but cost more to install; floor sheds (1.75 sq ft each) need good litter management or disease rises. Broilers are raised on floor (about 1.0 sq ft each).
Chick prices decide the cycle: at Tk 70 instead of Tk 55, 1,000 chicks cost Tk 15,000 more — a big slice of the cycle’s profit. Check 2–3 hatcheries before buying.
