Broiler FCR Calculator
Enter your birds, average weight and total feed to get your feed conversion ratio instantly — with broiler benchmark bands so you know where you stand.
1,000 birds × 2 kg = 2,000 kg live weight from 3,400 kg of feed. Lower FCR = less feed per kg of bird.
| FCR | Broiler benchmark (guidance) |
|---|---|
| ≤ 1.5 | Excellent |
| 1.5 – 1.7 | Good |
| 1.7 – 1.9 | Average |
| > 1.9 | Room to improve |
Benchmarks are general broiler guidance and shift with breed, age and feed. Use the trend across batches, not a single number.
What is FCR — and why it decides your profit
Feed conversion ratio is how many kilograms of feed it takes to add one kilogram of live bird. Because feed is around 70% of the cost of a broiler, FCR is the number that most directly moves your margin. A flock running at 1.70 instead of 1.85 across six to eight batches a year is real money kept — and for contract growers, better FCR and livability mean a larger growing charge.
What quietly wrecks FCR
Birds only convert feed efficiently when they are comfortable. The wrong temperature for their age, high ammonia, poor ventilation, or heat stress on a summer afternoon all make birds eat less and grow slower — feed wasted you never see on the bag. That is why the farms with the best FCR are the ones that hold the shed environment steady. See how Karuturi Dynamics does this on the poultry farm monitoring page, and use our poultry THI calculator to check heat-stress risk.
FAQ
Broiler FCR — common questions
How do you calculate FCR for broilers?
FCR (feed conversion ratio) = total feed consumed (kg) ÷ total live weight produced (kg). Total live weight is the birds alive multiplied by their average body weight. For example, 3,400 kg of feed for 1,000 birds at 2.0 kg each (2,000 kg) is an FCR of 1.70.
What is a good FCR for broilers?
As general guidance, an FCR at or below 1.5 is excellent, 1.5–1.7 is good, 1.7–1.9 is average, and above 1.9 has room to improve. The right target shifts with breed, age and feed, so track the trend across batches rather than a single number.
Why does FCR matter so much?
Feed is roughly 70% of the cost of growing a broiler, so FCR is the single biggest lever on profit. Even a 0.1 improvement across a year of batches is significant money, and for contract growers a better FCR means a larger growing charge.
How can I improve my FCR?
Keep birds in their comfort zone — correct temperature for their age, good ventilation, low ammonia, clean water and minimal heat stress all keep birds eating and converting efficiently. Continuous environment monitoring catches the drift that quietly wastes feed.
