FCR calculator — what each point of feed conversion is worth.
Turn feed conversion ratio into cash. Enter flock size, live weight, FCR and feed price to get total feed, feed cost per kg live weight, and the annual value of a 0.05 FCR improvement — then compare FCR 1.8, 1.7, 1.6 and 1.5 side by side.

Effective FCR
1.65
Your input adjusted by scenario. A breeder guide FCR is a target under guide conditions, not a contractual outcome.
Live weight produced
69,120 kg
28,800 birds sold × 2.4 kg average live weight.
Total feed
115.9 t
Includes feed eaten by mortality at 40% of a full cycle's intake.
Cycle feed cost
$49k
At $420/t delivered.
Feed cost per kg live
$0.705
The number to compare between houses, cycles and suppliers — it normalises out flock size.
Saving per 0.05 FCR gained
$1,476 / cycle
Roughly $10,330 per year at 7 cycles. Equipment that improves feed distribution, water quality or house climate is judged against this number.
FCR ladder
1.8 → 1.5
FCR 1.80: $0.769/kg live (cycle feed $53k) · FCR 1.70: $0.726/kg live (cycle feed $50k) · FCR 1.60: $0.683/kg live (cycle feed $47k) · FCR 1.50: $0.640/kg live (cycle feed $44k)
Feed conversion ratio is kilograms of feed consumed per kilogram of live weight produced. An FCR of 1.65 means 1.65 kg of feed produced 1 kg of live bird. Lower is better. Compare only like-for-like: at the same average weight, same age and the same feed-inclusion basis (as-fed, not dry matter).
On a 30,000-bird house finishing at 2.4 kg with feed at $420/t, 0.05 FCR is roughly $1,500 per cycle, or around $10,500 a year at seven cycles. That figure — not the equipment price — is the correct yardstick for feeder, drinker and climate-control upgrades.
Use actual FCR for cash decisions and weight-corrected FCR for benchmarking between flocks harvested at different weights. This calculator works on actual as-fed FCR at the average live weight you enter.
Birds that die still ate. The model charges mortality with 40% of a full cycle's intake, because deaths cluster in the first week and again near the end. Ignoring that understates feed by 1–3% on a typical flock.
Do not ask suppliers to guarantee FCR — no equipment vendor controls genetics, feed quality or management. Instead specify the things they do control: feed-pan distribution uniformity, water line pressure regulation, house temperature and static-pressure control accuracy, and downtime response.
