Broiler FCR (Feed Conversion Ratio) Calculator
Calculate the feed conversion ratio (FCR) of a broiler flock — feed used per kg of weight gain.
FCR = feed consumed ÷ live weight gained. Lower is better — modern broilers achieve 1.5–1.7. FCR drives broiler profit because feed is ~70% of cost; a 0.1 improvement across a flock is real money. High FCR points to feed quality, disease, temperature or wastage.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Broiler FCR (Feed Conversion Ratio) Calculator
Feed conversion ratio is the master efficiency number in poultry (and pig and fish) production: how many kilograms of feed it takes to produce one kilogram of live weight. Because feed is around 70% of broiler cost, FCR is the difference between profit and loss, and a small improvement multiplied across thousands of birds is significant money. This tool computes FCR from total feed and live weight, and benchmarks it — modern broilers should hit 1.5–1.7.

Frequently asked questions
What is a good FCR for broilers?+
Modern broilers achieve an FCR of about 1.5–1.7 (1.5–1.7 kg feed per kg live weight) by market age. Above ~1.8 signals a problem — feed quality, disease, poor temperature control, or feed wastage.
How do I improve feed conversion ratio?+
Use balanced, good-quality feed; maintain correct house temperature and ventilation; keep birds healthy (FCR worsens with disease); minimise feed wastage with proper feeders; and provide clean water. Genetics and pellet quality also matter.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
