Feed Conversion Ratio Calculator

Find how efficiently animals convert feed to weight.

Feed consumed

Weight gained

Feed conversion ratio 2.5

Formula: FCR = feed ÷ weight gain

Step-by-step with your numbers:

1. Values used:

2. Feed consumed = 500

3. Weight gained = 200

5. Feed conversion ratio = Feed consumed / Weight gained = 500 / 200 = 2.5

Did we solve your problem today?

FCR shows how many pounds of feed produce one pound of growth — lower is more efficient.

The math behind it

FCR = feed consumed ÷ weight gained.

500 lb feed for 200 lb gain → FCR 2.5.

Typical values?

Broilers ~1.6, pigs ~3, cattle ~6 — species differ a lot.
