Raw Food/BARF Calculator
Calculate raw feeding portions across muscle meat, bone and organ ratios.
About Raw Food/BARF Calculator
The ratio is normalised so the components always sum to the daily total even if the percentages entered do not add to 100. Half the organ portion should typically be liver. Bone provides calcium and organs provide vitamins that muscle meat lacks entirely, so the ratio is a nutritional requirement rather than a preference.
Formula
Raw Food/BARF
Daily total = body weight × feeding rate; components split by the chosen ratio
- 80/10/10
- The common prey model ratio of muscle, bone and organ
- feeding rate
- About 2 to 3 per cent of body weight for adult maintenance
Worked example

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Raw feeding carries risks including bacterial contamination and nutritional imbalance, and is not suitable for every animal or household. Consult a veterinarian or veterinary nutritionist before starting, and follow safe food handling practice.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
How is Raw Food/BARF calculated?
Daily total = body weight × feeding rate; components split by the chosen ratio The ratio is normalised so the components always sum to the daily total even if the percentages entered do not add to 100. Half the organ portion should typically be liver.
Why does Raw Food/BARF matter?
Bone provides calcium and organs provide vitamins that muscle meat lacks entirely, so the ratio is a nutritional requirement rather than a preference.
What values do I need to enter?
This calculator takes 5 inputs: Body weight, Daily feed as a share of body weight, Muscle meat share, Raw edible bone share, Organ share. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
