Animals Spared Calculator
Most people never see the arithmetic behind a shopping basket. Enter what you eat in a typical week and this tool converts servings into an estimated number of individual animals per year, using published carcass and yield figures. Reduce any input to see how many animals that change would spare.
Short answer: A typical omnivorous diet in a high-income country involves roughly 25 to 30 land animals a year — the overwhelming majority of them chickens — plus a larger and less certain number of fish.

How this is calculated
- One serving is treated as 125 g of cooked meat or fish.
- Edible yield per animal: broiler chicken about 1.5 kg, pig about 70 kg, cattle about 200 kg, farmed fish about 0.4 kg.
- A laying hen produces roughly 300 eggs a year; a dairy cow produces roughly 8,000 litres of milk a year.
- Results are estimates of animals involved, not a precise count, and exclude wild-caught bycatch and animals killed on farms before slaughter.
Frequently asked
- How many animals does one person eat per year?
- In high-income countries the typical figure is around 25 to 30 land animals a year, dominated by chickens because each bird yields only a few kilograms of meat.
- How many animals does going vegan save?
- Removing all animal products removes those 25 to 30 land animals a year plus the fish involved, and ends the demand share for the laying hens and dairy cows behind eggs and milk.
- Why do chickens dominate the count?
- Because body size drives the arithmetic. One steer supplies well over a thousand servings; one chicken supplies about a dozen, so chicken-heavy diets involve many more individuals.
