Numbers Explained: 

Various methods exist to calculate the number of animals saved by adopting a vegan lifestyle. The rationale behind some of these calculations is more sound than others, and the reliability of the data sources used in these calculations also varies.


In our approach, we've aimed to tackle both concerns:

- We source our data from widely recognized and reputable organizations such as the USDA, European Commission, OECD, and others, ensuring the information we use is reliable.

- The question of whether abstaining from consuming a single meat pasty directly translates to saving one animal's life is more nuanced than it appears. Our calculations focus on the precise inquiry: "How many animals have I not consumed since going vegan?" We believe this method provides the most accurate estimate of the number of animal lives saved through adopting a vegan lifestyle.

Hence, "Animals Saved" = "Not eaten the equivalent weight of those animals, and not eaten the equivalent number of Cows/Hens required to produce the average consumption of dairy and eggs"

The method focusing on "How many animals have I not consumed since going vegan?" is highly effective for several reasons, making it arguably the best approach to measure the impact of adopting a vegan lifestyle on animal lives saved:

1. **Concrete Impact Measurement**: This approach quantifies the direct impact of dietary changes by calculating the exact number of animals not consumed as a result of one's diet shift. It offers a tangible measure of one’s personal contribution to reducing animal consumption.

2. **Personal Accountability and Awareness**: Focusing on individual consumption highlights personal responsibility and raises awareness about the implications of dietary choices. It encourages individuals to reflect on the direct relationship between their actions and their impact on animal welfare.

3. **Simplicity and Relatability**: The concept of counting animals not consumed is straightforward and easy for people to understand and relate to. This relatability can motivate more people to consider the effects of their dietary choices and potentially adopt a vegan lifestyle.

4. **Data-Driven Approach**: By basing the calculation on the average amounts of animal products typically consumed, this method leverages existing data (such as national averages) to provide an estimate that's grounded in reality. This helps in creating a more accurate and reliable estimate of the impact of going vegan.

5. **Encourages a Holistic View of Veganism**: This calculation methodology inherently acknowledges that veganism is not just about avoiding meat but also about rejecting all forms of animal exploitation and consumption, including dairy and eggs. It embodies a comprehensive view of what it means to save animal lives through dietary choices.

6. **Promotes Veganism's Cumulative Effect**: By calculating the animals not consumed over time, it underscores the cumulative effect of being vegan. This can be very empowering, showing that even a single person's dietary choices can save hundreds of animals over years.

7. **Adaptable to Individual Lifestyles**: This method allows for adjustments based on personal consumption patterns before going vegan, providing a tailored estimate that can accurately reflect an individual's impact on reducing animal suffering and death.

In summary, this calculation method effectively communicates the significance of individual choices in promoting animal welfare. It empowers individuals by providing a clear and impactful visualization of how a vegan lifestyle directly contributes to saving animal lives.


Meat: If one person, on average, eats 1 KG of "Animal A" flesh per year and "Animal A" produces "usable" flesh of 3 KGs per animal. Then that person saves 1 x "Animal A" every 3 years.  

Dairy: If one person, on average, consumes 1 Litre of dairy products, consumed as milk, cheese, yoghurt etc per annum and "Milking Animal A" produce 5 Litres of dairy per annum. Then that person saves 1 x "Milking Animal A" every 5 years.

Eggs: If one person, on average, consumes 100 Eggs, consumed as Eggs or Egg products per annum and "Egg Laying Animal A" produce 250 Eggs per annum. Then that person saves 1 x "Egg Laying Animal A" every 2.5 years.

How the Calculation Works

The calculation process "Animals Saved Calculator" is centred around estimating the number of animals a person has potentially saved by adopting a vegan diet for a certain period. The calculation follows several steps, and each plays a crucial part in arriving at the final numbers. Here is the break down to the final calculation:

1. Capture User Inputs

- **Start Date**: The date when the user started went Vegan. This is crucial for calculating how long the user has been vegan.
- **Region**: The user’s region (e.g., "USA" or "EU"). This is important because animal consumption rates can vary significantly by region, affecting the calculation.

2. Calculate the Number of Days Vegan

This step is vital as it determines the duration since the start date up to the current date, calculated in days. 

The calculation compares todays date, and the "Vegan Start Date" that was entered. The difference between these dates gives us the number of days Vegan.

3. Defining and Calculating the Daily Saving Rates

Based on the selected region, the daily lives saved per animal type are calculated from:

Cows saved per annum = (The average KG of Cow flesh consumed per annum, per person / The average KG of used flesh per Cow) + (The average Litres of dairy products consumed as Milk, Cheese, Yoghurt etc per annum, per person / The average Litres of milk produced per annum, per Cow)

Chickens saved per annum = (
The average KG of Chicken flesh consumed per annum, per person / The average KG of used flesh per Chicken) + (The average number of eggs consumed as an egg or an egg product per annum, per person / The average number of eggs produced per annum, per Hen)

Pigs saved per annum =
The average KG of Pig flesh consumed per annum per person / The average KG of used flesh per Pig.

Lambs saved per annum = 
The average KG of Lambs flesh consumed per annum per person / The average KG of used flesh per Lamb.

Fish saved per annum -
The average KG of Fish flesh consumed per annum per person / The average KG of used flesh per Fish, based on an average Salmon weighing a total of 4.05 KG each.

4. Sources of Data Used

EU Sources :
 European Commission, The Organization for Economic Cooperation and Development (OECD), European Market Observatory for Fisheries and Aquaculture (EUMOFA), European Commission and Eurostat.

USA Sources : USDA, American Egg Board

5. Conclusion

The "Animals Saved Calculator" serves as a powerful tool designed to quantify the impact of adopting a vegan diet on animal welfare. By meticulously gathering crucial inputs such as the inception date of one's vegan journey and geographical region, the calculator sets the stage for an insightful exploration. It systematically computes the length of time an individual has been vegan and then delves into calculating the daily saving rates of animals based on regional consumption patterns and production statistics from official sources.

The crux of the calculation pivots on estimating the number of cows, chickens, pigs, lambs, and fish potentially 'saved' through abstaining from meat and dairy consumption. For cows and chickens, detailed formulae incorporate both meat and by-products like milk and eggs, enhancing the accuracy of the calculator. The derived saving rates for pigs, lambs, and fish further broaden the scope of the analysis. Grounding its calculations in reputable sources from both the EU and the USA, including the European Commission, USDA, and the American Egg Board, among others, the calculator ensures credibility and relevance to its findings.

In essence, the "Animals Saved Calculator" not only sheds light on the direct connection between dietary choices and animal welfare but also emphasizes the significance of individual contributions towards a more humane and sustainable world.
