How to use this calculator
Start by entering your current age and the age you began eating pizza regularly. Most people start around age 4 or 5, but you can adjust this to match your own experience. The calculator uses these two numbers to determine how many years of pizza eating to include in your total.
Next, enter how many slices of pizza you eat per week on average. Think about a typical week that includes both busy and quiet stretches. If you eat more during weekends or game days, factor that into your weekly average. You can also adjust the number of slices per whole pizza, since some styles are cut into 8 slices while others are cut into 10 or 12.
The results will show your estimated lifetime total in whole pizzas and slices, along with calorie and spending estimates. The fun comparisons section puts your numbers into context by converting them into stacked pizza heights, football field lengths, and other surprising visualizations.

Pizza is one of the most popular foods in the United States, with Americans consuming roughly 3 billion pies every year. That works out to about 100 acres of pizza eaten every single day across the country. The pizza industry generates over $46 billion in annual revenue, making it one of the largest segments of the restaurant business.
Saturday night is the most popular time to order pizza, followed closely by Friday evening and Super Bowl Sunday. In fact, Super Bowl Sunday is the single biggest pizza delivery day of the year, with major chains reporting delivery volumes that are two to three times higher than a normal Sunday.
The average American will eat about 6,000 slices of pizza over the course of a lifetime. Pepperoni remains the most popular topping by a wide margin, appearing on roughly 36% of all pies sold. Sausage, mushrooms, and plain cheese round out the top four, while anchovies consistently rank as the least popular topping in national surveys.
