How to calculate the calories in a slice of pizza?

Calorie per slice of pizza = tc / s


  • tc = total calories in the pizza
  • s = number of slices that the pizza is cut into

How to use the Pizza Calculator

The pizza calculator is a good calculator for working out how many slices to cut a pizza into as part of a calorie-controlled diet. Pizza is typically high in calories as it is packed with delicious, rich toppings. The fact that pizzas taste so great often means it is easy to eat a higher portion size (from a calorie perspective) than you would do of other food types. The pizza calculator is designed to allow you to manage those portions to suit your calorific needs by identifying the calorie per slice.

The pizza calculator works in 3 unique ways:

  1. Pre-made Pizza Calculator for pre-made pizzas (typically used for supermarket pizza)
  2. Takeaway pizza which calculate the calories per slice of pizza based on pizzas purchased from Domino's pizza
  3. Homemade pizza calculator for pizzas that you make yourself

Lets take a look at each of these three features and explore how to calculate the calorie per slice of pizza using each method:

Takeaway Pizza Calculator

We decided to use Domino's pizza for the standard dropdown calculation of calories per slice of pizza calculation as Domino's is a worldwide brand and popular pizza company, the chances are that there is a Domino's near you and you have most likely eaten there. Domino's are also very transparent about the calorific values within the foods they sell. This, combined with the fact we believe Domino's provide the best takeaway pizzas, meant that it was a logical choice for predefined pizza calculations.

  2. Enter the number of slices the pizza is cut into (or your own number of slices if you will cut the pizza yourself)
  3. Select the type of pizza you have ordered

Please note that for the calculation of calories per pizza for Dominos pizza we have used a classic crust and factored the 3 portion size calorie count1 into an 8 slice pizza1. We have provided a formula for this calculation, the pizza formula is displayed above the table "Domino's pizzas - Calories per Pizza".
