Want to calculate how many pizzas to buy for your party? Cool, try this pizza calculator.

This pizza calculator will help you estimate how many pizzas you should order for your pizza party. All you need to do is select the size of the pizzas that you want to order (i.e. small, medium, large, or extra large) and make some guesses about how many people are going to want 1, 2, 3, and 4 slices each. If you're also interested in estimating the total cost of your pizza party, you have the option of entering the cost per pizza, the tax rate, and the size of the tip (if any) that you'd like to give, which will allow the calculator to figure out how much you should expect to pay.

For reference, when the pizza calculator is figuring out how many pizzas you should buy it assumes the following number of slices (these are fairly standard) per pizza:

- Small Pizza (8 - 10" diameter) = 6 slices
- Medium Pizza (12" diameter) = 8 slices
- Large Pizza (14" diameter) = 10 slices
- Extra Large Pizza (16" diameter) = 12 slices

Enjoy the pizza party!
