Groupon finds that Little Caesars offered the best savings in pizza.

## Groupon Calculates Pi to Find Cost Savings in Large Pizzas

#### The cost-savings app uncovers the surprisingly high price of small pizzas.

Bigger is sometimes better.  Groupon, an online app that connects subscribers to discounts from merchants, warns against buying small pizzas.

Groupon spent a month compiling data on 230 individual pies at Domino’s, Pizza Hut, Casey’s, Papa Murphy’s, and Little Casesars.  They calculated the surface area and calories per pizza, and found that the surface area is more important than the standard diameter of pizza measurement.

Calculating from plain, specialty, and one-topping pizza, the app found that a 10-inch pizza is nearly two times more expensive than a 16-inch pizza.  Two or three slices of a 14-inch pizza will cost \$5 per slice, but will cost \$8 per slice in a 10-inch pizza.

Little Caesars will save the most money since it offers only one size: 14-inch, with the lowest price per person at \$2.30.

Papa John’s also has the steepest drop in cost per slice from its smallest to largest pie: \$8.70 per person for a small to \$5.83 for an extra large per person.

Groupon's math shakes out to this: a 16-inch pizza has the same amount of area as roughly two-and-a-half 10-inch pizza. So to buy the equivalent of a 16-inch pizza in 10-inch pizzas, the customer would have to spend \$32.76 instead of \$19.23 they could’ve spent instead on the 16-inch pizza.

There will always be customers that love the small pies, but for those throwing pizza parties or feeding a family… size up.
