Pizza Oven Savings Calculator

It adds ingredients to fuel. Every ingredient shows a real grocery product and its shelf price, and you pay only for the portion the recipe uses (90 g of mozzarella from a 16 oz $5.20 block ≈ $0.29). Fuel is worked out per cooking session, not per pizza: the oven is preheated once and then bakes however many pizzas you make that night, so the preheat is shared across them. Every number is editable.

Because preheating is the expensive part. An Ooni Koda 16 needs a real 30-45 minute preheat before the first pizza goes in, and that fuel is spent whether you bake one pizza or eight. Bake four instead of one and the preheat cost per pizza drops by roughly three quarters. It is the single biggest lever in the whole calculation, and it is the reason flat "cost per pizza" figures elsewhere are usually wrong.

A US large delivery pizza is 14-16 inches; a typical homemade Neapolitan is 12. A 12-inch pizza has only about 60% of the area of a 16-inch one, so comparing them directly flatters the home cook. The calculator restates the delivery price as what your pizza would have cost at that pizzeria's prices, using the area ratio, and tells you when it has done so.

Electricity rates are EIA residential ¢/kWh by state (Aug 2026). Ingredient prices are typical US single-unit grocery prices. Fuel is a real pellet-bag and propane-tank price plus each oven's own burn rate. Preheat times come from our own hands-on reviews - where a manufacturer claims 20 minutes and we measured 40, we use 40 and label it. Every figure is a starting point you can overwrite with your own receipt.

The oven price plus its starter kit - peel, cover, thermometer, first tank of gas - divided by your monthly saving, where the monthly saving is the size-matched order price minus your homemade cost, times how many pizzas you make a month. The result is shown as a range, because groceries, fuel and pizza prices all move.

Once it is hot, the rate is simply 60 divided by the oven-on minutes each pizza costs you: bake, stone recovery, and the gap while you stretch the next base. That puts most 12-inch ovens around 8 to 10 pizzas an hour and a big refractory hearth like the CBO 750 Hybrid nearer 12. From cold you get far fewer in the first hour, because the preheat eats into it: a Gozney Roccbox needs 40 to 45 minutes before the first pizza goes in, so hour one gets you two or three. Every oven also has a realistic back-to-back ceiling, after which the stone stops recovering and the bakes go slower and paler. The calculator shows all three numbers.

The calculator costs every oven we have reviewed using its own fuel, its own measured preheat and its own starter kit, then filters by whether you can cook indoors or outdoors, what fuel you want, how big your pizzas are and how many you cook back-to-back. It names three answers: the best fit, the fastest to pay for itself, and the cheapest to run. They are often three different ovens.
