Free Air Fryer Baking Tools
Four calculators for the questions that come up every time you bring an oven recipe to a basket: what temperature, what pan, how much, and what it costs to run. All free, all in your browser, nothing stored anywhere.
Air Fryer Calculator
Turn any oven recipe into the right basket setting. It adjusts for what you are cooking and the model on your counter rather than applying a flat rule, and it converts back to oven settings too.
- Conventional and fan ovens, °F, °C and UK gas marks
- Adjusts by food type and by air fryer model
- Reverse mode: air fryer back to oven
Pan Size Calculator
Quarts on the box tell you nothing about what fits. Measure the flat floor of your basket and this gives you the largest pan that still leaves room for air to move.
- Largest round, square and loaf tin that fits
- Builds in a half inch airflow gap and headroom
- Second tab converts a recipe between pan sizes
Recipe Scaler
Paste an ingredient list and get it halved, doubled or scaled to any factor, in fractions you can actually measure with cups and spoons.
- Solves partial eggs by weight, not by guessing
- Trims leavening and salt, which do not scale straight
- Tells you what the new batter depth does to the bake
Air Fryer vs Oven Cost Calculator
What one bake actually costs to run, using your own wattage and the unit rate off your bill rather than a national average.
- Realistic duty cycles, not raw wattage
- Seven currencies, plus gas and fan ovens
- Honest about when the oven is cheaper
Pick one
Which tool do you need?
Most people arrive with one of four problems. This is the shortest route from each of them to an answer.
| What you are trying to do | Use |
|---|---|
| “This recipe says 350°F for 40 minutes in the oven” | Air Fryer Calculator |
| “Will my cake tin even go in the basket?” | Pan Size Calculator |
| “I need half of this, and it has three eggs” | Recipe Scaler |
| “Is the air fryer actually cheaper than the oven?” | Cost Calculator |
| “What temperature does this specific bake want?” | Air fryer baking chart |
In order
How the four fit together
Adapting an oven recipe properly means four decisions, and they have to happen in this order, because each one changes the next.
Skipping step one is the usual mistake. People convert the temperature perfectly, then pour the batter into a much smaller tin and wonder why the middle is raw. Two separate corrections are needed and most guides only mention one, which is covered in more depth in our guide to converting oven recipes for an air fryer.

Beyond the tools
Guides that go with them
The calculators give you a number. These explain why the number is what it is, which is what stops the next bake going wrong.
| Guide | Answers |
|---|---|
| How to bake in an air fryer | The whole method, start to finish |
| Basket vs oven-style | Which machine suits which bake |
| Do you need to preheat? | Which bakes care, and which do not |
| Avoiding dry bakes | Why air fryers dry things out, and the fix |
| Getting things crisp | Why surface water caps browning |
| Troubleshooting | Raw middles, burnt tops, sunken cakes |
Every setting in these tools traces back to a recipe that was baked and re-baked in a real basket. You can see the whole library on the recipes page, or start from the baking chart if you want times and temperatures at a glance.
Questions
About these tools
QAre these air fryer tools free?
Yes, all four are free and there is nothing to sign up for. They run entirely in your browser, so nothing you type is sent anywhere or stored on a server. You can use them on a phone, and the print button on each one gives you a clean sheet to keep next to the machine.
QWhich tool should I start with?
If you are adapting an oven recipe, start with the pan size calculator to find out what you can actually bake in, then the recipe scaler to get the quantities for that pan, then the main calculator for the temperature and time. Pan first, because the pan decides the batter depth and the depth decides the bake time.
QDo I need to know my air fryer's wattage?
Only for the cost calculator. It is printed on the rating plate underneath the machine rather than on the box, and it is usually between 800 and 1800 watts. The other three tools do not need it. The pan size calculator wants your basket measurements instead, and you get those with a ruler in about two minutes.
QWill these work for cooking as well as baking?
The main calculator and the cost calculator work for any food. The pan size calculator and the recipe scaler are built around baking, since they deal with tins and batter, but the scaler will happily scale any ingredient list and the pan tool works for anything you put in a dish.
QHow accurate are the numbers?
They are good starting points rather than guarantees, and every tool says where its limits are. The settings behind the main calculator come from recipes tested in a standard basket. The cost calculator uses typical appliance duty cycles, so your own wattage and unit rate matter more than any assumption in the model. The pan tool builds in a real airflow gap, which is why it calls some pans tight even when they physically fit.
QCan I use them on my phone?
Yes. All four are built to work on a phone screen, with the inputs stacking into a single column and the results staying readable. Each one has a copy button that puts the result on your clipboard, which is the quickest way to get a setting into your notes or a message.
