Air Fryer Calculator
Convert standard oven temperatures and times to air fryer settings. Use our free tool to get perfectly cooked food every time.
Introduction
Air fryers cook food significantly faster and more efficiently than conventional ovens because they use powerful fans to circulate hot air in a small space. Our Air Fryer Calculator takes the guesswork out of cooking by converting any traditional oven-based recipe for your air fryer.
How to Use
To use the calculator, simply enter the recommended oven temperature and the cooking time from your original recipe. Select whether your temperature is in Celsius or Fahrenheit. The tool will provide the adjusted air fryer temperature and time.
Formula
The standard "25/20 Rule" is used: Reduce the oven temperature by 25°F (15°C) and reduce the total cooking time by 20%.
Examples
Example: If a recipe calls for 400°F for 20 minutes, your air fryer should be set to 375°F for 16 minutes.
Results Explained
The results show the estimated temperature and time for your air fryer. Because air fryer models vary in power and size, we always recommend checking your food a few minutes before the timer ends.

The Magic of Air Frying
An air fryer is essentially a high-powered countertop convection oven. Its small size and powerful fan allow for rapid heat transfer, which creates a crispy "fried" texture with very little oil. However, because they are so efficient, you cannot simply use the same time and temperature as a traditional large oven without burning your food.
Why You Need to Convert Recipes
Standard recipes are designed for conventional ovens, which take longer to heat up and have "dead zones" where air doesn't move. In an air fryer, the heat is intense and constant. If you use the original recipe settings, your food will likely be burnt on the outside and undercooked on the inside.
The 25/20 Rule Explained
Most professional chefs and air fryer enthusiasts follow the 25/20 Rule for conversion:
- Temperature: Lower the temperature by 25°F (about 15°C). This prevents the exterior from crisping too fast.
- Time: Reduce the cooking time by 20%. Since the air is moving so fast, the food cooks much quicker than in still air.
Top Tips for Perfect Air Frying
To get the most out of your air fryer and our calculator, keep these tips in mind:
- Don't Overcrowd: Air needs to circulate to make food crispy. If you stack food, it will steam instead of fry. Cook in batches if necessary.
- Shake the Basket: For items like fries or wings, shake the basket halfway through to ensure even browning.
- Use a Spritz of Oil: While you don't need to submerge food in oil, a light spray of olive or avocado oil can significantly improve the "crunch."
- Preheat: Just like an oven, most air fryers work best when they are already hot when the food goes in.
Safety and Maintenance
Always place your air fryer on a heat-resistant surface and ensure there is enough space behind the unit for the exhaust fan to blow out hot air. Regular cleaning of the basket and the heating element will prevent smoke and keep your food tasting fresh.
Frequently Asked Questions
Do all air fryers cook at the same speed?
No, different brands and sizes (basket vs. oven style) have varying levels of power. Use our calculator as a starting point and adjust based on your specific model.
Can I put aluminum foil in an air fryer?
Yes, but don't cover the entire bottom of the basket, as it blocks the airflow. Also, never put foil in without food on top, or it will fly into the heating element.
Why is my air fryer smoking?
This is usually caused by grease splashing onto the heating element or by cooking at too high a temperature. Cleaning the unit regularly prevents this.
Do I need to preheat my air fryer?
Most models benefit from 3-5 minutes of preheating, though some modern ones claim it isn't necessary. It generally leads to crispier results.
Can I cook frozen food in an air fryer?
Absolutely! The air fryer is the best way to cook frozen snacks. You usually don't need to adjust the temperature for frozen items, just the time.
How do I clean an air fryer?
Most baskets are dishwasher safe. For the main unit, wait for it to cool and wipe the inside with a damp cloth and mild soap.
