How to use
How to Use This Air Fryer Calculator
Converting oven recipes for your air fryer takes only a few seconds with this free air fryer calculator. Follow these simple steps:
- Enter your oven temperature. Type the temperature from your original recipe. Use the °F / °C toggle to switch units — the calculator converts automatically.
- Enter your oven cooking time. Input the total cook time in minutes (between 1 and 240).
- Select a food type. Choosing the correct category applies small preset modifiers for better accuracy. Baked goods benefit from a slightly lower temperature, while frozen foods need a touch more time.
- Set your basket load. If your air fryer basket is packed tightly, choose “Crowded” — the calculator adds extra time to compensate for restricted airflow.
- Choose your doneness. Prefer a softer result? Select “Less Crisp.” Want that signature golden crunch? Go with “Extra Crisp.”
- Read your results. The recommended air fryer temperature and cooking time appear instantly. A personalised tip appears based on your selections.
- Copy or reset. Hit “Copy Result” to save your settings to clipboard, or “Reset” to start fresh with defaults.
The science
Why Convert Oven Recipes for Your Air Fryer?
Air fryers work a lot like small convection ovens, but there’s one big difference: the heating element and fan sit much closer to your food, and the inside is much smaller. That means hot air moves around your food quickly and intensely, so if you use regular oven cooking times, things usually end up overcooked or dried out.
The standard oven to air fryer conversion rule is:
- Reduce temperature by 25°F (15°C)
- Reduce cooking time by 20%
These numbers reflect how convection works: because air is constantly moving quickly around your food, it heats it much more efficiently than a regular oven does. That’s also why you get crispy, browned food faster and at lower temperatures — thanks to something called the Maillard reaction.
No matter what brand of air fryer you have, whether it’s Ninja, Cosori, Philips, Instant Vortex, or something else. But the core air fryer temperature conversion stays the same. This calculator will work for any brand or basket size.

Air Fryer Cooking Times & Temperatures for Common Foods
The table below shows typical air fryer cooking times and temperatures for popular foods, assuming a preheated air fryer and a single-layer basket. Use these as a starting reference and adjust based on your specific model and food thickness.
Frequently Asked Questions
How much do I reduce the temperature when using an air fryer?
The simple rule of thumb: lower the oven temperature by 25°F (about 15°C) when using an air fryer. For example, if a recipe says 400°F in the oven, set your air fryer to around 375°F instead. That’s because air fryers heat food more efficiently. If you’re making baked goods, drop the temperature by another 10°F to keep things from getting too brown.
How much do I reduce the cooking time?
Start by cutting the cooking time by 20%. So if a recipe says 30 minutes in the oven, set your air fryer for about 24 minutes. Check your food a few minutes early, since air fryers all work a little differently. It’s a lot easier to add a bit more time than to fix food that’s already overcooked.
Does this air fryer calculator work for frozen foods?
Yes. When you select “Frozen Foods” in the food type dropdown, the calculator adds a couple of minutes to account for the extra energy needed to thaw and cook from frozen. Frozen foods often need a slightly longer cook time compared to fresh equivalents, even in an air fryer. Always shake the basket partway through for even cooking.
Is this calculator compatible with Ninja, Cosori, Philips, and other brands?
Yes — the Ninja air fryer calculator conversion rules and the Cosori air fryer conversion rules are based on the same underlying physics of convection cooking. Reduce temperature by 25°F and time by 20%, and you’ll get reliable results across virtually all major brands. Slight adjustments may be needed based on your specific model’s wattage and basket size.
Should I preheat my air fryer?
Most air fryer manufacturers recommend a 3–5 minute preheat at the target cooking temperature. Preheating helps the food start cooking immediately upon entering the basket, contributing to better browning and crispiness. If you skip preheating, add 2–3 minutes to the calculated time. This air fryer cooking time calculator assumes a preheated appliance.
Why does basket load affect cooking time?
Air fryers work by circulating hot air around the food. When you fill the basket to capacity or pile food in multiple layers, airflow is restricted — hot air can’t reach all surfaces evenly. This leads to uneven cooking and longer times to achieve the same result. The calculator adds 10% to the cooking time when “Crowded” is selected. For best results, cook in single layers whenever possible.
Are the results from this air fryer conversion calculator exact?
The results are reliable starting estimates, not guarantees. Variables like your specific model’s wattage, food thickness, moisture content, and starting temperature all affect actual cook times. Use the calculator’s output as a starting point, then verify with a food thermometer for meats and check visually for baked goods and vegetables.
Air Fryer Tips for Best Results
- Don’t skip the shake. For smaller items like fries, nuggets, or veggies, shaking the basket or flipping food halfway through dramatically improves browning.
- Pat foods dry. Excess moisture creates steam rather than crispness. Pat proteins and vegetables dry with paper towels before cooking.
- Use a light coat of oil. A spray or brush of oil on the food (not the basket) promotes browning and prevents sticking.
- Don’t overcrowd. Cook in batches if needed. A second batch takes only minutes and the result is far better than a crowded basket.
- Check early. The single most common air fryer mistake is following oven timings exactly. Always check 3–5 minutes before your calculated finish time.
- Adjust for altitude. If you’re at high elevation, cooking times may need to increase slightly due to lower air pressure.
- Use parchment liners carefully. Perforated parchment liners made for air fryers are helpful for delicate foods. Never block the bottom holes — airflow must remain unrestricted.
