The formula
- Air fryer temperature = oven temperature − 25°F (or − 15°C), rounded to the nearest 5°.
- Air fryer time = oven time × 0.8 (20% less). By food type: Most recipes × 0.8, Thin & crispy × 0.75, Vegetables × 0.75, Thick meat & roasts × 0.85, Cakes & bakes × 0.85, Frozen food × 0.8.
- Check at = oven time × 0.75, rounded down.
Worked example: 400°F − 25°F = 375°F · 25 min × 0.8 = 20 min · check at 18 min
Results above 400°F (200°C) get a warning, because many basket air fryers stop there. Method version 1.1. Why these numbers: methodology.
First, check which kind of toaster oven you have
- No fan (standard toaster oven): use the conventional rule, minus 25°F and × 0.8.
- Convection toaster oven, fan on: keep the temperature and use × 0.9. Choose “Convection / fan oven” in the calculator.
- Air fryer toaster oven: its air fry setting already works like an air fryer, so no conversion is needed between that setting and air fryer recipes.

Tips for small ovens
- Toaster ovens run hot near the elements. Use the middle rack and check early, whichever direction you convert.
- Preheat both appliances. A cold start makes both cook unevenly.
- Watch batch size. Air fryer baskets hold less than a toaster oven tray, so you may need two rounds.
Accuracy and limitations
The arithmetic is exact: the same function produces the calculator result, every chart on this site and the printable chart. The cooking result is an estimate, because the formula cannot see your appliance or your food.
- Appliances vary. Wattage, basket size and how close the element sits to the food change cooking speed. That’s why every result includes a “check at” time.
- Load matters. A full or stacked basket cooks more slowly than a single layer.
- Temperature limits. Many basket air fryers stop at 400°F (200°C). Converted settings above that are flagged.
- Poor fits for any formula: wet batters, delicate cakes, low-and-slow recipes and roasts over an hour. Use a thermometer and expect to adjust.
- Food safety comes from internal temperature, not time. Check meat, poultry, seafood and leftovers against the USDA safe minimum temperatures.

Frequently asked questions
Is a toaster oven the same as an air fryer?
No. A standard toaster oven heats with still air like a small conventional oven. An air fryer uses a strong fan, so it cooks faster and crisps more.
How do I convert a toaster oven recipe to the air fryer?
Lower the temperature by 25°F (15°C) and multiply the time by 0.8. If your toaster oven has a convection fan and the recipe used it, keep the temperature and cut the time by about 10% instead.
How do I convert an air fryer recipe to a toaster oven?
Add 25°F (15°C) and multiply the time by 1.25. Use the rack position closest to the middle and leave space between pieces.
What about an air fryer toaster oven?
Use its air fry setting like an air fryer and its bake setting like a toaster oven. Air fry settings in these combo units can run a little slower than basket models, so check at the converted time and add a few minutes if needed.
