Air Fryer vs Oven – Which Saves You More Money?
The real cost of cooking your dinner (and how to cut it without cutting corners)
With energy prices still a hot topic, more households are asking a simple question:
👉 Is the air fryer actually cheaper than the oven?
The short answer? Yes—most of the time.
But the full story is a bit more interesting (and more useful).
Here’s everything you need to know to make the smartest, money-saving choice in your kitchen.
It All Comes Down to Two Things
When it comes to cost, only two factors really matter:
- Power usage (watts)
- How long you’re cooking
Air Fryer
- Uses around 1,200–2,000 watts
- Heats up almost instantly
- Cooks faster thanks to its compact size
Oven
- Uses around 2,000–5,000 watts
- Needs 10–15 minutes preheating
- Takes longer to cook most foods
👉 So right away, the air fryer has a double advantage: less power + less time.
Real-Life Cost Comparison
Let’s make it practical. Based on an estimated electricity rate of €0.40 per kWh:
Chips (Family Portion)
| Method | Time | Estimated Cost |
| Air Fryer | 18–22 mins | €0.20–€0.25 |
| Oven | 35–45 mins | €0.65–€0.75 |
👉 Up to 3x cheaper in the air fryer
Chicken Fillets
| Method | Time | Estimated Cost |
| Air Fryer | 18–22 mins | €0.20–€0.30 |
| Oven | 30–40 mins | €0.60–€0.80 |

The Part Most People Miss
It’s not just about wattage—it’s about efficiency.
An oven heats a large space (most of which you’re not even using), while an air fryer focuses heat directly on your food.
💡 It’s like boiling a kettle vs heating a full tank of water—you only use what you need.
When the Oven Still Makes Sense
The oven isn’t obsolete—far from it.
Use your oven when:
- Cooking for 4+ people
- Preparing multiple items at once
- Baking (cakes, breads, roasts)
- Doing a big Sunday dinner
👉 If you’re filling the oven properly, it becomes much more cost-efficient.
Hidden Savings That Add Up
Faster Cooking = Lower Bills
Shorter cooking times mean less electricity used overall.
Less Heat in the House
Air fryers don’t heat the whole kitchen—ideal during warmer months.
Quicker Clean-Up
Less mess, less hot water, less hassle.
The Tommie Kelly Approach
At Tommie Kelly, we’re big believers in practical savings that actually work in real homes.
The smartest strategy isn’t choosing one appliance—it’s using both wisely:
✔ Air fryer for everyday meals (quick, cheap, efficient)
✔ Oven for bigger jobs (batch cooking, family meals)
👉 That’s how you keep costs down without sacrificing convenience.
Final Verdict
💡 If you’re using your oven for small portions, you’re likely spending more than you need to.
