Air Fryer vs Oven: Which Costs Less to Run in Australia? (We Did the Maths)
When it comes to cooking at home, Australians are increasingly asking: "Which is cheaper to run—an air fryer or a conventional oven?" With electricity prices fluctuating and energy efficiency becoming more important, understanding the cost implications of your kitchen appliances is crucial. In this in-depth guide, we crunch the numbers to help you decide which method saves you more money, without sacrificing taste or convenience.
Quick Answer / TL;DR Air fryers generally cost less to run than traditional ovens for small to medium-sized cooking tasks due to their faster preheat times and smaller cooking chambers. However, for large meals or batch cooking, a conventional oven may be more cost-effective per kilogram of food. In Australia, average electricity costs and appliance wattages mean that an air fryer can save you around 20-40% on energy for typical daily use.
Understanding Energy Consumption: Air Fryer vs Oven
How Air Fryers Use Electricity Air fryers are compact countertop appliances that circulate hot air rapidly to cook food, mimicking the effect of deep frying but with little to no oil. Typical power ratings for air fryers range between 1400W and 1800W, depending on the model and size. For example, the budget-friendly [Healthy Choice 3L Digital](https://airfryerhub.vip/reviews/healthy-choice-3l-digital) runs at around 1500W, while the larger [Ninja Pro XL 6.2L AF181ANZ](https://airfryerhub.vip/reviews/ninja-pro-xl-6-2l) consumes closer to 1750W.

Because their cooking chambers are smaller, air fryers heat up quickly, usually needing just 2-3 minutes to preheat before you start cooking.
How Ovens Use Electricity Traditional electric ovens in Australian homes commonly have power ratings between 2000W and 3500W. They have much larger internal volumes (typically 60-70 litres), which means they take longer to preheat—usually 10-15 minutes—and consume more energy maintaining those temperatures.
For instance, the Sunbeam Multi Zone Oven is a popular oven-style appliance with multiple cooking zones, consuming about 2000W but with a larger capacity.
Key Differences in Energy Use - **Preheat time:** Air fryers need only a few minutes vs ovens taking 10-15 minutes - **Cooking chamber size:** Air fryers have smaller chambers, meaning less air to heat - **Wattage:** Ovens generally have higher wattage and use more energy over time
Running Costs Breakdown for Australian Households
Calculating Running Costs Electricity in Australia is typically charged per kilowatt-hour (kWh). As of mid-2024, the average residential electricity cost is about 30c to 35c per kWh, depending on your state and provider.
Formula:
Running Cost = (Wattage ÷ 1000) × Cooking Time (hours) × Cost per kWh
Example: Air Fryer Cost per Use Let’s calculate the cost of air frying chips at 180°C (356°F) for 20 minutes in a 1500W air fryer:
- Power: 1.5 kW
- Time: 20 minutes = 0.33 hours
- Cost per kWh: $0.33
Cost = 1.5 × 0.33 × 0.33 = $0.16 per cooking session
Example: Oven Cost per Use Cooking the same chips in an electric oven at 180°C (356°F) for 20 minutes + 10 minutes preheat (total 30 minutes = 0.5 hours) at 2500W:
Cost = 2.5 × 0.5 × 0.33 = $0.41 per cooking session
This shows an air fryer can cost less than half the electricity of a traditional oven for the same cooking task.
Capacity and Cooking Efficiency: What Size Do You Need?
Air Fryer Capacities Air fryers come in various sizes, from compact 3L models to large 10.4L units:
- Healthy Choice 3L Digital (3 litres) — great for singles or couples
- Philips 2000 Series 4.2L — excellent mid-size
- Ninja FlexDrawer 10.4L AF500ANZ — family-sized capacity
Philips 2000 Series Airfryer 4.2L
Best value for couples under A$110
- ✓Philips RapidAir Technology for even cooking
- ✓13-in-1 cooking functions
Choosing the right size affects energy use; cooking small amounts in a large air fryer wastes energy heating unused space.
Oven Capacities Standard Australian ovens often have 60-70L capacity, much larger than air fryers. They are ideal for batch cooking or multiple dishes but less efficient for small meals.
Cooking Efficiency Air fryers’ rapid hot air circulation means food cooks faster and often more evenly, reducing cooking time and energy consumption.
Comparing Cooking Times and Versatility
Cooking Speed Air fryers usually reduce cooking time by 20-30% compared to ovens due to faster heat transfer and smaller size.
Multi-Functionality Ovens can handle a wider variety of dishes, including large roasts and baking multiple trays at once, whereas air fryers excel at roasting, baking, grilling, and reheating smaller portions.

Environmental Impact: Which is Greener?
Energy Consumption Lower energy consumption means less carbon footprint. Air fryers’ shorter cooking times generally translate to lower emissions.
Materials and Longevity Ovens tend to be more durable with longer lifespans, whereas some budget air fryers might need replacing sooner.
Common Mistakes to Avoid
- Overestimating air fryer capacity: Buying a large air fryer for single use leads to wasted energy.
- Ignoring preheat times: Not considering preheating can skew running cost calculations.
- Cooking too large meals in air fryers: Overcrowding reduces efficiency and increases cooking time.
- Not using the right temperature: Cooking at excessively high temperatures wastes energy.
- Neglecting appliance maintenance: Dirty ovens or air fryers consume more power.
- Comparing different cooking tasks: Always compare similar cooking methods for accurate cost assessment.
