How Much Does It Cost to Run an Electric Oven?
An electric oven costs $0.30-0.80 per hour to run, using 2,000-5,000 watts. Preheating costs $0.10-0.20. Baking for an hour at 350°F typically costs $0.35-0.50. Monthly cost varies widely based on cooking frequency.
Key Takeaways
- Electric ovens draw 2,000-5,000 watts depending on size and temperature.
- Gas ovens cost roughly half as much to operate as electric.
- Toaster ovens use 1/3 to 1/2 the energy for small items.
Explanation
Electric ovens draw 2,000-5,000 watts depending on size and temperature. However, they cycle on and off to maintain temperature, so actual consumption is lower than the rated wattage suggests.
At 350°F, an oven might use 2-2.5 kWh per hour of cooking (including maintaining temp after preheating). Higher temperatures like 450°F use 3-4 kWh per hour.
Convection ovens cook faster and more evenly, reducing both time and energy. Self-cleaning cycles use significant energy—one cycle equals 3-4 hours of normal baking.
Preheating time varies by oven type and affects total energy cost. Standard electric ovens take 10-15 minutes to reach 350°F, using about 0.3-0.5 kWh during preheat alone. Skipping preheat for casseroles and roasts that cook for an hour or more saves that energy entirely with minimal effect on results.
Broiling uses the top heating element at full power, typically drawing 3,000-4,000 watts. However, broiling sessions are usually short (5-10 minutes), so total energy per use is lower than baking. A 10-minute broil session costs roughly $0.08-0.10, making it more efficient than firing up the oven for 45 minutes to achieve similar browning.
Double ovens and wall ovens have different energy profiles. A smaller upper oven cavity heats faster and uses 20-30% less energy than the full-size lower oven for small meals. If you regularly cook for one or two people, using the smaller cavity saves $3-5 per month compared to always using the large oven.
Glass and ceramic baking dishes retain heat better than metal pans, allowing you to reduce the oven temperature by 25°F while achieving the same results. Batch cooking—preparing multiple dishes during a single oven session—spreads the preheat cost across several meals and can cut per-meal oven energy costs by 40-60%.
Things to Know
- Gas ovens cost roughly half as much to operate as electric.
- Toaster ovens use 1/3 to 1/2 the energy for small items.
- Opening the oven door drops temperature 25-50°F, requiring extra energy to recover.
