How Much Does It Cost to Run an Electric Oven?
Calculate electric oven and cooktop power draw (2,000W–5,000W), thermostat duty cycle, preheat consumption, and hourly cooking costs.
Key Takeaways & Core Facts
- Electric ovens draw 2,000 to 5,000 Watts when elements are active, consuming 1.5 to 3.0 kWh per hour of baking.
- Because the thermostat cycles heating elements on and off (50% to 60% duty cycle), average power draw is less than maximum rated wattage.
- Preheating an oven to 350°F consumes approximately 0.5 to 0.8 kWh before cooking begins.
- Baking for 1 hour costs $0.23 to $0.90 depending on element wattage, thermostat duty cycle, and local electricity rates (15¢ to 30¢ per kWh).
Direct Answer: Electric Oven Power Draw & Cost
An electric oven draws 2,000 to 5,000 Watts when heating elements are active. However, because internal thermostats cycle elements on and off (duty cycle of 50% to 60%), baking at 350°F consumes approximately 1.5 to 2.4 kWh per hour.
At a 20 ¢/kWh electricity rate, running an electric oven for 1 hour costs approximately $0.30 to $0.48 per hour.
Electric Oven Thermostat Duty Cycle Formula
For a 3,000 Watt (3.0 kW) oven operating at 55% thermostat duty cycle: 3.0 kW × 0.55 = 1.65 kWh per hour. At 20 ¢/kWh, cost = 1.65 kWh × $0.20 = $0.33 per hour.
Electric Oven Cost Comparison Across Rates
| Oven Wattage & Temperature | Effective Duty Cycle | Hourly kWh | At 15 ¢/kWh | At 20 ¢/kWh | At 30 ¢/kWh |
|---|---|---|---|---|---|
| Compact Oven (2,400 W at 350°F) | 50% Duty Cycle | 1.20 kWh/hr | $0.18 / hr | $0.24 / hr | $0.36 / hr |
| Standard Oven (3,500 W at 350°F) | 55% Duty Cycle | 1.92 kWh/hr | $0.29 / hr | $0.38 / hr | $0.58 / hr |
| Large Oven / Broil (4,500 W High Heat) | 75% Duty Cycle | 3.38 kWh/hr | $0.51 / hr | $0.68 / hr | $1.01 / hr |
Energy-Saving Kitchen Alternatives
For smaller meals, countertop convection ovens or air fryers draw 1,400W to 1,800W without requiring 0.8 kWh of preheating energy, saving 40% to 60% on cooking electricity.
