How Much Electricity Does an Oven Use?
So how much electricity does an oven use? An electric oven typically draws 2,000 to 5,000 watts, with a separate stovetop burner or induction hob adding 1,000 to 3,000 watts on top of that when used at the same time. It's one of the higher-wattage appliances in the kitchen, though it only draws that full wattage while actively heating, not for the entire time food is inside — use the calculator below with your own oven's wattage and rate for a real estimate.

What affects how much electricity an oven uses
Target temperature is the biggest factor: a higher setting takes more energy to reach and more energy to maintain against heat loss. An oven doesn't run at full wattage continuously once preheated, its heating element cycles on and off to hold temperature, so real average draw over a cook time is somewhat below the rated wattage. Oven size, door seal condition, and how often the door is opened during cooking (which lets heat escape and makes the element work harder to recover) all affect actual usage too.
How to reduce your oven's electricity use
- Avoid opening the door to check on food, since each opening lets significant heat escape
- Use convection mode if available, since it often cooks faster at a lower effective temperature
- Batch-cook multiple dishes in one oven session instead of preheating separately for each
- Use a toaster oven or microwave for small items instead of heating up a full-size oven
Typical wattage figure: 2,000-5,000 W for the oven; 1,000-3,000 W for a stovetop burner or induction hob. Source: EnergySage — How Many Watts Does an Electric Oven and Stove Use?. This is a commonly cited industry estimate rather than a government-published figure. Actual draw depends heavily on the target temperature and whether it's gas or electric. We review this figure periodically and update it if the source changes; last checked September 2026.
Frequently asked questions
How many watts does an oven use?
An electric oven typically draws 2,000 to 5,000 watts, based on a commonly cited industry estimate, with a separate stovetop burner or induction hob adding 1,000 to 3,000 watts if used at the same time. This is not a government-published figure.
How much does it cost to run an oven?
A 3,000-watt oven run for one hour at the U.S. average rate of about 16.5 cents/kWh costs roughly $0.49, though the element cycles on and off once preheated rather than drawing full power the entire time. Use the calculator above with your own oven's wattage and typical cook time for an exact figure.
Does preheating waste a lot of electricity?
Preheating itself doesn't waste electricity, it's simply the energy needed to bring the oven up to temperature before cooking starts, and skipping it can lead to uneven or longer cooking. What does add unnecessary cost is preheating far earlier than needed and leaving the oven idling at temperature, or opening the door repeatedly, which lets heat escape and makes the element work harder to recover.
How can I reduce how much electricity my oven uses?
Avoid opening the door to check on food, since each opening lets heat escape and makes the element run longer to recover. Batch-cooking multiple items in one session, using convection mode if available, and reaching for a toaster oven or microwave for small items instead all help too.
