How much does it cost to run an instant pot?
An Instant Pot is a multi-function electric pressure cooker that uses high pressure and temperature to cook food in a fraction of the time a conventional oven or stovetop would require. Because it traps steam and heat inside a sealed vessel, it dramatically reduces cooking time—which in turn keeps electricity consumption surprisingly modest compared to other kitchen appliances.

At 1000 watts used 0.5 hours a day, an instant pot costs about $0.09 per day, $1.77 per month and $21.25 per year on an average rate of 17¢ per kWh — roughly 125 kWh and 50 kg of CO₂ over a year. Enter your own electricity rate and usage in the calculator above for a figure matched to your bill.
The efficiency of an Instant Pot comes down to physics: a sealed environment under pressure allows food to cook at higher temperatures without evaporation, meaning you can make dried beans tender in 30 minutes instead of two hours. This short burst of intense cooking is far less energy-intensive than running an oven for extended periods or simmering on a stovetop where heat gradually escapes. Most Instant Pot models draw around 1000 watts during active heating, but because actual cooking sessions are brief—rarely exceeding 45 minutes from preheat to done—the total daily energy consumption is modest, especially considering that many households use it only a few times per week.
Where people lose efficiency with pressure cooking is in misunderstanding the preheat cycle and heat-up demands. The appliance must reach full pressure before cooking actually begins, and this pressurization phase consumes the most power. Overfilling the pot or cooking very large batches can extend preheat time. Conversely, batch-cooking several meals at once—preparing a large pot of stock or legumes that you'll use throughout the week—spreads the energy cost across multiple servings and is genuinely economical. The lid seal and pressure valve matter too; a worn gasket forces the unit to work harder to maintain pressure, consuming more electricity.
Instant Pots vary significantly in wattage and efficiency features. Newer models often include quieter, more efficient heating elements and better insulation that reduces the energy needed to maintain pressure once it's reached. Stainless steel inner pots conduct heat more evenly than non-stick alternatives, reducing hot spots and uneven cooking that might force you to re-run a cycle. If you're in the market for a replacement, comparing wattage across models and checking for user reviews mentioning heat consistency can help you choose a unit that doesn't waste energy on inefficient heating or repeated cook attempts.
Common mistakes that inflate Instant Pot electricity use include opening the lid mid-cycle to check on food, which releases pressure and requires re-pressurization; cooking small portions that don't justify the preheat energy; and using it for foods that cook almost as fast on the stove, like frozen vegetables or thin pasta. The appliance shines with tough, long-cooking ingredients: whole grains, dried beans, tough cuts of meat, stock, and stews. For those meals, the energy savings versus conventional methods are real. It's also worth noting that using the keep-warm function for extended periods after cooking—hours rather than minutes—does consume ongoing electricity, so turning the appliance off once food is done is the efficient choice.
Frequently asked questions
- Does the Instant Pot use more or less electricity than cooking the same food in a conventional oven?
- Far less. A typical oven runs at 3000–5000 watts and cooks a pot roast or beans for hours, while an Instant Pot at 1000 watts finishes the same task in under an hour. The sealed pressure environment means you're not continuously fighting heat loss, making it one of the most efficient cooking methods for long-cooking foods.
- What's the single biggest factor that determines how much electricity my Instant Pot uses per meal?
- Cooking time, directly. Every minute of the preheat and pressure-cooking phase costs electricity proportionally. Cooking foods suited to pressure cooking—dried beans, grains, tough cuts of meat—keeps sessions short. Cooking quick foods like fresh vegetables wastes the energy spent on pressurization without much benefit.
- Does keeping an Instant Pot plugged in when I'm not using it cost me money?
- Not significantly. Most modern Instant Pots draw minimal standby power when idle and unplugged, the main risk is if you repeatedly set it to keep-warm by accident or leave it on the heating function after cooking finishes. If you use it regularly, leaving it plugged in is fine; unplugging between uses saves trivial amounts.
- Is it more efficient to cook one large batch or multiple smaller meals?
- One large batch is more efficient. The preheat and pressurization phase costs energy regardless of what's inside, so cooking a full 6-quart pot of chili and freezing portions spreads that energy cost across many servings. Multiple small cook cycles duplicate the preheat expense.
- What maintenance reduces my Instant Pot's electricity consumption?
- Keeping the rubber gasket clean and replacing it every 12–18 months is the most important step. A worn or dirty seal forces the heating element to work longer to build and maintain pressure. Also regularly clean the rim of the pot to ensure a tight seal, and check that the pressure valve isn't partially blocked by residue.
- Does cooking frozen food from the state versus thawing it first change the electricity used?
- Cooking from frozen takes somewhat longer to pressurize, which costs extra electricity. Thawing food in the refrigerator overnight before cooking reduces preheat time and energy consumption, a small but measurable efficiency gain if you cook frequently.
