Most Instant Pots draw roughly 700 to 1,200 watts while actively heating, but because they cycle on/off and cook times vary, many households land around 0.2 to 1.5 kWh/day depending on how often they use it.

Quick Answer
Most Instant Pots draw roughly 700 to 1,200 watts while actively heating, but because they cycle on/off and cook times vary, many households land around 0.2 to 1.5 kWh/day depending on how often they use it.
Detailed Explanation
Instant Pots (and similar electric pressure cookers) don’t pull their nameplate watts constantly. They usually draw near their rated power during preheat/pressure build, then cycle on and off to maintain temperature and pressure. That’s why daily kWh is better estimated from minutes of active heating, not “watts x total cook time.”
Different modes can change energy use:
- Pressure cook: higher draw during warm-up, then cycling
- Sauté: more continuous heating (often higher average watts)
- Keep warm: usually low average watts, but can add up over many hours

Watt Table
| Instant Pot Mode / Use | Typical Running Watts (Active Heating) | Typical Starting Watts | Typical Daily Energy |
|---|---|---|---|
| Pressure cook (warm-up phase) | 700 - 1200 W | 700 - 1300 W | 0.20 - 1.20 kWh/day |
| Pressure cook (maintain/cycling) | 100 - 500 W (average) | N/A | included above |
| Sauté / sear | 700 - 1200 W | 700 - 1300 W | 0.30 - 1.50 kWh/day |
| Keep warm (hours) | 20 - 120 W (average) | N/A | 0.05 - 0.60 kWh/day |
Calculation Example
Example: An Instant Pot draws about 1,000 W during active heating. Over the day it actively heats for 25 minutes total (preheat + cycling), plus “keep warm” averages 60 W for 2 hours.
- Active heat time in hours: 25 / 60 = 0.42 h
- Active heat kWh/day = (1,000 x 0.42) / 1000 = 0.42 kWh/day
- Keep warm kWh/day = (60 x 2) / 1000 = 0.12 kWh/day
- Total = 0.54 kWh/day
- At $0.16/kWh, monthly cost is about $2.59

Tips to Reduce Power Usage
- Use pressure cooking instead of long simmering when it fits the recipe.
- Avoid keeping “keep warm” on for many hours if food will be served soon.
- Batch cook (2 meals at once) to reduce repeated warm-up cycles.
- Use a lid when sautéing to reach temperature faster (when safe for the recipe).
FAQs
Does an Instant Pot have a startup surge?
Not like a motor compressor. The main spike is simply when the heating element turns on; the “starting” draw is usually close to running watts.
Why does my Instant Pot kWh/day vary so much?
Warm-up duration, recipe volume, sauté usage, and how long “keep warm” stays on can change daily energy dramatically.
Is it cheaper than an oven?
Often yes for many meals, because it heats a smaller mass and can cook faster, but it depends on the recipe and cooking time.
