You’ve probably typed “how much electricity does an electric burner use” into a search bar and got a single number back, something like “around 1.5 kilowatt-hours per hour.” That number isn’t wrong, but it’s also not yours. It doesn’t account for your burner size, your power setting, or the rate you pay per kilowatt-hour. So you end up guessing, and that guess is usually wrong.
The real answer depends on three things you can find in about two minutes: the wattage stamped on your burner, the hours you actually cook, and your local electricity rate. As of 2026, the average U.S. household pays roughly 14.3 cents per kWh (per EIA data). Once you know your own numbers, the calculation takes about thirty seconds.
Let’s walk through exactly how to find them.

Quick Answer
An electric burner uses between 800 and 2500 watts. A typical medium burner runs at 1200 watts on high. That costs about 14 to 18 cents per hour at average U.S. rates.
Smaller burners cost less. Triple-ring or boost modes cost more. Your actual total depends on how long and how often you cook.
The Real Problem: Why “Average” Numbers Don’t Help You
A one-size-fits-all wattage figure gives you a rough ballpark, but it can’t tell you what your burner actually costs you. Two people can cook the same meal and pay very different amounts. One uses a small 800‑W burner on low for twenty minutes.
Another uses a 2000‑W burner on high for forty minutes. The difference in cost is nearly tenfold.
Manufacturer specifications show that a single portable burner often lists its wattage on a sticker on the underside or side. A built‑in cooktop may have a label on the back or inside the manual. That number is the key to your calculation.
Without it, you are working from an estimate that could be off by 50 percent or more.
Aggregate reviews and utility data confirm that most people underestimate their burner use by at least a third. They assume “low” means a fraction of the wattage, but many electric burners cycle on and off at full power even on lower settings. That means the burner still draws full wattage during the “on” part of the cycle.
You need to account for that, too.
What You Actually Need to Know: Your Burner’s Wattage, Your Rate, Your Habits
Three variables drive your total cost. Let’s pull each one.
Your burner’s wattage. Look for a number like “1500 W” or “1.5 kW” on the burner itself, the cooktop chassis, or the user manual. Common values:
| Burner size | Typical wattage |
|---|---|
| Small (6‑inch) | 800 – 1000 W |
| Medium (8‑inch) | 1200 – 1500 W |
| Large (10‑inch) | 1800 – 2200 W |
| Triple‑ring / boost | 2500 – 3000 W |
Your electricity rate. Find your latest utility bill. Look for “Energy Charge” or “kWh rate.” It is usually a flat number like $0.143 per kWh. If you have a time‑of‑use plan, use the rate for the hours you cook most often.
Your cooking time and setting. Keep a log for three typical days. Note which burner you use, what setting (low, medium, high), and how many minutes. Be honest about the “on” time, a simmer that runs for an hour counts as a full hour, even if the burner cycles.
Once you have these numbers, you can plug them into a simple formula. That is exactly what the next section covers.

The Simple 4‑Step Workflow to Calculate Your Exact Cost
Here is the step‑by‑step process that works for any electric burner, any rate, any cooking habit.
Step 1: Convert watts to kilowatts. Divide the burner’s wattage by 1000. A 1500‑W burner becomes 1.5 kW. A 2000‑W burner becomes 2.0 kW.
Step 2: Multiply by hours used per session. If you cook for 0.5 hours (30 minutes) on that burner, multiply: 1.5 kW × 0.5 hours = 0.75 kWh for that session.
Step 3: Account for duty cycle on lower settings. Many electric burners cycle on and off even at “low.” A burner set to medium may run only 60 percent of the time. Multiply the session kWh by the duty‑cycle fraction. For example, 0.75 kWh × 0.6 = 0.45 kWh true consumption.
Step 4: Multiply by your electricity rate. If your rate is 14.3 cents per kWh, then 0.45 kWh × $0.143 = about 6.4 cents for that cooking session.
To get a monthly total, sum your sessions. A heavy cook using a medium burner for one hour daily at medium setting (60% duty) would consume roughly 0.9 kWh per day, or 27 kWh per month. At 14.3¢/kWh, that is about $3.86 per month for that one burner.

If you want the most accurate number, use a plug‑in power meter (often called a Kill‑A‑Watt) between the burner and the outlet. It logs real‑time wattage and cumulative kWh. One week of data beats any estimate.
Common Mistakes That Throw Off Your Numbers (And How to Avoid Them)
Even with the right formula, small errors can turn a reasonable guess into a wild one. Here are the four biggest mistakes I see in our research.
Mistake 1: Using the Burner’s Peak Wattage for Every Setting
A burner set to “low” does not draw its full rated wattage continuously. It cycles. If you assume full wattage for the whole cooking time, you triple your cost estimate.
Fix: Estimate the duty cycle (50, 70% for medium, 30, 50% for low) or use a power meter.
Mistake 2: Forgetting the Burner When It’s on “Simmer”
A simmer setting still uses electricity. It may cycle less often, but the heat has to stay hot. That slow simmer for an hour can add up.
Track it honestly.
Mistake 3: Misreading Your Electricity Bill
Some bills show a flat rate that already includes delivery fees. Others show a separate “supply” charge. Use the total per-kWh cost (supply + delivery) for accuracy.
If you are on a time-of-use plan, use the rate during your cooking hours.
Mistake 4: Ignoring Multiple Burners
If you use two burners at once, you need to calculate each separately and add them. A big stovetop meal can easily use 3–4 kW total for an hour, costing upwards of 50 cents in a high-rate area.
Avoid these pitfalls and your numbers will be within 5–10 percent of reality. That is good enough to know whether that electric burner is costing you noticeably more than gas or induction.

What If You Don’t Know Your Burner’s Wattage? (Decision Tree for Finding It)
Not every burner has a readable label. Maybe it wore off, or you’re using a secondhand cooktop. You still have three reliable ways to find the number.
Let’s walk them in order of ease.
Path A: Check the manufacturer’s model number online. Look on the underside of a portable burner or the back edge of a built-in cooktop for a model tag. Type that number into a search engine with the word “specs.” Most manufacturers post wattage in their product PDFs. This works about 80 percent of the time.
Path B: Use a multimeter to measure resistance. If you cannot find the label, unplug the burner and use a multimeter set to ohms (Ω). Touch the probes to the two prongs of the heating element. A typical reading is 10, 20 Ω for a 1500‑W burner at 120 volts.
Use the formula: watts = volts² ÷ resistance. For a 120‑V circuit, 120² ÷ 15 Ω = 960 watts. This method is accurate within 5 percent.

Path C: Measure with a plug-in power meter. The easiest and most accurate method. Plug the burner into a Kill‑A‑Watt or similar meter, turn it on high for one minute, and read the wattage. That is your burner’s actual draw.
No math required.
If you try all three and still cannot get a number, assume 1500 W for a medium burner and 1000 W for a small one. These are safe averages for a typical US 120‑V cooktop.
Real‑World Scenarios: What Different Users Actually Pay
Numbers make more sense when you see them in action. Here are three realistic profiles based on aggregate user feedback and utility data.
The daily batch cook. Someone who cooks one large meal per day using a medium burner (1200 W) on high for 30 minutes, plus a small burner (800 W) on low for 20 minutes. The medium burner consumes 0.6 kWh per session (60% duty on high), and the small burner consumes about 0.13 kWh (50% duty on low). Total daily: 0.73 kWh.
At 14.3¢/kWh, that is 10.4¢ per day, or about $3.12 per month.
The weekend warrior. Someone who cooks only on Saturday and Sunday, using a large burner (1800 W) on high for an hour each day. The burner runs at full power for most of that hour. Each session uses 1.8 kWh.
Two sessions per week equals 3.6 kWh per week, or about 14.4 kWh per month. At 14.3¢/kWh, that is roughly $2.06 per month.
The heavy user with multiple burners. A family that cooks dinner nightly using two burners simultaneously, a medium (1200 W) and a large (1800 W), each on medium for 45 minutes. The medium burner uses about 0.54 kWh per session (60% duty), and the large uses about 0.81 kWh. Total per night: 1.35 kWh.
Over 30 days, that is 40.5 kWh per month. At 14.3¢/kWh, that comes to about $5.79 per month for the stovetop alone.
These scenarios show that even frequent use rarely costs more than a few dollars per month for the burners themselves. The oven is what usually drives your electric bill if you’re curious about comparing to a different cooking method, like an induction cooktop that runs more efficiently.
Frequently Asked Questions
Does a burner use less electricity on a lower setting?
Yes, but not in a straight line. Most electric burners cycle on and off at full wattage on lower settings. So “low” means the burner runs less often, but when it runs, it draws the same full power.
A power meter is the only way to know your true duty cycle.
How much does it cost to run an electric burner for one hour?
At 14.3¢/kWh, a 1500‑W burner on high costs about 21.5¢ for one continuous hour. A 1000‑W burner costs about 14.3¢. Those numbers drop by 30 to 50 percent when you account for cycling on medium or low settings.
Is an electric burner cheaper than gas?
It depends on your local rates. In most of the US, electricity costs more per unit of heat than natural gas. However, electric burners lose less heat to the room than gas burners, so the efficiency difference can narrow the gap.
Use the formula in this guide to compare your actual costs.
Does an electric burner use electricity when turned off?
No. There is no standby draw on a standard electric burner. Once you flip the switch to off or unplug the unit, it draws zero power.
Any residual heat is just stored thermal energy, not ongoing electricity use.
Can I use an electric burner on a solar or battery system?
Yes, but you need to account for the surge. A 1500‑W burner draws about 12.5 amps at 120 volts. Make sure your inverter can handle that continuous load and your battery bank has enough capacity for your cooking session plus other appliances.
