Estimate how much your electric stove, burner, cooktop, or oven adds to your bill using watts, time, days, and price.

How to use our Electric Stove Running Cost Calculator
- Enter Stove power (watts) for one burner, cooktop, or oven from the label, manual, or product page.
- Enter Time used on a cooking day (hours) and Cooking days per month for the cooking routine you want to estimate.
- Enter Electricity price ($ per kWh) from your electric bill, using the combined supply and delivery price when possible.
- Open Advanced options if you use more than one similar heating area at once or want to lower Average use of full power (percent) for simmering or oven cycling.
- Click Calculate, then sanity-check Average power counted and Electricity used per month. If they look too high, recheck the wattage, number of heating areas, and percent of full power.
Definitions
Stove power (watts): How fast one burner, cooktop, or oven uses electricity at its rated power. Watts measure power at a specific moment [1].
Electricity used per month (kWh): The estimated amount of electricity used by the cooking routine for the month. A kilowatt-hour is energy use over time.
Electricity price ($ per kWh): The price you pay for each kWh on your electric bill. If your bill separates supply and delivery, add the per-kWh parts together when possible.
Similar heating areas on at once: The number of same-size or close-in-wattage burners or heating zones running at the same time.
Average use of full power (percent): The average share of rated power counted. Use 100 for a high estimate, or a lower percent for lower heat, simmering, or cycling.
Average power counted: The wattage used in the math after multiplying stove power by heating areas and percent of full power.
Cost per hour while on: The estimated cost for one hour at the adjusted average power and your entered electric price.
Common mistakes and quick fixes
Mistake: Entering kilowatts in Stove power (watts) , such as 2 for a 2 kW burner.
Fix: Convert to watts first, so 2 kW becomes 2000 in Stove power (watts) .
Mistake: Using total kitchen time instead of on-time for Time used on a cooking day (hours) .
Fix: Count only the time the burner, cooktop, or oven is actually on.
Mistake: Putting all calendar days into Cooking days per month when you only cook on this stove a few days.
Fix: Enter only the days this stove setup is used, not every day of the month unless that is true.
Mistake: Leaving out delivery charges when entering Electricity price ($ per kWh) .
Fix: Use the all-in per-kWh price from your bill when you can, including supply and delivery per-kWh charges.
Mistake: Using Similar heating areas on at once for burners with very different wattages.
Fix: For very different burners or an oven plus burner, run separate calculations and add the Estimated monthly cost results.
Mistake: Keeping Average use of full power (percent) at 100 for simmering or an oven that cycles.
Fix: Lower the percent if you want an average-use estimate, then check Average power counted .
Limitations & Key Assumptions / Boundary Conditions
- The estimate covers only the stove setup you enter. It does not include lights, fans, microwaves, or other kitchen appliances.
- Rated wattage is often higher than real average use during low heat, simmering, or oven cycling. Use Average use of full power (percent) to adjust for that.
- Similar heating areas on at once works best when the heating areas have about the same wattage. For very different wattages, run separate calculations and add the costs.
- The yearly cost assumes the entered month is typical for all 12 months. Seasonal cooking changes can make the real yearly cost higher or lower.
- The calculator uses the electric price you enter. Tiered rates, time-of-use rates, minimum charges, taxes, and fixed monthly fees can change the bill impact.
- Zero hours or zero cooking days correctly returns $0 and 0 kWh, because no stove running time is being counted.
Methodology
How the calculation works
The calculator estimates electricity use from adjusted power and time, then multiplies that energy by your entered price. Watts measure power, and electricity use over time is measured in watthours or kilowatthours [1].
average_power_watts = power_watts * heating_areas_count * (full_power_percent / 100)
average_power_kw = average_power_watts / 1000
monthly_kwh = average_power_kw * hours_per_cooking_day * cooking_days_per_month
monthly_cost = monthly_kwh * electricity_rate
cost_per_cooking_day = average_power_kw * hours_per_cooking_day * electricity_rate
cost_per_hour_on = average_power_kw * electricity_rate
yearly_cost = monthly_cost * 12
Worked example
For a 2000 W stove used 1 hour per cooking day, 30 cooking days per month, at $0.18 per kWh, with 1 heating area at 100 percent power:
average power is 2000 W, or 2 kW. Monthly electricity use is 2 kW * 1 hour * 30 days = 60 kWh. Estimated monthly cost is 60 kWh * $0.18 = $10.80. The yearly estimate is $10.80 * 12 = $129.60 if that month is typical.
Result order
Estimated monthly cost is shown first because it is the main bill estimate. The yearly cost, per-day cost, per-hour cost, kWh use, and average power are supporting results that help you compare routines and check whether the inputs look reasonable.
