Electricity Usage Calculator
Add your appliances' wattage and daily hours to estimate their electricity use in kWh, and optionally an estimated cost.
Your appliances
Find the wattage (W) on the appliance's label or manual. If the label lists only volts (V) and amps (A), watts ≈ volts × amps. Air conditioners and fridges cycle on and off, so their real use is usually lower than wattage × hours.
Leave blank to see energy use only. You can estimate a rate from a past bill: amount ÷ kWh.
Estimated energy use
Enter watts and hours per day for at least one appliance.
These are estimates, not a CFE bill. CFE's residential tariffs charge different prices as your use goes up, depend on your tariff and subsidy, and cover your own billing period, so a flat rate per kWh won't match your bill exactly.
How it's calculated
Watts × hours per day × how many ÷ 1,000 = kWh per day. The 30-day and 60-day totals multiply that by 30 and 60. The cost is your rate × kWh, only when you enter a rate.
Why your bill will be different
This is an energy-use estimate, not a CFE bill calculator. Your actual bill depends on your tariff, how much of your use falls into each price tier, any subsidy, the length of your billing period, taxes and other charges.
