Breeze Electric — Home Electricity Costs | breezerelectric.com
A table of 12 common appliances with watts, kWh per hour of use, and the monthly cost at an illustrative tariff of 0.15 currency units per kWh.
Every appliance has a draw measured in watts — a rate, not a monthly figure. To get a monthly figure you need the rate, the hours of use, and the tariff. This page gives you the first and the third; the hours are the part only you know.
The table below lists twelve common appliances. Draw is in watts. The kWh column is the energy used per hour of use, which is the draw in kilowatts — 2000 watts is 2.0 kW, so one hour is 2.0 kWh. The cost column multiplies that by the illustrative tariff of 0.15 per kWh and assumes one hour of use per day for 30 days.
Two entries deserve a note. An electric kettle draws about 2000–3000 watts, but it runs for minutes, not hours, so its monthly cost is small: the worked example on this site has a 2000-watt kettle boiling 10 minutes a day using about 10 kWh and costing about 1.5 per month. A modern refrigerator averages 100–200 watts across a day — a lower rate, but continuous, so it lands higher on the bill.
On narrow screens, swipe or scroll the plate sideways.
Lighting is the entry where the swap is clearest: an LED bulb needs about 9–12 watts where the incandescent it replaced needed 60. Same task, roughly one-fifth the rate, and the saving runs every hour the light is on.
Standby appears twice, at 1 watt and at 10 watts, because a device on standby typically draws 1 to 10 watts and a household can run a dozen of them around the clock. Individually the figures are trivial; the last row of the table shows the dozen together.
Use the table by finding your appliance, taking its draw, estimating hours of use per month, and multiplying: watts × hours ÷ 1000 = kWh, then kWh × tariff = cost. The same three steps are set out in order on Read the Meter and the Bill.
