Appliance Energy Cost Calculator
Calculate how much any electrical appliance (TV, gaming PC, microwave, space heater, washer) costs to run per hour, month, and year.
How to use the Appliance Energy Cost Calculator
- 1Enter appliance wattage in Watts (W).
- 2Enter average hours used per day.
- 3Enter your electricity tariff rate per kilowatt-hour ($/kWh or ₹/kWh).
How Appliance Cost is Calculated
Converts Watts to kWh: (Watts × Hours / 1000) and multiplies by utility rate per kWh.
Wattage ratings are listed on manufacturer appliance specification tags.
- 1Daily Energy = (1,500 × 6) / 1,000 = 9.0 kWh/day
- 2Monthly Consumption = 9.0 × 30 = 270 kWh
- 3Monthly Cost = 270 × $0.16 = $43.20/month
What affects Appliance Cost results
- Thermostat cycling: heaters and cooling units rarely draw continuous peak wattage.
Frequently Asked Questions
Where can I find the wattage of my appliance?
Every electrical appliance has a UL/CE specification label near the power cord or underside indicating Voltage (V), Amperes (A), and Watts (W).
Which household appliances consume the most electricity?
Space heating, air conditioning, electric water heaters, clothes dryers, and large refrigerators account for the vast majority of household power consumption.
