Enter your appliance's power consumption, daily usage hours, and electricity rate to find out exactly what it costs to run. The Electricity Cost Calculator breaks down your daily, monthly, and annual costs — so you can see which devices are draining your wallet and make smarter energy decisions.

The calculator converts your appliance's power rating to kilowatts, multiplies it by the number of hours used per day to get daily energy in kWh, then multiplies that by your electricity rate. The formula is: Cost = Power (kW) × Usage (hours) × Rate ($/kWh). Daily, monthly, and annual costs are then derived from the daily figure.
Electricity rates vary widely by country and region. In the US, the average rate is around $0.12–$0.16 per kWh. In the UK it's approximately £0.24–£0.30 per kWh, and in Europe rates commonly range from €0.20–€0.35 per kWh. Check your utility bill for your exact rate.
The main factors are the power rating of the appliance (in watts or kW), how many hours per day it runs, and your local electricity tariff. Seasonal usage patterns, off-peak vs. peak pricing, and appliance efficiency ratings also play a significant role in your total bill.
Find the wattage label on the appliance (usually on a sticker on the back or bottom), estimate how many hours a day you use it, and enter your electricity rate from your utility bill. The calculator handles the rest, giving you daily, monthly, and annual cost figures.
Switching to energy-efficient appliances (like LED bulbs or A+++ rated devices), reducing standby power, using appliances during off-peak hours, and improving home insulation are all effective strategies. Use this calculator to identify which devices cost the most to run.
HVAC systems (heating and air conditioning) are typically the biggest energy consumers, followed by electric water heaters, dryers, electric ovens, and refrigerators. High-wattage items like space heaters (1,500W) and hair dryers (2,000W) are costly if used frequently.
A kilowatt-hour is the standard unit of energy used by utility companies for billing. It equals the energy consumed by a 1,000-watt (1 kW) appliance running for one hour. For example, a 100W light bulb running for 10 hours uses 1 kWh of electricity.
Yes. The calculator accepts power inputs in Watts, Kilowatts, BTU/hour, and Horsepower. It automatically converts these to watts before calculating energy consumption, so you can use whatever unit is shown on your appliance's label.
