Electricity Cost Calculator – Calculate Device Power Bill Daily, Monthly and Yearly
The electricity cost calculator computes any home appliance's power consumption and cost based on usage hours and power rating (watts). Enter device power, daily usage time, and electricity unit price.
The tool shows consumption in kilowatt-hours (kWh) and costs per day, month, and year. You can add multiple devices and calculate total household consumption. Useful for identifying energy-saving opportunities.
How much electricity do home appliances use?
Electric sauna (8 kW) for one hour uses 8 kWh, costing about $1.20–1.60 per session. Washing machine (2 kW) uses about 1–1.5 kWh per load. TV (100–200 W) costs about $1.50–3 monthly. Refrigerator (100–150 W continuously) uses 70–100 kWh yearly, costing about $10–15/year.

Enter device power in watts and usage hours, and the calculator computes energy consumption and cost.
- Calculate individual device electricity consumption in kilowatt-hours (kWh).
- See cost in your currency at your selected electricity price.
- Compare different devices' consumption and find the biggest consumers.
Calculation is based on rated power and estimated usage time – actual consumption may differ.
- Many devices don't use rated power constantly (e.g., refrigerator cycles on and off).
- Standby power consumption can be significant annually.
- Electricity price varies by contract, time of day, and season.
Monitoring electricity consumption is the first step in energy saving.
- Biggest household electricity consumers are typically heating, hot water, and electric sauna.
- Energy rating (A–G) indicates device energy efficiency.
- Smart meter or smart plugs provide most accurate real consumption data.
