Understanding Standby: Reduce costs by unplugging idle components entirely. Minor constant drops multiplied across modern electronic ecosystems silently inflate household margins over time.

⚡ What Is This Calculator?

This free tool helps you estimate how much electricity your household appliances cost to run. Whether it's your washing machine, TV, or gaming console, simply enter the wattage and usage time to see daily, monthly, and yearly costs.

The Standby Calculator reveals hidden "vampire" costs — the energy devices consume even when switched off but still plugged in.

📝 How To Use

Select your preferred currency from the top control bar.
Enter the appliance wattage (check the label on the device or its manual).
Enter how many hours per day you use the appliance.
Adjust the electricity rate to match your tariff (default is £0.28/kWh).
Click Calculate to see your costs instantly.

💡 Energy Saving Tips

Switch off appliances at the wall instead of leaving them on standby.
Use a smart power strip to cut power to multiple devices at once.
Run washing machines and dishwashers on full loads only.
Switch to LED bulbs — they use up to 80% less energy than incandescent.
Set your thermostat 1°C lower to save around £80–£100 per year.
Use a timer for electric heaters to avoid running them unnecessarily.
