HOW IT WORKS
A result to understand, not just read.
Use the wattage on the appliance label or product specifications, then enter realistic daily use and the price per kWh shown on your bill. Change any value to compare scenarios instantly.
- Watts are converted to kilowatts before energy use is calculated.
- The annual estimate assumes the same monthly pattern for twelve months.
- Thermostats, duty cycles and variable-speed equipment can make real consumption differ from nameplate wattage.
FREQUENTLY ASKED QUESTIONS
Where can I find the wattage?+
Check the appliance label, manual or manufacturer specifications.
Which electricity price should I enter?+
Use an all-in price per kWh from your bill when possible, so the estimate reflects the amount you actually pay.
