An appliance cost estimate should begin with the model label and your own bill—not a national average. Enter watts, daily runtime, days and the energy rate you actually pay. The result separates energy from any fixed bill charges and shows the exact kWh calculation. This makes the tool useful across the US, UK, Australia, UAE, Canada, Europe, New Zealand and Singapore without pretending that one tariff applies everywhere.
Use the current bill or tariff sheet, exact product label, location-specific solar estimate, or measured project dimensions. Example physical values teach the tool; zero money rates prevent an unsourced price from becoming a default claim.

The result reflects the values entered. Cycling, standby, taxes, delivery, fixed fees and tiered or time-of-use pricing can change the final bill.
A 100 W device used for 5 hours a day over 30 days uses 15 kWh before fixed charges. Enter your bill's rate to price that energy.
