How accurate is the appliance cost estimate?
It provides a reasonable estimate using the wattage × hours formula. Actual costs depend on your tariff slab, FPA, and whether the appliance runs at full wattage continuously.

FAQ
Frequently Asked Questions
Why do inverter ACs cost less to run?
Inverter ACs adjust compressor speed based on cooling demand, running at lower wattage most of the time. Non-inverter ACs run at full capacity and cycle on/off, consuming more energy overall.
What is the most expensive appliance to run?
Typically electric geysers, non-inverter ACs, and room heaters are the most expensive due to high wattage and extended usage. A non-inverter AC running 12 hours daily can cost Rs. 8,000+ per month.
How can I reduce my appliance electricity costs?
Use inverter models, reduce usage hours for high-wattage appliances, switch to LED lighting, and unplug devices when not in use to eliminate standby power consumption.
