Appliance Energy Calculator Philippines 2026: Monthly Cost Estimator
Ever wondered why your Meralco bill spikes when you run the air conditioner all day? This calculator helps you pinpoint exactly how much each appliance is costing you per month so you can make smarter decisions about your electricity use. The math is simple: convert the appliance's wattage to kilowatts, multiply by the hours it runs and the days per month, then multiply by your rate per kWh. Whether you want to compare an inverter aircon versus a standard unit, figure out how much your old ref is costing you, or justify switching to an LED television, this tool gives you a clear peso figure. All you need is the wattage from the label on the back of the appliance and your current electricity rate from your bill.

Frequently Asked Questions
The wattage is printed on a label affixed to the back or bottom of most appliances. It may appear as "W" (watts) or as a voltage and ampere rating from which you can calculate watts (Watts = Volts x Amps). For appliances with variable consumption like air conditioners and inverter refrigerators, use the rated or nominal wattage for a reasonable estimate.
