Question 1

How is the electricity cost of an appliance computed?

Accepted Answer

Divide the wattage by 1,000 to get kilowatts, multiply by the hours of use to get kilowatt-hours, then multiply by your rate per kWh. A 950-watt aircon running 8 hours at ₱12 per kWh costs 0.95 times 8 times 12, about ₱91 for the night.

Question 2

How much does an aircon cost per hour in the Philippines?

Accepted Answer

At a rate of ₱12 per kWh, a non-inverter window unit costs roughly ₱6 per hour at 0.5 HP, ₱11 at 1.0 HP, and ₱17 at 1.5 HP. An inverter unit averages about a third less once the room reaches temperature, since the compressor slows down instead of running full blast.

Question 3

Where do I find my electricity rate per kWh?

Accepted Answer

It is on your bill. Divide the total amount due by the kWh consumed for that month and you get your effective rate, with all the generation, transmission, and tax lines already baked in. Meralco residential rates have been running near ₱12 per kWh; electric cooperatives in the provinces vary on either side of that.

Question 4

Where do I find an appliance's wattage?

Accepted Answer

Check the nameplate sticker at the back or side of the unit, the plug tag, or the manual. It is listed in watts (W) or kilowatts (kW). For aircons rated in horsepower, 1 HP of cooling draws roughly 900 to 1,000 watts on a non-inverter unit.

Question 5

Why is my actual bill different from the estimate?

Accepted Answer

Appliances rarely draw their full rated power the whole time. Aircon compressors cycle on and off once the room is cool, refrigerators run only part of each hour, and washing machines draw more during spin than wash. Rates also move a little every month with the generation charge. Treat the result as a good estimate, not a guaranteed figure.

Question 6

Does an inverter aircon really save money?

Accepted Answer

Generally yes, when it runs for long stretches. An inverter unit varies its compressor speed instead of switching between full power and off, and typically averages 30 to 40 percent less energy over a full night. For short bursts of use the gap narrows, since the savings come from the long steady cruise after the room cools.

Question 7

Is anything I enter saved or sent anywhere?

Accepted Answer

No. Every calculation runs privately on your device. Nothing you type is stored, tracked, or sent to a server.
