How to estimate and lower your electricity bill

Your electricity bill is mostly energy used, measured in kWh, multiplied by your rate. Each appliance uses power based on its wattage and how long it runs. Air conditioners, water heaters and refrigerators usually make up the biggest share, so knowing their cost tells you where to save first.

This calculator multiplies watts, hours and units for every appliance, then converts the total to pesos. The ranking helps you spot power hogs. Try changing hours or switching from a non-inverter to an inverter aircon to see the effect on your monthly cost.

How the electricity cost is calculated

Energy use in kWh equals watts times hours per day times days, divided by 1,000, then multiplied by how many units you have.
Cost equals kWh times your rate per kWh. Your real bill also includes taxes, fees and other charges, which is why we use an all-in rate.
Wattages shown are typical figures. Check the label on your own appliance, since models vary, and edit the watts if yours differs.
Refrigerators cycle on and off, so the default is an average draw over 24 hours, not the peak wattage on the label.

Tips to save more

Set your aircon to 24 to 26 degrees and use a fan to circulate air.
Switch to LED bulbs and unplug chargers and idle devices.
Run the washing machine and iron in batches instead of a little at a time.
Clean aircon filters and keep the refrigerator door closed to reduce wasted energy.

Frequently asked questions

How do I compute my electric bill per appliance?

Multiply the appliance watts by the hours you use it per day and the number of days, divide by 1,000 to get kWh, then multiply by your rate per kWh. The calculator does this for every appliance and adds them up.

What rate per kWh should I enter?

Use the total amount due on your latest bill divided by the kWh consumed. This gives an all-in rate that already includes generation, distribution, taxes and other charges, so the estimate is closer to your real bill.

Which appliance usually costs the most?

Air conditioners and water heaters usually top the list, followed by the refrigerator because it runs all day. Check the ranked list to see which one is highest in your home.

Why is my estimate different from my bill?

Estimates assume steady use and typical wattage. Your real bill reflects actual use, appliance age, room size, seasonal rate changes and other charges.

How can I lower my electricity bill?

Raise the aircon temperature to 24 to 26 degrees, use an inverter model when you upgrade, switch to LED bulbs, unplug idle devices and avoid peak-hour appliance use where your plan allows.
