Meralco Appliance Calculator: How Much Each Device Costs

The Meralco Appliance Calculator helps households estimate how much electricity each appliance consumes daily, weekly, and monthly. Whether you want to reduce your power bill, track air conditioner costs, or manage household electricity usage more efficiently, this tool provides a simple way to understand your consumption.

Hourly Estimates Track appliance consumption per hour.

Monthly Costing Estimate your total appliance expenses.

Energy Monitoring Identify appliances consuming the most power.

Budget Planning Adjust usage based on your electricity budget.

What is the Meralco Appliance Calculator?

The Meralco Appliance Calculator, also called App Cal, is an online electricity consumption estimator developed to help customers understand how much energy their appliances use. The calculator estimates the operating cost of appliances based on:

Monthly electricity bill
Appliance wattage
Hours used daily
Days used weekly
Weeks used monthly

Using these details, the system generates estimated electricity costs per hour, day, week, and month. The tool is especially useful for households trying to lower their Meralco bills during hotter months when electricity consumption usually increases because of air conditioners, refrigerators, and cooling appliances.

Cooling appliances such as air conditioners and refrigerators may consume more electricity during summer months because compressors work harder in hotter temperatures.

How the Appliance Calculator Works

The App Cal estimates appliance consumption using your current Meralco rate per kilowatt-hour (kWh) and the appliance’s estimated wattage. The formula behind the calculation is based on: Watts × Hours Used ÷ 1000 = kWh Consumption Once the estimated kWh usage is calculated, it is multiplied by the current Meralco electricity rate to estimate your appliance cost.

If you want to manually estimate your bill using current electricity rates, you can also use our dedicated calculator here:

How to Use the Meralco Appliance Calculator

Step 1: Open the Appliance Calculator

Access the Meralco Appliance Calculator using the web version or the My Meralco mobile app.

The calculator works on both desktop and mobile devices, making it easy to estimate electricity usage anywhere.

Step 2: Enter Your Monthly Bill Amount

Input your average monthly electricity bill based on your recent Meralco statements.

The calculator uses this amount to estimate your applicable electricity rate and compute appliance costs more accurately.

For best results, use your 12-month average consumption shown on your Meralco bill.

Step 3: Select an Appliance

Choose the appliance you want to calculate. The App Cal includes various categories such as:

Air conditioners
Electric fans
Refrigerators
Televisions
Computers
Lighting
Kitchen appliances
Washers and dryers

You can search appliances directly or filter by category.

Step 4: Set Usage Hours

Adjust the number of hours the appliance is used daily.

For example:

Air conditioner: 8 hours daily
Electric fan: 12 hours daily
Television: 5 hours daily

The more accurate your inputs are, the closer the estimate will be to your actual electricity usage.

Step 5: Select Days and Weeks Used

Choose how many days per week and weeks per month you typically use the appliance.

Most household appliances are usually set to:

7 days per week
4 weeks per month

Step 6: Click Calculate

Once all information is complete, click the Calculate button.

The calculator will display:

Cost per hour
Cost per day
Cost per week
Cost per month

Estimated Appliance Electricity Costs

Appliance	Estimated Wattage	Hours Daily	Estimated Monthly Cost
1HP Inverter Air Conditioner	800W	8 Hours	₱1,100 – ₱1,500
Electric Fan	75W	12 Hours	₱250 – ₱400
Refrigerator	150W	24 Hours	₱700 – ₱1,200
LED Television	100W	6 Hours	₱200 – ₱350
Rice Cooker	700W	1 Hour	₱250 – ₱350
Washing Machine	500W	1 Hour	₱150 – ₱300

Manual Appliance Consumption Computation

If you prefer manual computation, follow this formula:

Wattage × Hours Used Per Day = Watt-Hours

Watt-Hours ÷ 1000 = kWh

kWh × Meralco Rate = Estimated Cost

Example:

Electric fan wattage: 100W
Used: 10 hours daily
100 × 10 = 1000 watt-hours
1000 ÷ 1000 = 1 kWh daily
1 kWh × ₱14 = ₱14 daily estimate

Tips to Reduce Appliance Electricity Costs

Use Inverter Appliances

Inverter air conditioners and refrigerators consume less electricity compared to older non-inverter models.

Unplug Idle Devices

Appliances still consume standby power even when not actively used.

Set Aircon to 25°C

Meralco recommends setting air conditioners to 25°C for better energy efficiency.

Use Natural Lighting

Reducing daytime lighting usage can lower monthly consumption.

Clean Appliances Regularly

Dirty filters and blocked vents force appliances to work harder and consume more power.

Track Consumption Monthly

Monitoring your appliance usage monthly helps identify unusual increases early.

Why Electricity Bills Increase

Several factors affect your monthly Meralco bill:

Hot weather increases cooling appliance usage
Higher Meralco generation charges
Longer appliance operating hours
Old appliances consuming more electricity
Increased household occupancy
Additional appliances connected at home

During summer months, electricity consumption can increase by 20% to 33% because air conditioners and refrigerators work harder.
