Important Note About the Assumed Rate per Kilowatt-hour: The price per kWh shown above is based on June 2010 Meralco electricity rates. The assumed price of electricity per kilowatt-hour is derived statistically and uses representative rate per bill amount bracket group. These assumed data are updated on a regular basis as deemed necessary by Meralco AppC al application s. This computation may vary from the actual consumption and rates reflected in the customer’s Meralco monthly electric bill and therefore, this computation should not be used in any way for billing purposes, complaints or concerns against Meralco. This computation should not be used by the customer to estimate electric consumption of appliances and/or equipment used for non-residential or business or commercial purposes. 1.

FOR REFRIGERATORS & FREEZERS Formula: Estimated cost per hour = [Rate per kilowatt-hour x (appliance wattage/ 1000) x 14 hours ]/ 24 hours per day Example: For a 6 cubic feet refrigerator for a household with an average monthly bill of P2,500.00. C ost per hour = [Rate per kilowatt-hour x (appliance wattage/ 1000) x 14 hours] / 24 hours per day C ost per hour = [P10.50 x (100 watts /1000) x 14 hours]/ 24 hours per day C ost per hour = [P10.50 x (.10 kilowatt) x 14 hours]/ 24 hours per day C ost per hour = [P14.70]/ 24 hours per day C ost per hour = P00.61 C ost per month = P00.61x number of hours used in one month

2.

FOR AIR CONDITIONING UNITS Formula C ost per hour = Rate x [(appliance wattage x 0.8 x 0.8) + (appliance wattage x 0.2)] / 1000) Example: For a 1 horsepower (944 watts) air conditioner for a household with an average monthly bill of P2,500.00. C ost per hour = Rate x [(appliance wattage x 0.8 x 0.8) + (appliance wattage x 0.2)] / 1000 C ost per hour = P10.50 x [(944 watts x 0.8 x 0.8) + (944 watts x 0.2)] / 1000 C ost per hour = P10.50 x [(604.16) + (188.8)] / 1000 C ost per hour = P10.50 x [792.96] / 1000 C ost per hour = P10.50 x 0.79 kilowatt C ost per hour = P8.30 C ost per month = P8.30 x number of hours used in one month

3.

FOR ALL OTHER APPLIANCES Formula: C ost per hour = Rate x (appliance wattage / 1000) Example: For a 29-inch color TV set for a household with an average monthly bill of P2,500.00. C ost per hour = Rate x (appliance wattage / 1000) C ost per hour = P10.50 x (145 watts / 1000)
