How the math works
Monthly cost = watts × hours per day × 30 ÷ 1,000 × rate. The default rate is Meralco's current overall residential rate of ₱14.7424/kWh (2026-09); provincial co-ops differ, so edit the rate field if you're outside the Meralco franchise area. Wattages are typical average draw for Philippine models — see the full table in our appliance wattage guide.
Frequently asked questions
How much does aircon cost per hour in the Philippines?
A 1 HP non-inverter unit drawing ~1,000 W costs about ₱14.74 per hour at the current Meralco rate. An inverter unit of the same size averages ~600 W once the room is cool — about ₱8.85/hour.
Which appliance adds most to a Meralco bill?
Air conditioning, by far — 8 hours a night of a 1 HP non-inverter unit is roughly 240 kWh a month — over ₱3,500 at the current Meralco rate. The ref comes second because it runs 24/7, then water heaters if used daily.
Are these wattages exact?
They are typical average running watts for appliances sold in the Philippines, not nameplate maximums — compressors cycle on and off, so averages are what your bill actually reflects. For exact figures, check your unit’s energy label or use a plug-in power meter.
