Air conditioner electricity cost in Singapore

Year-round heat and humidity make compressor runtime, set point, room leakage, and the current quarterly electricity tariff central to cooling cost.

Rate used for the starting scenarioSGD 0.3478/kWh

Use the GST-inclusive regulated tariff or the exact retail-plan rate applying to the hours when the air conditioner operates.

Billing scopeSingapore

Confidence A 99/100. Effective 2026-07-01 to 2026-09-30.

Live local scenario

Calculate with an editable rate.

Air conditioners cycle or modulate, so scheduled hours alone overstate energy use. The active-runtime input represents average compressor load across the operating window.

Your scenario

Change any value. Results update instantly.

Active runtime accounts for cycling. Use 100% for devices that draw the rated power continuously.

The local calculation

AC cost = rated kW × scheduled hours × active-runtime share × tariff

The device model stays global. The currency, tariff scope, validity period, and billing cautions come from the Singapore data layer.

Before trusting the result

Three checks for Singapore

01

Model sleeping-hours and all-day use separately.

02

Use a higher duty cycle for humid rooms or low set points.

03

Refresh the rate when EMA publishes a new quarter.

Dehumidifier

Persistent humidity can keep a dehumidifier cycling for many hours, with extraction target, room leakage, and laundry drying driving consumption.

Water heater

Instant and storage water heaters have different power profiles, while shower duration and household frequency often matter more than the nameplate alone.
