How much does it cost to run aircon in Singapore?
A typical 1.5 HP (≈1,500W) aircon running 8 hours/day at the SP Group rate of S$0.28/kWh costs roughly S$33–S$40 per month. A 2.0 HP unit running the same hours costs S$45–S$55/month.
How much can I save with an inverter aircon?
Inverter (5-tick NEA) aircons consume 25–35% less electricity than standard 3-tick models. On a 1.5 HP unit running 8 hours/day, that saves roughly S$10–S$15/month, or S$120–S$180/year.
What is the current SP Group electricity tariff?
SP Group publishes quarterly electricity tariffs for Singapore. The default in this calculator (S$0.28/kWh) reflects the regulated tariff as of Q1 2026. You can adjust it to your actual rate if you're on an open electricity market plan.
Why is my electricity bill so high even though I service my aircon?
A dirty evaporator coil, low refrigerant, or blocked air filter forces the compressor to work harder, increasing consumption by up to 20%. Regular servicing (every 3 months) and a chemical wash annually keeps efficiency up.
