AC Energy Cost Estimator
Estimate your monthly electricity cost from running your aircon. Based on SP Group's current tariff of S$0.28/kWh.
Estimates use Singapore's SP Group regulated tariff (S$0.28/kWh). Actual costs vary with your electricity plan, AC efficiency, outdoor temperature, and usage patterns.
How your aircon affects your electricity bill
Dirty coils waste electricity
A clogged evaporator coil forces the compressor to run longer to hit the target temperature. Studies show a build-up of just 0.04 inches of grime reduces efficiency by up to 21%. A chemical wash removes this build-up, cutting wasted run-time.
Inverter AC vs. standard
Inverter (5-star) ACs modulate compressor speed rather than switching on/off, using 20–40% less electricity than standard units. At S$0.28/kWh running 8 hours/day, upgrading from standard to inverter on a 1.5 HP unit saves roughly S$25–S$35 per month.
SP Group electricity tariff
The regulated tariff for Singapore homes is approximately S$0.28/kWh (SP Group, 2025). Open Electricity Market retailers may offer rates 10–20% below this. Update the rate field if you're on a different plan.
Typical Singapore household spend
A 3-bedroom HDB with two 1-HP ACs running 8 hours a day typically spends S$60–S$90/month on cooling. After a chemical wash, many customers report a 15–25% reduction in the following month's bill.
