Understanding AC Energy Costs
This calculator helps you estimate how much it costs to run your air conditioner. Several factors affect your energy consumption:
- AC Size (HP/BTU): Larger units consume more power
- Energy Efficiency: Inverter ACs can be 30% more efficient than standard units
- Usage Hours: Running AC all day costs more than using it for a few hours
- Electricity Rate: TNB uses tiered pricing - more usage means higher rates
TNB Domestic Tariff Rates
Malaysia uses a tiered electricity pricing system. The more you consume, the higher the rate per kWh:
| Usage Tier | Rate (RM/kWh) |
|---|---|
| 1-200 kWh | RM 0.218 |
| 201-300 kWh | RM 0.334 |
| 301-600 kWh | RM 0.516 |
| 601-900 kWh | RM 0.546 |
| >900 kWh | RM 0.571 |
* Rates are based on TNB domestic tariff. Actual rates may vary.
Tips to Reduce AC Energy Costs
