How This Calculation Works (User-Friendly)

1) We measure 3-phase current from your incoming supply at up to 4 stages:

Stage 1: Normal loads + Aircons on
Stage 2: Aircons on but compressor(s) off
Stage 3: Aircons off (only lights, fans, fridge, electronics, etc.)
Stage 4: Minimal loads (lights/fans also off)

2) We also estimate usage of each appliance (e.g. fridge, aircon, lights) based on daily usage hours and days per week.

3) Finally, pick either Tariff A (residential) or Tariff B (commercial) and hit "Calculate" to see the monthly bill.

If you're unsure about any value, leave the default or speak to an electrician for help. Typical Power Factor is around 0.8.
