Formula usedEnergy (kWh) = watts × quantity × hours × days × operating factor ÷ 1,000
Your values in the formulaΣ (watts × quantity × hours/day × 30 ÷ 1,000) = 280.08 kWh
Assumptions and rounding- All preset wattages are editable planning values.
- Refrigerator cycling is represented by an editable-equivalent 35% running factor.
- Fixed charges, duties, taxes and slab effects are excluded.
Use this as a budget estimate. The appliance label, how often it runs and all charges on your tariff determine the real bill.
