- Monthly consumption: Multiply daily usage by 30 (days) and then by the kW used.
- Include the electricity cost: Multiply your monthly consumption by your local electricity cost (per kWh).
Here’s a simple formula for clarity:
- Monthly Cost = (Wattage / 1000) × Daily Hours × 30 × Electricity Cost per kWh
For example, if you have a 150-watt TV, watch it for 4 hours daily, and your electricity cost is $0.12 per kWh:
- Monthly Cost = (150 / 1000) × 4 × 30 × 0.12 = $2.16
This breakdown shows that your entertainment choices could have a moderate impact on your bill, and every little bit counts over time!
