Step 4: Calculate Monthly Energy Usage
To find the monthly energy usage, multiply the daily energy consumption by 30 (the days in a month).
Monthly Energy Usage (kWh) = Daily Energy Usage (kWh) × 30
For our example:
Monthly Energy Usage = 0.64 kWh × 30 = 19.2 kWh
Step 5: Estimate Your Costs
Finally, multiply your monthly energy usage by the cost of electricity per kilowatt-hour in your area to get your estimated monthly cost.
Estimated Monthly Cost = Monthly Energy Usage (kWh) × Cost per kWh
If your electricity costs $0.12 per kWh:
Estimated Monthly Cost = 19.2 kWh × $0.12 = $2.30
