How to Calculate Your Exact Daily Cost
Step 1: Check your monthly kWh usage
Step 2: Divide by 30
Step 3: Multiply by your rate per kWh
Example:
900 kWh per month ÷ 30 = 30 kWh per day
30 × $0.18 = $5.40 per day
How to Reduce Daily Electricity Costs
- Lower thermostat by 1–2 degrees
- Switch to LED lighting
- Use smart thermostats
- Unplug phantom loads
- Improve insulation
Small changes can reduce daily costs by 10–20%.
