Formula & Methodology
The formula to calculate your electric usage is:
Usage (kWh) = (Current Reading - Previous Reading) / (Days in Billing Period)
Real-World Examples
Example 1: If your current reading is 12345 kWh, previous reading is 11234 kWh, and your billing period is 30 days, your usage would be:
(12345 - 11234) / 30 = 36.83 kWh/day
Example 2: If your current reading is 56789 kWh, previous reading is 55678 kWh, and your billing period is 31 days, your usage would be:
(56789 - 55678) / 31 = 36.73 kWh/day
Example 3: If your current reading is 98765 kWh, previous reading is 97654 kWh, and your billing period is 28 days, your usage would be:
(98765 - 97654) / 28 = 40.45 kWh/day
