Formula Used in Electricity Bill Calculation
The calculator uses a simple and widely accepted formula used by utility companies.
1. Energy Cost Formula
Energy Cost = Units Consumed × Rate per Unit
2. Total Electricity Bill Formula
Total Bill = Energy Cost + Fixed Charges
Example Formula Breakdown:
If:
- Units = 400 kWh
- Rate per unit = $0.25
- Fixed charges = $20
Then:
Energy Cost = 400 × 0.25 = $100
Total Bill = 100 + 20 = $120
Electricity Bill Calculation Table Example
| Units Consumed (kWh) | Rate per Unit ($) | Fixed Charges ($) | Energy Cost ($) | Total Bill ($) |
|---|---|---|---|---|
| 100 | 0.20 | 10 | 20 | 30 |
| 200 | 0.25 | 15 | 50 | 65 |
| 300 | 0.18 | 12 | 54 | 66 |
| 400 | 0.22 | 20 | 88 | 108 |
| 500 | 0.30 | 25 | 150 | 175 |
