Input the total electricity usage in kilowatt-hours (kWh).
Example: 350 units
Step 2: Enter Rate per Unit
Enter the cost charged by your electricity provider per unit.
Example: $0.15 per kWh
Step 3: Enter Fixed Charges
Add any fixed monthly charges such as meter rent, service tax, or connection fees.
Example: $10

Formula Used in Electric Bill Calculation
The calculator uses a simple and widely used billing formula:
1. Energy Cost
Energy Cost = Units Consumed × Rate per Unit
2. Total Bill
Total Bill = Energy Cost + Fixed Charges
Example Formula Breakdown:
If:
- Units = 500 kWh
- Rate per Unit = $0.20
- Fixed Charges = $15
Then:
Energy Cost = 500 × 0.20 = $100
Total Bill = $100 + $15 = $115
Example Electricity Bill Table
| Units Consumed (kWh) | Rate per Unit ($) | Fixed Charges ($) | Energy Cost ($) | Total Bill ($) |
|---|---|---|---|---|
| 100 | 0.12 | 5 | 12 | 17 |
| 200 | 0.15 | 8 | 30 | 38 |
| 300 | 0.18 | 10 | 54 | 64 |
| 500 | 0.20 | 15 | 100 | 115 |
| 750 | 0.22 | 20 | 165 | 185 |
