How the bill is calculated
The math behind the estimate
Total Bill = (Units Consumed × Rate per Unit) + Fixed Charges. For example, 350 units at a rate of 22 with 150 fixed charges gives 350 × 22 + 150 = 7,850.

Accuracy & limitations
This calculator is built for speed and accuracy, but it's worth understanding what it does and doesn't account for:
- No tiered/slab pricing. Some providers charge different rates per usage bracket — this tool applies one flat rate to all units.
- Taxes not included. Some providers add taxes or surcharges separately from the per-unit rate — check your actual bill for these.
- Manual rate entry. This tool doesn’t know your provider’s current rate automatically — enter it from your latest bill.
