Planning estimateHow this calculator helps
Enter the electricity units consumed during the month to receive a transparent planning estimate. The result separates estimated energy charges from adjustable taxes and surcharges so you can understand the assumptions.
How to use it
- 1
Copy the units consumed from your meter or latest bill.
- 2
Enter an average energy rate and the additional-charge percentage shown on your bill.
- 3
Review energy charges separately from the estimated taxes and surcharges.
Formula and methodology
Estimated bill = slab-based energy charges + configurable taxes and surcharges. Actual DISCO bills may include FCA, QTR adjustments, TV fee and other provider charges.
Worked calculation example
If a household uses 250 units, the calculator applies each configured slab to the relevant portion rather than multiplying all units by a single rate.
What can affect the result?
Tariff category
Residential, commercial and protected-consumer tariffs can be calculated differently.
Billing adjustments
Fuel and quarterly adjustments may change from one billing period to another.
Meter period
A longer or shorter meter-reading cycle changes total units even if daily use is stable.
Limits of this estimate
This simplified planner does not reproduce every DISCO slab, protected-status rule, minimum charge or time-varying government adjustment.
