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 Electricity Bills Are Calculated in Pakistan
Understand units, slabs, protected status, taxes and adjustments before estimating a Pakistan electricity bill.
Read the complete guide →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.
Applies configured consumption slabs to the relevant units, then adds editable taxes and adjustments. It is checked against the worked example and should be compared with a recent bill.
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.
How to interpret your result
Use the estimate to explain which part of consumption is driving the bill, then compare it with the energy-charge section of a current DISCO bill.
Input guide
Units must come from the billed period, not a daily meter reading.
Use a blended rate only for a quick comparison; progressive slabs are more accurate.
Add FCA, taxes and adjustments separately when they appear on the bill.
Scenario comparison
| Scenario | What it demonstrates |
|---|---|
| 100 units | tests a low-consumption household before variable adjustments. |
| 300 units | shows how crossing consumption bands can change the effective rate. |
| 500 units | makes taxes, FCA and upper-band charges more significant. |
Common mistakes to avoid
- Multiplying every unit by the highest slab rate.
- Comparing protected and non-protected bills as if their treatment were identical.
- Ignoring billing days, arrears, TV fee or quarterly adjustments.
Compare the breakdown with the tariff schedule and a recent bill from the correct distribution company.
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.
