Electricity bill calculator
Estimate your bill from units and your tariff slabs, plus fixed charges and taxes.
Estimate only — your DISCO bill is authoritative.
How it's calculated
Units are billed through progressive slabs at each slab's rate, then fixed charges and a combined tax percentage are added.
- Enter the slab rates from your latest bill or the current NEPRA-notified tariff
- Fuel price adjustments, TV fee and other line items vary by DISCO and month

Questions
Where do I find my slab rates?
Your bill lists the units and rate per slab, and NEPRA publishes notified tariffs. The example slabs pre-filled here are placeholders, not the current tariff — replace them with yours.
How are slabs applied?
Units fill each slab in order: the first slab's units at its rate, the next slab's units at its rate, and so on. If you use more units than your last capped slab, the extra units are charged at the last slab's rate.
Why is my real bill higher?
Bills can include fuel price adjustments, quarterly adjustments, TV fee, electricity duty and other items that change monthly. Add flat items under fixed charges and percentage items under taxes.
