Estimates based on NEPRA domestic tariff FY2024-25. Enter current FAC from your DISCO's monthly notification for a more accurate total. Meter rent and some provincial levies are excluded. Actual bill may vary by ±10–15%.

Above 200 units, a progressive rate applies where each 100-unit slab has its own rate. Surcharges and GST are then applied to the subtotal.
Pakistan's slab-based electricity tariff means small changes in consumption can cause large changes in your bill — especially when crossing the 200-unit protected threshold or the 300/400-unit high-usage slabs during summer. This calculator uses NEPRA's current domestic tariff to show you the complete bill breakdown: energy charges by slab, fixed charges, NJ surcharge, and GST.
Enter your monthly units consumed (from your meter or last bill), select your DISCO/utility, and choose your connection load. The calculator applies the correct rate for each unit, adds all surcharges and taxes, and shows your estimated total alongside the average cost per unit — which is always higher than the slab rate due to fixed charges and taxes.
A household using 350 units in a month on a standard 5 kW residential connection, no FAC entered. Crossing 200 units moves the extra units into the progressive slabs.
Estimated bill ≈ Rs. 6,090 — an average of about Rs. 17.4 per unit.
The average per-unit cost (Rs. 17.4) is well above any single slab rate because fixed charges and taxes are spread across every unit. Add your DISCO's monthly FAC for the real total.
The same 5 kW connection running air conditioning, using 600 units. Each additional 100-unit band is charged at a higher rate.
Estimated bill ≈ Rs. 12,568 — an average of about Rs. 20.9 per unit.
Going from 350 to 600 units roughly doubles the bill: the marginal units cost Rs. 21–23 each before tax.
Use this to plan energy conservation: the calculator makes it obvious exactly how much you save by reducing consumption from 350 to 280 units (crossing into a cheaper slab). You can also compare the cost impact before adding a new appliance or changing to a time-of-use meter.
People often compare the 'rate per unit' from the tariff schedule to their actual bill and wonder why it doesn't match. The average cost per unit in the real bill is always higher because fixed charges and taxes (roughly Rs. 400–800/month regardless of consumption) are spread across all units. Also, FAC charges can significantly change the final bill each month.
