Line-by-line estimate for 400 units
For an un-protected home with 1 kW sanctioned load, the 400-unit bill builds up like this on September 2026 bills. Each row is one line of the bill; the fuel adjustment is applied to the same 400 units for simplicity.

Which slab do 400 units fall in?
400 units fall in the 301 to 400 unit slab: Rs 36.46 a unit and a fixed charge of Rs 400 per kW for an un-protected home. Un-protected homes pay one rate on every unit of the month, set by the slab the total falls in.
There is no protected rate above 200 units. A 400-unit month is billed at un-protected rates, and a home that was protected loses that status until it has six months in a row at 200 units or less.
How close is 400 to the next slab?
400 units is the top of the 301 to 400 slab, so one more unit moves the whole month to Rs 38.95 a unit. For a 1 kW un-protected home, 401 units would cost about Rs 1,370 more than 400.

What else changes a 400-unit bill?
Your sanctioned load, the month the fuel adjustment was based on, and any arrears can all move the bill away from this estimate.
- Sanctioned load. The fixed charge is Rs 400 for each kW at this slab, so a 2 kW home pays about Rs 21,167 in all. See MEPCO fixed charges per kW.
- The fuel adjustment. It is charged on the units of an earlier month, not this one. This month's rate is on MEPCO fuel and quarterly adjustments.
- The debt servicing surcharge. Rs 3.23 a unit for un-protected homes and Rs 0.43 for protected ones, under NEPRA's decision of 30 March 2023.
- Arrears and late payment. Unpaid amounts from earlier bills and the late payment surcharge are not in this estimate.
