Electricity Bill Calculator

Estimate an electricity bill from units (kWh) and a tariff you enter — NEA slabs change, so the rate is yours to confirm.

How it's calculated

Amount ≈ kWh × rate (+ any fixed charge field the handler exposes). Slab stacking only if those fields exist.

Example

Inputs

  • Units: 200
  • Rate Per Unit: 12
  • Fixed Charge: 100

Outputs

About this calculator

Bills in Nepal are slab-based and ampere-based in ways a single rate cannot fully capture. This calculator estimates from the kWh and tariff inputs you provide so a 2°C AC change can be seen in rupees, not in folklore.

Always check the latest Nepal Electricity Authority tariff card for your consumer class (5A vs 15A, household vs commercial). Time-of-day, minimum charges, and demand charges may sit outside this form.

Frequently Asked Questions

Energy charge = kWh × rate per unit; total = energy + fixed charge. Default 200 units, 12 per unit, 100 fixed — placeholders. Paste your NEA/community tariff slab, not this default.
No. It is a single rate × units. Nepal domestic slabs are progressive; for true NEA bills, split units by slab yourself or expect a mismatch.
This is energy kWh × NPR/kWh. Time-of-day or kVAh commercial tariffs are not modelled.
Not modelled. Prepaid deducts from a token; this is a post-paid-style multiply.
Only if you fold them into “fixed charge.” Otherwise add outside.
Same arithmetic. Demand (kVA) charges are extra for some commercial meters.
Not a net-meter engine. Enter import units the bill shows, or net if that is what you are modelling.
Not included.
Slabs, minimum charge, rebates and extra levies. Use this when you have an agreed single NPR/kWh (e.g. a simple backup meter).
No — form default. Read the current NEA consumer tariff schedule.
