Electricity Bill Calculator

Estimate your electricity bill from units consumed. Works with a flat per-unit rate or slab-based tariffs (where the rate changes as you use more). Add fixed charges and electricity duty to get a realistic total.

Slab Rates
Enter upper limit and rate; leave last "Up to" empty for remaining units.

How to use

  1. Enter the number of units consumed (you'll find this on your electricity bill as kWh).
  2. Choose Simple mode for a flat rate, or Slab mode if your tariff changes based on usage.
  3. Add fixed charges and electricity duty if they apply.
  4. Click Calculate to see the estimated bill breakdown.
