How APDCL Electricity Bills are Calculated

Understanding your APDCL monthly bill is easy when you know the slab system used by the Assam Power Distribution Company Limited. The bill consists of multiple components including Energy Charges (based on units consumed), Fixed Charges (based on connected load), Fuel Surcharge, and Electricity Duty.

For domestic consumers in Assam, the rates change as your consumption increases. Staying within the first 100 units is the most cost-effective way to manage your electricity expenses. Our online bill estimator uses the latest 2026 tariff structures to give you a near-accurate figure before your official bill arrives.

  • Lower Slabs: Units from 0 to 100 are charged at the most subsidized rate.
  • Fixed Charges: These are mandatory monthly charges based on your sanctioned load (kW).
  • Electricity Duty: A government tax applied as a percentage of your total energy consumption.
What is the per unit rate of APDCL in 2026?

As of 2026, the domestic per unit rate starts at ₹3.90 for the first 100 units. The rate increases to ₹5.10 for the next 100 units, and continues to rise for higher consumption categories.

Can I calculate my bill manually?

Yes, by multiplying your unit consumption in each slab by the corresponding rate, adding the fixed charges, and then calculating the electricity duty. However, using our APDCL bill calculator is much faster and reduces the chance of errors.

Why is my APDCL bill so high?

Bills often increase due to seasonal use of high-power appliances like ACs or heaters, which pushes your consumption into higher price slabs. Check our "Tips to Save" section to learn how to keep your usage in lower slabs.
