Assam bill — quick answers
Is APDCL tariff really this low?
Yes — Assam benefits from hydel generation from the north-east's rivers; its slabs sit near the national minimum.
My APDCL bill shows extra charges — why?
Besides the lines we model, occasional charges like service/penalty appear. Our estimate covers the core five lines exactly as billed.

Assam electricity bill calculator — how your bijli bill is built
APDCL serves all of Assam with a domestic tariff of ₹4.25 (0–120), ₹6.30 (121–240), ₹7.20 (241–300), ₹7.40 (301–500) and ₹8.19 (501+) per unit, a ₹20/kW monthly fixed charge and ₹0.10/unit FAC.
Guwahati to Dibrugarh shares one AERC ladder, with the Jeevan Dhara lifeline category (≤0.5 kW connections) keeping reduced rates of ₹3.35/unit plus a ₹40/month fixed charge.
Example: your Assam bill for 250 units
Take a Assam household using 250 units in one month on APDCL. The telescopic energy charge is 120 × ₹4.25 + 120 × ₹6.3 + 10 × ₹7.2 = ₹1338.00. Add the fixed charge (₹40.00), FAC (₹25.00) — that gives a gross bill of ₹1403.00. With no subsidy in this state, ₹1403.00 is your payable.
Here is the same 250 units across every DISCOM in Assam — useful when your board's name differs from the common one:
| DISCOM | Energy | Fixed | FAC | Duty | Subsidy | Total |
|---|---|---|---|---|---|---|
| APDCL | ₹1338.00 | ₹40.00 | ₹25.00 | ₹0.00 | — | ₹1403.00 |
Does Assam offer a free-unit scheme?
Assam currently bills without a domestic free-unit subsidy, so the calculator's checkbox stays off and no green deduction line appears. That is tariff design, not an error — the energy charge is collected in full and the fixed charge, FAC and duty apply on top. If the state announces a scheme, we add it to the data and the toggle lights up automatically.
Assam tariff details — live data
The table below is generated from the same data the calculator uses, so what you see here is exactly what is charged. Looking for the per-unit electricity price in The slab column IS your per-unit rate — each rate applies only to the units inside its own slab range.
| DISCOM | Slabs | Fixed charge | FAC |
|---|---|---|---|
| APDCL | 1–120 @ ₹4.25, 121–240 @ ₹6.3, 241–300 @ ₹7.2, 301–500 @ ₹7.4, 501–above 501 @ ₹8.19 | ₹20/kW load | ₹0.1/unit |
Remember: in telescopic billing each slab rate applies only to the units inside its range. Many websites multiply one rate by total units — that is wrong and overstates bills. This calculator, like your DISCOM, adds slab by slab.
4 practical ways to lower your Assam bill
- The first 120 units at ₹4.25 keep base bills reasonable — LED and efficient fans protect it.
- Assam's humid climate makes the fridge and AC the load kings; 26°C saves units.
- Winter heating in the hills is brief — room-wise bursts beat all-night heaters.
- Verify each bill with the reading mode; monsoons swing usage month to month.
