Frequently Asked Questions
Q:How do progressive electricity slabs work in India?
Most Indian state electricity boards (DISCOMs) use telescopic billing slabs. As your monthly consumption increases, units exceeding earlier thresholds are billed at significantly higher tariff rates. Crossing into the 400+ unit bracket can push your unit rate from ₹4.50 to ₹10.00+, which is why reducing even 30–50 units can result in dramatic bill savings.
Q:What are fixed demand charges on my electricity bill?
Fixed charges are monthly connection capacity fees billed per kilowatt (kW) of sanctioned load regardless of whether you consume any power. For example, in Maharashtra, MSEDCL charges ₹115 per kW monthly. A 3 kW connection pays ₹345 monthly in fixed charges before using a single unit.
Q:Can I calculate the electricity bill for a shared apartment or PG?
Yes! You can customize your exact appliances (fan, laptop, personal cooler, mini-fridge) and daily hours to calculate your personal sub-meter consumption and monthly financial share.
Q:How does TANGEDCO calculate electricity bills in Tamil Nadu?
TANGEDCO (Tamil Nadu Generation and Distribution Corporation) uses a telescopic slab system for domestic consumers. The first 100 units per month are free under the subsidy scheme. Units 101–200 are billed at ₹1.50/unit, 201–500 at ₹3.00/unit, and above 500 at ₹5.75/unit. A fixed charge of ₹25–₹60 per month also applies based on sanctioned load. Our calculator models this exact structure.
Q:What is Fuel Adjustment Charge (FAC) on my electricity bill?
The Fuel Adjustment Charge (FAC), also called Fuel and Power Purchase Cost Adjustment (FPPCA), is a variable pass-through charge added when a DISCOM's actual fuel and power purchase costs exceed the base tariff. It can add ₹0.25 to ₹1.50 per unit to your bill depending on global energy prices and the billing quarter. It is separate from the fixed tariff slab rate.
