Energy Saving Tips

Use LED Bulbs

Replace incandescent bulbs with LED bulbs to save up to 80% on lighting costs. LEDs last longer and consume significantly less power.

Switch to Solar

Consider installing solar panels to reduce your electricity bills. Government subsidies are available for residential solar installations.

Maintain AC Temperature

Set your AC to 24-25°C for optimal cooling and energy efficiency. Every degree lower increases power consumption by 6%.

Unplug Idle Appliances

Many household devices consume standby power even when not in use. Unplug chargers, televisions, microwaves, and other appliances to reduce unnecessary electricity wastage and lower your monthly bill.

Use Energy-Efficient Appliances

Choose appliances with a high BEE star rating for maximum energy savings. Refrigerators, air conditioners, and washing machines with 4-star or 5-star labels consume significantly less electricity and reduce long-term costs.

What Are Slabs in Electricity Billing?

Electricity charges are calculated using slabs. A slab is a range of electricity units with a fixed rate. For example:

UnitsRate per kWh
Note

The more units you consume, the higher the slab rates may apply. This calculator uses telescopic calculation, meaning each slab is charged only for units within that range.

Example: How Electricity Bill Estimation Works

Let’s look at a typical example to see how the bill is calculated for 250 units in a month.

1. Energy Charges (Slab Logic):

First 100 units @@ ₹4.00 = ₹400

Next 100 units @@ ₹6.00 = ₹600

Remaining 50 units @@ ₹8.00 = ₹400

Total Energy Charge: ₹1,400

2. Fixed Charges, Meter Rent & Duty:

Fixed Charge: ₹100 per month

Meter Rent: ₹50 per month

Electricity Duty at 5% of energy charges = ₹70

Total Estimated Bill: ₹1,620

Note: This is a simplified example. Actual rates, fixed charges, and taxes vary by state and connection type.

Frequently Asked Questions

How is the electricity bill estimate calculated?
The estimate is calculated by multiplying your consumed units with the applicable slab rates for your state and connection type, then adding fixed charges, meter rent, and electricity duty.
What is 1 unit of electricity?
One unit of electricity is equal to 1 kilowatt-hour (kWh). It is the amount of energy consumed by a 1,000-watt appliance running for one hour.
Why might my actual bill differ from the estimate?
Actual bills may include additional surcharges, variations in fuel adjustment charges (FAC), subsidies, or late payment fees that vary based on specific utility company rules.
Is this calculator accurate?
Yes, we use the latest available tariff data from state electricity boards. However, it should be used for estimation purposes as final billing is done by your provider.
Can this calculator be used for business connections?
Yes, you can select the "Commercial" connection type to estimate bills for shops, offices, or small businesses.
Why does slab rate affect the bill?
Electricity boards use slabs to encourage energy conservation; the more you consume, the higher the rate per unit for additional consumption levels.
