Whether you want to know how to calculate electricity bill manually or use an EB bill calculator online, this step-by-step guide will help you understand your power usage and even save money!
How to Check and Calculate EB Bill?
Step 1: Know What is in Your EB Bill
Think of your EB bill like a restaurant bill. You pay for what you eat (units consumed), a service charge (fixed charge), and sometimes, extra items like a cold drink (taxes and additional charges). Here’s what you need to know:
- Energy Charge – Based on how many units (kWh) you use.
- Fixed Charge – A fixed amount for your power connection.
- Tariff Slabs – Just like a buffet, the more you take, the higher the charge.
- Taxes and Extra Charges – Government charges added to your bill.
Step 2: Check Your Meter Reading
Checking your meter is like weighing yourself before and after a feast.
- Look at your electricity meter for the latest reading.
- Check last month’s reading from your old bill.
- Subtract the old reading from the new reading to find how many units you used.
Example:
- New Reading: 1050 kWh
- Old Reading: 950 kWh
- Units Used = 1050 – 950 = 100 kWh
Now, let’s see how much this meal (electricity) will cost!
Step 3: Find Your EB Tariff Rate
Electricity charges in Tamil Nadu change based on how much you use. Imagine you’re buying vegetables—1kg of tomatoes is cheap, but buying 10kg might cost more per kg. Here’s an example:
- First → 100 = ₹0
- Upto 400 units →101- 400 = ₹4.80
- Next 400 to 500 units →401 – 500 = ₹6.45
- Next 500 to 600 units →501 – 600 = ₹8.55
Step 4: Calculate Your EB Bill
Let’s say you used 550 units:
First 100 units → 0 = ₹0
Next 101- 400 → 300 × ₹4.8 = ₹1440
Next 401-500 units → 100 × ₹6.45 = ₹645
Last 50 units → 50 × ₹8.15 = ₹407.5
Total Energy charges = ₹ 2492.5
Now, add fixed charges and taxes (just like GST at a restaurant) to get the final bill amount.
