Introduction: One of my clients’ stories, Mr. Nikhil Sharma, is a 26-year-old Myntra employee from Jaipur. Recently, he shifted to a new 1 BHK Flat. Jaipur summers are no joke, and to beat the heat, he bought a new window air cooler rated at 250 watts.
He assumed the monthly electricity cost would be low and used it for almost 10 hours daily. But at the end of the month, he was shocked to see his electricity bill rise by over ₹1,000.
“All I did was add one cooler! How could the bill jump so much?” he asked.
Nikhil’s story is common. Most people don’t realise how quickly small appliances add up to significant electricity usage and cost when used for long hours.
That’s exactly why we created the Ease Electricity Bill Calculator – a simple tool that gives you full control over your monthly and yearly electricity estimates.
What Do You Mean by Electricity Bill?
The electricity bill, also known as the Bijli or light bill, is your monthly statement from the electricity provider in India. It contains power consumed and charges due, often including taxes, surcharges, subsidies, and fixed fees.
How It Works in India
In india, the electricity bill is a monthly charge based on the number of units (kWh) of electricity used by you. It is usually calculated by multiplying the number of units used by the per-unit rate specified by your state or city electricity board. Let’s break it down with additional costs:
- Your 1 unit of electricity is equal to 1 kilowatt-hour (kWh). In simple terms, it is using a 1000W appliance for 1 hour.
- Electricity Boards: Each Indian state has its own board department (for example, BSES, MSEB (Maharashtra ), TNEB for Tamil Nadu, DHBVN) with different slab rates.
- Slab System:
- 0–100 units: Low rate (often subsidised)
- 101–300 units: Moderate rate
- 301–500 units: Higher rate
- 500+ units: Highest rate
- Other Components: Fixed charges, meter rent, taxes, and fuel adjustment surcharge can also apply.

Knowing your usage in units is the key to controlling your bill.

What Formula Works for Calculating Manually?
If you decide to calculate your monthly light bill by a pen and a paper, here is the formula you can use with a real-life example in india –
- Monthly Units = (Watt × Hours per Day × Days × Quantity) ÷ 1000
- Monthly Cost = Monthly Units × Per Unit Rate
- Yearly Cost = Monthly Cost × 12
Here is an Example –
Let talk Nikhil’s Cooler example for better understanding:
- Power: 190 watts
- Usage: 10 hours/day
- Quantity: 1
- Days: 30
- Per Unit Rate: ₹7
Units: (190 × 10 × 30) ÷ 1000 = 57 units/month
Bill: 57 × ₹7 = ₹399/month Yearly: ₹399 × 12 = ₹4788/year
