To calculate your gas bill, find the difference between your current and previous meter readings (in cubic meters/feet), then multiply that volume by the local heating value and pressure correction factor (often provided by your supplier) to get your energy usage in megajoules (MJ) or units, and finally multiply that by your tariff rate (cost per unit/MJ) and add daily supply charges and taxes.
Steps to calculate your IGL bill
Current meter reading is the number that shows on the front of your meter, recorded by the field agent who reads the meter. Each movement of the dial represents one cubic meter of gas used. Energy units used is calculated based on your current and last readings, converted into energy units.
How to work out gas consumption manually
Formula: Electricity Cost = Electricity Consumption (kWh) x Tariff Rate per unit. For example, if your previous meter reading was 1200 kWh and your current reading is 1400 kWh, your energy consumption is 200 kWh (1400–1200). If the tariff rate is ₹6 per kWh, your total energy consumption cost is ₹200x6 = ₹1200.
To estimate individual appliance usage, find the appliance's power rating (in W) and convert it to kW (divide it by 1,000). Then multiply the result by the hours of use per day and by the days of the month. For example, this is the calculation for a 0.1 kW TV used 4 hours a day: 0.1 kW × 4 h × 30 days = 12 kWh/month.
Multiply the m3 figure by a conversion factor of 1.02264, then by the calorific value. Calorific values vary; you should find this on your bill. Divide this figure by 3.6 to show your usage in kWh. Multiply your usage in kWh by your unit prices to work out your gas charge.
It's typically used to determine how much energy a household has consumed over a period of time. A kWh is the standard unit used by energy suppliers to calculate your gas and electricity bill. One unit of electricity or gas refers to the use of 1,000 watts over one hour.
Total cost per unit is how much it costs to produce a single item, receive new inventory, store it, and fulfill and ship it. Cost per unit is calculated using the formula: (Total fixed costs + Total variable costs) / Total units produced.
The average utility bill in the U.S. is $610 per month. Electricity is typically the most expensive component.
In general, heaters and water heaters use the most gas, with cooking appliances and clothes dryers making up a much smaller percentage. However, there are plenty of ways you can save energy in your home and reduce natural gas consumption without sacrificing comfort.
Here are some quick and easy actions you can take to reduce your energy usage and therefore your bills:
For example, if you'll be driving an average of 60 miles per hour and your car gets 25 miles per gallon, you'll need about 2.4 gallons of gas for your trip. If the cost of gas is $3.04 per gallon, your hour-long trip will cost $7.30.
Computing Your Natural Gas Therm Usage
* Subtract your previous meter reading from your present meter reading. * Multiply the difference by the multifactor shown for your meter and round to the nearest whole number. (This is your natural gas therm usage for the period.)
How do you calculate fuel cost per mile? You can find the fuel cost per mile by taking the current per-gallon price of gas and dividing it by your vehicle's miles per gallon.
In India, 1 unit of electricity is equivalent to the consumption of 1 kilowatt-hour (kWh) of electrical energy.

We estimate your average daily usage based on the meter reading data available, including your reading. We take into account temperature, seasonality, average usage of similar customers in your area. We then update this by the total number of days in the billing period.
How to calculate electricity bill amount manually
Residential customers in the United States used an average of 10,791 kilowatt-hours of electricity in 2022. This works out to roughly 899 kilowatt-hours per month, or about 30 kilowatt-hours per day.
Comparing Gas and Electric Heating
Firstly, gas is generally cheaper than electricity, so if you have access to a gas supply, it is likely to be the cheaper option. However, if you do not have access to a gas supply, electric heating may be your only option.
Depending on the model and efficiency, a one-ton AC uses about 1.2 kWh/hour, while a 1.5-ton AC uses around 1.5 kWh/hour. On average, running an AC for 8 hours a day can add anywhere from ₹1,800 to ₹3,500 per month to your electricity bill, depending on the AC type and your electricity rate.
