Can you believe that money spent on Induction stove power is far less than that spent on cooking with the Gas stove? You can save up to INR 30,000 annually just by switching to an induction cooker.
Induction Stove vs Gas Stove: Consumers are utilizing Induction Stove Power as it vies with older peer – Gas Stove, for saving money while cooking. If we compare Induction Cooker Electricity Consumption, it is economical than what we spend in comparison to cooking through LPG/PNG gas stoves. Subsequently, to a large extent, it will impact the overall economy of the country also in its segment.
Induction Cooker for Atamnirbhar Bharat
Front runners of our industries and people of India are sincerely looking forward to self-reliance. The Government should work for shifting the manufacturing base of Induction cookers to our country and make the availability of products cheaper and accessible to masses on a fast track.
But Why…….
To justify what I am saying and to have a better understanding, I have divided this context into four broad divisions.
- First, understanding the LPG trends in India
- Second, we will study a cost comparison of LPG and Induction stove power while cooking
- Third, we will compare the saving in different states of the country
- Finally, the conclusion
Trends in LPG cooking
Liquefied Petroleum Gas (LPG) is a petroleum by-product. As per 2010 census, the following was the breakup of fuel used for cooking by 24.67 cr households in India
- 0.3% don’t cook
- 49% used firewood, 8.9% used crop residue, 8.0% used Cow-dung cakes, 0.4% used bio-gas
- 1.5% used coal, charcoal and lignite.
- 2.9% used Kerosene.
- 28.6% used LPG/ PNG
- 0.1% used electricity
- 0.5% used other sources
As per statistics, in the year 2018-2019, India consumed close to 25 million tonnes of LPG. This is claimed to be 52% higher than what it was in the year 2013. The credit for this rise goes to the PM Ujjwala scheme launched in 2016. As per government data, households in 714 districts benefited by 72 million new connections. Now the problem is, grown LPG connection has sparked India’s import of LPG. 13 million tonnes of LPG was imported in the year to March 2019 and has further grown.
As per a research analyst at Wood Mackenzie, Aman Verma, the phenomenal growth in LPG usage will reduce India’s self-sufficiency of LPG to 42% in 2025 from about 70% in 2013. The other cheaper option of gas is also available in form of PNG. Click to know the difference between LPG and PNG
All said and done, but the question is, how do – I save money by using induction stove power
Now we shall further study an apple-to-apple comparison of energy consumed through LPG combustion and energy consumed utilizing Induction stove power for cooking. There is no direct simple formula to compare spending on both products. So some units need to be converted to bring both the products on the same platform for comparison.
As per Electric Power Research Institute, Sacramento, CA, on average 90% of converted energy is transferred to food in case of Induction cooking whereas only 40% is transferred in case of Gas in a controlled environment.
| Types of Burner on Gas Stove | Gas power (in BTU/hr) | Electric Power (in Watts) |
|---|---|---|
| Small | 5000 | 800 |
| Medium | 9000 | 1400 |
| Large | 12000 | 1900 |
| Extra- Large | 15000 | 2400 |
| Commercial | >= 18000 | >=2900 |
For calculation purposes, I am taking into account – Large burner of LPG Stove and its equivalent 8″ coil of Induction stove with a power rating of 2000 watts. Once understood the calculations, readers may experiment with other burner types in the stove and their equivalent power in the induction cooker.
Time for Cooking (Induction Stove vs Gas Stove):
This is extremely important to know through the proven fact that due to high efficiency, the Induction cooker takes almost half the time to heat the same object of the same quantity to the same temperature in the same vessel than a gas stove. One such example is beautifully crafted by Dean Sharp in his video
Let’s get down to calculations
A) Cost of cooking on LPG
- Indian households use standard LPG cylinders which weighs 14.2 Kgs that have 659.6KBTU.
- If a unit cylinder costs rupees ‘x’. 1KBTU will cost x/659.6.
- A large burner taken in our calculation consumes 12 KBTU in an hour (refer table above).
- So in an hour of cooking on the large burner will cost us Rupees (x/659.6)*12 or .018x
B) Cost of cooking on Induction Cooker
- 8”, 2KW induction cooker consumes 2 units per 60 mins.
- If we are using an induction cooker for the same purpose as heating the same stuff as in point A above, it will accomplish the task in 34 mins. So if we calculate, 1.13 units are used.
- We need to take into account the per unit charge at the point of consumption and multiply it with 1.13 to calculate the cost.
Both the costs are not static and vary from state to state within a region. To better understand the Induction Cooktop vs Gas Cost in India. Let’s take examples of two different states and calculate the cost to have a better understanding of savings
Case Study of cost-saving for people of Punjab
Cost of non- subsidized LPG per household
- The landing cost of the LPG cylinder (Average of Jan ’20, Feb’20, and Mar’20)= Rs. 841.75
- Consumption per hour= Rs. 15.31 (refer formula above => 0.018x)
- If a household is using LPG for cooking for 4 hours per day for 30 days, the total cost to customers is Rs. 1818 per month.
Cost of using Induction stove power for same usage as LPG per household
| Slabs on basis of unit consumption | 0 to 30 | 31 to 50 | 51 to 100 | 101 to 300 | 301 to 500 | > 500 |
|---|---|---|---|---|---|---|
| Slab-wise household consumption (%) | 9 | 14 | 34 | 37 | 5 | 1 |
| Slab-wise per unit rate ( in Indian Rs.) | 4.99 | 4.99 | 4.99 | 6.59 | 7.2 | 7.41 |
If a household switches itself to induction cooking. For 30 days it will start consuming extra electricity
34 mins is converted to 0.57 hrs.
Total number of hours per day equivalent to 4 hours of LPG usage =0.57*4 = 2.27 hrs/day
For 30 days = 68 hrs/ month
Consumption of induction stove power in month @ 2KwH= 68 x 2 =135.5 Kwh
Once a customer starts using induction cooker he will be pushed to next slabs in some cases so final consumption patter will come out to be
| Slabs on basis of unit consumption | 0 to 30 | 31 to 50 | 51 to 100 | 101 to 300 | 301 to 500 | > 500 |
|---|---|---|---|---|---|---|
| Slab-wise household consumption (%) | 9 | 14 | 34 | 37 | 5 | 1 |
| Slab-wise per unit rate ( in Indian Rs.) | 6.59 | 6.59 | 6.59 | 7.2 | 7.41 | 7.41 |
Weighted average for state comes out to be 6.86 units per household
The variable charges thus calculated as:
- Rate=Rs.6.86/ unit
- Units consumed by Induction in 34 mins=1.13 units
- Equivalent to 4 hrs a day as in case of gas= 4 times a day
- Total variable charges= 6.86 x 1.13 x 4 x 30 =Rs. 930 per month
There is also a fixed charge in the state on the basis of the sanctioned load. If we take it as 3KW an additional Rs. 135 is charged by the electricity board. If we assume there are 5 products in the house that take a heavy load, induction will take a pie of Rs. 27 in fixed cost
Hence total charges for Induction stove electricity consumption comes out to be
=> 930 + 27 = Rs. 957 per month
Case Study of cost-saving for people of Tamil Nadu
Cost of non- subsidized LPG per household
- The landing cost of the LPG cylinder (Average of Jan ’20, Feb’20, and Mar’20)= Rs. 832.5
- Consumption per hour= Rs. 15.14 (refer formula above => 0.018x)
- If a household is using LPG for cooking for 4 hours per day for 30 days, the total cost to customers is Rs. 1817 per month.
Cost of using Induction stove power for same usage as LPG per household
| Slabs on basis of unit consumption | 0 to 30 | 31 to 50 | 51 to 100 | 101 to 300 | 301 to 500 | > 500 |
|---|---|---|---|---|---|---|
| Slab-wise household consumption (%) | 14 | 19 | 34 | 30 | 2 | 1 |
| Slab-wise per unit rate ( in Indian Rs.) | 0 | 0 | 0 | 3.5 | 4.6 | 6.6 |
If a household switches itself to induction cooking. For 30 days it will start consuming extra electricity
34 mins is converted to 0.57 hrs.
Total number of hours per day equivalent to 4 hours of LPG usage =0.57*4 = 2.27 hrs/day
For 30 days = 68 hrs/ month
Consumption of Induction stove power in month @ 2KwH= 68 x 2 =135.5 Kwh
Once a customer starts using induction cooker he will be pushed to next slabs in some cases so final consumption patter will come out to be
| Slabs on basis of unit consumption | 0 to 30 | 31 to 50 | 51 to 100 | 101 to 300 | 301 to 500 | > 500 |
|---|---|---|---|---|---|---|
| Slab-wise household consumption (%) | 14 | 19 | 34 | 30 | 2 | 1 |
| Slab-wise per unit rate ( in Indian Rs.) | 3.5 | 3.5 | 3.5 | 4.6 | 6.6 | 6.6 |
Weighted average for state comes out to be 3.92 units per household
The variable charges thus calculated as:
- Rate=Rs. 3.92/ unit
- Units consumed by Induction in 34 mins=1.13 units
- Equivalent to 4 hrs a day as in case of gas= 4 times a day
- Total variable charges= 3.92 x 1.13 x 4 x 30 =Rs. 532 per month
There is also a fixed charge in the state. Considering, bimonthly slab of 501 and above plus assuming 1 service on basis of sanctioned load, additional Rs.20 is charged by electricity board. If we assume there are 5 products in house that take heavy load, induction will take a pie of Rs. 4 in fixed cost.
Hence total charges for Induction stove electricity consumption comes out to be
=> 532 + 4 = Rs. 536 per month

Let’s recollect and summarise the assumption in the calculation:
- Rate of LPG cylinder is taken as an average for months of Jan ’20, Feb’20, and Mar’20 in respective states. The price for standard 14.2 kg LPG CYLINDER is taken.
- The calculation is based on a large burner with 12KBTU/HR. this makes a total of 1440 kBtu per month and this implies we require 2.1 cylinders that don’t qualify for the subsidiary. But even if we consider subsidiary and deduct Rs. 250 from the pricing of LPG on the contrary, the induction cooker is still an economical choice.
- The highest slabs of electricity are considered, No subsidies considered while calculating the Induction stove electricity consumption
How to use the induction stove
Conclusion
Not much to make you understand what is economical
- Benefits for Individual: As evident from the table above, an average Indian household may save around Rs. 5000- Rs. 30000 annually just by switching the cooking habits from conventional gas cooktops to Induction cookers. This is like investing in money market funds but with Zero risks.
2. Benefits for Nation: There are approx. 25 crore households in India, even if 15% of these households switch their cooking habits to an induction cooker, it will help to induce 50k crores in the Indian economy annually. For such a huge demand, this industry can grow to 11k cr with almost 1.5 sets per household. In addition to this, in times when induction cookers will be produced locally, it will certainly boost employment for such a big industry. This will further help in “Atamnirbhar Bharat Abhiyaan”
Analyzing the top 10 states where the ratio of cost of LPG is comparatively higher than that of Induction stove electricity consumption, 8 states are the hilly or remote states. The scope of converting customers in these states is highest as compared to other parts. So organizations promoting Induction Cookers should not miss this opportunity. More and more companies can seek this opportunity.
“Manufacture this Gold on Indian Soil and earn like never before.”
The scope of principle of Induction has gone beyond stoves to other appliances like electric kettles.
Frequently Asked Questions
One most common question people ask in Hindi regarding Induction stove electricity consumption is: “Bijli zyada lagti hogi? Baat to vahin aa jaati hogi?” (It would consume more electricity. So cost wise there would be no difference) has been well answered with examples and the difference shown. So Induction Stove Power, in all ways, is a cheaper option to use in cooking.
