By Lal Singh You must be hearing a lot about how fast India is growing and how we recently became the 4th largest economy in the world. Well, the thing is, that growth didn’t just come out of nowhere, nah, there are actual industries supporting this growth and making sure that India grows its economy even more in the foreseeable future. Though when talking about India’s economy, not a lot of people have a good idea of which industries actually contribute the most to the overall numbers. So if you don’t know that either, well, let’s just get on with this list of the Top 10 Major Industries in India 2025, and it’ll be all clear for you by the end.
1. Information Technology & Software Services
We could not have started this list with anything other than the Indian IT sector. Why exactly? Well, simply for the one single reason, and that being its contribution to the economy as one of the largest industries. The trend is maintained by the sector in 2025, which is still the biggest one in India, with IT exports reaching beyond $200 billion. India’s IT bigwigs and startups are the front-runners in the global digital transition, be it through cloud computing, AI services, or software exports. The major hubs such as Bengaluru, Hyderabad, and Pune continue to thrive with new ideas.
2. Manufacturing (Auto, Electronics, FMCG, Textiles)
Of course, recently, there is a push to make India one of the biggest manufacturers of things in the entire world, and we’re seeing the progress towards that, albeit slowly and steadily. The country uses this sector to produce a wide range of goods, from vehicles and tech gadgets to basic necessities and trendy items. As of 2025, manufacturing accounts for around 13.9% of India’s GDP, and the figure is going up only. If you factor in FMCG and textiles, it becomes absolutely obvious that it is not just a single sector but a full-blown industrial rhythm in itself.
3. Financial Services & Real Estate
Finance is the industry that comes in the #3 position and is the one that affects every Indian either directly or indirectly. With a little over 22% share of the Indian economy, it is not just the banks and the stock market that are the game anymore. This sector has been the center of attention due to the rise of middle-class income, expanding cities, and a boom in digital financial tools.
4. Healthcare & Pharmaceuticals
Surely, you are aware that India is among the leading vaccine manufacturers in the world. But the thing is, or the question is, what remains after the pharmaceutical exports in the healthcare sector in 2025? The answer is access, infrastructure, and innovation. There has been an increase in the reach of hospitals and diagnostic centers in the areas of semi-urban and rural zones. After seeing the medical research and development and healthcare technology sector booming, one can only expect the demand curve to keep going up with the growing population.
5. Agriculture & Allied Sectors
So, one can argue that the agricultural sector in India is still very dominant, as it supports almost half of the total workforce in the country in 2025. Despite its decline, the sector that has been around for ages is still ranked at #5 and is, therefore, one of the biggest contributors to India’s GDP, providing close to 18% of the total economic output. With that said, another thing to know here is that India is still a global leader in crop production, ranging from rice and wheat to fruits, vegetables, dairy, and fisheries.
6. Construction & Infrastructure
It is the only industry, if any, that you can literally see expanding around you. Ranked at number six, the combined area of construction and real estate is the one that is not only figuratively but also quite literally making India’s future. With a range of infrastructural projects such as highways, metros, and smart cities, this industry accounts for around 8.75% of the total GDP. So major? Of course it is!
7. Automobile & Auto Components
The car sector is no longer just one of many sub-industries under the general manufacturing sector at #7, merely, the automobile industry has separated itself from the others. India has turned into one of the top vehicle manufacturers globally, and the country is sending out a full range of products that include two-wheelers as well as electric cars. One whole different ecosystem is there due to the rise of EVs and battery plants, and the auto components are going through a heavy export surge right now, which ultimately is a good thing.
8. Renewable Energy
Are you aware of the fact that India is a country that has 175 GW+ of renewable energy capacity? This alone makes the renewables sector the eighth most impactful industry in India. So no doubt, as of late, solar energy is the major contributor to this growth, with solar systems being set up in residential areas, industrial units, and agricultural fields. With significant government backing and considerable foreign investment, the renewable sector is expanding at a record pace.
9. E-Commerce & Retail
The manner in which people of India purchase goods nowadays is wildly different from their behavior just 5 years ago, or maybe a decade ago. With the position of number 9, e-commerce is among the rapidly changing sectors in India. Whatever you need, like fashion, food, and groceries, electronics, or even furniture, is just a click away now, quite literally! The reason is not only the convenience, but also the access, speed, and scale.
10. Telecommunications
At #10 in our lineup, we have the Indian telecom sector, which is very influential, and you must be aware of that too. India is one of the top digitally connected nations globally, thanks to the hundreds of millions of users and the fast deployment of 5G. Telecom has been the backbone of India’s digital revolution by providing the necessary infrastructure for digital banking and remote education. And, it is turning out to be a very good development for rural India also, as they have become a part of the network due to affordable smartphones, and at the same time, internet coverage is increasing further.
Conclusion
There you have it. See, it isn’t just a matter of which industry is growing the fastest; we talked only about the major industries, the ones that are contributing the most to the overall GDP numbers of India, year after year. And when you see or hear something about the GDP growth percentage, well, just know that the growth must have come from all of these industries combined.
