Commerce is a multidisciplinary stream which encompasses the study of Law, Management, Accounting, Finance and Human Behaviour. Commerce education equips students with analytical, communication and problem-solving skills to effectively identify issues and find efficient and practical solutions to everyday business problems. Commerce graduates are employed in industries all over the world, including energy and resources, accounting, financial and insurance services, consulting, information management and marketing and communication. They also gain employment in the public sector in fields such as government administration, education and training, healthcare, transportation, etc.

The Department celebrated its Golden Jubilee in the year 2023, and the Department's Alumnae Association “Aikyam: The Gargi ComConnect” has also been constituted in June 2023, to maintain and nurture the connection of alumni with their alma mater. Aikyam, in Sanskrit, means 'unity' and perfectly captures the essence of this initiative. The Association is looking to create opportunities for Commerce alumnae of Gargi College to come and meet students through the year and share their expertise and knowledge with them. In this way, they can expand on their network and reconnect with their teachers. Current students of the Department can also benefit from alumnae’s experiences. Aikyam plans to host an Alumnae Meet every year. No matter where the students are today, their journey is an inspiration to us all and Aikyam celebrates it because the journey doesn't end at graduation; it's a connection that continues to thrive. Throughout the year 2023-24, the student team, under the Faculty Advisors - Dr. Sangeeta Jerath, Dr. Mandakini Das, Prof. Sonali Ahuja Dua, Ms. Aakriti Chaudhry, Dr. Payal Jain, and Ms. Nupur Tyagi - worked to enhance the connect between alumnae and their Department and College.
