Since it was first held, the Lake Toba Festival has brought many benefits to the local community. The increase in tourist numbers has helped improve the regional economy significantly. Local craftsmen, food sellers and tourism service providers gain additional income from increased tourist visits. Additionally, the festival encourages infrastructure development, such as improving roads and public facilities, which not only benefits the festival but also improves the overall quality of life of local residents. Lodgings, restaurants and shops around Lake Toba also experience a surge in income during the festival, creating new jobs and increasing people's income. Apart from the economic impact, the Lake Toba Festival also plays an important role in preserving Batak culture. Through various arts and cultural activities, this festival promotes and maintains local traditions and customs that may be starting to be forgotten in this modern era. The younger generation is introduced to their cultural heritage through dance, music and handicraft performances, enhancing their sense of pride and cultural identity. This festival also becomes a platform for local artists to showcase their work to a wider audience, including international tourists, which in turn strengthens the value of Batak culture on the global stage. Thus, the Lake Toba Festival is not only an entertainment and recreation event, but also an important means for preserving and developing culture as well as economic empowerment for local communities.

The Lake Toba Festival has become a symbol of pride and identity for the Batak people, as well as a major tourist attraction in North Sumatra. With the support of the government and community, it is hoped that this festival can continue to grow and provide greater benefits in the future.
