The economy of Erattupetta is robust and multi-faceted, driven primarily by retail trade, agriculture, and substantial remittances from Non-Resident Indians (NRIs) working in the Gulf countries. The influx of foreign currency has given the town a high standard of living, visible in its bustling commercial streets and large residential homes.
As a historic trading center, Erattupetta is a major market for hill produce, especially natural rubber, which is the economic lifeblood of the region. The town serves as a commercial hub for surrounding villages, resulting in a thriving retail and service sector. In recent years, its status as the gateway to the Vagamon hill station has spurred growth in the hospitality and tourism sectors, with increasing numbers of restaurants, taxi syndicates, and transient accommodations.
