A subsequent purchase refers to any additional investment made into a mutual fund scheme after the initial subscription. Once an investor has completed their Know Your Customer (KYC) requirements and made the first investment in a scheme, all future investments into that same folio are treated as subsequent purchases. In India, SEBI and AMFI have set minimum subsequent purchase amounts that are often lower than the minimum initial investment threshold—sometimes as low as ₹500 for lump sum and ₹100 for SIPs. Subsequent purchases can be made online through fund houses, registrar platforms, or investment platforms like Ventura.
