To become a crorepati, a person would have to invest ₹450 daily in a SIP (₹13,500 monthly) for 18 years at a 12% expected rate of return. The resulting corpus would be ₹1,03,33,429, with a total investment value of ₹29,16,000. With a step-up SIP of 10%, the duration would be cut to 15 years and the corpus would be ₹1,17,23,196.
