With a target corpus of ₹1 crore and a 10-year tenure, investing ₹43,500/month with estimated 12% returns can help a person become crorepati. This will help get nearly ₹49-lakh returns on investment of ₹52.2 lakh, giving a total corpus of over ₹1.01 crore. In case ₹43,500 is unaffordable, investors can choose 'step-up SIP', bringing payments down to ₹30,000/month.
