An ideal method for implementing step-up SIPs involves initiating new, separate SIPs each year with the increased amount, rather than relying on platform features.
"the ideal way according to me is the following, suppose you have done a SIP of Rs. 000, next year you have to step up from Rs. 10, so increase it by Rs. 00 and start a new SIP of Rs. 00, then next year you have to do it at Rs. 5500, now at Rs. 10, that means Rs. 50, so now you will start another SIP of Rs. 50 and so on and so forth"
