Every other SIP calculator shows you what you'll have. This one also shows what a few extra years could add, not to make you wince at the past, but to show you exactly why starting today is worth it.
That gap was never about how hard you tried. Compounding rewards time, not effort, which is genuinely good news: a ₹10,000 SIP starting at 25 beats a ₹20,000 SIP starting at 35, even though the second person put in more. You don't need to be richer, just earlier.
So here's the only takeaway that matters. The best time to start was years ago. The second best time is today, and today is the one you can actually do something about.
