The hardest rupee to invest is the one you put in earliest — because it has the longest time to compound. This tool shows what waiting actually costs: not the few months of contributions you skip, but the years of growth those contributions never get. Move the "delay" slider and watch the gap.
Your plan
If you started today vs. if you wait
Your investing horizon — e.g. years until you retire or reach the goal.
The goal date stays fixed — delaying just shortens how long your money compounds.
Long-run equity SIPs have historically returned ~11–12%. Not guaranteed.

Why a short delay costs so much
It isn't the contributions you skip — it's the growth they would have had
When you delay, you skip a handful of instalments. That feels small. But every rupee you invest keeps compounding right up to your goal date, and the earliest rupees compound the longest. Skipping the first few years removes your money's most powerful growth period — the tail end, where compounding does its heaviest lifting. That's why a delay measured in months or a few years can cost a sum many times larger than the contributions you avoided.
The catch-up trap
To hit the same final number after starting late, you don't just need a slightly bigger SIP — you often need a dramatically bigger one, because your money now has far less time to grow. Waiting rarely makes the goal cheaper; it makes it harder.
How this is calculated
Both scenarios use the same monthly SIP and the same goal date. The "start today" figure compounds for your full horizon; the "delayed" figure compounds only for the years remaining after the delay. The catch-up SIP is the monthly amount the late starter would need to reach the on-time corpus in the shorter time left. All figures assume a steady return for illustration — real returns vary year to year.
