The cost of waiting: start small, start now

A friend turned 35 last week and asked, a little embarrassed, whether it was too late to start a SIP.

Not too late. But I pulled up a number that made him go quiet for a second.

Picture two people, both putting away the same Rs 10,000 a month. The first one starts at 25 and pays in for exactly ten years. At 35 she stops cold and never invests another rupee. The second one starts at 35 and keeps going for twenty five years straight, all the way to 60.

The one who quit at 35 ends up with more. A lot more.

At a 12 pct illustrative return, the early saver's Rs 12 lakh grows to roughly Rs 4.6 crore by the time she is 60. The late saver puts in Rs 30 lakh over those twenty five years and lands at about Rs 1.9 crore. So the early saver invested Rs 18 lakh less, and finished Rs 2.7 crore ahead.

Here is the part that actually matters. By 35, the early saver had already paid in her last rupee. Her Rs 12 lakh had quietly become about Rs 23 lakh. Everything after that, the entire rest of the Rs 4.6 crore, was time doing the work. She was not saving anymore. She was just letting it sit.

That is the whole lesson. The value of a rupee you invest is mostly the time it gets to compound, not the size of the cheque. A rupee invested at 25 gets thirty five years to work. The same rupee at 50 gets ten. Same note, completely different job.

And you cannot backfill the years. The late saver did everything right except the timing, doubled the money, and still came up short. More rupees later do not buy back time already gone.

So if you have been waiting to "start once I earn a bit more", remember: the amount is the part you can fix later. The start date is the part you cannot.

Start small. Start now.

Every five years of waiting halves the pot

I checked the opening's numbers with monthly compounding at 1 percent a month and each instalment paid at the start of the month. They hold: the early saver has about Rs 23.2 lakh at 35 and about Rs 4.60 crore at 60; the late saver about Rs 1.90 crore. Then I asked the friend's real question a different way. Same Rs 10,000 a month, kept going until 60. What does each five years of delay cost?

Starting at 30 instead of 25 means paying Rs 6 lakh less and ending with Rs 2.97 crore less. That is the price of five years, and it is paid in the last decade, long after the decision to wait was made.

Try your own start date

Slide the years from 25 to 35 and watch the gap between the two lines. The money put in grows in a straight line. The value curves away from it, and most of that curve comes after year 20.

The same crore in today's rupees

There is an honest correction that belongs next to the big number. Rs 4.6 crore in 35 years will not buy what Rs 4.6 crore buys today. All India CPI inflation was 4.82 percent in Aug 2026, on MOSPI's figures. If prices rose at that rate for 35 years, they would be about 5.2 times today's level, so Rs 4.6 crore then is worth about Rs 89 lakh now.

This does not change the lesson. The late saver's Rs 1.9 crore shrinks by the same kind of factor. The early start still wins by about the same multiple. What it changes is the goal: a retirement number has to be set in future rupees, and the inflation figure decides how large that is. The free Learn module on inflation and its investment impact shows how to convert any goal into the rupees you will need.

What the early saver's ten years look like

1. Age 25First Rs 10,000

   Thirty five years of compounding ahead of this rupee.

2. Age 35Last instalment

   Rs 12 lakh in, about Rs 23.2 lakh in the account.

3. Age 45No new money

   About Rs 77 lakh, from compounding alone.

4. Age 55Still none

   About Rs 2.5 crore.

5. Age 60The end of the example

   About Rs 4.6 crore. About 97 percent of it is growth.
