The first crore is the slowest

A friend showed me his SIP statement last week. Eight years of steady investing, and he was deflated. "It barely feels like it moved. Maybe I picked the wrong thing."

He picked fine. He was just standing in the flat part of the curve, and nobody had told him the curve is a hockey stick, not a ramp.

So I pulled the numbers on a plain Rs 10,000 monthly SIP. Never increased. Assume 12 pct a year. The first crore takes about 20 years. Feels glacial. But the second crore arrives in roughly 5 more years, and the third in about 3 after that. Same deposit every month. Each milestone lands faster than the one before, because by then the growth is doing more lifting than your contribution ever could.

Here is the line that lands for most people. Run that SIP for the full 30 years and it grows to around 3.49 cr. You only ever deposited 36 lakh of your own money. The other 3.13 cr is compounding. And roughly 72 pct of that final pot shows up in the last decade alone.

That is why the early years feel like nothing. The reward is back-loaded by design. The boring stretch is not the engine failing, it is the engine warming up.

Which makes the most common mistake also the most expensive one. People quit around year seven because the screen looks flat. They put in the hard, unglamorous decade and then walk away right before the part they were waiting for. The steep bit goes to whoever stays in the chair.

You can raise your SIP. You can pick a cleaner process. The one thing you cannot do is un-skip a decade. Start early, then get out of the way.

The first crore is the slowest one you will ever earn. Sit through it:

The hockey stick, five years at a time

I checked the opening's figures with 1 percent a month and each Rs 10,000 paid at the end of the month. They hold: Rs 98.9 lakh at 20 years, the first crore a month later, the second crore at about 25.5 years, the third at about 28.8, and Rs 3.49 crore at 30. Here is the pot every five years, next to the money actually put in.

At year 7, the stage where the opening says people quit, the pot is about Rs 13.1 lakh on Rs 8.4 lakh put in. Real money, but it looks small next to a monthly salary. The same SIP adds more than that every five months in its last few years.

Why each milestone comes faster

Compounding is growth on growth. The yearly gain is roughly the pot times the return. Early on the pot is small, so the contribution is most of each year's increase. Later the pot is large, and the return on it dwarfs the contribution. The doubling time at a fixed return stays the same, and the rule of 72 gives it: at 12 percent, money doubles in about six years.

A Rs 1 crore pot at 12 percent adds about a crore in the next six years without a single new rupee. A Rs 10 lakh pot adds Rs 10 lakh in the same six years. Same return, same time, a tenfold difference in rupees. That is the hockey stick.

The flat part can be truly flat

The friend's statement felt flat because of compounding's shape. Sometimes it is flat for a simpler reason: the market itself went nowhere. I ran a Rs 10,000 monthly SIP on the Nifty 50 using NSE's month end closes from Oct 2024 to Sep 2026, 24 instalments. Rs 2,40,000 went in. On 30 Sep 2026 the units were worth about Rs 2,23,900, price only, before dividends and costs. Two years of discipline, and the statement showed a loss.

That is normal for a two year window. The 12 percent in the worked example is an average over decades, and averages are made of stretches like this one. The units bought in a falling market are the ones that do the most work if the long run resembles the past. Quitting at a moment like this is quitting exactly where the opening says the expensive mistake happens.

The free Learn module on loss aversion and prospect theory explains why a flat or red statement pulls so hard on the decision to stop. The rule of 72 tool shows doubling times at any return. Related: the cost of waiting and the step up SIP.
