Compounding keeps working after you stop paying in. So if you can only invest for a few years, the early years count the most.

## Three people, same ₹10,000 a month

We follow three people for the same 20 years:

- **Mr. Early Bird** pays for years 1–10, then lets the money sit. He puts in ₹12 lakh.
- **Master Disciplined** pays for all 20 years. He puts in ₹24 lakh.
- **Ms. Slow Coach** waits 10 years, then pays for years 11–20\. She puts in ₹12 lakh.

## What each one has after 20 years

An illustration at 10% a year:

| Investor           | Money put in | Value after 20 years |
| ------------------ | ------------ | -------------------- |
| Master Disciplined | ₹24 lakh     | ₹72.4 lakh           |
| Mr. Early Bird     | ₹12 lakh     | ₹52.3 lakh           |
| Ms. Slow Coach     | ₹12 lakh     | ₹20.1 lakh           |

Mr. Early Bird and Ms. Slow Coach put in the same money. Mr. Early Bird ends with about 2.6 times more. His money had 10 more years to grow.

## Does it hold on real market data?

Yes. We tested all 88 twenty-year periods of the Nifty 50 (with dividends) from 1999 to 2026.

- Mr. Early Bird ended ahead of Ms. Slow Coach in **all 88** periods.
- Mr. Early Bird ended with **75–82%** of Master Disciplined's money, with half the instalments.
- Ms. Slow Coach ended with **18–25%**.

These are index returns, not fund returns. They leave out costs and tax.

## The honest part

This is not a reason to stop a SIP.

- Master Disciplined ended with the most money, every time. If you can keep going, keep going.
- Real returns jump around. 10% a year is only an illustration.
- If your window to invest is short, use it early: before school fees, a home loan or a career break.

## Questions people ask

#### If I stop my SIP after 10 years, does my money keep growing?

Yes. Units you already hold stay invested and move with the market. In our illustration, ₹12 lakh paid in over 10 years grew to about ₹52.3 lakh by year 20.

#### Is it better to invest early for 10 years or late for 10 years?

Early. On real Nifty 50 data, paying in the first 10 years beat paying in the last 10 years in all 88 twenty-year periods we tested.

#### Should I stop my SIP after 10 years, then?

No. Paying for all 20 years ended with the most money every time. The lesson is for people whose window is short: use the early years.

#### What return does this assume?

The illustration uses 10% a year. That is an assumption, not a promise. The real-data check uses Nifty 50 index returns, before costs and tax.

## Start early. Let time finish the job.

If you can keep a SIP going, keep going. If your window is short, make the early years count.
