Why time beats money (when investing)

Here's a question most people answer wrong:

Who ends up with more money at 60. Someone who invests ₹5,000/month from age 22 to 32 (10 years) and then stops, or someone who invests ₹5,000/month from age 32 to 60 (28 years)?

The person who started earlier. By a lot.

The math

Assume both earn 12% a year, every year, and both leave the money untouched until 60:

• Person A: ₹5,000/month × 10 years = ₹6 lakh invested → worth ~₹3.26 crore at 60
• Person B: ₹5,000/month × 28 years = ₹16.8 lakh invested → worth ~₹1.37 crore at 60

Those crore figures are an illustration of the maths, not a forecast of what you'll get. Real markets don't hand out a flat 12% every year. Some years are +30%, some are −20%, and the order they arrive in changes the ending. Plug in 10% instead and both numbers shrink hard.

The gap between them is the sturdier part, though not unconditional either. It holds anywhere in equity-like territory: assume 10%, or even 8%, and Person A is still ahead having put in a fraction of the money. Push the rate down towards 3% and it flips, because money that barely grows in the first 10 years leaves the extra 28 years with almost nothing to multiply. The crossover sits somewhere around 6%. Above it, starting earlier wins. Below it, the person who simply invested more does.

> This is compounding. Earning returns on your returns. Einstein allegedly called it the eighth wonder of the world. Whether he did or not, the math is real.

How compounding works

Year 1: ₹1,00,000 at 12% → ₹1,12,000

Year 2: ₹1,12,000 at 12% → ₹1,25,440 (interest on interest)

Year 10: ₹3,10,585

Year 20: ₹9,64,629

Year 30: ₹29,95,992

The curve bends dramatically in the later years. The first 10 years feel slow. The last 10 years are explosive.

The takeaway for your 20s

Every year you delay investing is not just one year of missed returns. It's the compound effect of that year multiplied across decades. On the 12% assumption used above, contributing from 22 instead of 32, same ₹5,000 a month, right through to 60, changes the ending by a crore-scale number. Lower the assumed rate and that gap shrinks with it.

Time is the one asset money cannot buy back.

Takeaway. At equity-like returns, starting 10 years earlier beats investing nearly 3× more money. The edge comes from the years rather than the amount, and it fades as the assumed return falls. Time is the one variable you cannot buy back.
