The real cost of waiting: why starting early beats investing more

The most expensive decision is delay Most people think the key to investing is *how much* you put in. It matters — but far less than *how early* you start. Compounding rewards time exponentially, so every year you wait costs you far more than a year of contributions later can make up.

Two savers, one uncomfortable truth Meet Aisha and Rohan, both aiming to retire at 60, both earning 11% a year.

• Aisha invests ₹5,000 a month from age 25 to 35 — just ten years — then stops and never adds another rupee.
• Rohan starts at 35 and invests ₹5,000 a month all the way to 60 — twenty-five years.

Aisha contributed ₹6 lakh in total. Rohan contributed ₹15 lakh — more than double. Yet at 60, Aisha ends up with a larger corpus. Her ten-year head start, left to compound for 25 more years, beats Rohan's steady quarter-century of saving.

Why this happens Compounding is returns earning returns. The earliest rupees you invest have the longest runway, so they multiply the most. Money invested at 25 has 35 years to double and re-double; money invested at 45 has only 15. The last decade before a goal does most of the heavy lifting — but only if the money is already there to grow.

What to do about it - Start now, even if it's small. A modest amount today outperforms a big amount later. - Automate it so the decision is made once, not every month. - Raise it over time. Step your contribution up with each salary hike; you won't feel it, but the corpus will. - Don't wait to "have enough to invest." Waiting *is* the cost.
