The later years do most of the work
Look at how the growth is spread out. In the first 10 years, ₹1 lakh earns about ₹2,10,585. Between year 15 and year 20, the value jumps from ₹5,47,357 to ₹9,64,629, a rise of ₹4,17,272 in just five years. That is nearly double what the whole first decade earned.
So the biggest gain from a one-time investment comes from not touching it. Pulling the money out at year 10 gives up the part of the curve where compounding really speeds up.
Frequently asked questions
How much will ₹1 lakh become in 5 years?
At an assumed 12% a year, ₹1 lakh invested once can become about ₹1,76,234 in 5 years, so roughly ₹76,234 of returns. Over a short period like this, actual market returns can be well above or below 12%.
How long does ₹1 lakh take to become ₹5 lakh?
At 12% a year, it gets there within 15 years. The value after 10 years is about ₹3,10,585, and after 15 years it is ₹5,47,357. Real returns will vary, so treat this as a rough guide.
What will ₹1 lakh be after 20 years?
About ₹9,64,629 at an expected 12% a year, which is 9.65 times what you put in. Close to ₹8,64,629 of that is returns. This assumes you stay invested the whole time and the average return really is 12%.
Is putting ₹1 lakh in one go risky?
In the short term, yes. If markets fall soon after you invest, the value may sit below ₹1 lakh for a while. Over 10 years the example shows ₹3,10,585 at 12%, but nothing is guaranteed. Money needed within 3 years is safer elsewhere.
