What if it grows every day
The famous "1% a day" idea. Pick a small start, a gain per period and see where it lands, and how long it would really take to reach a billion.
About this calculator
The maths behind the claim
Earning 1% a day means each day's gain is calculated on the new total: ₹100 becomes ₹101, then ₹102.01, then ₹103.03. Compounded over 100 days, ₹100 becomes about ₹270, not the millions the viral version of the story promises. Reaching ₹100 crore at that rate would take roughly 1,620 days, or about four and a half years.
To turn ₹100 into ₹100 crore in 100 days you would need about 17.5% a day, every single day, without one losing session. The stories that circulate usually assume doubling every day, which is an entirely different claim.
Why nobody actually does it
One percent a day compounds to roughly 3,678% a year. No fund, trader or business in history has sustained anything close to that, and the arithmetic shows why: within a few years the position would be larger than the market it trades in.
Real returns also do not arrive in a smooth line. A single bad stretch undoes a great deal of compounding, because losses and gains are asymmetric. For scale, a respectable 12% a year works out at about 0.03% a calendar day.
Common questions
How much is 1% a day over a year?
Compounded, about 3,678% a year, which is roughly 37 times your money. That is why the claim should be treated as arithmetic rather than a plan.
Can anyone really make 1% a day trading?
Not sustainably. The rate compounds to a figure no investor or fund has ever maintained, and SEBI's own studies show the large majority of individual traders in equity derivatives lose money.
What does ₹100 become at 1% a day for 100 days?
About ₹270. Compounding starts slowly, which is why the early days feel so unremarkable and the headline figures only appear over years.
