How to use this compounding calculator
- Enter your starting capital.
- Pick the compounding period — monthly is the most realistic for most traders; daily is useful mainly as a reality check.
- Enter the return per period you expect, based on what you have actually achieved rather than what you hope for.
- Set the number of periods to project.
- Optionally add a contribution per period, or a negative number to model regular withdrawals.
What a realistic return looks like
The table below compounds ₹1,00,000 for twelve months at several monthly rates. Use it to calibrate what you are aiming for before you commit capital to a strategy that requires the bottom row.
| Monthly return | After 1 year | Annualised |
|---|---|---|
| 1% | ₹1,12,683 | 12.7% |
| 2% | ₹1,26,824 | 26.8% |
| 4% | ₹1,60,103 | 60.1% |
| 8% | ₹2,51,817 | 151.8% |
| 15% | ₹5,35,025 | 435.0% |
For context, top-performing mutual funds and professional traders sustain roughly 15% to 30% a year over long periods. Anything in the lower rows of this table is already excellent; the bottom row is not a plan.
How compounding works in trading
Final capital = Starting capital × (1 + Return rate) ^ Number of periodsEach period's return is earned on everything you ended the last period with, profits included. The curve is almost flat early and then steepens sharply, which is why consistency matters more than intensity — and why most people underestimate what a modest, repeatable return is worth.
₹1,00,000 growing at 4% a month reaches about ₹1,60,000 in a year and roughly ₹2,56,000 in two. The second year adds far more than the first, despite the identical rate.
The reality check
Run 1% a day over 250 trading days and ₹1,00,000 becomes over ₹12,00,000 — a 1,100% annual return. It sounds modest daily and is absurd annually. That gap is precisely what "just 1% a day" marketing relies on, and this calculator is the fastest way to see through it.
Compounding cuts both ways
The same mechanism that grows a good run accelerates a bad one, because losses also compound on a shrinking base. Many traders withdraw profits periodically instead of compounding everything, so one bad stretch cannot take back several good months. Before deciding, run the same numbers through the drawdown recovery calculator.
What this model leaves out
Real returns are not a smooth rate — they are a sequence of wins and losses with gaps and drawdowns, and the order matters. Taxes and charges are excluded too. Treat the output as the arithmetic ceiling of a return assumption, not a forecast.
Frequently asked questions
Each period's return is earned on the capital you ended the previous period with, profits included. Final capital = starting capital × (1 + return rate) raised to the number of periods. The effect is slow at first and then disproportionate, which is why consistency beats intensity.
