Why compounding cuts both ways
Compound vs withdraw — which is better?
Compounding multiplies your gains exponentially when the trader is performing — but also accelerates losses if they enter a drawdown. Withdrawing locks in profit and resets your exposure. A common middle path: withdraw 50% of monthly profits, let the rest compound. The toggle lets you compare both extremes.
What's a realistic monthly ROI to plan around?
Across thousands of copy traders on Bitunix, BTCC, and MEXC, sustainable monthly ROI for traders who have lasted 6+ months tends to land in the 3–10% range. Anything above 15% monthly is either a short-term streak or comes with high drawdown risk. Plan around 5–8% as your baseline and treat anything above as upside.
How does the realism factor work?
It multiplies the ROI input you provided. So if you enter 12% monthly with a realism factor of 0.7, the calculator projects forward at 8.4% monthly. This is the simplest way to bake in mean-reversion without modeling it explicitly. For aggressive optimism, set 1.0. For "this trader will probably revert to average", set 0.5.
What about the "rule of 72"?
A useful shortcut: divide 72 by your monthly net ROI to get the number of months for your account to double. At 6% net monthly, account doubles in ~12 months. At 10%, ~7 months. At 3%, ~24 months. The calculator does the actual math, but this is a sanity check.
