Trading Compounding Calculator
Compounding is the quiet force that turns modest consistency into serious money, given enough time. This calculator projects an account month by month, with optional deposits, so you can see what patience actually pays.
Use it honestly: enter the monthly return you can defend with a track record, not the one you saw in an advertisement.

What realistic numbers look like
Sustained 3-5% monthly returns place a trader among the best in the world. Most hedge funds would celebrate 20-40% in a year. At 4% monthly, $1,000 becomes roughly $2,563 in 24 months without deposits; add $100 a month and the figure roughly doubles again. No step in that journey requires heroics, only repetition.
Claims of 20-50% per month are either luck operating briefly, or risk levels that eventually return the account to zero. The same compounding math that grows accounts also destroys them: three -20% months erase half an account.
Why drawdowns dominate the math
A -50% month needs a +100% recovery. Losses compound against you asymmetrically. This is why the professionals you want to imitate risk 1% per trade and accept smaller monthly figures: they protect the base that compounding needs to work on. Growth is the reward for surviving.
Pair this tool with the position size calculator: compounding sets the destination, sizing protects the journey.
Frequently asked questions
What is a realistic monthly return for a trader?
Consistent professional traders typically target 2-6% per month, and even that is uneven: losing months are normal. Anything advertised above 10-15% monthly, sustained, should be treated with extreme skepticism.
How long does it take to double a trading account?
At 4% monthly compounding, an account doubles in about 18 months; at 6%, about 12 months. The rule of 72 gives a quick estimate: divide 72 by the monthly percentage to get months to double.
Should I withdraw profits or compound them?
Many traders use a hybrid: compound fully until the account reaches a meaningful size, then withdraw a fixed percentage of profitable months. Withdrawals make progress tangible and reduce the temptation to over-risk a large balance.
Does this calculator account for losing months?
It applies one average rate every month, which smooths reality. Real equity curves are jagged. The projection is a direction, not a promise. Enter a conservative average to keep it honest.
Compounding needs one input: a real edge.
The Trading Mentorship Program exists to build exactly that: a framework you can repeat for years, not a hot streak.
