A curve this steady needs reads that hold up.

The maths
Ending balance = start x (1 + gain %) ^ periods Total profit = ending balance - start
Compounding assumes every gain stays in and every period repeats. Real returns do neither, and one losing period resets the curve, so read this as arithmetic rather than a plan.
Worked example
10,000 USD growing 5% a month for twelve months ends at 17,959 USD. That is 79.6%, not the 60% that twelve times five would suggest.
Why is the total more than the periods times the gain?
Each period grows the base the next one works on. The gap widens the longer it runs, which is the entire point of compounding.
Is 5% a month realistic?
As a sustained average, no. It is useful for seeing the shape of the curve rather than as a target. Large funds are measured in single digits per year.
What about losing periods?
This calculator does not model them. A 10% loss needs an 11.1% gain to undo, and that asymmetry is what the drawdown recovery calculator is for.
