Question 1

How is time to goal calculated?

Accepted Answer

It solves the compounding formula for the number of periods: periods = ln(target ÷ start) ÷ ln(1 + rate). Each period multiplies your balance by (1 + rate), so reaching a target is a matter of how many multiplications you need — which grows slowly as the target rises because of compounding.

Question 2

Is a steady per-period return realistic?

Accepted Answer

Rarely. This calculator assumes the same return every single period with no losing streaks, which almost never happens in live trading. Use it to understand the power and limits of compounding, not as a plan — real equity curves are lumpy, and a few bad periods reset the clock badly.
