What does "per-period return" mean?

It is the percentage gain applied to the account balance at the start of each period. For example, a 3 % monthly return on a $1,000 account earns $30 in month 1, then 3 % is applied to $1,030 in month 2, and so on.

Does this account for losing streaks?

No — the calculator assumes a constant return every period, which is a best-case projection. Real trading involves drawdowns and variance. Use it to understand the mathematical ceiling of compounding, not as a guaranteed forecast.

How does the withdrawal option work?

If you enter a withdrawal amount, that fixed sum is subtracted from the balance after each period's gain is added. If the balance after gain minus withdrawal would go below the starting balance, the withdrawal is capped at zero for that period.

What currency does the calculator use?

The calculator is currency-agnostic. Whatever unit you enter as the starting balance (USD, EUR, pips, etc.) is the unit shown throughout the results.

How many periods can I project?

Up to 1,000 periods. Beyond that the table becomes impractical, but the summary figures are still accurate.
