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 after each period's gain. The withdrawal is capped at the available post-gain balance, so the account cannot fall below zero.

What currency does the calculator use?

Outputs are formatted with a dollar symbol ($) representing your account base currency. The compounding math and return percentages apply identically to any currency (such as EUR, GBP, or USD).

How many periods can I project?

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

Summary

The Forex Compounding Calculator projects how a trading account grows when profits are reinvested each period. Enter your starting balance, the consistent return percentage per period (daily, weekly, or monthly), and the number of periods to see the final balance, total profit, and a full period-by-period table. An optional withdrawal amount lets you model taking profits out each period instead of fully compounding.
