Trading Compounding Calculator — Forex & Binary
Compounding applies each period’s return to the balance remaining from the previous period. A calculator can explore assumptions, but it cannot establish a realistic income target or predict a trading record. Variable returns require multiplying the actual period factors. A +10% month followed by −10% leaves $990 from $1,000: the arithmetic average is zero but the compounded result is −1%. Use a geometric growth rate for a constant-rate equivalent. Fees, taxes, losses and withdrawal timing can materially change the path; no monthly return range is guaranteed.

Why Use the Compounding Calculator?
Compounding applies each period’s return to the balance remaining from the previous period. A calculator can explore assumptions, but it cannot establish a realistic income target or predict a trading record. Compare the displayed result with the worked example and confirm the assumptions before using it.
Formula Used
Period balance = prior balance × (1 + monthly return) − actual withdrawal; total gain = final balance + withdrawals − startWorked Example
Starting with $1,000 at a hypothetical 1% monthly return gives $1,126.83 after 12 months without withdrawals. With $10 withdrawn at the end of each month, the balance stays $1,000 and total withdrawals are $120. These are arithmetic scenarios, not expected performance.

Interpret the result
Variable returns require multiplying the actual period factors. A +10% month followed by −10% leaves $990 from $1,000: the arithmetic average is zero but the compounded result is −1%. Use a geometric growth rate for a constant-rate equivalent. Fees, taxes, losses and withdrawal timing can materially change the path; no monthly return range is guaranteed.
