Forex Compound Calculator
Compounding is where trading accounts are made — or quietly destroyed. Project your equity month by month, inject a drawdown at any month, and see the curve before you trade it.
The Math
Equitym = Equitym−1 × (1 + monthly%). A 5% monthly return is +79.6% per year — powerful, but a 10% drawdown at month 6 costs you the growth of several months of that compounding. The curve makes the trade-off visible.
Monthly returns in real trading are never smooth — use a conservative estimate (1–3% for prop-firm traders, 3–5% aggressive).
FAQ
What is a realistic monthly return for a funded trader?
Prop-firm targets of 8–10% are achieved over weeks, not months. Sustainable monthly returns for professionals are 1–5%. Anything above 10% monthly is either exceptional or about to blow up.
How does drawdown affect compounding?
Losses compound too: a 10% drawdown requires +11.1% just to recover. The calculator injects the drawdown at your chosen month so the long-term curve shows its true cost.
Should I withdraw profits or compound them?
Compounding grows fastest, but withdrawing monthly stabilizes income and caps risk. Many prop traders withdraw a fixed % and compound the rest.
