This calculator is for informational and educational purposes only. It does not represent financial advice. Projected growth is hypothetical and based on a fixed rate, which real trading cannot guarantee. You are fully responsible for your own risk management and trading decisions. Past performance does not guarantee future outcomes. Trading forex carries a high level of risk and may not be suitable for everyone. Never trade with money you cannot afford to lose.
What is the Forex Growth Calculator?
The Forex Growth Calculator projects how an account balance can grow over time when profits are compounded and position sizes scale with equity. It is a planning tool, not a guarantee: real returns come with drawdowns and variance, and the curve shown is what would happen if every period exactly hit the stated return. Use it to set realistic targets and to see how powerful consistent compounding becomes when given enough time.
How to use it
- Enter the starting balance of the account.
- Enter the expected return per period (per week, per month, depending on your timeframe).
- Enter the number of periods to project.
- Confirm compounding is enabled if you want each gain reinvested into the next period.
- Read the projected final balance and the period-by-period schedule.
Worked example
$5,000 starting balance compounded at 2% per week for 50 weeks.
- Final balance: $5,000 × (1.02)50 ≈ $13,461
- Total return: 169% over the year (assuming every week hits target)
The same projection at 1% per week ends at $8,222. Small changes in the periodic return compound into very different end states.
Frequently asked questions
Is 2% per week realistic?
Sustainably, no. Consistent 2% per week compounded equals roughly 180% per year, well above what any institutional trader produces. Treat the projection as a stress test of how a target translates to wealth, not a forecast.
How do drawdowns affect the curve?
The calculator assumes flat per-period returns. In reality, losses force you to size down (smaller lot, lower cash gain on the next win), which lengthens the time to a given balance. Use a conservative target and add buffer.
Should I scale lot sizes as the account grows?
Yes, that is the whole point of compounding in forex. If you keep risking the same fixed percent per trade, your dollar risk and reward both scale with balance, which is how a small starting account can grow meaningfully over years.
What is a sensible time horizon for projections?
Six to twelve months is enough to see the compounding effect without pretending you can predict returns out to a decade. Anything beyond two years is mostly a mathematical exercise rather than a useful plan.
