How does compounding work in forex trading?

Compounding means reinvesting your profits so that future returns are earned on a larger base. Each period, the balance is multiplied by (1 + rate) and any periodic contribution is added. A consistent 5% monthly return on $10,000 grows to ~$17,959 after 12 months — not $16,000 as simple interest would give — because each month's profit earns a return in subsequent months.

What is a realistic monthly return for forex trading?

Professional retail traders typically target 2–5% per month as a sustainable long-term target. Returns above 10% per month are possible but typically come with proportionally higher risk and drawdown. The calculator warns when the rate per period exceeds 50%, as such returns are very high risk and difficult to sustain. Use conservative estimates to avoid planning on unrealistic outcomes.

Can I model weekly or daily compounding?

Yes. Simply enter the return per week in the rate field and set periods to 52 for a yearly projection. For daily compounding, use the daily return rate (e.g. 0.2%) and set periods to 252 (trading days in a year). The periodic contribution field works on the same cadence — weekly contributions use the weekly period.

What does the Contribution Per Period field do?

It adds a fixed amount to your balance at the end of each period, after the return is applied. This models regular deposits into your trading account. A negative value models regular withdrawals — useful for planning living expenses drawn from a trading account. Set it to 0 for pure compounding with no additional capital.

Why is Total Return always higher than the per-period rate × periods?

Because compounding generates returns on returns. At 5%/month × 12 months, simple interest would give 60% total return. Compounding gives (1.05^12 − 1) × 100 ≈ 79.6% — about 33% more than simple interest. The difference grows dramatically with higher rates and more periods, which is why consistent profitability over time compounds powerfully.

Formula

Compound growth formula

Per Period


Balance(n) = Balance(n−1) × (1 + Rate) + Contribution

No Contribution


Final Balance = Initial × (1 + Rate)^Periods

Total Return %


Total Return % = (Final − Initial) ÷ Initial × 100

Rate = ratePerPeriod ÷ 100 · Contribution added at end of each period after applying the rate.

Worked Example

Given

$1,000 starting balance · 10% return per period · 3 periods · no contribution

Period 1: $1,000 × 1.10 = $1,100.00
Period 2: $1,100 × 1.10 = $1,210.00
Period 3: $1,210 × 1.10 = $1,331.00
Total Profit: $1,331 − $1,000 = $331.00
Total Return: $331 ÷ $1,000 × 100 = 33.1%
