Trade Growth Calculator: Project Your Account Growth With Real Trading Stats
Enter your win rate, average gain, and average loss to project trade-by-trade account growth. Run 1,000 Monte Carlo simulations to see the full range of outcomes — from worst case to best case — based on the same stats.
Expectancy = (WinRate × AvgGain) − (LossRate × AvgLoss)
Each trade: Balance × (1 + Expectancy) − Fee
Simulation (Monte Carlo):
Each trade: Random(0–1) < WinRate → gain, else → loss
Repeated 1,000× to show the full range of outcomes
Expected Growth shows a single deterministic path. Simulation shows what could actually happen — including lucky and unlucky streaks.Next Step: Start by calculating the right position size for your next trade with our Position Size Calculator.
How to Use This Calculator
Choose Your Mode
- Expected Growth: Deterministic projection — each trade gains or loses the expected value based on your stats. Best for understanding your theoretical trajectory.
- Simulation (1,000 Paths): Randomized Monte Carlo — each trade is individually randomized across 1,000 full simulations. Best for understanding the range of possible outcomes and the role of luck.
Enter Your Starting Capital
Your current account balance. This is the starting point for the projection.
Enter Your Trading Stats
- Number of Trades: How many trades to project (e.g., 100 trades = roughly 1 month at 5/day).
- Trade Frequency: How often you trade — Daily, Weekly, or Monthly. Used to calculate time-based metrics like annualized return and monthly contribution timing.
- Win Rate (%): The percentage of your trades that are profitable. Be honest — use your actual journal stats, not what you hope to achieve.
- Average Gain (%): Your average percentage gain on winning trades.
- Average Loss (%): Your average percentage loss on losing trades.
Add Contributions and Fees (Optional)
Monthly Contribution adds a deposit to your account once per month (timed correctly based on trade frequency — not added to every trade). Fee Per Trade deducts a flat commission from each trade.
Toggle Compounding
With compounding ON (default), each trade's P&L is calculated on your current balance — meaning winners get larger as your account grows, but losers hurt more too. With compounding OFF, each trade uses your initial capital for the P&L calculation — a fixed-dollar-risk model.
Click Calculate (or Run Simulations)
Expected Growth mode produces results instantly. Simulation mode takes 1–2 seconds to run 1,000 paths. Results show the projected balance, total profit, profit per trade, annualized return, max drawdown, total fees, and your expectancy per trade. In simulation mode, you also see the median, worst case, best case, and 25th/75th percentile outcomes.
Example Scenarios
Example 1: Profitable Day Trader — Expected Growth
The callout confirms: "Positive expectancy of 0.43% per trade. These projections assume your stats remain consistent — the hardest part."
Capital: $25,000 | 100 trades | Daily | Win Rate: 55% | Avg Gain: 2% | Avg Loss: 1.5%
Example 2: Negative Expectancy — The Reality Check
The calculator warns: "Negative expectancy. These stats lose money over time regardless of luck. Improve your win rate, increase avg gain, or decrease avg loss before risking real money."
Capital: $10,000 | 50 trades | Win Rate: 40% | Avg Gain: 1.5% | Avg Loss: 2%
Example 3: Monte Carlo — Same Stats, Different Luck
The range from $18K to $68K — all with the exact same win rate and R:R — shows why position sizing and consistency matter more than any single trade. The simulation makes this viscerally clear.
Capital: $25,000 | 100 trades | Win Rate: 55% | Avg Gain: 2% | Avg Loss: 1.5%
Running 1,000 simulations with these same stats produces:
❓ Frequently Asked Questions (FAQ)
What is a trade growth or compounding calculator?
A trade growth or compounding calculator shows how your trading account could grow over time when profits are reinvested. It factors in your initial capital, trade frequency, win rate, average gains/losses, and compounding to give a clear growth projection.
Why is a compounding calculator important in trading?
It helps traders visualize long-term growth and the power of reinvesting profits. By planning trades with compounding in mind, you can make informed decisions on position sizing, trade frequency, and realistic account growth expectations.
How do you calculate account growth with compounding?
The basic formula is:
Account Value Next Trade = Current Account Value × (1 + Trade Return %)
Example: Start with $10,000, gain 2% per trade → after 5 trades:
$10,000 × 1.02⁵ ≈ $11,041
Can this calculator include recurring contributions?
Yes. You can add deposits or withdrawals to see how regular contributions affect overall growth. This makes it useful for planning both short-term and long-term trading strategies.
How does trade frequency affect compounding?
More trades per week or month can accelerate growth if the strategy is profitable. However, higher frequency can increase risk and trading costs, so the calculator lets you test different frequencies and outcomes.
How do win rate and average gain/loss impact account growth?
Higher win rates and larger average gains accelerate growth, while larger losses slow it down. The calculator factors these variables to show realistic account projections over time.
Can the calculator account for trading fees?
Yes. You can input flat fees or percentage-based commissions. The calculator subtracts these from each trade to show your net account growth, giving a more accurate projection.
Is the compounding calculator accurate?
Yes, mathematically it’s precise based on the inputs. Real-world results may vary due to slippage, market volatility, or changes in trading performance. It’s a planning tool to visualize potential outcomes, not a guarantee.
How does a compounding calculator help traders?
It helps traders set realistic goals, plan risk management, and understand the long-term effect of reinvesting profits. By showing projected growth, it encourages disciplined trading and prevents over-risking.
Can this calculator simulate different trading strategies?
Yes. You can adjust win rate, trade size, average gain/loss, and trade frequency to simulate multiple strategies. This helps compare outcomes and select the most efficient approach for consistent account growth.
