Calculating Net Trading P&L
Net Trading P&L is the true measure of your trading performance. It shows how much money your trading actually made or lost, separate from deposits and withdrawals.
The Formula
Net Trading P&L = (Ending Balance − Starting Balance) − Deposits + Withdrawals
This formula isolates trading performance by:
Starting with the raw balance change
Subtracting deposits (not trading gains)
Adding back withdrawals (were in the account before removal)
Step-by-Step Example
Let's walk through a complete example:
Starting point:
Starting balance: $10,000
Activity during the month:
Deposited: $2,000
Withdrew: $1,000
Ending balance: $12,500
Calculation: P&L = ($12,500 − $10,000) − $2,000 + $1,000 P&L = $2,500 − $2,000 + $1,000 P&L = $1,500
Interpretation: Your trading made $1,500. The balance increased by $2,500, but $2,000 of that came from your deposit. After accounting for the $1,000 withdrawal, the trading contribution was $1,500.
Different Time Periods
Month-to-Date (MTD)
Uses:
Starting balance = Balance on first day of month (or account creation if later)
Ending balance = Current balance
Deposits/Withdrawals = This month's transactions
All-Time
Uses:
Starting balance = Original starting balance when account was created
Ending balance = Current balance
Deposits/Withdrawals = All transactions ever
Custom Period
For any custom date range:
Starting balance = Balance at period start
Ending balance = Balance at period end
Deposits/Withdrawals = Transactions within that period
Percentage Return
The platform also calculates percentage return:
Return % = (Net Trading P&L ÷ Starting Balance) × 100
Using our example: Return = ($1,500 ÷ $10,000) × 100 = 15%
This shows your percentage gain relative to where you started.
Where to See Your P&L
In the Account Drawer
The Overview tab shows:
Net Trading P&L (MTD)

In the Private Accounts Table
The table may show a P&L column for quick comparison across accounts.
On the Dashboard
The Private Accounts summary card shows:
Total Net Trading P&L across all private accounts
Combined performance metrics
What P&L Tells You
Positive P&L
Your trading made money. This is the goal.
Negative P&L
Your trading lost money. Important to acknowledge and analyze.
Zero P&L
Your trading broke even. Neither made nor lost money.
P&L Accuracy Depends On
Your P&L is only as accurate as your data:
Balance Updates
Frequent updates = accurate P&L tracking
Infrequent updates = gaps in the picture
Deposit/Withdrawal Recording
Complete records = accurate P&L
Missing transactions = skewed P&L (usually in wrong direction)
Starting Balance
Correct starting point = accurate baseline
Wrong starting balance = all calculations are off
Common P&L Questions
"My P&L seems wrong"
Check:
Are all deposits recorded?
Are all withdrawals recorded?
Is the starting balance correct?
Is the current balance up to date?
"P&L changed after I added a deposit"
Correct! Recording a deposit adjusts the P&L calculation. If your balance increased but you deposited money, the increase wasn't all from trading.
"Can P&L be positive if balance went down?"
Yes! If you withdrew more than your trading loss, the balance goes down but P&L can still be positive.
Example:
Start: $10,000
Withdraw: $3,000
End: $8,000
P&L: $8,000 − $10,000 + $3,000 = $1,000 profit
Comparing Across Accounts
If you have multiple private accounts:
Each has its own P&L
The platform may show a combined total
Compare percentage returns to see which accounts perform best
P&L vs. Dashboard Metrics
Dashboard shows: Money flowing in and out of your entire business (payouts, expenses, etc.)
Private Account P&L shows: Trading performance within your personal accounts
These are different metrics:
Dashboard focuses on cash flow
P&L focuses on trading skill
Private account P&L doesn't directly appear in Dashboard "Money In/Out" because you're not extracting it as business income. If you withdraw from a private account, that withdrawal isn't business revenue—it's your own capital.
Using P&L for Decisions
Evaluate Your Strategy
If P&L is consistently positive, your strategy works. If consistently negative, something needs to change.
Set Realistic Goals
If you made 5% monthly, that's your baseline. Aiming for 100% might be unrealistic.
Know When to Add/Remove Capital
Strong positive P&L → Consider adding more capital
Negative P&L → Maybe reduce exposure, improve skills first
Compare to Prop Trading
How does your private account P&L compare to your prop firm payouts? This shows where your edge might be stronger.
Summary
Net Trading P&L is your truth meter for trading performance:
It removes the noise of deposits and withdrawals
It shows what your trading actually produced
It's the only reliable measure of trading skill in private accounts
Trust this number. It doesn't lie.
