You see a positive profit figure for your Binance copy trading, but your total account net return ends up negative. This can be very confusing, and you may even suspect the platform made a calculation error.

The answer is almost never a system error: your profit is eaten up by three "hidden costs": trading fees, funding rates and slippage. The profit figure shown for the lead trader only counts the price difference between their entry and exit, and does not deduct these actual costs generated on your account.
Step 1: Check the definition of gross profit and net profit
First confirm what the two figures on your copy trading dashboard actually mean.
Gross Profit (or Total Return): Usually only calculates the price gap between the opening position price and closing position price, that is, how many pips the trade earned.
Net Profit (Net Return): Deducts all actual fees you paid from that price difference.
If your gross profit is positive but net profit is negative, that means costs have completely eroded your profit margin.
Step 2: Verify the 3 core "cost deduction" items
1. Trading Fees
The platform charges fees every time you open and close a position. The copy trading system uses your own account's fee tier, not the lead trader's fee tier, to deduct fees. If you don't use BNB to pay fees or have a low fee tier, two-way trading fees can directly eat several percentage points of your profit.
2. Funding Rates
If you hold a position for more than 8 hours, funding rate settlement will apply. If you have multiple funding rate payouts during the copy trading period, this cost will keep reducing your account balance. The yield displayed on the lead trader's profile almost never includes this cost.
3. Slippage and Entry Delay
Your copy trade execution price will never be exactly the same as the lead trader's price. When the market is highly volatile, your order may be executed several pips away from the lead trader's entry price. If the lead trader enters a good position but your copy order fills at a worse, higher price, this will create a gap between your actual return and the expected return.

Step 3: Confirm you are using the same profit calculation standard
The "profit" number you see and the data the lead trader displays may not be calculated using the same rules.
Lead Trader Displayed Yield: Usually calculated based on a fixed ratio, and often does not fully deduct variable costs including funding rates and slippage.
Your Actual Yield: Calculated based on your real executed entry price and all fees deducted from your account, so there is normally a difference between the two figures.
Verification method after operation: Go to the [History] section of your copy trading account, check the "Closed PnL" and "Fees / Funding Fees" columns for every single trade. Recalculate manually using the formula: "Closed PnL - Trading Fees - Funding Fees". If the result matches the "Net Return" number shown on the page, it confirms that fees and slippage consumed all your profit.
Next steps: After confirming high fees caused your negative net return, check if you have enabled the "Use BNB to deduct trading fees" option to cut costs. If slippage is the main issue, next time you select a lead trader, prioritize those with a relatively stable trading style and lower operation frequency.
