How to Use Binance Futures Calculator: PnL, Margin, and Liquidation

Why You Must Calculate Before You Trade

The number one reason traders get liquidated isn’t bad market analysis — it’s entering trades without understanding the numbers. They don’t know their liquidation price, don’t account for fees, and get surprised when a “small” move wipes their position.

Binance has a built-in futures calculator. Here’s how to use it — and how to do the calculations yourself so you always know your exact risk.

Accessing the Calculator

On the Binance futures trading page:

Click the calculator icon (usually in the top-right area of the trading panel)
Select the calculation type: PnL, Target Price, or Liquidation Price
Enter your parameters and click Calculate

Alternatively, you can calculate manually using the formulas below — which is what experienced traders do.

PnL (Profit and Loss) Calculation

The formula:

For Long positions:

PnL = Position Size × (Exit Price - Entry Price) / Entry Price

For Short positions:

PnL = Position Size × (Entry Price - Exit Price) / Entry Price

Example: BTC Long

Entry price: $60,000
Exit price: $63,000
Position size: $10,000 (at 10x leverage, margin = $1,000)

PnL = $10,000 × ($63,000 - $60,000) / $60,000
PnL = $10,000 × 0.05
PnL = $500 (50% return on $1,000 margin)

Example: BTC Short

Entry price: $60,000
Exit price: $57,000
Position size: $10,000

PnL = $10,000 × ($60,000 - $57,000) / $60,000
PnL = $10,000 × 0.05
PnL = $500 (50% return on margin)

Including fees in PnL:

Real PnL must account for entry fee, exit fee, and any funding payments:

Real PnL = Gross PnL - Entry Fee - Exit Fee - Funding Fees

Using the long example with referral + limit orders:

Gross PnL: $500
Entry fee: $10,000 × 0.016% = $1.60
Exit fee: $10,000 × 0.016% = $1.60
Funding (held 2 days, 6 payments × 0.01%): $10,000 × 0.06% = $6.00
Real PnL: $500 - $1.60 - $1.60 - $6.00 = $490.80

Without discounts (market orders):

Entry fee: $10,000 × 0.05% = $5.00
Exit fee: $10,000 × 0.05% = $5.00
Funding: $6.00
Real PnL: $500 - $5.00 - $5.00 - $6.00 = $484.00

Difference: $6.80 per trade. Over 200 trades/year: $1,360 more profit with referral code XVZGVYXX + limit orders.

ROE (Return on Equity) Calculation

ROE tells you the percentage return on your actual invested margin, not the total position:

ROE = (PnL / Margin) × 100%

Or more simply:

ROE = Price Change % × Leverage

ROE examples at different leverage:

Price Change	2x Leverage	5x	10x	20x
+1%	+2%	+5%	+10%	+20%
+5%	+10%	+25%	+50%	+100%
-1%	-2%	-5%	-10%	-20%
-5%	-10%	-25%	-50%	-100% (liquidated)

This table makes it clear why high leverage is dangerous. At 20x, a mere 5% adverse move means total loss.

Margin Calculation

Margin is how much USDT you need in your futures wallet to open a position.

Initial Margin:

Initial Margin = Position Size / Leverage

Maintenance Margin:

The minimum margin required to keep the position open. This varies by position size:

Position Size (USDT)	Maintenance Margin Rate
0 - 50,000	0.40%
50,000 - 250,000	0.50%
250,000 - 1,000,000	1.00%
1,000,000+	2.50%

Example:

Position size: $20,000
Leverage: 10x
Initial margin: $20,000 / 10 = $2,000
Maintenance margin: $20,000 × 0.40% = $80

You need $2,000 to open the position, and your account must stay above $80 to avoid liquidation.

Liquidation Price Calculation

This is the most important calculation. It tells you exactly where Binance will forcibly close your position.

For Long positions (Cross Margin):

Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance Margin Rate)

For Short positions (Cross Margin):

Liquidation Price = Entry Price × (1 + 1/Leverage - Maintenance Margin Rate)

Examples: BTC Long at $60,000

Leverage	Liquidation Price	Distance from Entry
2x	~$30,300	-49.5%
3x	~$40,400	-32.7%
5x	~$48,240	-19.6%
10x	~$54,240	-9.6%
20x	~$57,240	-4.6%
50x	~$58,896	-1.8%
100x	~$59,460	-0.9%

Cross vs Isolated Margin:

Cross Margin: Your entire futures wallet balance is used as margin. Liquidation is less likely, but if it happens, you lose your entire futures balance.

Isolated Margin: Only the margin allocated to this specific position is at risk. Liquidation happens sooner, but your loss is limited to that position’s margin.

Recommendation: Use Isolated Margin for individual trades. It limits your risk per position and prevents a single bad trade from draining your entire futures wallet.

Target Price Calculation

If you want to know what price is needed to achieve a specific ROE:

For Long:

Target Price = Entry Price × (1 + Target ROE / Leverage)

For Short:

Target Price = Entry Price × (1 - Target ROE / Leverage)

Example: 50% ROE target on BTC Long at $60,000, 10x leverage:

Target Price = $60,000 × (1 + 50% / 10)
Target Price = $60,000 × 1.05
Target Price = $63,000

BTC needs to move just 5% for you to double half your margin at 10x leverage.

Complete Pre-Trade Checklist

Before every futures trade, calculate:

Position size: Based on your risk tolerance (max 2% of account per trade)
Margin required: Position size / leverage
Liquidation price: How far can price move against you?
Stop-loss placement: Must be above liquidation price (with buffer)
Risk in dollars: Position size × stop-loss distance %
Take-profit target: At least 2x your risk
Fees: Entry + exit + estimated funding
Net profit at target: Gross profit - all fees

Example pre-trade calculation:

Account balance: $5,000
Max risk: 2% = $100
Strategy stop-loss: 1.5% from entry
Leverage: 5x
Maximum position size: $100 / (1.5% × 5) = $1,333… round to $1,300
Position with leverage: $6,500
Entry: $60,000 (BTC long)
Stop-loss: $59,100 (-1.5%)
Take-profit: $61,800 (+3%, giving 2:1 reward/risk)
Entry fee (limit + referral): $6,500 × 0.016% = $1.04
Exit fee: $1.04
Max loss if stopped: ~$100 (as planned)
Profit at target: $195 - $2.08 fees = $192.92

This is how professional traders approach every single position. The calculations take 2 minutes and prevent catastrophic errors.
