Type a symbol like BTC ETH PEPE in the Search Token field. Select your quote currency (USDT by default). Pick a result from the dropdown, then click ⚡ Get Live Price to load the current market price from Binance Futures.

Open Price — the price at which you plan to enter the trade.
Close Price — your target exit price.
The calculator auto-detects your direction: if Close > Open → ▲ Long, if Close < Open → ▼ Short. You can also set it manually.

Invested Margin — how much of your own money you're putting in (e.g. $15). Your actual position size will be Margin × Leverage.
Hold Time — how many hours you plan to keep the position open. This determines how many funding rate charges apply (one every 8h).

Choose Market (Taker) or Limit (Maker) order type. Defaults match Binance standard rates.
Use 🟡 BNB Discount if you pay fees in BNB to apply the 25% discount automatically.
Click ↩ Reset Fees to restore defaults at any time.

Click 📊 Calculate PNL. The table shows results for all leverage levels from 1× to 100×:

• Position ($) — notional size = Margin × Leverage
• Open / Close Fee — trading commissions
• Funding Fee — cost of holding over time
• Net PNL — your actual profit or loss after all fees
• ROE — return on your invested margin in %

• Hover any ? icon for a quick explanation of that field.
• Funding fee can be negative — meaning you earn it (e.g. Short position when rate is positive).
• Higher leverage amplifies both profit and loss — a small price move can liquidate your position.
• The highlighted row (1×) shows results without leverage as a baseline.
