What is funding rate in perpetual futures?

Funding rate is a periodic payment between long and short traders to keep the perpetual contract price close to spot. If funding is positive, longs pay shorts. If negative, shorts pay longs. Typically settled every 8 hours. Rates range from -0.1% to +0.1% per period.

What is the difference between ROE and ROI in futures?

ROE (Return on Equity) measures profit relative to your margin/collateral. ROI measures profit relative to total position size. With 10x leverage, a 5% ROI equals 50% ROE. Exchanges typically display ROE since it reflects actual return on your deposited capital.

How do maker and taker fees work?

Maker fees apply to limit orders that add liquidity to the order book. Taker fees apply to market orders that remove liquidity. Maker fees are typically lower (0.01-0.02%) than taker fees (0.04-0.06%). Some exchanges offer negative maker fees (rebates) for high-volume traders.

How does funding rate affect profitability?

Funding can significantly impact profitability for positions held over multiple funding periods. At 0.01% per 8h (typical), that's 0.03%/day or ~11%/year. A leveraged long during bullish sentiment (positive funding) pays this cost continuously, eating into profits.

Holding Period Analysis — Funding Impact

How funding rate erodes or adds to your P&L over time (assuming same entry/exit price):

Hold Time	Funding Periods	Funding Cost	Trading Fees	Total Cost	Break-Even Move

P&L at Different Exit Prices

Exit Price	Change	Gross P&L	Fees	Net P&L	ROE

Disclaimer: This calculator provides estimates. Actual P&L depends on execution slippage, real-time funding rates (which change every 8h), and exchange-specific margin requirements. Funding rates shown are static estimates — check your exchange for current rates. Futures trading with leverage is extremely risky. This is not financial advice.
