What Are Perpetual Contracts? A Complete Guide
A perpetual contract (also called a "perp" or "perpetual swap") is a type of derivative that lets you trade the price of a cryptocurrency without owning it and without an expiration date.
Unlike traditional futures contracts that settle on a specific date, perpetual contracts can be held indefinitely. This makes them the most popular trading instrument in crypto — accounting for over 60% of all crypto trading volume.
Why "perpetual"? Traditional futures expire quarterly. Crypto traders wanted a way to hold leveraged positions without constantly rolling contracts to the next expiration. Perpetual contracts solve this by replacing expiration dates with a funding rate mechanism that keeps the contract price anchored to the spot price.
Perpetual contracts were pioneered by BitMEX in 2016 and have since become the standard across every major crypto exchange including Binance, Bybit, OKX, and Bitget.
How Perpetual Contracts Work
Trading a perpetual contract is conceptually simple: you speculate on whether a cryptocurrency's price will go up (long) or down (short), using leverage to amplify your position.
Deposit Margin
You deposit collateral (usually USDC or the underlying crypto) into your futures wallet. This is your margin — the capital backing your positions.
Choose Your Pair & Leverage
Select a trading pair (e.g., BTCUSDC) and set your leverage. Higher leverage means more exposure but higher liquidation risk.
Open a Position
Go long if you expect the price to rise, or short if you expect it to fall. Your position size = margin × leverage.
Funding Rates Are Exchanged
Every 8 hours, a funding payment is exchanged between longs and shorts. This keeps the perpetual price close to the spot price.
Close Your Position
Close anytime to realize your profit or loss. There's no expiration — you can hold for seconds, hours, weeks, or months.
💡 Example: You deposit $500 and open a 20x long on BTCUSDC at $60,000. Your position size is $10,000 (≈0.167 BTC). If BTC rises 3% to $61,800, you profit $300 (60% return on margin). If it drops 3%, you lose $300. A 5% drop would liquidate you entirely.
Funding Rates Explained
The funding rate is the mechanism that keeps perpetual contract prices anchored to the spot market price. Without funding rates, the perpetual price could diverge significantly from the actual asset price.
📈 Positive Funding Rate
Perpetual price is above spot price (bullish market). Longs pay shorts. This incentivizes more short positions to push the perpetual price down toward spot.
📉 Negative Funding Rate
Perpetual price is below spot price (bearish market). Shorts pay longs. This incentivizes more long positions to push the perpetual price up toward spot.
| Detail | Value |
|---|---|
| Payment Frequency | Every 8 hours (00:00, 08:00, 16:00 UTC) |
| Typical Range | −0.01% to +0.03% per 8 hours |
| Annualized Impact | Can exceed 30%+ in extreme markets |
| Calculation | Funding = Position Size × Funding Rate |
💡 Example: You hold a $10,000 long position with a 0.01% funding rate. You pay $1.00 every 8 hours ($3/day or ~$1,095/year). In a bull market with 0.05% rates, that jumps to $5 every 8 hours ($15/day).

Leverage & Margin
Leverage lets you control a position larger than your actual capital. With 5x leverage, $2,000 controls a $10,000 position. This amplifies both profits and losses proportionally.
Isolated Margin
Only the margin allocated to a specific position is at risk. If the position is liquidated, only that margin is lost — your remaining balance is safe. Recommended for beginners.
Cross Margin
Your entire futures balance is used as margin for all open positions. This reduces liquidation risk for individual positions but puts your full balance at risk if a position goes badly wrong.
| Leverage | Margin ($1,000) | Position Size | Liquidation Move |
|---|---|---|---|
| 2x | $1,000 | $2,000 | ~50% |
| 5x | $1,000 | $5,000 | ~20% |
| 10x | $1,000 | $10,000 | ~10% |
| 25x | $1,000 | $25,000 | ~4% |
| 50x | $1,000 | $50,000 | ~2% |
| 100x | $1,000 | $100,000 | ~1% |
Liquidation Mechanics
Liquidation occurs when the market moves against your position enough that your margin can no longer cover the losses. The exchange automatically closes your position to prevent further losses.
How Liquidation Works
- You open a leveraged position with initial margin
- The market moves against you — your unrealized loss grows
- When unrealized loss approaches your margin, the exchange issues a margin call (or auto-liquidates)
- Your position is forcefully closed at the bankruptcy price
- Remaining margin (if any) is returned; otherwise, the insurance fund covers the deficit
Liquidation Price Formula (Simplified)
Long: Liquidation Price = Entry Price × (1 − 1/Leverage)
Short: Liquidation Price = Entry Price × (1 + 1/Leverage)
Note: Actual liquidation prices include maintenance margin, fees, and funding. Use our Liquidation Calculator for precise results.
💡 How to avoid liquidation: Use low leverage, set stop-loss orders, use isolated margin mode, and never risk more than 1–2% of your account on a single trade.
Perpetual vs Quarterly Futures
Understanding how perpetual contracts differ from traditional quarterly futures:
| Feature | Perpetual Futures | Quarterly Futures |
|---|---|---|
| Expiration | None — hold indefinitely | Fixed date (e.g., every 3 months) |
| Price Tracking | Funding rate mechanism | Natural convergence at expiry |
| Funding Fees | Every 8 hours | None |
| Premium/Discount | Minimal (funding corrects it) | Can trade at significant premium |
| Liquidity | Very high | Moderate |
| Best For | Short-term to medium-term trading | Hedging, basis trading |
| Complexity | Moderate | Lower (no funding to manage) |
Trading Tips for Perpetual Contracts
✓ Start with isolated margin
With perpetual contracts, isolated margin confines each position's collateral separately — so a single bad trade can't drain funds earmarked for other positions.
✓ Keep leverage low (2x–5x)
Higher leverage dramatically narrows the gap between your entry and liquidation price. Master the basics before increasing leverage.
✓ Monitor funding rates before opening positions
High positive funding means it's expensive to hold longs. Sometimes it's more profitable to trade in the direction that earns funding.
✓ Always set a stop loss
A stop loss automatically closes your position at a preset price, preventing catastrophic losses from sudden market moves.
✓ Account for funding in your P&L
Funding payments add up quickly. A position with great price action can still lose money if funding rates eat into profits.
✓ Use the Liquidation Calculator
Before every trade, check your exact liquidation price. This tells you how much adverse movement you can withstand.
Frequently Asked Questions
What is a perpetual contract in crypto?
A perpetual contract (or 'perp') is a type of futures contract that has no expiration date. Unlike traditional futures that settle on a specific date, perpetual contracts can be held indefinitely. They use a funding rate mechanism to keep the contract price aligned with the spot price of the underlying asset.
How do funding rates work?
Funding rates are periodic payments exchanged between traders holding long and short positions on <strong class="text-foreground">perpetual futures contracts</strong>. Unlike traditional futures that expire on a set date, perpetual contracts have no expiry — so exchanges use funding rates to keep the contract price aligned with the underlying spot price.
Can you get liquidated on a perpetual contract?
Yes. Because perpetual contracts use leverage, your position can be liquidated if the market moves against you enough to deplete your margin. The higher your leverage, the smaller the adverse price move needed to trigger liquidation.
What is the difference between perpetual and quarterly futures?
Perpetual futures have no expiration and use funding rates to track spot prices. Quarterly futures expire on a set date (e.g., every 3 months) and settle at the spot price on expiration. Quarterly contracts may trade at a premium or discount to spot without funding rate adjustments.
Are perpetual contracts available for all cryptocurrencies?
Most major exchanges offer perpetual contracts for popular cryptocurrencies like BTC, ETH, SOL, and XRP. However, smaller altcoins may only have limited perpetual markets or none at all. Binance and Bybit offer the widest selection.
What leverage is available on perpetual contracts?
Leverage varies by exchange and trading pair. Major pairs like BTCUSDC typically offer up to 125x leverage on Binance, while smaller altcoin pairs may be limited to 20x–50x. Beginners should always start with low leverage (2x–5x).
Do I own the cryptocurrency when trading perpetual contracts?
No. Perpetual contracts are derivatives — you're trading a contract that tracks the price of the cryptocurrency, not the asset itself. You never own or take delivery of the underlying crypto.
