Perpetual futures let you increase your exposure to crypto markets without actually owning the underlying assets. Learn how they work, how they can benefit you, and how to manage their risks.

Perpetual futures, often dubbed "perpetuals" or “perps”, are one of the most dynamic instruments in the cryptocurrency trading scene. These derivatives let you bet on the price swings of cryptocurrencies without actually owning the underlying assets. And unlike traditional futures, which expire on a set date, perpetuals can be held indefinitely.
As a result, perpetual futures have become a go-to tool for savvy crypto traders who want to stay nimble and engaged without the constraints of traditional contracts.
Perpetuals can be much more than a trading tool; they offer flexibility, leverage, and the opportunity to hedge against market volatility.
These features give perpetuals several benefits over traditional futures. Both perpetuals and futures let you speculate on crypto prices with or without leverage. For a deeper comparison, see perpetual swaps vs dated futures.
Understanding the mechanics behind perpetual futures is crucial for any trader. Here’s a breakdown:
How well you understand funding rates work can make or break your perpetual trading strategy, so let’s double-click into this crucial concept.
To reiterate, funding rates ensure a perpetual contract price doesn't stray too far from the actual asset's price. While exact funding rates differ across different perpetuals, they are all periodic payments made between long and short-position holders, based on the difference between the contract and spot prices.
Thus, if the perpetual trades higher than the spot price, long holders pay a fee to short holders, and vice versa. It's a mechanism designed to keep trading balanced and prevent any wild pricing discrepancies.
Funding rates aren't just plucked out of thin air. They're calculated based on current market conditions, including how much the perpetual price deviates from the spot price, plus a little extra for interest rates. If you’re trading perpetuals, keep an eye on their funding rates. This mechanism could pay you to hold a position when market dynamics align in your favor, but high rates can turn a winning trade into a break-even deal—or worse.
The key concepts introduced above may seem a bit abstract, so let’s use a real-world example to see how they come together in an actual perpetual trade:Imagine you have $1,000 in your trading account and decide to trade Bitcoin perpetual futures with 5x leverage. This leverage means that for every $1 of your own money, you can trade $5 worth of Bitcoin. The current price of Bitcoin is $10,000.
Position Size and Leverage
With 5x leverage, your $1,000 allows you to open a position worth $5,000 (5 x $1,000). This means you can buy 0.5 BTC ($5,000 / $10,000).
Mark Price and Funding Rate
Let's assume the mark price is also $10,000 and the funding rate is 0.01% per 8 hours. Since your position is long (you're buying BTC), and the perpetual futures price is higher than the spot price, you will have to pay this funding rate to short position holders.
Margin Requirements and Liquidation
Your initial margin is $1,000, which is 20% of the total position size ($5,000). If Bitcoin’s price falls to $9,800, your position will be worth $4,900 (0.5 BTC x $9,800). Your loss would be $100 ($5,000 - $4,900), which reduces your equity from $1,000 to $900.
Let's say the maintenance margin requirement is 10%. Your maintenance margin would be $500 (10% of $5,000). If your equity falls below this, your position could be liquidated to cover losses.
Calculating Profit and Losses
If the price of Bitcoin increases to $10,500, your position would be worth $5,250 (0.5 BTC x $10,500). Your profit would be $250 ($5,250 - $5,000), resulting in a 25% return on your initial $1,000 investment.
However, you also have to pay the funding rate. If the funding rate is 0.01% per 8 hours and you hold your position for 24 hours, you pay three times (0.01% x 3 = 0.03%). On a $5,000 position, this equates to $1.50 (0.03% x $5,000). After subtracting the funding payment, your net profit would be $248.50.
While perpetuals are a powerful tool within your arsenal, all financial instruments come with certain risks and must be used carefully. If you’re considering trading crypto perpetuals, be sure to mitigate your risk by doing the following:
Whether you're a seasoned trader or a crypto newcomer, perpetuals offer a versatile way to tap into this exciting new market. But remember, in trading, as in life, there's no reward without risk — so trade wisely, start slow, and incorporate dollar cost averaging if you're just getting started.
