If you’re involved in perpetual contracts, there’s a concept you absolutely need to know: what is the funding rate?

Simply put, the funding rate is like a fee exchanged periodically between long and short position holders. It functions to bridge the gap when the price of the perpetual contract diverges from the spot price.

When the funding rate is positive, people holding long positions pay fees to those holding short positions. Conversely, when it’s negative, shorts pay longs. It’s a mechanism to balance the market.

The funding rate is determined by two main factors. One is the interest rate, which reflects the borrowing costs difference between the base currency and the quote currency. The other is the premium index, which measures the deviation between the perpetual contract price and the spot price.

A positive premium indicates that the perpetual contract is trading above the spot price, showing buying pressure. Conversely, a negative premium indicates strong selling pressure.

Even though it’s called the funding rate, the calculation method varies by exchange. For example, major futures exchanges often use a fixed interest rate model, with a default rate set around 0.03% per day. This is paid in three installments every 8 hours, each about 0.01%.

Understanding how the funding rate works helps you see the costs involved in holding a position. The current rate and the time until the next payment are displayed at the top of the trading interface. Checking this regularly can help you develop better trading strategies. It’s important to review your exchange’s specific rules and use this information for effective risk management.
