Perpetual future contracts brings revolution in the futures market with endless limit of future contract. For making the contract with endless expiry date, the concept of Funding Rate came into existence. Under this mechanism the buyer or seller will either pay or receive funding on periodic bases.
It is consists of two components-
a)
The Interest rate b)
Premium Basically on Binance futures, the Interest rate is 0.03% per day (recalculated three times in 8Hrs circles of 0.01% each)and the premium varies with the mark price to prevent the increasing difference between the prices of perpetual contract price and spot market.
Here shows the funding rate and countdown period in the image when it is on marked price.
Funding rate includes Premium the price also

Example of profit or loss due to Funding rate to the traders- If the traders gets into the long position at $10 and its on $11 after 8hrs, so the long position holder trader has to pay funding rate to the short position holder, but after that if the price goes down to less than $10 , then the short position holder has to pay funding rate to prevent the lasting divergence of the price in both the markets.
So, with this mechanism crypto traders get rid of traditional future contracts with specific expiry date
