Funding Rate on Perpetual Futures: How to Calculate What Your Position Really Costs

The funding rate is the recurring payment between the long and the short side of a perpetual contract, and on most venues it is the largest single cost of holding a position. When the rate is positive, longs pay shorts; when it is negative, the flow runs the other way. Settlement usually takes place every eight hours, and the calculation is simple: position size multiplied by the rate for that interval. Anyone using leverage pays this charge on the full notional value of the position, even though only a fraction of that sum is their own money.

That is where the misunderstanding starts, and it is the reason this article exists. A rate of 0.01 percent per interval sounds like nothing at all. Annualised, it works out at almost 11 percent of the notional value, and at ten times leverage that is the equivalent of your entire stake. A trade that gets the direction of Bitcoin right can still end the month in the red because of this charge alone.

This guide explains how the funding rate comes about, how to calculate your own payment, what the rate tells you about market sentiment, and which levers genuinely bring the cost down.<...
