If you have spent any time on a crypto exchange, you have seen perpetual contracts and a small number called the funding rate ticking next to the price. Most traders ignore it, then wonder why a position quietly bleeds money even when the price barely moves. This guide explains what perpetual futures are, how funding works, and why it matters for what you actually pay to trade.

A traditional futures contract has an expiry date: you agree to buy or sell an asset at a set price on a set day, and it settles then.
A perpetual future removes the expiry. You can hold the position as long as your margin covers it. That is convenient, but with no settlement date to pull the contract price back in line with spot, the two could drift apart. Exchanges solve this with the funding rate.
The funding rate is a small payment exchanged directly between traders, usually every 8 hours, to keep the perpetual price close to spot.
When the perpetual trades above spot, funding is positive and longs pay shorts. When it trades below spot, funding is negative and shorts pay longs. Nobody pays the exchange for funding; it is a transfer between traders that nudges the price back toward spot.
Say you are long $10,000 of a BTC perpetual and funding is +0.01% for the period. You pay $10,000 x 0.01% = $1.00 to the shorts this period.
That looks tiny, but funding is charged every 8 hours, three times a day. In a hot market it can spike to 0.05%-0.1% per period. At 0.05% three times a day, that is about $15 a day, or roughly $450 a month, just to hold the trade, on top of your trading fees.
Most traders obsess over entry and exit and forget the two ongoing costs that decide profitability: trading fees on every open and close, and funding on every period you hold.
You cannot avoid funding entirely, but trading fees are far more controllable than people think. The standard taker fee on most exchanges is around 0.05%-0.06% per trade, and for an active trader that is mostly overhead.
Every trade generates a fee, and a portion of that fee is paid out by the exchange as a referral commission. Normally that goes to whoever's link you signed up under, and you get nothing back.
Through an official cashback partner, that same commission returns to you instead, automatically in USDT, on every trade. For a futures trader paying funding and fees, getting a share of your fees back is one of the few cost cuts fully in your control.
