  • Funding fees keep perpetual futures aligned with spot prices
  • Small fees can compound into major costs over time
  • Managing funding is essential for leveraged traders

Perpetual futures are one of the most popular trading instruments in crypto. They offer leverage, flexibility, and the ability to go long or short without worrying about contract expiry. But there’s a cost many traders underestimate — funding fees.

These fees aren’t obscure or hidden, yet they often go unnoticed until profits start shrinking. Charged automatically every few hours, funding fees can quietly turn a good trade into a disappointing one. Understanding how they work — and how to manage them — is essential for anyone trading leveraged crypto products.

What Are Funding Fees in Crypto Trading?

A funding fee is a periodic payment exchanged between traders who are long and short on a perpetual futures contract. It typically occurs every eight hours, though timing can vary by exchange.

If funding is positive, long traders pay short traders. If funding is negative, shorts pay longs. The exchange simply facilitates the transfer — it doesn’t keep the fee.

The goal is simple: keep the price of the perpetual contract closely aligned with the spot market. Since perpetual futures never expire, funding fees act as a balancing mechanism to prevent prices from drifting too far in either direction.

On a single trade, the fee may seem insignificant. Over days or weeks, especially with leverage, it can materially impact performance.

How Funding Rates Are Calculated

Funding rates are not fixed fees. They change constantly based on market conditions.

Most exchanges calculate funding using two main components:

  • Interest rate: Usually a small, mostly fixed percentage.
  • Premium index: The difference between the futures price and the spot price.

When futures trade above spot, it signals strong long demand, pushing funding positive. When futures trade below spot, shorts dominate, and funding turns negative.

Each platform uses its own formula, but the logic is consistent: crowded trades become more expensive to hold. This discourages extreme imbalances and keeps prices in check.

Why Funding Fees Matter More Than You Think

Funding fees don’t hit all at once, which is why many traders overlook them. But they compound quietly.

Holding a leveraged position during a strong trend can mean paying funding multiple times a day. In sideways markets, funding can drain profits even when price barely moves. For high-leverage traders, funding costs scale with position size, increasing risk.

History offers clear examples. During hype-driven rallies, some assets have seen funding exceed 0.3% every eight hours — more than 2% per day. Traders who stayed long during those periods often lost money despite being “right” on direction.

How Funding Impacts Trading Strategies

Funding fees influence more than just costs — they shape strategy.

Short-term traders may barely feel them, but swing traders and position traders must factor funding into entries and exits. Some experienced traders even use funding strategically, taking positions where they are paid to hold risk rather than charged for it.

However, relying solely on funding income is risky. Rates can flip quickly, and sudden volatility can overwhelm small funding gains.

Smart Ways to Manage Funding Costs

Traders who last in perpetual markets actively manage funding exposure:

  • Check funding before entering a trade
  • Avoid holding high-funding positions during consolidation
  • Reduce leverage to limit fee impact
  • Time entries around funding intervals
  • Close positions if funding overwhelms trade thesis

Small adjustments can make a meaningful difference over time.

Make Funding Part of Your Strategy

Funding fees are not a flaw in crypto markets — they’re a core feature of perpetual futures. But ignoring them is costly.

Traders who understand funding gain an edge: better timing, clearer expectations, and fewer unpleasant surprises. Whether you’re scalping or holding for days, funding should always be part of the decision-making process.

In leveraged trading, what you don’t track often costs the most.
