Perpetual futures are popular because they let traders keep leveraged crypto exposure without managing an expiry date. That convenience hides a cost: funding payments. Coinbase Learn describes funding rates as a mechanism that helps keep perpetual contract prices aligned with spot markets, while Kraken’s guide emphasizes that perps let traders speculate without owning the underlying asset.
The funding payment is not a small footnote when leverage is high. If longs are crowded and the perp trades above spot, longs may pay shorts at each funding interval. If a trader holds a position through multiple intervals, the cost can reduce profit or deepen a losing trade even when the entry direction was partly right.
MetaMask’s funding guide highlights timing because strategies are affected differently depending on how often funding is paid. A short scalper, a basis trader, a hedge against spot holdings and a swing trader are not exposed to funding in the same way. The longer the holding period and the higher the leverage, the more funding behaves like interest expense.
A practical pre-trade checklist should include four questions. Is the perp premium or discount unusually large versus spot? Who is likely paying funding? How many funding windows could the trade cross? If funding spikes against the position, will the trade still meet its risk-reward threshold?
For beginners, the safest framing is simple: funding is part of the trade price, not a separate accounting detail. Use lower leverage when funding is unstable, avoid holding crowded positions through known event windows without a plan, and compare perp exposure with spot or dated futures when the carrying cost looks high.

Risk notice: Perpetual futures are leveraged derivatives. Liquidation, funding costs, exchange rules and market gaps can all create losses larger than expected.
