Perpetual futures funding rates: how payments work

Last updated: November 6, 2026

Perpetual futures funding rates are periodic payments between traders that help keep contracts without an expiry date close to the underlying spot-market price. As of November 6, 2026, the formula, payment interval and settlement rules depend on the exchange and contract.

How perpetual futures funding rates work

A perpetual futures contract lets traders take long or short exposure without a fixed expiry date. Unlike dated futures, it needs a mechanism to discourage its price from drifting too far from the spot index. Binance describes funding as a periodic transfer between long and short holders designed to help keep the perpetual contract near that index.

The rate’s sign determines the usual payment direction: positive means longs pay shorts, while negative means shorts pay longs. Funding is a transfer between covered positions, not a return on the position. Rates can change, and a position can lose value as the market moves.

Exchanges set their own calculation rules. Binance’s March 6, 2026 funding FAQ says its premium index uses impact bid and ask prices relative to a price index, so the calculation can reflect order-book prices rather than only the latest trade. Binance also announced a formula update effective September 18, 2025. Its stated default interest rate was 0.03% per day, or 0.01% per eight-hour interval. These are venue-specific parameters, not universal settings.

How to calculate a perpetual futures funding fee

1. Find the position value. Use the contract’s specified valuation method. An exchange may use mark price or another measure, so the displayed market price alone may not be enough.
2. Check the funding rate and sign. A positive rate normally means longs pay; a negative rate normally means shorts pay. Check the contract page or funding panel because rules can differ by pair and venue.
3. Multiply value by rate. The basic calculation is funding fee = position value × funding rate. Bybit’s guide, last updated May 12, 2026, gives this formula and an example: a 10-contract long position marked at 8,000 USDT with a 0.01% rate pays an $8 fee.
4. Check settlement timing. Binance says its default interval is eight hours, at 00:00, 08:00 and 16:00 UTC, but contract specifications set the actual schedule. A trader generally needs an open position at funding time for payment to apply. Other venues may use different intervals.

For example, a position valued at $10,000 and a rate of 0.01% produces a $1 payment using the basic formula. This is an arithmetic illustration, not a live rate or forecast. The actual amount may differ if the platform uses another valuation, rate precision or settlement procedure.

Funding rate rules differ by venue

Perpetual futures funding rates describe a general mechanism, not an industry-wide schedule. Check the contract details for the interval, rate limits, valuation method and settlement process. Product structures and access can also vary by venue and jurisdiction.

These examples show why a displayed funding rate must be read alongside contract rules. Bybit says intervals vary by trading pair and can switch to hourly settlement if a contract reaches a preset rate limit. Coinbase separates hourly calculations from twice-daily processing. Neither schedule should be assumed to apply to another exchange.

Common mistakes and risks

• Treating the rate as fixed. Funding changes over time. A rate shown now doesn’t establish what it will be at a later settlement.
• Confusing payment with trading profit. Receiving funding doesn’t prevent losses from an adverse price move. Leverage can magnify losses, and traders can lose some or all of the funds committed to a position.
• Ignoring margin effects. Bybit says an insufficient available balance may lead to a funding fee being deducted from a position’s initial margin. In isolated-margin mode, this can move the liquidation price closer to the mark price and increase liquidation risk.
• Assuming every platform uses the same formula. Intervals, caps, pricing inputs and settlement mechanics vary. Review the contract documentation, including its mark-price method.
• Overlooking platform and market risks. Derivatives involve volatility and liquidation risk, as well as exchange, custody, smart contract, regulatory and scam risks. Funding doesn’t protect against them.

Funding can affect the cost of keeping a position open, but it’s only one part of a perpetual contract’s risk. Product rules and legal access also differ by jurisdiction.

Frequently asked questions

What does a positive perpetual futures funding rate mean?

It generally means long holders pay short holders at settlement. The rate and payment amount can change, and contract rules determine how the payment is calculated.

How often are perpetual futures funding rates paid?

There is no single schedule. Binance says its default interval is eight hours, while Bybit says intervals vary by trading pair. Check the contract specification for its current schedule and any rate-limit changes.

Can I receive funding and still lose money?

Yes. A funding credit doesn’t automatically offset an unfavorable price move. Leverage, margin deductions and liquidation can create losses, and exchange or contract risks remain even when a position receives funding.
