The funding rate in crypto is a periodic percentage used to determine payments between long and short traders in perpetual futures markets. It helps keep a perpetual contract’s price close to the underlying cryptocurrency’s spot price. The funding rate is the percentage used in the calculation; the funding fee, or funding payment, is the actual amount a trader pays or receives.
Funding is not an annual interest rate and is not an ordinary trading fee charged for executing an order. On MEXC, funding payments are exchanged directly between eligible long and short position holders. Whether you pay or receive depends on the rate’s sign and your position direction.
Key Takeaways
- A positive funding rate generally means longs pay shorts; a negative funding rate means shorts pay longs.
- For a linear USDT-margined perpetual, the basic calculation is: funding payment = position notional × funding rate.
- Funding is based on the full position value, not only the margin deposited.
- Funding intervals and settlement rules vary by platform and contract. MEXC generally uses eight-hour intervals, but traders should check the selected pair’s displayed countdown and rules.
- Funding can indicate crowded positioning, but it does not predict the next price move by itself.
Why Do Perpetual Futures Use Funding?
A traditional futures contract has an expiry date that encourages convergence toward its settlement value. A perpetual futures contract has no fixed expiry, so it needs another mechanism to discourage its price from remaining far above or below spot.
Funding provides that mechanism through periodic incentives:
- When the perpetual trades above spot, funding will often be positive. Longs pay shorts, which can discourage excess long demand.
- When it trades below spot, funding may become negative. Shorts pay longs, which can discourage excess short demand.
These incentives can help pull the perpetual price back toward the spot market. They do not force immediate convergence, and the exact rate depends on the contract’s published methodology.
Positive vs. Negative Funding Rates
| Funding rate | Long position | Short position | Common interpretation |
|---|---|---|---|
| Positive | Pays funding | Receives funding | Long exposure or a futures premium may be relatively strong |
| Negative | Receives funding | Pays funding | Short exposure or a futures discount may be relatively strong |
| Zero | No funding payment | No funding payment | No payment is due for that settlement |
Receiving funding is not guaranteed profit: the rate can change, and adverse price movement, trading fees, slippage or liquidation losses may exceed the amount received.
Funding Rate vs. Funding Fee vs. Trading Fee
- Funding rate: The percentage applied to an eligible position at a funding settlement.
- Funding fee or funding payment: The amount transferred after applying the funding rate to the position value.
- Trading fee: A separate charge associated with order execution, such as opening, increasing, reducing or closing a position.
A trader can therefore pay both trading fees and funding. Trading fees arise from executed orders, while funding may recur even when no new order is placed.
How Funding Rate Works and How Funding Fees Are Calculated
For a straightforward linear, USDT-margined perpetual contract, the simplified formula is:
Funding payment = position notional × funding rate
On MEXC, the position value for stablecoin-margined futures is based on position size and fair price at settlement. Depending on how size is displayed:
Position value = token quantity × fair price
or
Position value = number of contracts × contract size × fair price
MEXC uses the fair price—not the margin deposited—to determine position value for funding. See how MEXC distinguishes index price, fair price and last price.
Simplified Funding Fee Calculation Example
Assume a trader has a 10,000 USDT position notional and the funding rate applied for one settlement is +0.01%. This is a hypothetical example, not a live MEXC rate.
Convert 0.01% to decimal form:
0.01% = 0.0001
Then calculate the funding payment:
Funding payment = position notional × funding rate
10,000 USDT × 0.0001 = 1 USDT
With a positive funding rate:
- A long position pays 1 USDT.
- A short position with the same notional receives 1 USDT.
If the rate is −0.01%, the direction reverses:
- A long position receives 1 USDT.
- A short position with the same notional pays 1 USDT.
This matches MEXC’s published mechanics for linear stablecoin-margined perpetual futures. In live trading, fair price, position value, the settled rate, rounding and contract rules determine the result.
Position Notional Is Not the Same as Margin
Position notional is the total market exposure. Margin is the collateral supporting it.
For example, a 10,000 USDT position opened at 10× leverage may require roughly 1,000 USDT of initial margin before fees and other requirements. At 20× leverage, the same notional may require roughly 500 USDT. If the position notional remains 10,000 USDT and the funding rate is 0.01%, the simplified funding payment remains 1 USDT in both cases.
Higher leverage therefore does not independently increase funding on unchanged notional. It makes the payment larger relative to posted margin: 1 USDT is 0.1% of 1,000 USDT but 0.2% of 500 USDT. Leverage also reduces the buffer against adverse price movement. See MEXC’s guide to isolated and cross margin.
When Are Funding Fees Paid or Received?
Funding is settled at specified timestamps, and the schedule is contract-specific.
MEXC’s funding-rate documentation says fees are generally settled every eight hours at 00:00, 08:00 and 16:00 UTC. Times can vary by pair, and MEXC may adjust an interval. Do not assume every contract uses an eight-hour cycle.
Traders generally need an open position at settlement to pay or receive funding. MEXC states that batch processing can create a window of up to 15 seconds around settlement in which an order may or may not be included. Exiting immediately before the displayed time is therefore not a guaranteed way to avoid funding.
How to Check the Funding Rate and Countdown on MEXC
On the MEXC Futures trading page:
- Open the relevant perpetual futures pair.
- Find the Funding Rate/Countdown field above the chart.
- Check both the displayed rate and the time remaining until settlement for that specific pair.
- Use MEXC’s Funding Rate History page to review completed settlements, switching to the relevant contract.
The displayed rate is not necessarily fixed. MEXC says it can adjust with market conditions, so the settled rate may differ from an earlier display. Historical records show completed rates; the live display helps estimate the upcoming payment.
For actual records on the web, go to Orders → Funding Fees. In the app, go to Profile → Transactions → Futures Orders → Capital Flow, then filter for Funding Fee.
How Repeated Funding Affects Holding Costs
A perpetual position can remain open across several settlements. If the example position paid 1 USDT at each of three settlements, total funding paid would be 3 USDT. This is only an illustration: the rate, notional and interval may change, and the payment direction can reverse.
Repeated payments matter most when a position is held for a long period, notional is large or the rate remains elevated. Traders should estimate funding alongside entry and exit fees, spread, slippage and potential losses—not as an isolated number.
What Can Crypto Funding Rates Tell Traders?
A positive crypto funding rate can suggest strong demand for leveraged longs or a perpetual premium. A negative rate can suggest stronger short demand or a discount.
Funding does not reveal why positions exist. Traders may be hedging, running market-neutral strategies or arbitraging venues. Liquidity, volatility and contract methodology also influence rates.
A high positive funding rate does not mean price must fall, just as a deeply negative rate does not guarantee a rally. Crowded positioning can increase squeeze or reversal risk, but strong trends can continue while funding remains elevated. Funding is best used with price structure, volume, open interest, liquidity and risk management rather than as a standalone prediction signal.
Frequently Asked Questions
Who pays funding when the funding rate is positive?
Long position holders generally pay short position holders when the funding rate is positive, provided both sides are eligible at settlement.
Can you receive funding fees on a short position?
Yes. A short position generally receives funding when the rate is positive. If the rate is negative, the short generally pays instead. Receiving funding does not guarantee the overall trade will be profitable.
How often are crypto funding fees charged?
It depends on the platform and contract. MEXC generally settles funding every eight hours, but some pairs use different intervals or schedules. Check the funding countdown and rules for the selected pair.
Does leverage affect funding fees?
Funding is based on position notional, not only the deposited margin. Changing leverage without changing notional does not independently change the funding payment, although it changes the payment’s size relative to margin and affects liquidation risk.
Do spot trades have funding fees?
No. Spot trades do not use perpetual futures funding. Spot traders may still pay trading fees or other applicable charges.
Does a high funding rate mean the price will fall?
No. A high positive rate may indicate crowded long positioning, but it does not reliably predict a decline. Funding should be considered with other market and risk indicators.
