You open a futures position, watch the price move in your favor, yet your P&L shrinks. What gives? More often than not, the culprit is the funding rate — that periodic payment between longs and shorts that quietly eats into your account. I’ve seen traders blow up accounts not because they got the direction wrong, but because they ignored this cost. Let’s break down the most common mistakes people make with funding rates and how to avoid them.
Key Takeaways
- Funding rates represent the cost of holding a perpetual futures position and can significantly eat into profits, especially on high-leverage trades.
- A common mistake is entering a trade without checking the current funding rate, which can lead to paying 0.1% or more every 8 hours on large positions.
- Holding positions during extreme funding rates (above 0.1% or below -0.1%) is a high-risk strategy that often leads to liquidation from funding costs alone.
- Using the funding rate as a contrarian signal without considering broader market trends can lead to missed opportunities or premature exits.
- Proper risk management includes factoring funding costs into your stop-loss and take-profit calculations, not just the entry price.
What Exactly Is the Funding Rate — and Why Should You Care?
Before we dive into the mistakes, let’s get crystal clear on what we’re dealing with. The funding rate is a mechanism used by perpetual futures exchanges like Binance, Bybit, and dYdX to keep the contract price anchored to the spot price. Every 8 hours (on most exchanges), longs pay shorts — or shorts pay longs — depending on which side has more open interest.
Think of it as a rental fee for leverage. If you’re long and the funding rate is positive (meaning longs pay shorts), you’re essentially paying a premium to hold that position. Over a week, those 0.01% to 0.1% payments add up. On a 10x leveraged position, a 0.1% funding rate every 8 hours translates to 3% of your margin lost in just one week. That’s huge.
Now, here’s the kicker: most retail traders don’t even check the funding rate before opening a trade. They look at the chart, see a breakout, and jump in. But that breakout might be happening precisely because the funding rate is so high that longs are getting squeezed. Understanding this dynamic is the first step to avoiding costly mistakes.

Mistake #1: Ignoring the Funding Rate Altogether
This is the most common error I see. A trader spots a promising setup on Bitcoin — say, a bullish flag on the 4-hour chart. They open a long with 5x leverage, feeling confident. But they never glanced at the funding rate. It’s 0.05% — positive and high.
Over the next 24 hours, the price stays flat. But they’ve already paid 0.15% in funding fees (three payments of 0.05%). On a $10,000 position with 5x leverage (so $2,000 margin), that’s $15 gone. Doesn’t sound like much? Over 30 days of holding, that’s $450 — or 22.5% of their margin. The price didn’t move against them, but they lost a fifth of their capital.
The fix is simple: always check the funding rate on your exchange’s futures page before entering. Most exchanges display it prominently. If it’s above 0.01% or below -0.01%, ask yourself: “Am I getting paid or paying to hold this position?”
How to Check and Interpret Funding Rates
Every major exchange provides a funding rate indicator. On Binance, it’s right next to the order book. On Bybit, it’s in the “Perpetuals” tab. You’re looking at two numbers:
- Current Funding Rate: What you’ll pay/receive at the next settlement (usually every 8 hours).
- Predicted Funding Rate: What the next rate is likely to be, based on the current premium between futures and spot.
As a rule of thumb: rates between -0.01% and +0.01% are neutral. Rates above +0.05% are expensive for longs. Rates below -0.05% are expensive for shorts. Anything above +0.1% or below -0.1% is extreme and often signals an overcrowded trade.
Mistake #2: Using Excessive Leverage Without Factoring in Funding Costs
This one hurts. A trader opens a position with 20x or 50x leverage, thinking they only need a small move to profit. But they forget that funding rates are applied to the total position size, not just the margin. So on a $10,000 position with 50x leverage (requiring only $200 margin), a 0.1% funding fee is $10 every 8 hours. That’s 5% of their margin gone in a single payment.
If the price doesn’t move in their favor within the first few hours, they could get liquidated purely from funding costs. I’ve seen this happen repeatedly with altcoin futures, where funding rates can spike to 0.2% or more during mania phases.
The solution: when calculating your liquidation price, include an estimate of funding costs. Most exchanges don’t factor this into their liquidation price display — it’s on you. A good rule is to add 2-3 funding periods’ worth of costs to your liquidation calculation. So if you’re using 10x leverage, assume you’ll lose an additional 0.5-1% of your margin per day in funding.

Mistake #3: Treating High Funding Rates as a Contrarian Signal
There’s a popular trading strategy: when funding rates are extremely high (longs paying shorts), go short. When they’re extremely negative (shorts paying longs), go long. The logic is that the crowded trade will eventually reverse. And sometimes, it works.
But here’s the problem: high funding rates can persist for days or even weeks during strong trends. In a bull market, funding rates can stay above 0.05% for months. Going short just because funding is high is like catching a falling knife. You might be right eventually, but you’ll get cut badly in the meantime.
Take the 2021 bull run in Bitcoin. Funding rates were consistently positive, often above 0.05%, for weeks on end. Traders who shorted based on funding alone got destroyed as Bitcoin went from $40,000 to $60,000. The funding rate was a signal of demand, not a reversal indicator.
A better approach: use funding rates as one input, not the sole decision-maker. If funding is extreme AND the price is at a key resistance level with bearish divergence on the RSI, then a reversal trade has merit. But don’t trade against the trend based solely on funding.
Mistake #4: Ignoring the Funding Rate When Scalping or Day Trading
You might think funding rates only matter for swing traders or position traders who hold overnight. Not true. Even scalpers need to be aware, especially on altcoins.
Here’s a scenario: you enter a long on a small-cap altcoin futures contract with 1-minute scalping. You plan to hold for 5-10 minutes. The funding rate is 0.15% and settles in 2 hours. You might think, “I’ll be out before settlement.” But if the trade goes against you and you hold longer than planned — or if you get stuck in a weekend gap — that funding fee hits.
And here’s a dirty secret: some exchanges charge funding every 8 hours, but the rate can change with every block or minute on decentralized exchanges. On dYdX, for example, funding is paid continuously. If you’re scalping with high leverage, continuous funding can add up fast.
The fix: for short-term trades, avoid contracts with extreme funding rates. If you must trade them, set a strict time limit and a stop-loss that accounts for potential funding costs if you’re forced to hold.
Mistake #5: Not Considering Funding Rate in Position Sizing
Position sizing is about more than just how much you’re willing to lose. It’s also about how much you’re willing to pay to hold the position. Many traders set their position size based on a percentage of their account and a stop-loss distance, but they completely ignore funding costs.
Let’s say you have a $10,000 account and you’re comfortable risking 2% ($200) per trade. You find a setup with a stop-loss 2% away, so you open a $10,000 position (1x leverage). But the funding rate is 0.05% every 8 hours. If you hold for 3 days, you’ll pay 0.45% in funding — that’s $45, or nearly a quarter of your total risk budget. Suddenly, your risk-reward ratio is worse than you calculated.
The correct approach: include estimated funding costs in your position size calculation. If you expect to hold for 3 days and the funding rate is 0.05% per 8-hour period, add 0.45% to your total cost. Then adjust your position size so that total cost (stop-loss + funding) stays within your risk budget.
Frequently Asked Questions
How often is the funding rate paid?
On most centralized exchanges like Binance, Bybit, and OKX, funding is paid every 8 hours (usually at 00:00, 08:00, and 16:00 UTC). On decentralized exchanges like dYdX, funding is paid continuously with each block. Always check the specific exchange’s schedule.
Can the funding rate be negative?
Yes. When shorts outnumber longs, the funding rate becomes negative, meaning shorts pay longs. This often happens during sharp downtrends or when the market is heavily bearish.
Does the funding rate affect spot prices?
No. The funding rate only affects perpetual futures contracts. Spot prices are determined by supply and demand on spot markets. However, extreme funding rates can lead to arbitrage activity that indirectly affects spot prices.
What is a “normal” funding rate?
For major cryptocurrencies like Bitcoin and Ethereum, a normal funding rate is between -0.01% and +0.01% per 8-hour period. For altcoins, it can be higher — typically between -0.05% and +0.05%.
Can you make money from funding rates?
Yes. If you’re on the receiving end of funding (shorts during positive rates, longs during negative rates), you earn the fee. Some traders use a “funding rate arbitrage” strategy where they hold a spot position and a short futures position to collect funding without directional risk. However, this is capital-intensive and not risk-managed.
How does leverage affect funding costs?
Funding is charged on the total position size, not the margin. So higher leverage means the same dollar cost but a larger percentage of your margin. For example, a 0.1% funding fee on a $10,000 position costs $10 regardless of leverage, but on 10x leverage ($1,000 margin), that’s 1% of your margin. On 50x leverage ($200 margin), it’s 5%.
Key Risks to Consider
Funding rate trading is not a guaranteed strategy. The biggest risk is that extreme funding rates can persist much longer than expected. During the 2021 altcoin season, some tokens maintained funding rates above 0.2% for weeks. Traders who tried to short these tokens based on funding alone got liquidated repeatedly as prices continued to climb.
Another risk is slippage and exchange-specific issues. Some exchanges adjust funding rates dynamically based on market conditions, and the “predicted” rate can change suddenly. Additionally, during periods of high volatility, funding settlements can cause price wicks that trigger stop-losses. This is especially common on smaller exchanges with lower liquidity.
Finally, remember that funding costs are a tax on leverage. If you’re consistently paying high funding rates, you’re bleeding capital even in sideways markets. Over a year, a 0.05% average funding rate costs roughly 55% of your position size in fees. That’s unsustainable for most traders. Always factor these costs into your overall strategy.
