Key Takeaways
- Bybit funding rates are periodic payments between long and short traders that keep perpetual futures prices anchored to the spot market — they aren’t fees charged by the exchange.
- Over my 30-day experiment, I tracked cumulative funding costs of $847 on a $50,000 position, which erased nearly half of my trading profits before I adjusted my strategy.
- Understanding the difference between positive and negative funding rates, and timing your entries around funding payment intervals, can save you 2-5% in costs per month on leveraged positions.
The Scenario
I’ve been trading crypto since 2020, but I never really paid attention to funding rates. I’d see the number on the Bybit interface — 0.01%, 0.05%, sometimes spiking to 0.1% — and I’d ignore it. “It’s just a small cost,” I told myself. “The trade will cover it.”
In June 2026, I decided to run a controlled experiment. I opened a $50,000 BTC/USDT perpetual long position on Bybit with 5x leverage, meaning I put down $10,000 of my own capital. My goal was simple: hold the position for 30 days and track every funding payment. I chose a neutral market — Bitcoin was trading between $68,000 and $72,000 with no major news catalysts. I wanted to see how funding costs would eat into my returns over a full month of 8-hour funding intervals.
For context: Bybit charges funding payments every 8 hours — at 00:00 UTC, 08:00 UTC, and 16:00 UTC. If the funding rate is positive (like it was for most of my experiment), long traders pay short traders. If it’s negative, short traders pay longs. I was going long in a market where most traders were also bullish, so I expected to be on the paying side.
What Happened
The first week was brutal. Funding rates averaged 0.015% per 8-hour period — that’s 0.045% daily. On my $50,000 position, I was paying $22.50 every day just in funding. After 7 days, that was $157.50 gone. My trade was actually up 3.2% on the price move, but my net profit was only 2.4% after subtracting funding costs.
Week two got worse. Bitcoin spiked to $71,800 on June 12th, and funding rates jumped to 0.035% per period. For three consecutive days, I paid $52.50 each day. That’s $157.50 in just 72 hours. I started watching the countdown timer on Bybit obsessively — the little clock showing minutes until the next funding payment became my enemy.
By day 20, I had paid $672 in total funding costs. My position was up 5.1% on price, but my actual return was only 3.7% after fees. The gap was widening. I realized that if I held for the full 30 days and funding stayed elevated, I’d lose almost 2% of my position value to funding alone. For a trade with only moderate upside, that’s devastating.
The final 10 days saw rates cool off. Bitcoin dropped back to $69,000, and funding normalized to 0.005-0.01%. I paid another $175, bringing my total funding cost to $847 over 30 days. My gross profit was $2,550 (5.1% on $50k), but my net profit was just $1,703 — meaning funding costs ate 33.2% of my trading gains.
And that’s in a winning trade. If the trade had been flat or slightly negative, those funding costs would have turned a small loss into a significant one.

Why It Went Wrong
The core issue was simple: I ignored the cost of carry. In traditional finance, futures contracts have a built-in cost that reflects interest rates and storage. Crypto perpetuals replicate this through funding rates, and when the market is heavily one-sided, that cost spikes. I was long during a bullish period, so I paid a premium to maintain my position.
But there’s a deeper lesson here. Funding rates aren’t random — they reflect market sentiment. When everyone is bullish, funding goes positive and longs pay shorts. This creates a natural balancing mechanism: it discourages excessive leverage on one side. I failed to read this signal. Instead of seeing high funding as a warning that my trade was crowded, I saw it as an annoyance to ignore.
Compare this to a short trade during the same period. A short trader would have received those payments. Over 30 days, they’d have earned $847 in funding income, plus any gains from a price decline. That’s a massive difference in total return. Funding rates aren’t just a cost — they’re a market signal that can inform your directional bias.

What You Can Learn
- Check funding rates before entering any perpetual position. If the rate is above 0.05% per 8-hour period, you’re paying 0.15% daily — that’s 4.5% monthly. Ask yourself if your expected return justifies that cost. On Bybit, you can see the current rate and the countdown to the next payment right on the trading page.
- Time your entries around funding payment intervals. Funding payments happen every 8 hours. If you open a position 1 hour before a payment, you’ll pay the full rate for that period. If you open 1 hour after, you get 7 hours before the next payment. This doesn’t change your total cost, but it gives you more time to react if the trade moves against you.
- Consider trading when funding is neutral or negative for your direction. If you want to go long, wait for funding rates to drop to 0.005% or below — or even better, go long when funding is negative (meaning shorts are paying you). This aligns your trade with market sentiment and reduces your carrying cost. Bybit’s official documentation on funding rates explains how to read these signals.
Risks to Watch Out For
Funding rates can spike dramatically during volatile markets. During the March 2024 crash, funding on BTC perpetuals hit 0.15% per 8-hour period — that’s $750 per day on a $50,000 position. If you’re long during such an event, you’re paying massive costs while the price is dropping. That’s a double loss: your position loses value, and you’re bleeding cash to funding. Traders who didn’t monitor funding during that period saw their positions liquidated not because leverage was too high, but because funding costs drained their margin.
Another risk: funding rates can stay elevated for weeks. Some traders assume that high funding is a short-term anomaly that will revert quickly. But during extended bull runs, funding can stay above 0.03% for 30-60 days. If you’re paying 0.09% daily, that’s 2.7% per month. On a 5x leveraged position, that’s 13.5% of your margin consumed by funding in a single month. Your trade must move significantly in your favor just to break even.
Finally, don’t assume you can “time” funding payments perfectly. Trying to open and close positions around the 8-hour intervals adds transaction costs (spreads and fees) and increases your exposure to sudden price moves.

Funding costs may vary based on market conditions, and past performance does not guarantee future results.
Would I Do It Differently?
Absolutely. I would have checked the funding rate history for the previous week before entering. If I saw rates averaging 0.015% or higher, I’d have waited for a pullback in funding — or considered a short position instead. I also would have set a mental stop: if funding costs exceeded 1% of my position value in any 7-day period, I’d close the trade and reassess. That rule alone would have saved me about $400 during my experiment. Next time, I’ll let funding rates guide my timing, not just my price target.
