Holding perpetual futures vs spot costs more after funding
The finding
A long BTC perpetual position at 0.0100% 8-hour funding costs 10.95% of notional value annually, eroding 109.5% of initial margin at 10x leverage over 365 days.
Spot trading incurs one-off execution fees without compounding holding costs.
Perpetual positions carry a liquidation threshold that permanently closes the position during drawdowns.
The math of positive funding drag
Choosing perpetual futures vs spot depends on holding duration and funding rates. A long perpetual position on Bitget BTC incurs 0.0084% every eight hours, amounting to 9.20% per year on notional exposure.
When holding spot assets, execution fees occur only at entry and exit. On MEXC spot, taker trades cost 0.0500% while maker trades cost 0.0000%. Once acquired, holding spot assets costs zero ongoing interest.
In perpetual markets, funding rates align contract prices with spot prices. When perpetual prices trade above spot, longs pay shorts every eight hours. On Bybit, BTC and SOL both carry +0.0100% per 8h rates, which equals 0.0300% daily.
For a trader holding a 100,000 USD notional BTC position with 10,000 USD collateral at 10x leverage, daily funding payments total 30.00 USD. Over 90 days, funding removes 2,700.00 USD from the margin balance. That payment represents 27.00% of the original collateral, paid entirely to maintain the position without any movement in underlying price.
Comparing perpetual futures vs spot holding costs
Venue fee structures favour futures for short-term entry, but ongoing funding reverses this advantage over time.
| Venue | Spot Maker Fee | Spot Taker Fee | Futures Maker Fee | Futures Taker Fee |
|---|---|---|---|---|
| MEXC | 0.0000% | 0.0500% | 0.0000% | 0.0200% |
| OKX | 0.0800% | 0.1000% | 0.0200% | 0.0500% |
| Bitget | 0.1000% | 0.1000% | 0.0200% | 0.0300% |
| Bybit | 0.1000% | 0.1000% | 0.0200% | 0.0550% |
Opening a 100,000 USD spot position on OKX via taker order costs 100.00 USD. Opening the same 100,000 USD perpetual position costs 50.00 USD. The futures entry is 50.00 USD cheaper initially.
However, holding the OKX ETH perpetual at +0.0100% per 8h costs 30.00 USD per day in funding. After 1.67 days or 5 funding periods, total costs on the perpetual exceed the spot execution fee.
Bybit offers the lowest long funding rate for ETH at +0.0037% per 8h (11.10 USD daily per 100,000 USD notional), while OKX and Bitget charge +0.0100% per 8h (30.00 USD daily per 100,000 USD notional). The spread between venue funding rates for ETH is 0.0063 percentage points per 8h, making venue choice critical when holding derivative contracts beyond intraday timescales.
Worth knowing
Funding rates settle directly against collateral balances every eight hours; unpaid funding reduces effective margin and brings the liquidation price closer to the current market price.
Liquidation floors versus spot balance permanence
Spot trading offers full tolerance for price drawdowns because spot balances do not have a liquidation price. A spot position can decline 90.00% in market value and remain open indefinitely until price recovers.
Perpetual contracts require maintenance margin. At 10x leverage, a 10.00% adverse price move depletes initial margin, triggering liquidation. Maintenance margin requirements force liquidation prior to total margin loss, locking in permanent capital destruction.
Compounding funding payments accelerates this failure mode. As funding payments deduct cash from the margin balance, available margin decreases continuously.
On a 10,000 USD collateral allocation supporting a 100,000 USD SOL position at 10x leverage on Bybit (+0.0100% per 8h), 90 days of funding deducts 2,700.00 USD. The effective margin drops to 7,300.00 USD. The liquidation price moves higher by 2.70%, reducing the required drawdown to trigger liquidation from 10.00% down to 7.30%.
Where this goes wrong
Sustained positive funding during a sideways market silently raises your liquidation price, making a position vulnerable to standard market volatility even without price decline.
Extreme rate skew and negative funding opportunities
Funding mechanics do not always penalise long positions. Negative funding rates require short positions to pay long holders.
On Bybit, LSK displays a negative funding rate of -0.9593% per 8h. Long positions on Bybit receive 2.8779% daily of the notional position value in funding payouts. Across Bitget (-0.6416%) and MEXC (-0.5000%), LSK funding remains heavily negative. The spread across venues reaches 0.4593 percentage points per 8h.
For XRP, Bybit charges -0.0119% per 8h, paying long holders 35.70 USD daily per 100,000 USD notional. Conversely, Bitget charges +0.0090% per 8h for XRP, costing long holders 27.00 USD daily per 100,000 USD notional.
When funding rates skew negative, perpetual contracts yield cashflow to long holders. When rates remain positive, spot holdings remain the cheaper vehicle for directional exposure lasting longer than a few days.
What to do instead
Calculate the break-even duration where cumulative funding payments exceed spot entry and exit taker fees before opening a multi-week position.
When is spot better than perpetual futures?
Spot is better for directional positions held longer than a few days when perpetual funding rates are positive. Spot eliminates 8-hour funding costs and carries no liquidation price during severe market drawdowns.
How does funding rate affect long term perpetual futures holdings?
Positive funding rates deduct cash from collateral balances every eight hours, acting as an ongoing holding cost. Over months, these payments can exceed the initial margin invested or erode capital during flat market conditions.
Do perpetual futures fees cost more than spot fees?
Initial execution fees for perpetual futures are lower than spot taker fees across major venues. However, perpetual holding costs accumulate continuously through funding rates, making perpetuals more expensive for extended holding periods.
What happens if funding rate is negative when holding a long position?
When funding rates are negative, short position holders pay long position holders every eight hours. Long perpetual holders collect cash directly into their margin balance, making the perpetual cheaper to hold than spot.
