Funding Rate in Dollars: What a Crypto Perp Really Costs

Funding is the cost that never shows up as a trade. No order, no fill, no confirmation — just a small line in your history three times a day. Which is exactly why it quietly eats more accounts than trading fees do.

What funding is, in one paragraph

A perpetual future never expires, so something has to keep its price tied to the real (spot) price. That something is funding: a payment between traders. When the perp trades above spot, the rate is positive and longs pay shorts. When it trades below, it flips and shorts pay longs. The exchange runs the transfer but, as BingX puts it, doesn't keep the fee — it's peer-to-peer.

The formula is simple: funding fee = position value × funding rate.

When you pay

On BingX and OKX, funding settles every 8 hours by default — 00:00, 08:00 and 16:00 UTC. You only pay (or receive) if your position is open at that exact moment.

One detail worth knowing: OKX says that when a contract's funding rate hits its cap, the settlement interval can shorten automatically to 4, 2 or even 1 hour. In a crowded, one-sided market you can end up paying more often, not just more.

The dollar table nobody shows you

All numbers below are for a $10,000 position — which is just $1,000 of margin at 10x. Rates are examples; check the live rate on your contract.

Rate 0.01% per 8h (a common calm-market level) - per settlement: $1 - per day (3 settlements): $3 - per 30 days: $90

Rate 0.05% per 8h (crowded market) - per settlement: $5 - per day: $15 - per 30 days: $450

Rate 0.10% per 8h (very one-sided market) - per settlement: $10 - per day: $30 - per 30 days: $900 — almost your entire $1,000 margin

That last row is the punchline. A trade can be right on direction for a month and still hand most of its margin to the other side in funding.

Funding vs trading fees: which one is bigger?

It depends on how long you hold.

• Trading fees are paid per fill — the taker fee is charged once when you open and once when you close. The table below shows each exchange's payback and the taker fee you effectively pay after it.
• Funding is paid per 8 hours held.

Exchange	Total rate	Welcome boost	Effective taker
BingX	60%	70%	0.0200%
OKX	50%	60%	0.0250%
MEXC	55%	65%	0.0180%

A scalper who opens and closes ten times a day pays mostly trading fees. A swing trader who holds a crowded long for two weeks pays mostly funding. Most people are somewhere in between — and underestimate the funding half.

Can you get funding back?

Honest answer: no — not through a payback. Funding never goes to the exchange, so there's no commission on it to share.

What a payback does return is part of the trading fee — the maker or taker fee on every fill. Through loweef the current combined rate on BingX is 60% of each trading fee, from the first trade. If you trade often, that's the half of your costs you can actually shrink. See what your fees would return →

For funding, the only levers are timing and positioning: knowing the settlement times, checking the current rate before you hold through one, and noticing when you're on the side that's paying.

Quick checklist before you hold a perp overnight

• What's the current funding rate, and which side pays?
• When is the next settlement (00:00, 08:00 or 16:00 UTC)?
• Has the interval been shortened on this contract?
• Multiply: position size × rate × settlements you'll hold through.
