Funding is a periodic payment between longs and shorts on perpetual futures. A scalper only pays or receives it if a position is open at the settlement time. Most 1m–15m trades are flat well before that, so funding is often a timing decision, not a constant cost. It becomes a real expense when you hold through settlement on size, and a useful signal when the rate is stretched. This guide shows how to calculate it, when it matters, and how to fold it into your trade plan.
TL;DR
- Funding is paid only if you hold through the settlement time. Flat before the stamp means no payment.
- Positive rate: longs pay shorts. Negative rate: shorts pay longs.
- Cost = position notional × funding rate. Compare it to your expected profit per trade, not to your account.
- Extreme funding shows crowded positioning. It can flag squeeze risk, but it is context, not an entry trigger.
- Check the exchange's rules and your US regulatory status before you scale up leveraged perpetuals.

What funding rates are and why they exist
Perpetual futures have no expiration date. Without expiry, nothing forces the contract price back to spot. Funding does that job. Perpetual futures research describes it as a periodic payment from long holders to short holders, proportional to the gap between the futures and spot price, which keeps that gap small.
CME Group explains the direction the same way: when the perpetual trades above spot, longs pay shorts. When it trades below spot, shorts pay longs.
The exchange does not keep the payment. It moves between traders. That matters for how you read it: a high positive rate means many traders are paying to stay long.
How the rate is calculated and when it is charged
Every venue has its own formula and interval. Some settle every eight hours, others every hour. Read the contract specs before you trade.
As one US example, Coinbase's US perpetual-style futures calculate the rate hourly. The calculation uses 20 measurements of the futures-to-spot price difference, taken at three-minute intervals over the past hour. Funding payments are made every hour, on the hour, between participants holding positions. The same page says accumulated funding settles into the derivatives cash account around 12 AM ET on weekdays.
Two takeaways for scalpers:
- The clock matters more than the rate. A trade that opens at 10:05 and closes at 10:50 on an hourly schedule crosses no stamp. A trade that opens at 10:55 and closes at 11:05 does.
- The rate you see is a forecast until settlement. Rates are recalculated from live price gaps, so the number on screen at entry can differ from what you pay.
The payment formula, with scalper-sized examples
The standard formula is simple. RiskDesks gives it as funding payment = position notional × funding rate. Its example: a $10,000 long at +0.01% pays $1 per eight-hour interval, while a $50,000 short at −0.03% receives $15 per interval.
Notional means the full position size, not your margin. Leverage does not shrink the payment. It only shrinks the account balance you measure it against.
Here is how the cost scales on a $10,000 long when you do hold through one settlement (our arithmetic, same formula):
| Rate at settlement | Payment on $10,000 | Payment on $50,000 |
|---|---|---|
| 0.01% | $1 | $5 |
| 0.03% | $3 | $15 |
| 0.05% | $5 | $25 |
| 0.10% | $10 | $50 |
Small numbers look harmless. The right comparison is against the trade's target. If your plan aims for a 0.15% move ($15 on $10,000) and you hold through a 0.03% settlement as a long, funding takes a fifth of the gross target. Add fees and spread and the margin thins fast.
Over longer holds the cost compounds. RiskDesks calculates that a $10,000 long held seven days at an average +0.01% every eight hours pays $21, about 0.21% of notional, before trading fees. That is swing-trade math, but it shows why a scalp that drifts into a hold is the expensive version of a scalp.
Timing: the settlement window is part of your setup
Most scalpers never think about the funding clock. Add it to your pre-trade checks:
- Note the next settlement time for the contract you trade.
- Note the current and predicted rate and which side pays.
- Count minutes to the stamp. If your usual hold is 5 to 20 minutes and the stamp is 4 minutes away, decide in advance: exit before it, or accept the payment.
- Prefer the receiving side when it fits the setup. If the rate is negative and your signal is long, you get paid to hold. It never justifies a trade without a setup, but it breaks ties between two equal signals.
On an hourly schedule, this affects roughly one in every few trades. On an eight-hour schedule, it affects very few. Check which one you are on.
Funding as a signal, not a trigger
Funding also tells you who is crowded. When the rate stays high and positive, many traders are long and paying for it. When it goes deeply negative, shorts are crowded.
Crowding adds fuel for fast moves against the majority. A Coinbase Institutional research note flags that high funding rates combined with extended open interest can be a risk if unwinding triggers cascading long liquidations.
For a scalper, that translates to practical filters:
- Fading breakouts into stretched funding. A long breakout with very high positive funding and rising open interest is more fragile than one with neutral funding. Consider smaller size or waiting for a retest.
- Respecting squeeze risk. Heavy negative funding plus a sudden push up can produce a fast short squeeze. Do not short the first green candle.
- Treating neutral funding as a non-event. When the rate sits near its baseline, drop it from your checklist and focus on structure.
Funding does not time entries. It tells you which side is more likely to get hurt if volatility arrives. Combine it with price structure and your confluence rules. Our guide on scalping confluence methods covers how to stack conditions, and advanced entry setups shows where a funding filter slots in.
Putting funding next to fees, spread and slippage
A scalp's net result is gross move minus every friction. Funding is one of four:
- Trading fees on entry and exit.
- Spread, paid every time you cross it.
- Slippage on fast fills.
- Funding, only when you cross a settlement.
Build a per-trade cost line before you judge a setup. For a $10,000 position, imagine costs of $6 in fees, $2 in spread, $2 in slippage. That is $10 before any funding, or 0.10% of notional. A 0.15% target now nets about $5. A held-through 0.03% funding payment of $3 cuts that to $2. The numbers are illustrative, but the pattern is real: the friction stack decides whether a small-target strategy survives.
The first three costs are paid on every trade. Funding is the only one you can avoid by timing. Our piece on measuring and beating spread cost walks through the spread side, and common scalping mistakes covers the habit of letting a failed scalp turn into a hold.
A simple rule set
- Size the trade so the worst-case funding payment is under a set share of the planned profit.
- Log funding separately in your journal, so you can see its true weight over a month.
- Treat any trade that crosses two or more settlements as a different strategy with different math.
Where scale-outs fit
If you take partial profit early, you shrink the position that is exposed to funding. Locking part of the trade at the first target means the remainder, not the full size, crosses the settlement. We explain the approach in our post on a scale-out indicator for 1m–15m scalpers.
Our perspective
Most scalpers treat funding as someone else's problem, a swing-trader's cost. We think it belongs in the same checklist as spread and fees.
Our approach is to keep the process mechanical. Signals that do not repaint, confirmed on candle close, give you a clean decision point. That makes it possible to plan the exit against the funding clock instead of improvising. Volatility gating helps you avoid the chop that turns a five-minute scalp into a forty-minute hold.
Confluence matters here too. Funding stretch is one more input. When it agrees with structure and momentum, conviction goes up. When it disagrees, size goes down. That is the kind of rule-based discipline our indicators and the Discord community are built to support, with all scripts open-source so you can see exactly what each condition does.
Use funding as context. Let the setup decide the trade.

US risk checks before you scalp perpetuals
Leverage and funding together can punish carelessness. Before you scale up:
- Verify registration. The CFTC advises verifying registration when someone offers virtual-currency futures or options. It also warns that leveraged futures can lead to losses beyond your initial investment, and that most virtual-currency cash markets are not supervised by a government agency.
- Read the risk disclosures. NFA guidance for CTAs says disclosures must state that futures trading can lose initial margin and additional deposited funds, that stop orders may not limit losses, and that leverage can lead to large losses. See the NFA disclosure guide.
- Know your venue's schedule. Funding interval, settlement time and calculation method differ by exchange and contract. Confirm them on the exchange's own contract page.
- Set a hard stop and a max size. A position that moves fast against you costs far more than any funding payment.
If you are unsure whether a product or platform is open to you as a US resident, ask a registered futures broker or a licensed financial professional.
Pre-trade funding checklist
- What is the funding interval for this contract?
- How many minutes until the next settlement?
- Current rate, and which side pays?
- Does my expected hold cross the stamp?
- If yes, is payment a small fraction of my target after fees and spread?
- Is funding stretched enough to suggest crowded positioning and squeeze risk?
- Does that change my size or my side?
Five seconds on this list prevents the slow leak that eats a small-target strategy. For wider context on strategy choices, see our futures trading strategies list, and for the tooling angle our post on the benefits of algorithmic trading for scalpers.
FAQ
Do scalpers pay funding on every trade?
No. Funding is exchanged between participants who hold positions at the settlement time. If you open and close between two stamps, you pay and receive nothing. Check the contract's schedule so you know where the stamps fall.
Is a negative funding rate good for longs?
It means shorts pay longs, so a long position receives a payment if held through settlement. That is a small bonus, not a reason to enter. A negative rate can also signal crowded shorts, which raises squeeze risk for anyone short.
How do I calculate what I will pay?
Multiply your position's notional value by the funding rate. A $10,000 position at 0.01% is $1, and at 0.05% it is $5. Leverage does not change the payment, because it is based on full position size, not margin.
Can funding rates predict a reversal?
Not by themselves. Stretched funding shows crowded positioning, and high rates with extended open interest can raise the risk of cascading liquidations. Treat it as context and wait for price structure and momentum to confirm before acting.
