Funding Rate Calculator: Estimate What You'll Pay or Earn on Perpetual Futures

TL;DR: The Funding Calculator in 60 Seconds

Funding payment = position × rate × time. Yieldo's funding rate calculator pulls live rates from 10 exchanges and honours each venue's real interval (4h or 8h) — so the number you see is the number you will actually pay or receive at settlement.

• The core formula is one line: Position notional × Funding Rate × (Time held / Interval hours). Everything else — APR, net-after-fees, break-even — is derived from those three inputs.
• Interval is the silent multiplier. Bybit, Binance and Bitget run 8-hour cycles; OKX drops select pairs to 4h; Hyperliquid runs a 1-hour cycle. The same rate on a 4h pair means twice the annualised cost of the same rate on 8h.
• Live rates matter because funding moves every cycle. Guessing "0.01% is normal" is fine for napkin math but not for a real trade — plug in the current rate from Yieldo's funding hub.
• Gross funding is not net funding. Round-trip taker fees (open plus close, both fills) eat 5-15% of a typical retail gross funding number. The calculator surfaces both sides.
• If you are running long-plus-short across two exchanges to harvest the spread, use the funding rate arbitrage guide. This page covers single-position P&L only.

Above: the interactive funding rate calculator. It reads the live rate for your coin and exchange, applies the venue's real interval (1h, 4h or 8h) and returns gross funding per interval, per day, per month and per year, plus a simple-annualised APR. Change position size, coin, hold duration and taker fee to model your own scenario.

What Funding Rate Actually Is — A 60-Second Refresher

A funding rate is the small, periodic payment that flows between long and short holders of a perpetual futures contract to keep the contract price glued to spot. Perps have no expiry, so exchanges use funding as the balancing force. When the perp trades above spot, longs are too eager — they pay shorts. When the perp trades below spot, shorts pay longs. If you want the full mechanics behind index price, premium index and clamp bands, the funding rate guide is the pillar; this page assumes you already know the basics and want to run the numbers on your own position.

The mechanism in one sentence

Every 4 to 8 hours (or every hour on Hyperliquid), the exchange takes a snapshot of the funding rate, checks who is long and who is short, and moves cash accordingly. If you are not in a position at the exact settlement timestamp, you neither pay nor receive — this is why some traders close a minute before a big funding hit or open a minute after a big funding credit.

Where the calculator comes in

The formula itself is trivial arithmetic. The friction is that every exchange lists a different rate, some use different intervals, and gross funding without fees is a misleading number. The Yieldo tool solves those three problems in one form so you spend two seconds instead of two minutes to answer "how much will this cost me?" You can spot-check the current market on Bybit or OKX and drop the rate straight in — trade after via Bybit or OKX.

The Funding Payment Formula — How the Number Is Built

Position × rate × time — with the venue's real interval baked in. That is the entire calculation. Written out with the exchange's actual mechanics:

Funding Payment = Position Notional × Funding Rate × (Time Held / Interval Hours)

Where:

• Position Notional is your position size in the quote currency. For a linear USDT-margined perp this is simply contracts × mark price. Notional is not your margin — a 5x leveraged $2,000 margin gives you $10,000 notional, and funding always applies to the $10,000, not the $2,000.
• Funding Rate is the decimal rate the exchange publishes for the current interval, for example 0.0001 (which prints as 0.01%). This is the composite rate — the premium component and the interest component already added — so you plug it in as-is.
• Time Held / Interval Hours converts hold duration to number of settlements. Hold a position across three 8-hour cycles and you pay or receive three funding payments; hold a position across one and you pay or receive one.

Sign convention: who pays whom

If the rate is positive, longs pay shorts (perp trades at a premium, longs are the crowded side). If the rate is negative, shorts pay longs (perp trades at a discount, shorts are crowded). The Yieldo calculator handles the sign automatically. A negative rate on a long position shows as income; a positive rate on a short shows as income; the two "positive" cases collapse into one number.

The payment-timestamp gotcha

Funding is paid only if the position is open at the exact settlement timestamp — usually 00:00, 08:00, 16:00 UTC on 8h venues (or 00:00, 04:00, 08:00, 12:00, 16:00, 20:00 UTC on 4h pairs). Close a minute early and you owe nothing; open a minute late and you owe nothing either. Traders sometimes exploit this by "sniping" negative-funding pairs — open just before settlement, close just after, keep the credit. It works, but you eat two round-trip taker fills for one funding cycle, which usually kills the P&L on anything but the most extreme negative rates. See funding as a trading indicator for the sentiment angle.

Interval Matters: 8h vs 4h — The Silent APR Multiplier

Same rate on OKX (4h) vs Bybit (8h) means twice the payments per day, and therefore twice the annualised cost. This is the single biggest source of "my broker's APR doesn't match my calculator" complaints, and it is the reason the Yieldo tool ships with an interval dropdown rather than hardcoding 8h like most competitors do.

Standard 8-hour cycle

Bybit, Binance, Bitget and (currently) Aster settle funding every 8 hours across every perpetual pair. Three payments per day, 1,095 per year. Most Gate, KuCoin and MEXC pairs also fall into this bucket, but those venues expose the real interval per contract via their APIs — Yieldo parses that value into the funding rate calculator per pair so a 4h Gate contract does not silently get treated as 8h.

4-hour exceptions

OKX has moved a growing set of pairs to a 4-hour cycle (00:00, 04:00, 08:00, 12:00, 16:00, 20:00 UTC), typically the most liquid ones — BTC, ETH, SOL and other blue chips. The same 0.01% rate on an OKX 4h pair produces 21.9% APR versus 10.95% on the equivalent 8h contract. If you routinely trade OKX perps and never adjusted your mental annualisation, you have been under-estimating your funding P&L by half. Trade after checking your rate on OKX to keep the maths honest.

Perp-DEX quirks

Hyperliquid is the only major venue on a 1-hour funding cycle — 24 payments per day, 8,760 per year. A modest 0.001% per hour rate annualises to 8.76% APR; the smaller per-cycle numbers hide larger annualised flows. Aster, marketed as an 8h/4h mix, currently reports 8h uniformly through its public feed, so the Yieldo calculator uses 8h until Aster ships the per-pair breakdown; sanity-check on the Aster app itself before opening a large position.

Hyperliquid caveat: our Hyperliquid referral bridge does not currently resolve the join-code on production, so the link falls back to app.hyperliquid.xyz without a fee rebate. You still get the same funding math — just no rebate on top.

Position × rate × time — with the venue's real interval baked in. For the deepest side-by-side between the two most-traded CEX venues, jump to the Bybit vs OKX funding comparison. And Bitget copy-traders can pull their rates via Bitget.

Worked Example 1 — Long BTC on Bybit (Positive Funding, You Pay)

Position × rate × time — with the venue's real interval baked in. This scenario mirrors what a typical retail long looks like when funding on Bybit sits at the mildly bullish end of its normal range. Numbers:

• Position notional: $10,000 (a 5x leveraged trade using $2,000 of margin)
• Venue: Bybit, BTCUSDT perpetual, 8-hour interval
• Funding rate: 0.0100% per 8h (a mild-bullish reading; BTC typically ranges 0.005-0.02% per 8h in calm markets and can spike above 0.10% during squeezes)
• Hold duration: 3 days

Step 1 — Payments per day. 24 / 8 = 3 payments per day.

Step 2 — Total payments across the hold. 3 payments × 3 days = 9 payments.

Step 3 — Per-payment cost. $10,000 × 0.0001 = $1.00 per settlement.

Step 4 — Gross funding paid. 9 × $1.00 = $9.00 out over three days.

Step 5 — Annualise (simple APR). 0.0100% × 3 × 365 = 10.95% annualised funding cost on the notional. On $2,000 of margin, 10.95% APR on the $10,000 notional works out to $1,095 per year of funding drag on the leveraged equity — roughly 55% of margin per year at that constant rate, which is why elevated funding regimes chew through leveraged longs even when price does nothing.

Step 6 — Sanity check via the calculator. Enter the same numbers into the widget above; you should see the same $9.00 gross across the 3-day hold, $3.00 per day, $90.00 per month at the constant rate and 10.95% simple APR. If the calculator returns a different figure, you probably have the wrong interval or the wrong position size (margin vs notional). Cross-check current live rates on the Bybit funding page and open your trade on Bybit once you know the number.

Live Funding Rates Today — Which Numbers to Plug In

Position × rate × time — with the venue's real interval baked in. The rate is the input you cannot fake. Below is the current top-of-book across our 10 tracked exchanges, refreshed on our standard 10-minute polling cadence.

How to read the table

Each row is a coin, and the exchange shown is the venue with the largest absolute funding rate right now — not necessarily the highest positive rate. If a coin has +0.05% on Bybit and −0.03% on Gate, the table will show the Bybit row because 0.05 > 0.03 in absolute magnitude. That is deliberate: the largest-absolute rate is the largest cash flow, and cash flow is what the calculator cares about. If you specifically want negative-only opportunities, drill into a coin page (BTC funding, ETH funding) or use the funding rate arbitrage scanner which sorts by long-vs-short spread rather than by magnitude.

Range vs snapshot

Funding is a snapshot value, not a fixed rate. The number in the widget above is the last rate the exchange published; the next one drops in 4 to 8 hours (or 1 hour on Hyperliquid). Do not model a three-week hold on today's snapshot alone — pull a range from the coin page and stress-test the calculator with both the calm and the squeeze end of that range. Altcoins on MEXC and Gate.io routinely fly higher in magnitude than blue chips; the thin-listing bonus (coins that are not on Binance or Bybit) is where most of the fat funding numbers live.

Worked Example 2 — Short ETH on OKX (Negative Funding, You Earn)

Position × rate × time — with the venue's real interval baked in. Numbers:

• Position notional: $5,000 (a 3x leveraged short using $1,667 of margin)
• Venue: OKX, ETHUSDT perpetual, 4-hour interval
• Funding rate: −0.0080% per 4h (a bearish reading; shorts are being paid to hold ETH exposure)
• Hold duration: 5 days

Step 1 — Payments per day. 24 / 4 = 6 payments per day. Notice this is double what Bybit's 8h cycle produces.

Step 2 — Total payments across the hold. 6 payments × 5 days = 30 payments.

Step 3 — Per-payment cash flow. $5,000 × 0.000080 = $0.40 received per settlement (you are short, rate is negative, so you receive).

Step 4 — Gross funding received. 30 × $0.40 = $12.00 in over five days.

Step 5 — Annualise (simple APR). 0.0080% × 6 × 365 = 17.52% annualised funding income at the constant rate — noticeably higher than Example 1's 10.95% despite a smaller per-cycle rate, purely because 4h means twice as many payments.

Reproducibility statement: the rates above are illustrative diagnostic numbers, not live snapshots. Actual live rates modelled with data available as of 15 August 2026, cross-checkable in the funding-top widget above and on the individual OKX funding page. If you want the mechanics of why negative funding shows up in the first place, the negative funding rate explained guide breaks it down; execution links via OKX and, if you prefer copy-trading, Bitget.

The Net-After-Fees Reality Check — Why Gross Funding Lies

Trading fees eat 5-15% of gross funding on typical retail positions — and on very short holds or thin-margin funding trades, fees can flip the whole trade underwater. Rate × time — but do not forget the (fees × 2). This is the layer the Yieldo funding rate calculator surfaces so you never confuse gross with net. Here is the anatomy.

Round-trip fee math

Every closed position has two taker fills — one to open, one to close — unless you post limit orders and get filled as maker. Round-trip cost is therefore notional × taker fee × 2. Using taker rates verified for August 2026:

• MEXC — 0.020% taker × 2 = 0.040% round-trip (cheapest of the top venues)
• Hyperliquid — 0.035% × 2 = 0.070%
• Binance / OKX / Gate — 0.050% × 2 = 0.100% (Binance drops to 0.045% with a BNB discount = 0.090% round-trip)
• Bybit — 0.055% × 2 = 0.110%
• Bitget / KuCoin — 0.060% × 2 = 0.120%

The default in the calculator is 0.05% (the CEX average). Replace it with your actual fee tier — high-volume traders and BNB/token holders often shave 20-40% off.

Break-even hold time

If gross funding is 0.010% per 8h on Bybit and round-trip fees are 0.110%, you need 11 cycles just to cover fees — that is 88 hours (about 3.7 days) of continuous hold before your net funding turns positive. On the same 0.010% per-interval rate on OKX's 4h cycle, you still need 11 cycles, but each cycle is half as long — so wall-clock break-even drops to 44 hours (about 1.8 days). This is why funding-collection strategies live and die on interval and fee tier, not on the headline rate.

Maker rebates change the math

Post limit orders and you may be paid to trade instead of paying. Bybit and Binance offer small maker rebates for VIP tiers; OKX and Gate charge close to zero maker on standard tier. A round-trip at 0.020% maker × 2 = 0.040% drops your break-even from 11 cycles to 4 cycles on the same 0.010% funding rate. The trade-off is fill risk — if the market runs and you never get filled at your limit, the whole strategy is moot.

Above: the calculator again — reinforce your intuition by re-running Example 1 with the taker fee toggled to 0.055% (Bybit) and then to 0.020% (MEXC). Watch the "net after fees" figure move by more than half. Full fee schedules for all exchanges live in our fees hub, and if you want a proper Bybit vs OKX teardown across trading and withdrawal, see the Bybit vs OKX fees comparison. Execution ideas — funding-hunt on Bybit, or copy-trade on Bitget, or thin-alt hunt on KuCoin where funding on smaller pairs can be materially wider.

Compounding vs Simple — How to Annualise a Funding Payment

The naive APR formula

The industry-standard annualisation — used by our calculator, by coinglass, by coinalyze and by every serious data aggregator — is simple:

APR = funding rate × (24 / interval hours) × 365

Simple annualisation ignores compounding of prior funding payments back into position size. This is deliberate, and it is correct for the default case, because the exchange does not automatically re-add funding cash flow to your margin as fresh notional.

Why compounding rarely helps

Funding is a realised cash flow, not accrued yield. Every settlement, the money either lands in your margin balance (income) or comes out of it (cost). It does not sit on the position as unrealised P&L compounding on itself. If you want to compound it, you have to manually close the position, add the funding cash to your margin, and re-open at the new (larger) notional. Most retail traders do not do this because the fee friction (two more round-trips per compounding cycle) usually eats the compound uplift.

On numeric terms: a 0.01% per 8h rate held for a year is 10.95% APR simple. The compound-equivalent (1.0001 raised to 1,095) is about 11.58% — a 63-basis-point uplift that a single extra round-trip fee (0.11% on Bybit) more than wipes out. On extreme rates the compound gap widens but so does the fee cost of harvesting it.

When compounding actually matters

The compounding case is the fully-funded delta-neutral run — long spot + short perp with the funding cash swept into fresh margin every cycle. That is the classic funding-arb trade, and the compounding uplift becomes real over long horizons. Model that construction on the funding rate arbitrage guide and, for the perp-DEX-versus-CEX variant, the CEX vs DEX funding arbitrage teardown. If you want the sentiment interpretation of high funding rather than the cash-flow angle, the funding rate trading indicator guide is the sister to read. Cross-venue coverage checks on Gate.io and thin-alt runs on MEXC round out the toolbox. Position × rate × time — with the venue's real interval baked in.

When Funding Pays vs When It Costs — A Regime Guide

Position × rate × time — with the venue's real interval baked in. But the "rate" leg is a function of market regime, not a constant. Four regimes cover most of the surface area.

Bull regime — funding trends positive, longs pay

Typical rate 0.01-0.03% per 8h across BTC/ETH; alts can push 0.05%+. Longs pay shorts, and the calculator returns cost numbers. During the early-2024 rally, BTC funding on Binance and OKX spent weeks above 0.03% per 8h — an annualised cost above 30% on the long leg. If you are levered long in a bull regime on Bybit, funding is a real drag; if you are collecting funding via delta-neutral short perp + long spot, this is the regime that pays the bills.

Bear regime — funding often negative, shorts pay

Typical rate −0.005% to −0.03% per 8h; blow-off panic can push below −0.05%. Shorts pay longs. If you are levered short, funding chews into your P&L; if you are long in a bear (contrarian), funding pays you to stay in the trade. This is a rare regime — negative-funding weeks are the minority — but they generate the fattest one-sided funding-collection numbers.

Range or quiet regime — funding near zero

Typical rate ±0.005% per 8h. Calculator returns near-zero cash flow either way. This is the boring regime that most funding-collection strategies underperform in, because you do not clear round-trip fees. Historical dataset available via the funding rate benchmark.

Blow-off or squeeze regime — funding spikes to 0.10-0.30% per 8h

Annualised 100-400% APR. These are the moments when the calculator returns numbers that look like typos. During short-squeeze events (Feb 2024, Nov 2024 spikes on BTC per public exchange data), funding briefly reached triple-digit annualised APR on select pairs. Squeeze regimes are the reason the tool exists — you need to be able to convert an eye-watering per-8h number into a per-day dollar figure before deciding to hold or close. Perp-DEX pairs show similar dynamics; see Hyperliquid vs Aster vs Lighter funding for how the three DEX venues track each other during squeezes, and BTC funding across Binance, Bybit and OKX for the CEX equivalent. Binance perp is deep enough to absorb most squeezes without extreme prints, but even Binance regularly touches the 0.05% per 8h band.

Cross-venue coverage on the perp-DEX side via Hyperliquid (with the join-code caveat noted earlier) and, for readers outside the excluded regions, Aster.

How to Use This Calculator — A 5-Step Playbook

The funding rate calculator is deliberately terse — five inputs, one output block. Here is the workflow that turns raw numbers into a trading decision.

1. Pull the live rate. Open the Yieldo funding hub (or the coin-specific pages, BTC funding / ETH funding) and read the current rate for your coin on the venue you plan to trade. Copy the rate value; note whether it is positive or negative.
2. Enter position size as notional, not margin. This is the most common mistake. Notional = contracts × mark price = the full exposure, not the collateral you posted. A 5x leveraged $2,000 trade is $10,000 notional; funding is calculated on the $10,000. If you enter $2,000 you will under-estimate cash flow by 5x.
3. Select exchange so the interval auto-fills. The calculator populates the interval based on the venue you pick — 8h for Bybit / Binance / Bitget, real interval per pair for OKX / Gate / KuCoin / MEXC, 1h for Hyperliquid. Do not manually override unless you know the pair uses a non-default interval. Interval error is a silent 2x mistake.
4. Set hold duration in hours (not days). Hours give you precision at the settlement-boundary edge — a 23-hour hold is materially different from a 25-hour hold because the 25-hour version catches an extra settlement. If the tool defaults to days, override to hours for anything under a week.
5. Read gross, then subtract fees mentally. Gross funding × 1 minus round-trip taker × 2 = net funding. For a Bybit trade: net = gross − (notional × 0.055% × 2). If net is negative you are paying more in fees than the trade earns in funding — reconsider hold length, or check whether the funding arb calculator shows a better hedged setup on the same pair. Position × rate × time — with the venue's real interval baked in, minus (fees × 2) — is the verdict formula.

Execute directly on Bybit or OKX once the numbers agree with your plan; add KuCoin to the shortlist if you want a smaller-liquidity venue that occasionally prints wider funding on the same pair.

Frequently Asked Questions

How is funding rate calculated on crypto perpetual futures?

Funding payment = position size × funding rate × (time held ÷ interval hours). For a $10,000 long at 0.01% rate held one 8-hour cycle, you pay $1.00. Yieldo's funding rate calculator automates this across 10 exchanges and their real intervals (4h or 8h). Full formula and worked examples are above.

How often is funding paid on Bybit, OKX and Binance?

Binance and Bybit pay funding every 8 hours on all perpetual pairs. OKX defaults to 8 hours but uses 4 hours on select liquid pairs (BTC, ETH, SOL and others). Hyperliquid runs a 1-hour cycle; Aster mixes 8h and 4h depending on the pair. The Yieldo calculator pulls the real interval per venue so your APR estimate is not silently wrong by 2x.

What happens if the funding rate is negative — do I pay or receive?

Negative funding means shorts pay longs. If you hold a long, you receive the payment; if you hold a short, you pay it. The calculator handles the sign automatically — a negative rate on a long position shows as income, not cost.

How much funding will I pay on a $10K BTC long held for 24 hours?

At a typical 0.01% per 8-hour rate, a $10,000 long pays 3 × $1.00 = $3.00 in 24 hours (about 10.95% annualised cost). At an elevated 0.05% per 8h during bull euphoria, the same position costs about $15 per day or roughly 55% APR. Model your exact rate in the calculator above — funding shifts every 4-8 hours. Live snapshot: 15 August 2026.

Can I earn passive income from funding rates?

Yes, but not risk-free. Delta-neutral funding arbitrage (long spot + short perp, or long perp on venue A + short perp on venue B) captures the funding while hedging price direction — typical net APR is in the high single digits to low double digits in calm markets. A one-sided short in a negative-funding regime also earns funding but keeps full price risk.

Is funding included in trading fees?

No. Funding is a separate cash flow between long and short holders every 4-8 hours; trading fees are what the exchange charges on your open and close fills. Our funding rate calculator shows gross funding; you subtract round-trip taker fees (roughly 2 × 0.055% on Bybit = 0.11% notional) to get true net.

How do I annualise a funding rate to APR?

APR = funding rate × (24 ÷ interval hours) × 365. A 0.01% rate on an 8-hour cycle annualises to 0.01% × 3 × 365 = 10.95% APR. On OKX 4h pairs, the same 0.01% rate doubles to 21.9% APR because there are twice as many payments per day. This is why interval matters more than most traders realise.

What is the difference between funding rate and interest rate on perp exchanges?

Funding rate is the long-short balancing payment (variable, based on premium of perp over spot). Interest rate is a borrow cost embedded in the funding formula (typically a fixed 0.01% per 8h component on Binance and Bybit, 0% on OKX). The rate you see in the calculator is the composite — you do not need to separate the two for cash-flow math.

Do all exchanges have the same funding rate for the same coin?

No — funding rates diverge because each exchange calculates from its own perpetual premium and its own index price. BTC on Bybit vs OKX can differ by 0.005-0.02% per cycle; altcoins on MEXC or Gate can diverge from Binance by 0.05% or more. This divergence is exactly what funding arbitrage scanners hunt. See our Bybit vs OKX funding comparison for the head-to-head.

How accurate is the Yieldo funding calculator versus the exchange's own preview?

The Yieldo funding rate calculator uses the same live funding rate the exchange publishes (polled every 10 minutes) and applies the venue's real interval, so gross funding matches to the cent. Divergence only appears when the exchange updates its rate mid-cycle — the calculator refreshes on the next poll. Snapshot: 15 August 2026.
