How to Compare Funding Rates Across Different Settlement Intervals
Use the annualized percentage rate (APR) for a uniform conversion. Whether your platform settles every 1 hour, 4 hours or 8 hours, converting all rates into an annualized percentage lets you compare them directly.
Step 1: Find your platform's current funding rate and settlement interval
What to do: Check the current contract's "funding rate" figure and "settlement interval" on the trading interface or the contract specifications page.
How to do it:
Funding rates are usually displayed as a percentage. Major CEXs like Binance, Bybit, and OKX default to an 8‑hour settlement interval. A rate of 0.01% means you pay 0.01% of the notional position value every 8 hours.
DEX platforms such as Hyperliquid and dYdX settle every hour.
If the interface only shows a countdown to the next settlement, you can work backwards to deduce the interval.
Done when: You have two numbers clearly in hand – the current funding rate (e.g., 0.01%) and the number of hours between settlements (e.g., 8 hours).
Key reminder: The rate you are looking at is a "per-period" rate, not a daily rate. Comparing this raw number directly across platforms is misleading: a smaller number does not necessarily mean a lower cost because the settlement interval might be shorter.
Step 2: Convert the per-period rate into a daily rate
What to do: Convert the "per-period" rate into a "daily" rate.
How to do it:
Formula: Daily rate = Per-period rate × (24 hours ÷ settlement interval in hours)
Example:
Platform A: per-period rate 0.01%, settled every 8 hours. Daily rate = 0.01% × (24÷8) = 0.01% × 3 = 0.03%.
Platform B: per-period rate 0.00125%, settled every hour. Daily rate = 0.00125% × (24÷1) = 0.03%.
Done when: You have the "daily cost" as a uniform baseline.
Step 3: Convert the daily rate into an annualized percentage rate (APR)
What to do: Scale the daily rate up to a year so you get a directly comparable annualized percentage.
How to do it:
Formula: APR = Daily rate × 365
Continuing the example: 0.03% × 365 = 10.95%. Although the two platforms have different settlement intervals and per-period rates, their annualized costs are exactly the same.
OKX's official guidance for funding rate arbitrage uses a similar approach, converting historical funding rates into APR for apples-to-apples comparison.
Done when: You have a percentage figure such as "10.95% APR" – this is the unified metric you can use to compare across platforms.
Step 4: Use the standardized figure to make decisions
What to do: Based on the APR you've calculated, assess your holding cost or arbitrage opportunity.
How to do it:
Case A – You are a position holder: Compare the APR with the cost of capital from other sources (e.g., borrowing rates, stablecoin yield). If the annualized cost of holding a long position is 10.95% while your USDT deposit yield is only 5%, then the holding cost is notably high.
Case B – You are engaging in arbitrage: When the annualized funding rate gap between two platforms is large enough to cover trading fees and slippage – for instance, an annualized difference of more than 10% – only then is cross-platform arbitrage worth considering.
Done when: You have made a judgment based on the annualized figure – continue holding, switch platforms, or wait on the sidelines.
Prerequisites
Before you start the conversion, make sure you can find the "funding rate settlement frequency" (funding interval) on the trading interface or in the platform's help center. Most platforms clearly state this on the contract specifications page.
Common Mistakes
The most common mistake is comparing raw per-period rates across platforms directly. For example, looking at Hyperliquid's 0.001% per hour and Binance's 0.01% per 8 hours side by side and thinking 0.001% is much smaller. In reality, the two can correspond to exactly the same annualized cost. Another frequent oversight is ignoring the upper and lower caps that platforms impose on funding rates during extreme market conditions – these caps can limit your actual cost or gain.
Risk Disclaimer
Funding risk: Funding rates are dynamic. An annualized 10.95% today does not mean the same number tomorrow. If market direction reverses, the rate can flip from positive to negative, turning your funding income into an expense.
Account risk: Cross-platform arbitrage requires holding positions on both sides simultaneously. If price movements cause one side to be liquidated, the other side becomes exposed to one‑directional risk.
Regulatory risk: None.
Signs you have done it correctly: When you plug data from different platforms into the formulas, you can accurately calculate each one's annualized percentage and know exactly the difference between those percentages. Next step: If you hold a position, compare the calculated annualized funding rate with your expected return. If the holding cost exceeds your return expectation, either reduce leverage, consider moving to a platform with lower fees, or go short.
