Crypto Funding Rate Calculator — Binance, Bybit & MEXC
Perpetual futures funding fees charge every 8 hours — a 0.1% rate looks small but costs 0.9% of your full position per day, nearly 27% per month on a leveraged trade. Enter position size, current funding rate, and planned holding periods to see exact funding cost or income before deciding to hold. Long-held perpetual positions routinely pay more in funding than they gain from price movement.

Why Use the Funding Rate Calculator?
Perpetual futures funding fees are charged every 8 hours and erode profits quickly on positions held for days. A 0.1% funding rate may look small but costs 0.9% per day — nearly 27% per month on a highly leveraged position. This calculator shows the total funding cost for your exact holding period before you decide to hold.
Formula Used
Funding Fee = Position Size × Funding Rate % | Per 8h period | Daily = Fee × 3Worked Example
$50,000 BTC perpetual long on Binance, funding rate 0.01% per 8h period, held 7 days (21 periods). Fee per period = $50,000 × 0.0001 = $5. Daily fee = $5 × 3 = $15. Total for 7 days = $5 × 21 = $105. Bitcoin must appreciate by more than $105 just to cover your funding costs — factor this into your profit target before holding multi-day perpetual positions.
How to Use the Funding Rate Calculator — Step by Step
- 1
Enter your position size
Input the total USD value of your perpetual futures position.
- 2
Enter the funding rate
Input the current funding rate percentage. Find this on your exchange — Binance shows it on the futures trading page. Typical rates are 0.01% per 8 hours.
- 3
Enter holding periods
Input how many 8-hour funding periods you plan to hold the position. 1 day = 3 periods, 1 week = 21 periods.
- 4
Check if you pay or receive
If the funding rate is positive and you are long, you pay. If negative and you are long, you receive. The calculator shows your total funding cost or income.
What Your Funding Rate Calculator Results Mean
Fee per 8-Hour Period
The funding charge or credit for one 8-hour period at your position size. Negative funding rate means longs receive payment; positive means longs pay shorts.
Daily Funding Cost
Three times the per-period fee, since most exchanges charge every 8 hours (3 times daily). This is the minimum profit your position needs per day just to stay break-even on funding.
Total Funding for Holding Period
The cumulative cost or income over your planned holding period. Compare this to your take-profit target to verify the trade remains profitable after funding is deducted.
Funding Rate Calculator — Frequently Asked Questions
Q.What is the crypto funding rate?
The funding rate is a periodic payment between long and short traders in perpetual futures markets. It keeps the perpetual contract price close to the spot price. When the rate is positive, longs pay shorts (bullish market sentiment). When negative, shorts pay longs (bearish sentiment). It is charged every 8 hours on most exchanges.
Q.How is the funding fee calculated?
Funding Fee = Position Size (USD) × Funding Rate (%). For example: $10,000 position at 0.01% funding rate = $1.00 per 8-hour period = $3.00 per day = $21.00 per week. On a leveraged position, the fee applies to the full notional value, not just your margin.
Q.What is a high funding rate?
A funding rate above 0.1% per 8 hours (0.3%/day or about 9%/month) is considered very high and suggests extreme market greed. During bull market peaks, rates can spike to 0.3–0.5% per period. High positive funding is often used as a contrarian signal — it indicates over-leveraged longs and potential for a sharp correction.
Q.How do I avoid paying funding fees?
Close your position before the funding timestamp (every 8 hours). Alternatively, open an opposite position on another exchange to hedge — this is called funding rate arbitrage. You can also trade spot instead of futures to avoid funding fees entirely.
Q.What does a negative funding rate mean for crypto traders?
A negative funding rate means short sellers pay longs. This happens when the perpetual futures price trades below the spot price (bearish sentiment). If you are long during negative funding, you receive payments every 8 hours instead of paying them. Negative funding rates often signal extreme bearishness — contrarian traders watch for deeply negative funding as a potential long opportunity.
