What is a funding rate in crypto?

Funding rate is a periodic fee paid between long and short traders in perpetual futures markets. It keeps the futures price close to the spot price.

How often is funding fee charged?

Most exchanges charge funding every 8 hours (3 times per day). Binance and Bybit use 8-hour intervals.

When do I pay vs receive funding?

If funding rate is positive, longs pay shorts. If negative, shorts pay longs. You receive funding when you are on the profitable side.

What is a typical funding rate?

Normal funding rates are 0.01% per 8 hours (0.03%/day). During bull runs, rates can spike to 0.1% or higher, costing significantly more.

Crypto Funding Rates: What They Are & How to Trade Around Them

Funding rates are a hidden cost that many traders overlook — until they see their profits eroding. In perpetual futures markets, funding is paid every 8 hours to balance the market between longs and shorts. When most traders are long, the rate goes positive and longs pay shorts.

At 0.05% per 8 hours (3× per day), you're paying 0.15% daily on your position. On a $10,000 position that's $15/day or $450/month just to hold. This can completely negate profits on a slow-moving trade.

Advanced traders watch funding rates as a sentiment indicator. Extremely high positive rates (0.1%+) signal overleveraged longs — historically a contrarian bearish signal. Use this tool to calculate the real cost of holding any perpetual futures position overnight.

About the Crypto Funding Fee Calculator

A crypto funding fee calculator works out how much you'll pay or earn from funding rate payments on a perpetual futures position, based on your position size, the funding rate, and how long you hold. Funding fees get charged (or paid to you) every few hours on perpetual contracts, and this tool tallies up what that actually costs over time.

Why This Tool Exists

Funding fees are easy to overlook when focusing on price movement alone, but they can quietly eat into profits on positions held for days or weeks. This tool exists to make that ongoing cost visible before you commit to holding a leveraged position long term.

How to Use It

Step 1. Enter your total position size.
Step 2. Enter the funding rate (usually shown per 8-hour interval on most exchanges).
Step 3. Enter how many funding intervals or days you plan to hold the position.
Step 4. Click Calculate to see your total funding cost or income.

How It Works

Funding fee is calculated as Position Size × Funding Rate, applied at each funding interval — typically every 8 hours. If you're holding a $10,000 position with a funding rate of 0.01% per interval, that's a $1 charge every 8 hours, or roughly $3 a day, which adds up to $90 over a month of holding — a cost that's easy to forget about when focused purely on price direction.

Frequently Asked Questions

What is a funding fee in crypto trading?

It's a periodic payment exchanged between long and short position holders on perpetual futures contracts, designed to keep the contract price aligned with the spot price.

How often are funding fees charged?

Most major exchanges charge funding every 8 hours, though this can vary by platform and by the specific trading pair.

Do I always pay funding fees?

Not always — when funding rate is positive, longs pay shorts; when it's negative, shorts pay longs, so depending on your position direction, you might actually receive funding.

Does funding rate depend on leverage?

Funding fee is based on your total position size (including leverage), not just your margin, so higher leverage means a larger absolute funding cost.

Can funding fees make a profitable trade unprofitable?

Yes, especially on long-held positions during periods of high funding rates — it's a real cost that should be factored into your overall trade planning.
