Funding Rate Calculator
Funding cost = position value × funding rate × number of 8-hour periods. A $10,000 position at the typical 0.01% per 8h pays about $1/day — but at 0.1% in a hot market that becomes $10/day, or ~3.65% of the position per year.

Frequently asked questions
What is a funding rate?
A periodic payment between longs and shorts (usually every 8 hours) that keeps a perpetual contract price anchored to spot. Positive rate: longs pay shorts. Negative: shorts pay longs.
Is funding charged on margin or position value?
On full position value. At 20x leverage a 0.01% funding rate per 8h equals 0.2% of your margin per period — leverage multiplies funding exactly as it multiplies price moves.
How do I avoid heavy funding costs?
Check the current and predicted rate before entry, prefer shorter holding periods when rates spike, and compare exchanges — the same pair can have very different rates across venues.
