Funding Fee Calculator

Free Tool

by CryptoFXRadar

Funding fees are a hidden cost (or income) in crypto perpetual futures. This tool estimates how much you may pay or receive based on your position size, funding rate, and holding time. Educational estimate only.

How this calculator works

Funding fees are periodic payments exchanged between long and short traders to keep perpetual futures close to spot price.

• Positive funding: longs usually pay shorts
• Negative funding: shorts usually pay longs

Formula (estimated)

Funding Fee = Position Size x Funding Rate x Number of Funding Intervals

This is a simplified estimate. Real funding depends on the exchange, mark price, and live funding rules.
