What This Calculator Does

A funding fee calculator estimates how much you will pay or receive in periodic funding on perpetual futures. Inputting position size, funding rate, and number of periods returns the total funding cost (or credit). This is essential for swing traders who hold positions across multiple funding intervals because cumulative funding can materially change net PnL.

How the Calculation Works

Funding is typically position notional × funding rate per period. The calculator multiplies your position size by the rate and the number of periods. If you hold a $20,000 position through six 0.01% funding periods, total funding is about $12. Increasing position size or rate raises the cost linearly. By previewing this, you can decide whether to hold, reduce size, or close before expensive funding windows.

Example Calculation

Consider a $50,000 ETH perpetual position with a 0.015% funding rate every 8 hours. Holding through 9 periods (three days) costs roughly $67.50. If the trade’s expected edge is small, those fees could erase gains. The calculator makes this tradeoff explicit so you can weigh expected price move versus funding drag before committing to a multi‑day hold.

Trading Tips

Track funding alongside PnL; a flat price with negative funding still loses money. Reduce size or close before unusually high funding windows. When funding is positive for your side, don’t let the payment lure you into weak trades—price movement usually dominates. Combine funding estimates with stop placement and target setting for a full view of holding costs.

Frequently Asked Questions

What is a funding period?

Most exchanges settle funding every 8 hours, but it can vary.

Can funding be negative?

Yes. Depending on market skew, you might pay or receive funding.

Does leverage matter?

Funding is charged on notional size; higher leverage increases notional and funding cost.
