How funding is calculated

Funding is charged on the position size, not on your margin, once per settlement period.

  1. Rate × size

    On NVDA a long currently pays 0.0023% of the position every 1h. On $1,000 that is the per-period charge.

    per period = size × rate

  2. × whole periods held

    Only completed settlement periods are counted. Held for a week, $1,000 of NVDA pays $3.84.

    funding = size × rate × periods

  3. Per year, simple

    At today's rate, NVDA funding adds up to 20% of the position over a year, not compounded. Rates move, so treat it as a snapshot.

    yearly = rate × periods per year

Funding, answered

How often is funding charged on BRVX?

Every hour on most markets, every 3 hours on XYZ100. The calculator uses each market's own period.

Is funding charged on margin or on position size?

On position size. $100 of margin at 10x is a $1,000 position, and funding is charged on the $1,000.

Do longs and shorts pay the same rate?

Not always. The rate depends on the market and the side; on some markets, such as BTC, the long and short rates differ. Pick the side in the calculator to use the right one.

Does funding change?

Yes. The calculator shows the rate from the BRVX feed at the moment you open the page; the rate in the app when you trade is the one that applies.

Where do I see the total cost of a trade?

The cost calculator on the fees page adds the opening and closing fee to funding for the same hold time.

Leverage works both ways: a small move against you can lose you the whole margin.
