# What is Funding Rate?

The Funding Rate is a recurring payment given to traders going long or short, determined by the gap between the perpetual contract's market price ([Last price](/trading/last-price-mark-price-and-oracles.md)) and the spot price ([Mark Price](/trading/last-price-mark-price-and-oracles.md)). When the market trends upwards, the Funding Rate is positive, and long traders pay a fee to those going short. On the flip side, in a downward market, the Funding Rate is negative, and short traders pay the fee to those going long.

NEXDEX doesn’t levy any fees for these fund transfers between traders. The funding fees on NEXDEX are assessed every hour. Traders will only be part of this fee swap if they have open trades at the designated fee times. Traders who do not have an open position will not pay or receive any funding.

## Calculation

`Funding Payment = Position Size * Hourly Funding Rate (HFR)`

`Position Size = Position Quantity * MarkPrice`

`HFR = Cap((TWAP((SyntheticVWAPExecutionPrice - MarkPrice)/MarkPrice) + DailyInterestRate) * 1/24)`

`SyntheticVWAPExecutionPrice = (Price_A*Volume_A +Price_B*Volume_B +Price_C*Volume_C)/(Volume_A + Volume_B + Volume_C)`

* `A` is the market buy batch execution
* `B` is the market sell batch execution
* `C` is the limit matching batch execution

Funding payments are applied to the whole market by modifying the `CumulativeFunding` value. Each position stores the current `CumulativeFunding` as `CumulativeFundingEntry`. Subsequent funding payments are only applied upon position changes and can be calculated as:

**FundingPayment**

* For Longs: `FundingPayment ← PositionQuantity * (CumulativeFunding - CumulativeFundingEntry)`
* For Shorts: `FundingPayment ← PositionQuantity * (CumulativeFundingEntry - CumulativeFunding)`
* `Margin' ← Margin + FundingPayment`
* `CumulativeFundingEntry' ← CumulativeFunding`
