# Fees

NFTX keeps its fee model simple and honest: **getting in and out is free, and fees live only where value is actually priced** — listing an item above floor, and swapping. There's no deposit fee and no redemption fee.

## Feeless entry and exit

[Minting](/core-concepts/minting-and-redeeming.md) an NFT into a floor token and [redeeming](/core-concepts/minting-and-redeeming.md) a floor token back into an NFT are both **feeless** — you pay only gas. This is deliberate: NFTX wants the fungible state to be frictionless to enter and leave, so liquidity isn't taxed at the door.

## Listing fees (tax)

When you create a [Liquid Listing](/how-it-works/liquid-listings.md) above floor, you prepay a **listing fee** — often called tax — in the collection's floor token. It's the price of asking more than floor, and it does two jobs: it funds the sale and it discourages overpricing.

The fee scales with the **square of the floor multiple** and **linearly with duration**, normalised to a 7-day reference, with a softening **kink at 2.00x** so high-value grails stay viable. A 7-day listing works out to:

| Floor multiple | Fee (7-day listing) |
| -------------- | ------------------- |
| 1.50x          | 0.0225 FLOOR        |
| 2.00x (kink)   | 0.04 FLOOR          |
| 3.00x          | 0.0625 FLOOR        |
| 4.00x          | 0.09 FLOOR          |
| 10.00x         | 0.36 FLOOR          |

The tax is **prepaid** when the listing is created and **refunded pro-rata** if you cancel or shorten it, so you only ever pay for the price and time you actually use. The full formula and the reasoning behind the kink are in the [Tax Calculator](/contracts/tax-calculator.md).

## Swap fees

The other place NFTX charges is **swaps**. Every collection's floor token trades against ETH in a Uniswap V4 pool, and a swap fee is taken on those trades. The fee is collected through the [NFTX V4 Hook](/contracts/nftx-v4-hook.md), which is the single integration point for pool fees — including per-collection fee levels and fee exemptions.

## Where the fees go: real yield for liquidity providers

Listing and swap fees don't disappear into a treasury black box — they're routed back to the people providing liquidity. NFTX uses Uniswap V4's `donate()` method to send this revenue **directly into the collection's pool**, where liquidity providers (LPs) claim it the same way they claim ordinary swap fees. NFTX calls these **exogenous fees**: revenue that originates outside the pool's own trading but is paid out through it.

The payoff is **real yield** for LPs beyond raw swap volume, which helps offset **impermanent loss** — the opportunity cost an LP takes on when the prices of the two pooled assets move apart. More fee income flowing to LPs makes providing liquidity to NFTX pools more sustainable.

In short: **feeless in and out, fees on listings and swaps, and those fees flow back to liquidity providers** through the pool itself.
