# Fees

> What Monofin charges — itemized on every ticket, in dollars, before you confirm.

No hidden fees. No fine print. Every cost on Monofin is itemized on the order ticket **before** you confirm, in dollars.

## Trading fees

| Market type | Venue fee | Monofin builder fee |
| - | - | - |
| **Perpetuals** | Set by the underlying venue, varies by market | **0.05%** of position size per fill |
| **Event markets** | Set by the venue, varies by market | Small percentage per fill, shown on the ticket |
| **Real-world assets** | Set by the deployer/venue | Same structure as perps |

The builder fee is how Monofin makes money: it keeps the routing, the apps, and the social layer running. It's competitive with other frontends on the same venues, and it's always its own line on your ticket — never blended, never buried.

### A worked example

You open a **\$1,000 BTC perp position**:

* Monofin builder fee: $1,000 × 0.05% = **$0.50\*\*
* Venue fee: shown on the ticket at the venue's current rate
* **Total cost: exact dollar amounts, itemized, before you confirm.**

Closing the position is another fill — same structure. On event markets, the fee is calculated on the shares you buy or sell and shown the same way.

## Funding is not a fee

On perps, **funding payments** move between longs and shorts to keep prices anchored to the underlying market. Depending on the rate, you pay funding or receive it. It's a market mechanism, not Monofin revenue. See [Leverage, funding, and liquidations](/trading/leverage-funding-liquidations.md).

## No fees on

* **Deposits and withdrawals** — Monofin charges nothing to move money in or out (network gas and on-ramp provider fees may apply, shown before you confirm)
* **Holding a balance** — no account fees, no inactivity fees
* **Earn deposits** — vaults carry their own curator fee structure, disclosed on each vault's page
