# Fees

Mozaic charges a performance fee on Theseus's performance which is structured as follows:

* **Fee rate:** 10% on positive vault performance.
* **Calculation basis**: The fee is applied when the Theseus Vault's net asset value (NAV) appreciates. No fees are applied when NAV decreases.
* **Fee claim:** Fees are claimed periodically and are credited to the Mozaic DAO's earnings wallet at this address: [<mark style="color:yellow;">https://arbiscan.io/address/0xa766bab0854469bf9449451cf827190c3408eeb7</mark>](https://arbiscan.io/address/0xa766bab0854469bf9449451cf827190c3408eeb7)
* **Performance period:** Fees are calculated and accrued each time a deposit or withdrawal affects the Theseus Vault's total value locked (TVL). This ensures fair treatment for all users, regardless of when they enter or exit the vault.
