# APR

The APR is the annual percentage rate of your Vault. This percentage can be increased by exchanging your $DMS.

As soon as the Vault is minted it starts with a **default basic APR of 5%**.

During the minting phase, you can increase your Vault’s APR by **exchanging 8** $DMS **for every extra 1% APR** up to a maximum of 440 $DMS for a 60% APR.

You can boost your Vault only upon minting, not after that. 

> E.g., if you have 12 $DMS, you can:
>
> * mint a VaultNFT with 4 $DMS
> * boost your APR by +1% APR with extra 8 $DMS
>
> If you have 36 $DMS, you can mint a Vault with +9% APR (4 cards for minting + 32 cards for boosting APR).
