# Vault fees ### Management fees 🤖 Lobster, for the proper functioning of the protocol, must take fees on the management of funds. These fees are already taken into account, and already perceived in all our track records displayed in order to be as transparent as possible about user earnings. No need to remove them a second time during your calculations. There is a 3% annual charge on TVL, deducted in small fractions every 4 hours. These are the only charges levied over the lifetime of your investment. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
