Hi Phanip,

By default setup and fields you cannot implement this use case but instead, you can implement a new component or custom flow that can fetch the total from the child records and then show the total amount component on the account record page that can show the total value.

I hope this helps and in case if this comes in handy can you please choose this as best answer so that it can be used by others in the future.
