Is the versionning of the secret in large quantities in Azure Key Vault will be extra paid?

Hello,
I would like to store one secret in KeyVault, which value will be changed every day, so it will add extra version for secret each day.
I am curious, whether it will be extra paid and what consequences it will be have?
From other discussion, I read that one consequences will be some performance problems with backup the secret, but I don't plan to do it, so Am i safe?

Kind regards
