Declined purchase of $29.99 with a $30.98 Apple balance.
Why was my purchase of $29.99 declined for insufficient funds when the balance on my account was $30.98?
iPhone XR, iOS 15

Probably because $30.98 its not enough to cover the item plus any sales taxes applied in your region. Remember, iTunes prices are before taxes in many countries. So you need to consider your local sales tax for the final price.
