Just an additional thought on your comment about the Finance Charge box and Amount Financed box not equaling the Total of Payments, even though the payment schedule payments do equal the Total of Payments....
Typically, the Finance Charge and Amount Financed will equal the Total of Payments, but not always. For example, if the loan has credit insurance premiums or debt cancellation payments based on a monthly outstanding balance amount, (as opposed to single-premium insurance where the premium is paid all at closing), the payment schedule should still equal the Total of Payments, but will not equal the total of Finance Charge and Amount Financed.
