What is the payment amount determined by the bank?

Actually, more than that:

1. The amount of regular payments.
2. The number of regular payments (excluding the last payment, if irregular).
3. At least one of the following (and preferably both, to double-check):
a. The amount of the last payment.
b. The total amount of all payments.
4. Any information that the lender provided about the daily interest rate.
