FAQ

What is an amortization schedule?
A breakdown of every payment over the life of the loan, showing how much of each payment goes to interest versus principal and how the balance falls to zero.
Why is so much of my first payment interest?
Interest is charged on the outstanding balance, which is highest at the start. Early payments are mostly interest, and the principal portion grows each month as the balance drops.
How is the first-month interest calculated?
It is the loan amount times the monthly rate (annual rate ÷ 12 ÷ 100). The rest of the payment goes to principal.
