Starting balance
The amount you owe before the first payment in the schedule.
See your full payment schedule showing how each payment splits between principal and interest.
Amortization simply means paying a debt down bit by bit. This schedule shows how each payment is split between paying back borrowed money and paying interest, and how the balance changes over time.
Early payments usually go mostly to interest. Later payments reduce the balance faster. Try an extra monthly payment and compare the payoff date and interest total; confirm with your servicer that extra money goes to principal and check any prepayment restrictions.
The amount you owe before the first payment in the schedule.
The yearly cost of borrowing, converted into a monthly charge on the remaining balance.
The original repayment period in years. More years usually means a smaller payment but more interest.
Additional money sent toward the balance, beyond the scheduled payment.
Money still owed after a payment; it is not the same as future interest.
The accumulated borrowing cost and when the loan reaches zero under these assumptions.

Monthly principal and interest use P × r / (1 − (1 + r)−n), where P is the loan amount, r is the monthly note rate and n is the number of payments. At zero interest, use P / n. Add property taxes, homeowners insurance and applicable mortgage insurance to estimate the full payment. Use parcel-specific taxes and an insurance quote when comparing homes.
APR includes applicable finance charges; use the note rate, not APR, for amortization. Compare Loan Estimates with the CFPB guide.
