Understand Amortization Projections
Amortization spreads out loan balances over periodic installations, showing exactly how much of each payment covers principal vs. interest.
How an amortization schedule works
An amortization schedule shows how each regular loan payment is split between interest and principal. Interest is generally calculated from the outstanding balance and periodic rate; the remainder of the payment reduces principal.
Compare payment amounts and total interest across different loan terms. Actual lender schedules may differ due to fees, variable rates, payment timing, rounding, or extra payments.
