Amortization Schedule Builder
Build a loan amortization schedule.
Where each payment goes
Every fixed loan payment splits between interest and principal, and the mix shifts over time: early payments are mostly interest, later ones mostly principal. This builds the full month-by-month schedule from your amount, rate, and term.
Seeing the schedule makes the case for extra payments concrete: an additional amount each month goes entirely to principal, erasing the interest that row would have charged for the rest of the term.
A planning estimate
Real statements may differ by rounding and fees, so use this to plan rather than reconcile. The loan figures you enter never leave your device.
