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.
Frequently asked questions
What does the schedule show?
The first 12 months of principal, interest, and remaining balance, followed by the monthly payment and total interest over the full term. A $300,000 loan at 6.5% for 30 years pays $1,896.20 a month and $382,633.47 in total interest.
Why is so much of each early payment interest?
Interest is charged on the remaining balance, which is highest at the start. As the balance falls, the interest share shrinks and more of the same fixed payment goes to principal.
Does it include taxes, insurance, or PMI?
No. It covers principal and interest only. Add property tax, homeowners insurance, and any PMI separately to get a full housing payment.
