How the amortization schedule calculator works
Each month interest equals balance × monthly rate. The rest of the fixed payment reduces principal. Early payments are mostly interest; later payments are mostly principal.
Example
Using the default inputs (Loan amount: $300,000; Interest rate: 6.5%; Term (years): 30), the calculator returns monthly payment of $1,896. Change any field above to see your own result and charts update instantly.

Frequently asked questions
Why is so much of my early payment interest?
Interest accrues on the outstanding balance, which is largest at the start. As principal falls, more of each payment goes to principal.
Does this work for auto and personal loans?
Yes. Any fixed-rate, fully amortizing loan follows the same math.
