How to Use the Amortization Calculator
Enter the loan amount, interest rate, and term, and the calculator generates the complete month-by-month schedule showing exactly how much of each payment covers interest versus principal, and what balance remains after each one — expand to see the full schedule or just the first year, depending on what you need.
This tool is built for anyone who wants to see the actual mechanics behind their loan, not just the summary numbers.
Reading the monthly breakdown
Each row shows a single month's payment split into interest and principal, plus the balance remaining afterward — as covered in the amortization guide, expect the interest column to start high and shrink steadily while the principal column does the opposite.
Using it to plan extra payments
Comparing the schedule at different terms or amounts helps quantify exactly how much interest a shorter term or extra principal payment would save — as covered in the slow-balance guide, this is especially useful for seeing just how much extra payments early in the term help versus the same extra amount made later.
