About This Tool
Demystifying Your Loan
Taking out a loan is a major commitment. Whether it's a 30-year mortgage or a 60-month auto loan, understanding how your payments are distributed is key to saving money.
This Amortization Schedule breaks down every single payment for the life of your loan.
Principal vs. Interest: The Shift
In the early years of a long-term loan, the majority of your payment goes toward Interest. This means your loan balance drops very slowly at first.
- Early Payments: Mostly Bank Profit (Interest).
- Later Payments: Mostly Debt Reduction (Principal).
By paying just a little extra principal early on, you can skip the "interest-heavy" front end of the curve and save thousands.

How this tool works
Methodology reviewed 2026-07-11This tool calculates a level monthly payment from principal, annual percentage rate, and number of monthly payments. For each schedule row, interest equals the opening balance multiplied by the monthly rate; principal equals payment minus interest; and the remaining balance is reduced by that principal amount. A zero-interest loan is handled by dividing principal evenly across the term instead of using the exponential formula.
Worked example
On a fixed $10,000 loan at 6% for 24 months, early payments contain more interest because they begin with a larger unpaid balance, while later payments direct more of the same scheduled amount toward principal.
How to interpret it: The schedule explains allocation, not every contractual charge. Compare it with the lender disclosure because fees, daily interest conventions, payment dates, extra payments, and rounding can make an actual statement differ.
Assumptions
- The loan uses a fixed annual rate converted to a monthly rate.
- The scheduled payment is made once per month and on time.
- No fees, skipped payments, late charges, or additional principal are included unless the tool explicitly accepts them.
Limitations
- Variable-rate, interest-only, balloon, and irregular-payment loans require different models.
- Individual rows can differ by a few cents because real servicers apply contract-specific rounding.

Frequently Asked Questions
What does 'Amortization' actually mean?
It comes from the Latin 'admortire' (to kill). It literally means 'killing off' the debt through regular payments. In finance, it refers to the schedule of spreading out the loan cost over time.
Why is my first payment almost all interest?
Interest is calculated on your remaining balance. At the start, your balance is huge, so the interest charge is huge. As you pay it down, the interest portion shrinks, and more money goes to principal.
