💸 What is Loan Amortization? A Complete Guide
If you've ever taken out a major loan, such as a mortgage or an auto loan, you've encountered the concept of loan amortization. In simple terms, amortization is the process of paying off a debt over time in regular installments. Each payment consists of both principal and interest. What makes it interesting is that the proportion of principal and interest changes with every payment. Our Loan Amortization Calculator is designed to demystify this process, showing you exactly where your money goes.
The Loan Amortization Schedule: Your Financial Roadmap
The core of amortization is the loan amortization schedule. This is a detailed table that breaks down each payment of your loan over its entire term. A typical schedule, like the one our calculator generates, will show:
- Payment Number: The sequence of your payments.
- Payment Amount: The fixed amount you pay each period.
- Principal Paid: The portion of your payment that reduces your loan balance.
- Interest Paid: The portion of your payment that goes to the lender as profit.
- Remaining Balance: Your outstanding loan amount after the payment.
At the beginning of a loan, a larger portion of your payment goes towards interest. As you continue to make payments, more and more of your money goes towards paying down the principal. This is clearly visualized in our loan amortization table and charts.
The Loan Amortization Formula
The calculation for the fixed monthly payment (M) is based on the following loan amortization formula:
Where:
- P = The principal loan amount
- i = The monthly interest rate (your annual rate divided by 12)
- n = The total number of payments (loan term in years × 12)
Our calculator handles this complex formula instantly. By checking the "Show Calculation Steps" box, you can see exactly how your monthly payment is derived.
