Complete Guide to Loan Amortization and Payment Strategies
Understanding Amortization
Loan amortization is the process of gradually paying off a debt through regular payments over time. Each payment covers both principal (the amount borrowed) and interest, with the proportion changing throughout the loan term.
Our calculator shows you exactly how each payment is allocated, helping you understand the true cost of borrowing and identify opportunities to save money.
Key Amortization Concepts
- • Principal: The original loan amount
- • Interest: The cost of borrowing money
- • Payment: Fixed amount paid each period
- • Term: Length of time to repay the loan
- • Balance: Remaining amount owed
