Amortization Definition | Business Lending Glossary
Plain-language definition of loan amortization for small business owners. Understand how amortization schedules work and what they mean for your payments.
Definition
The process of paying off a loan through scheduled, equal payments that cover both principal and interest over the loan's term.
Explanation
When a loan is amortized, each payment is split between interest and principal reduction. In the early periods, a larger share of each payment goes toward interest. As the principal balance decreases over time, more of each payment reduces the actual debt. This structure is used for term loans, SBA loans, equipment financing, and commercial real estate loans. A fully amortized loan is paid off completely at the end of its scheduled term with no balloon payment required.
Example
A $100,000 business term loan at 8% APR amortized over 5 years has a monthly payment of approximately $2,028. In month one, roughly $667 goes to interest and $1,361 to principal. By month 60, nearly the entire payment goes to principal.
Why It Matters
Understanding amortization helps you evaluate the true cost of a loan. An amortizing loan with a longer term has lower monthly payments but higher total interest cost. Comparing amortization schedules lets you see exactly how much you pay in interest over the life of a loan.
Frequently asked questions
What is the difference between amortizing and non-amortizing loans?
An amortizing loan has fixed payments that reduce the principal balance over time. A non-amortizing loan, sometimes called an interest-only loan, only requires interest payments during the term, with the full principal due at maturity as a balloon payment.
How does amortization affect my monthly payment?
A longer amortization period results in a lower monthly payment but more total interest paid. A shorter term means higher monthly payments but less overall interest cost. Use an amortization calculator to compare options.
