Gregory Jul 09, 2026

Ever found yourself wondering, "What is an interest only loan called?" You're not alone. This type of loan is often referred to by several names, each highlighting a unique aspect of its structure and repayment terms. Let's delve into the world of interest only loans, exploring their various aliases and the key features that set them apart.

Interest only loans, also known as interest-only mortgages or interest-only home loans, are a type of loan where the borrower only pays the interest on the principal amount borrowed, rather than making payments towards the principal itself. This type of loan offers several advantages, including lower monthly payments and the flexibility to pay off the principal at a later stage. But what are these loans called, and how do they differ from other loan types?

1. Interest-Only Mortgages: This is perhaps the most common term used to describe these loans. It emphasizes the fact that these loans are primarily used for purchasing real estate, and the borrower only pays the interest on the mortgage amount.

Interest-Only Mortgages vs. Conventional Mortgages

Interest-only mortgages differ from conventional mortgages in their repayment structure. While conventional mortgages require borrowers to pay both interest and a portion of the principal each month, interest-only mortgages only require the interest payment. This results in lower monthly payments, making these loans an attractive option for borrowers looking to manage their cash flow more effectively.

However, it's essential to note that while the monthly payments are lower, the total amount paid over the life of the loan can be higher due to the extended repayment period. Additionally, borrowers will need to pay off the principal amount in full at the end of the loan term, which can be a significant financial burden if not planned for appropriately.

Another type of loan that shares some similarities with interest-only mortgages is the balloon mortgage. Both loan types require the borrower to make interest-only payments for a specified period. However, balloon mortgages differ in that they have a larger, lump-sum payment due at the end of the loan term, often referred to as a "balloon payment." This payment can be quite substantial, as it represents the remaining principal amount of the loan.

Interest-only mortgages, on the other hand, do not typically have a balloon payment. Instead, the borrower is responsible for paying off the principal amount in full at the end of the loan term through a separate financial instrument, such as a savings account or an investment vehicle.

1. Interest-Only Student Loans: In the education sector, interest-only student loans allow students to defer payments on the principal amount of their loan while they are in school. This can help students manage their finances more effectively during their studies, as they only need to pay the interest on their loan each month. However, it's essential to note that the total amount owed will increase over time due to the accumulation of interest.

Interest-Only Student Loans vs. Income-Driven Repayment Plans

Interest-only student loans differ from income-driven repayment plans, such as Income-Based Repayment (IBR) and Pay As You Earn (PAYE). While both plans allow borrowers to cap their monthly student loan payments based on their income, income-driven repayment plans also forgive any remaining loan balance after a certain number of years of on-time payments. Interest-only student loans, on the other hand, do not offer loan forgiveness and can result in a higher total amount owed if not managed carefully.

2. Interest-Only Business Loans: In the business sector, interest-only business loans allow business owners to make lower monthly payments by only paying the interest on their loan. This can provide businesses with the capital they need to grow and expand, while also helping them manage their cash flow more effectively. However, it's essential to note that these loans can be riskier for lenders, as the borrower is not building any equity in the loan through principal payments.

Interest-only business loans can be structured in various ways, with some lenders offering loans with a fixed interest rate and term, while others offer loans with a variable interest rate and a balloon payment at the end of the loan term.

In the world of finance, interest only loans go by many names, each highlighting a unique aspect of their structure and repayment terms. Whether you're a homeowner, a student, or a business owner, understanding the various names and features of interest only loans can help you make more informed financial decisions. By exploring the different types of interest only loans available and weighing the pros and cons of each, you can find the loan that best fits your financial needs and goals.
