How To Calculate A Balloon Payment In Excel

On This Page, You can easily know about How To Calculate A Balloon Payment In Excel.

While most loans are fully paid off throughout the life of the loan, some loans are set up such that an additional payment is due at the end. These payments are known as balloon payments and can often be found within fixed-rate or adjustable-rate mortgages. The use of a balloon payment can allow for lower monthly payments when compared to a fully-amortizing loan (a loan that is paid off during its life), but can also result in a truly massive payment at the end of a loan. In many cases, the balloon payment must itself be refinanced and paid off as an additional loan. Calculating a balloon payment or the payments that will be made on a loan with a certain balloon payment amount is simple using Microsoft Excel.

An Application of the Balloon Loan

The balloon loan can be used as an important tool in financial management. Consider an example of a small business that plans to develop a new product. The development requires an investment and will not yield cash flows in the initial years. Using a balloon loan, in such a case, will reduce the financial burden of the business during the development phase since their initial payments are lower.

As the business moves out of the development phase and grows, it can generate sufficient cash flows to service the balloon payment at the end of the loan. It also helps in financial planning, as payments can be modified to meet the current financial conditions of the business.
