5 1 Arm vs 15 Year Fixed Calculator

When shopping for a mortgage, you'll encounter two common loan options: the 5/1 Adjustable Rate Mortgage (ARM) and the 15-year fixed-rate mortgage. Both have their advantages and disadvantages, and understanding the differences is crucial for making an informed decision. This guide explains the key differences between these two mortgage types and provides a calculator to help you compare them.

Introduction

A 5/1 ARM is an adjustable-rate mortgage where the interest rate adjusts after the first five years of the loan term. The initial interest rate is fixed for the first five years, and then it adjusts annually based on market conditions. A 15-year fixed-rate mortgage, on the other hand, has a fixed interest rate for the entire 15-year term.

Key Differences

Interest Rate: 5/1 ARM has a fixed rate for the first five years, then adjusts annually. 15-year fixed has a fixed rate for the entire term.
Term: Both have a 15-year term, but the ARM's rate adjusts after the first five years.
Payments: Initial payments on a 5/1 ARM are lower than a 15-year fixed, but they may increase after the first five years.

Understanding these differences is essential for making the right choice. The calculator on this page helps you compare the two options based on your specific financial situation.
