Why Use a 10-, 15-, 20-, or 30-Year Mortgage Calculator to Compare Mortgages?

A regular mortgage calculator is helpful in determining the cost of one mortgage. But, if you are considering more than one mortgage, they are not necessarily efficient. Understanding the significant savings on interest from a shorter loan is easier when you use a 15-year vs 30-year mortgage calculator, for example.

Suppose you are considering three mortgages: a 15-year, 20-year, and 30-year mortgage. You can use a 15-year mortgage calculator, 20-year mortgage calculator, and a 30-year mortgage calculator separately to determine the one that fits your financial goals.

Or, you can choose compare mortgage calculators, like a 15-year vs. 30-year mortgage calculator, that will compare two or more mortgage terms side-by-side. Some mortgage rate comparison calculators will compare mortgages for 1- to 40-year terms, so you can compare the loan lengths you need.

The best thing about compare mortgage calculators, like a 20-year vs. 10-year mortgage calculator, is that the results are simple to compare. The calculators reviewed in this guide provide you with a side-by-side comparison of your monthly payment, and other information, for each loan.

You can also use some mortgage rate comparison calculators as mortgage early payment calculators if you want to pay additional money each month to pay off your loan faster. 

This mortgage calculators comparison guide will explain the benefits of each calculator and how they can help you determine the best loan with one calculator.
