Download the spreadsheet for free here - http://readtome.net/2020/12/30/amortization-spreadsheet-download/ This tutorial shows you how to use the mortgage calculator spreadsheet to understand your home loan and how you can explore and evaluate different loan choices. For example, is a 30 yr loan better for you vs a 15 yr? How much impact does making additional payments make? What are the tax consequences? The spreadsheet can be used in Microsoft Excel or can be imported into Google Sheets which is absolutely free! Would love your feedback on how we can improve this.
