Publisher's Synopsis
The immense power of compound interest is such that adding a small amount of extra principal to each of your mortgage payments will result in thousands (or tens of thousands) in interest savings over the life of your loan. Using only high-school mathematics, Tim Hill provides clear and readable lessons that you can use to understand and pay down your mortgage by using Microsoft Excel (or any spreadsheet software). This entirely practical guide teaches you how to use worksheet functions, array formulas, data tables, and other spreadsheet features to manage your business and personal finances. You'll also learn the auxiliary skills needed to create and maintain financial spreadsheets: rounding numbers, date and time arithmetic, summing and counting values, and more. Plenty of examples show you how to use these tools for any type of debt or savings: mortgages, student loans, leases, credit-card debt, car payments, medical expenses, annuities, and retirement funds. You can download the sample workbooks to follow along with the author's examples and calculations.
