Annunity Calculator for Excel

This Annuity Calculator Spreadsheet contains two worksheets. The first worksheet shows a yearly Cash Flow table and a graph of the Balance. It solves for the annuity payment amount. In the second worksheet, you can solve for the annuity payment, the initial principal, or the number of years to pay out. Both worksheets allow you to specify an annual inflation rate which will cause the withdrawal or annuity payment to increase over time.
