PVIFA - is an acronym for present value interest factor of an ordinary annuity in amount of \$1 that makes n payments and pays i% interest. The PVIFA calculation using paper and pencil are time consuming and error prone thus one would desire to find this amount using Excel.

There are a large number of financial functions in tadXL including tadPVIFA that find this interest amount.

In spring of 2012, tadXL was released to the software market that offered a large collection of financial functions for Excel 2007, 2010 and 2013. Amongst these financial functions, there was tadPVIFA function to find the present value annuity factor of \$1 periodic payments that earn i% interest rate for n number of periods. tadPVIFA function offered features for additional options to include compounding frequencies of interest, to define the length of the payment periods and to use various discounting conventions such as mid-year discounting. As stated earlier Excel had no such financial function up till Excel 2013 so it be surprising the least if Microsoft were to introduce new set of financial functions in the upcoming Excel 2015 or 2016. If they were to do so then more than likely such new financial functions in upcoming Excel would be copies of the financial functions that are found in tadXL add-in and have been available since 2012.
