### Introduction

What the calculator does.

This calculator will calculate the present value of an annuity starting with either a future lump sum, or with a future payment amount.

Plus, the calculator will calculate present value for either an ordinary annuity, or an annuity due, and display a year-by-year chart so you can see the how the balance will decline to zero over the course of the entered number of years.

If you are not sure what *present value* is, or you wish to calculate present value for a lump sum only, please visit the Present Value of Lump Sum Calculator.

Or, if you would like to calculate the future value of an annuity, please visit the Future Value Annuity Calculator -- which also includes answers to *What is Annuity?* and *Annuity Due Vs. Ordinary Annuity?* in case you're not familiar with the terms used in this calculator.

With that I invite you to use the Present Value Annuity Calculator for calculating present value of annuity starting with either a future sum or with a future payment amount.
