About the Present Value of Annuity Calculator
The Present Value of Annuity Calculator is a comprehensive online tool designed to help you calculate the present value of future regular payments. Whether you're evaluating an investment, planning for retirement, or analyzing a loan, this free calculator provides accurate results instantly.
Understanding Present Value of Annuity
The present value of an annuity is the current worth of a series of future payments, given a specified discount rate. This concept is fundamental in finance because a dollar received today is worth more than a dollar received in the future due to its potential earning capacity.
PV = PMT x [(1 - (1 + r)-n) / r]
Ordinary Annuity vs. Annuity Due
Ordinary Annuity: Payments are made at the end of each period. Most loans and mortgages work this way. The formula above calculates ordinary annuity.
Annuity Due: Payments are made at the beginning of each period. Rent payments and insurance premiums typically work this way. The present value of an annuity due equals the ordinary annuity PV multiplied by (1 + r).

Frequently Asked Questions
Present value (PV) tells you what a future sum of money is worth today, while future value (FV) tells you what today's money will be worth in the future. PV discounts future cash flows back to today; FV compounds today's money forward.
A higher discount rate means money in the future is worth less today because you're assuming you could earn a higher return on money you have now. If you could earn 10% per year, $100 received next year is only worth about $91 today, but at 5%, it's worth about $95.
Use Ordinary Annuity when payments are made at the end of each period (most loans, mortgages, bonds). Use Annuity Due when payments are made at the beginning of each period (rent, insurance premiums, lease payments).
If you want to receive $3,000 per month for 25 years in retirement, this calculator tells you how much you need saved today (assuming a certain rate of return) to fund those payments. This helps set realistic savings goals.
The discount rate depends on your situation. Common choices include: current interest rates for similar investments, your expected rate of return, inflation rate for real value calculations, or your personal required rate of return. For conservative estimates, use a lower rate.
