What is Present Value?
Present value (PV) is what a future sum of money is worth today, after accounting for the interest it could earn in the meantime. A dollar you will receive in 20 years is worth less than a dollar in your hand now, because today’s dollar can be invested and grow. Present value measures that gap.
How Present Value Works
To find present value, you “discount” a future amount back to today using a discount rate. The higher the rate, the more a future payment shrinks in today’s terms. The further away the payment, the smaller its present value.
For example, $10,000 due in 10 years is worth roughly $6,100 today at a 5% discount rate. You would only need to invest about $6,100 now to have $10,000 in a decade, so that is its present value.
Why Present Value Matters for Annuities
Present value is how insurers price guaranteed income. When you buy a single premium immediate annuity, the company calculates the present value of every future payment it promises and sets your premium accordingly.
It also explains a common surprise for lottery winners. The cash lump sum is simply the present value of the 29-year payment stream, which is why it looks so much smaller than the advertised jackpot. See our breakdown of lottery payout options for a full example.
