Present Value Calculator

Present value (PV) is what a sum of money you'll receive in the future is worth in today's terms. It rests on the time value of money: a dollar today is worth more than a dollar in the future, because today's dollar can be invested to grow. Present value reverses that growth — it 'discounts' a future amount back to the present using an assumed rate of return.

The logic is the mirror image of future value. If money grows at a certain rate over time, then to find what a future amount is worth now, you divide it by that growth factor. A $10,000 payment due in five years, discounted at 6%, is worth about $7,473 today — meaning $7,473 invested at 6% would grow to $10,000 in five years. The further away the money and the higher the discount rate, the less it's worth today.

The discount rate is the key assumption and the most subjective part. It represents the return you could earn on money if you had it now, or the risk of the future payment. A higher rate — reflecting better alternative investments or more risk — produces a lower present value, while a lower rate makes future money worth more today. Choosing the right rate is central to any present-value analysis.

Present value underpins a huge range of financial decisions. It's how analysts value investments and businesses (discounting future cash flows to today), how you compare a lump sum now against payments over time — like a lottery payout or pension choice — and how bonds and loans are priced. Whenever you must compare money available at different points in time, present value puts everything on a common footing: today's dollars.

For a stream of future payments rather than a single sum, you discount each payment to the present and add them up, which gives the net present value (NPV) used in capital budgeting. This calculator handles a single future amount; the same principle scales to any series of cash flows. As always, present value is only as reliable as the discount rate you assume, so it's wise to test a range.
