Present Value Calculator

Find out what a future lump sum — or a future lump sum plus a stream of periodic payments — is worth in today's dollars, given a discount rate and time horizon.

Results from this calculator are estimates provided for general informational purposes only, based on formulas, rates, and standards commonly accepted as of 2026. Figures may differ slightly from other calculators or professional sources due to rounding methods, differing assumptions, or regional regulations, and rules may change over time. Always consult a qualified professional — such as a financial advisor, healthcare provider, or other relevant specialist — before making decisions based on these results.

The lump sum amount you expect to receive (or need) at the end of the time period.
$
Optional. An equal payment received at the end of every compounding period (an ordinary annuity), added on top of the lump-sum future value.
$
Your annual discount rate — the return you could earn elsewhere, or your cost of capital. Higher rates shrink present value more.
%
How many years until the future value is received.
How often the discount rate compounds within a year. More frequent compounding lowers the present value slightly at the same nominal rate.

Example

To have $50,000 in 10 years at 6% annual interest (compounded monthly), you would need to invest $27,481.64 today — a discount of $22,518, or 45.0% of the future value.

How the lump sum's value grows from present value today to future value

What is a Present Value Calculator?

A present value calculator answers the core question behind the time value of money: what is a future sum of money worth today? Because money available now can be invested to earn a return, a dollar received in the future is worth less than a dollar in hand today — present value tells you exactly how much less, given a discount rate and a time horizon.

This calculator handles both a future lump sum and, optionally, a stream of equal periodic payments (an ordinary annuity) — useful for valuing things like a future inheritance, a bond's maturity value, a pension payout, or a structured settlement in today's dollars.

How Present Value Is Calculated

For a single future lump sum, present value discounts the future amount back by the compounding factor over the number of periods:

PV = FV ÷ (1 + r)ⁿ

For a stream of equal periodic payments (an ordinary annuity), each payment is individually discounted and summed, which simplifies to:

PV(annuity) = PMT × [1 − (1 + r)⁻ⁿ] ÷ r
  • PV — present value (today's worth)
  • FV — future value (the lump sum received later)
  • PMT — the periodic payment amount
  • r — discount rate per compounding period (annual rate ÷ periods per year)
  • n — total number of compounding periods (years × periods per year)

Why the Discount Rate Matters So Much

Present value is extremely sensitive to the discount rate you choose, especially over long time horizons. $100,000 received in 20 years is worth about $55,368 today at a 3% discount rate, but only about $23,880 today at an 8% discount rate — more than double the difference. Choosing the right discount rate (often your opportunity cost of capital, or a "risk-free" rate like Treasury yields for very safe cash flows) is the single most important judgment call in any present value calculation.

Compounding Frequency

Present value is also affected — more subtly — by how often the discount rate compounds. A 6% annual rate compounded monthly behaves slightly differently than the same 6% compounded annually, because the nominal rate gets divided into smaller periods that compound more often. More frequent compounding at the same nominal rate produces a slightly lower present value (since the effective discount rate is marginally higher).

Common Uses for Present Value

Present value calculations underpin most of corporate finance and personal financial planning: valuing a bond by discounting its coupon payments and face value, deciding whether a lottery lump-sum offer beats the annuity option, comparing loan offers, valuing a pension or structured settlement, and — combined across many future cash flows — computing net present value (NPV) to evaluate whether an investment project creates value.

Example — Your Current Inputs

To have $50,000 in 10 years at 6% annual interest (compounded monthly), you would need to invest $27,481.64 today — a discount of $22,518, or 45.0% of the future value.

Additional Example — Lottery Lump Sum vs. Annuity

A lottery advertises a $1,000,000 jackpot paid as $50,000 per year for 20 years, or you can take a lump sum today. At a 6% discount rate, the present value of that 20-year, $50,000 annuity is about $573,500 — meaning a lump-sum offer anywhere near or above that figure could be the financially better choice, depending on your ability to invest it yourself at a similar or better return.

About These Parameters

Future Value
The lump sum amount you expect to receive (or need) at the end of the time period — a bond's face value, a target savings goal, or a future payout.
Periodic Payment
Optional. If the cash flow also includes equal payments at the end of every compounding period (such as bond coupons or annuity installments), enter the payment amount here to add its present value to the total.
Discount Rate
The annual rate used to discount future cash flows — typically your opportunity cost of capital, a comparable investment return, or a risk-free benchmark rate.
Number of Years & Compounding
How far in the future the value is received, and how often the discount rate compounds within each year. Monthly compounding is the most common default.

Frequently Asked Questions

What discount rate should I use?

There's no single right answer — it should reflect what you could reasonably earn on an alternative investment of similar risk, or your personal/company cost of capital. Very safe, near-certain cash flows are often discounted at a low "risk-free" rate; riskier or less certain cash flows warrant a higher rate.

What's the difference between present value and net present value (NPV)?

Present value discounts a single future amount (or a simple annuity) back to today. Net present value extends this to a full project: it sums the present value of every expected cash inflow and outflow, then subtracts the initial investment, to show whether a project creates or destroys value overall.

Why is present value always less than future value?

Because money available today can be invested to grow, a dollar today is worth more than a dollar promised later — as long as the discount rate is positive, present value will always be smaller than the future value it's derived from.

How does inflation relate to the discount rate?

Inflation is one component of a "real world" discount rate — if you want your present value to reflect actual purchasing power, use a real (inflation-adjusted) discount rate; if you're comparing against nominal investment returns, use a nominal rate that already includes expected inflation.
