Present Value Calculator

Estimate what a future lump sum is worth today. Enter the future amount, an annual discount rate, the time until you receive it and a compounding frequency to see the present value, the discount amount and the discount factor.

Results depend on the discount rate, time period and compounding frequency you choose.

Your assumptions

Enter the amount expected at the end of the selected period.

Nominal annual rate, 0 to 100, used to discount the future amount. It is an assumption, not an official or guaranteed rate.

How long until the future amount is received, 0 to 100. Fractional years such as 2.5 are allowed.

The nominal annual rate is divided by the number of periods per year. Daily uses 365 periods.

Display format only. Amounts are not converted between currencies.

  • One future lump sum; no other cash flows.
  • Constant nominal rate and one compounding frequency.
  • No taxes, fees, inflation adjustment or currency conversion.

How the Present Value Formula Works

r = APR / 100 i = r / m n = m × t PV = FV / (1 + i)^n = FV / (1 + r/m)^(m×t) Discount Factor = 1 / (1 + i)^n (= PV / FV when FV > 0) Discount Amount = FV − PV Discount % = (FV − PV) / FV × 100 (FV > 0)

FV is the future value, PV the present value, r the annual rate as a decimal, m the compounding periods per year, t the time in years, i the rate per period and n the total number of periods. n may be fractional when t is fractional, and the calculator uses it exactly as entered.

  1. Enter the future amount you expect to receive.
  2. Convert the annual discount percentage to a decimal.
  3. Select how often the rate compounds.
  4. Divide the annual rate by the periods per year to get the periodic rate.
  5. Multiply the periods per year by the years to get the total periods.
  6. Divide the future value by (1 + i)^n.
  7. Subtract the present value from the future value to get the discount amount.

Discounting reverses the growth used in future-value calculations under the same assumptions. With a positive rate and a positive time period, present value is below future value. At a 0% rate, or a 0-year period, no discounting occurs and the present value equals the future value. Higher positive rates and longer periods each lower the present value when the other inputs stay the same. The calculator does not choose a rate for you, and no single rate suits every decision.

What Is Present Value?

Present value is the estimated value today of an amount of money expected in the future, calculated with a chosen discount rate and time horizon. It rests on the time value of money: an amount received later is not treated as equal to the same amount today. The result depends entirely on your discounting assumptions. It does not set a market price or a guaranteed value.

How to Use the Present Value Calculator

  • Future Value: the amount you expect to receive.
  • Annual Discount Rate: the nominal yearly rate you want to apply.
  • Time Period: years until receipt, including fractions.
  • Compounding Frequency: annually, semiannually, quarterly, monthly or daily.
  • Display Currency: the symbol and number format.

Press Calculate Present Value to see the result, the discount factor and the discount amount, and read the breakdown to see each substituted value. The currency selector changes formatting only; it does not perform foreign-exchange conversion.

Present Value Calculation Example

Suppose a future value of $10,000, a 5% nominal annual discount rate, 10 years and annual compounding, with fees and taxes excluded:

PV = 10,000 / (1 + 0.05)^10 = 10,000 / 1.628895 ≈ 6,139.13

The present value is about $6,139.13, the discount amount is about $3,860.87, the discount factor is about 0.613913 and the discount percentage is about 38.61%. In other words, $10,000 received in ten years is worth about $6,139.13 today at a 5% annual rate. Change the rate, time or compounding assumption and the result changes.

How the Discount Rate Affects Present Value

A higher positive discount rate shrinks the present value of the same future amount over the same period, because the future sum is divided by a larger growth factor. Which rate is appropriate depends on the context and your own model. This calculator neither selects nor recommends one, and the illustrative figures here are not market standards.

How Time Affects Present Value

With a positive rate and a positive future amount, a longer wait lowers the present value, since more periods of discounting apply. A period of zero years means the amount is due today in this simplified model, so the present value equals the future value.

How Compounding Frequency Changes the Calculation

The nominal annual rate is split across the compounding periods. Annual compounding uses 1 period per year, semiannual 2, quarterly 4, monthly 12 and daily 365 (a simplified convention that ignores leap years). More frequent compounding raises the number of periods and lowers the periodic rate, which changes the result slightly. For example, 12% compounded monthly for one year discounts $10,000 to about $8,874.49. If you use this for a real decision, match the compounding assumption to your financial model.

What Is a Discount Factor?

The discount factor is the multiplier that turns a future value into a present value. It is the reciprocal of the growth factor under the chosen rate and compounding: 1 / (1 + i)^n. In the example it is about 0.613913, and 10,000 × 0.613913 ≈ 6,139.13.

Present Value vs. Future Value

Present value expresses a future sum in today's terms by discounting it. Future value projects a current amount forward to a later date using a rate assumption. They are two directions of the same relationship.

What This Present Value Calculator Includes and Excludes

It discounts one future lump sum at a fixed nominal annual rate with the compounding frequency you choose. It excludes:

  • multiple future cash flows;
  • annuity payments;
  • uneven cash-flow schedules;
  • taxes and fees;
  • inflation adjustments separate from the discount rate;
  • foreign-exchange conversion;
  • risk assessment;
  • changes to the discount rate over time;
  • any guarantee about actual financial value.

More complex valuations may need different models and assumptions.

How to Interpret Your Results

The present value is the estimated worth today of the future amount under your assumptions. The discount amount is how much lower it is, the discount percentage expresses that as a share of the future value, and the discount factor is the multiplier applied. All of them depend on the rate, time and compounding you entered. Treat them as estimates, not as personalized financial recommendations or guaranteed market valuations.

Frequently asked questions

What is a present value calculator?

It estimates today's value of a future lump sum using a discount rate, a time period and a compounding assumption.

How do I calculate present value?

Divide the future amount by the growth factor for the selected rate, compounding frequency and time: PV = FV / (1 + r/m)^(m×t).

What is the present value formula?

PV = FV / (1 + r/m)^(mt), where FV is the future value, r is the annual rate as a decimal, m is the compounding periods per year and t is the time in years.

What happens if the discount rate is 0%?

The present value equals the future value, because no discounting occurs in the model.

How does the discount rate affect present value?

A higher positive discount rate generally lowers the present value when the future amount and period are unchanged.

Why does time affect present value?

At a fixed positive discount rate, a longer time before the payment generally produces a lower present value.

What is the difference between present value and future value?

Present value expresses a future amount in today's terms. Future value projects an amount forward to a later date using a rate assumption.

What is a discount factor?

It is the multiplier applied to the future value to get the present value, equal to 1 / (1 + i)^n.

Does compounding frequency affect present value?

Yes. For the same nominal annual rate and a positive time period, the frequency changes the periodic rate and the number of periods, which changes the result.

Does the calculator account for inflation and taxes?

No. It does not separately model inflation, taxes, fees or other costs. You can choose a discount rate that suits your own model, but the calculator does not determine the appropriate rate.
