Calculator Use

Calculate the present value investment for a future value lump sum return, based on a constant interest rate per period and compounding. This is a special instance of a present value calculation where payments = 0. The present value is the total amount that a future amount of money is worth right now.

commonly a period will be a year but it can be any time interval you want as long as all inputs are consistent.
Future Value (FV)
is the future value sum of your investment that you want to find a present value for
Number of Periods (t)
commonly this will be number of years but periods can be any time unit.  Enter whole numbers or use decimals for partial periods such as months for example, 7.5 years is 7 yr 6 mo.
Interest Rate (R)
is the annual nominal interest rate or "stated rate" in percent. r = R/100, the interest rate in decimal
Compounding (m)
is the number of times compounding occurs per period. If a period is a year then annually=1, quarterly=4, monthly=12, daily = 365, etc.
Continuous Compounding
is when the frequency of compounding (m) is increased up to infinity. Enter c, C or Continuous for m.
Rate (i)
i = (r/m); interest rate per compounding period.
Total Number of Periods (n)
n = mt; is the total number of compounding periods for the life of the investment.
Present Value (PV)
the calculated present value of your future value amount
Present Value Interest Factor that accounts for your input Number of Periods, Interest Rate and Compounding Frequency and can now be applied to other future value amounts to find the present value under the same conditions.
Time period. Typcially a period will be a year but it can be any time interval as long as all inputs are in the same time unit.
Future Value (FV)
Future value of a lump sum.
Number of Periods (t)
Number of years or time periods.
For a perpetual annuity t approaches infinity. For "Number of Periods (t)" enter p or perpetuity.
Interest Rate (R)
The annual nominal interest rate or stated rate per period, as a percentage.
Compounding (m)
The number of times compounding occurs per period. If a period is a year enter:
1 for annual compounding
4 for quarterly compounding
12 for monthly compounding
365 for daily compounding
Continuous Compounding
For frequency of compounding (m) approaches infinity. For "Compounding (m)" enter c or continuous.
Payment Amount (PMT)
The amount of the cash flow annuity payment each period.
Growth Rate (G)
If this is a growing annuity, enter the growth rate per period of payments in percentage form.
Payments per Period (Payment Frequency, q)
How often payments are made each period. If a period is a year enter:
1 for annual payments
4 for quarterly payments
12 for monthly payments
365 for daily payments
Payments at Period (Type)
Specify whether payments occur at the end of each payment period (ordinary annuity, in arrears) or if payments occur at the beginning of each payment period (annuity due, in advance)
Present Value (PV)
The present value of any future value lump sum plus future cash flows (payments)

Present Value Formula for a Future Value:

\( PV = \dfrac{FV}{(1+\frac{r}{m})^{mt}} \)

where r=R/100 and is generally applied with r as the yearly interest rate, t the number of years and m the number of compounding intervals per year. We can reduce this to the more general

\( PV = \dfrac{FV}{(1+i)^n} \)

where i=r/m and n=mt with i the rate per compounding period and n the number of compounding periods.

When m approaches infinity, m → ∞ (continuous compounding)

\( PV = \dfrac{FV}{e^{rt}} \)

See the present value calculator for derivations of present value formulas.

Example Present Value Calculations for a Lump Sum Investment:

You want an investment to have a value of $10,000 in 2 years. The account will earn 6.25% per year compounded monthly. You want to know the value of your investment now to acheive this or, the present value of your investment account.

  • Investment Value in 2 years FV = $10,000
  • Interest Rate R = 6.25%, r = 0.0625
  • Number of Periods (years) t = 2
  • Compounding per Period (per year) m = 12
\( PV = \dfrac{\$10,000}{(1+\frac{0.0625}{12})^{12\times2}}= \$8,827.83 \)
