The Present Value (PV) calculator computes the present value (PV) based on the Future Value (FV), Number of Periods (n) and the Interest Rate per Period (r).
INSTRUCTIONS: Choose units and enter the following:
- (FV) Future Value
- (n) Number of Periods in the future
- (r) Interest Rate per Period
Present Value (PV): The calculator returns the Present Value in U.S. dollars. However this can be automatically converted to other currencies via the pull-down menu.
The Math / Science
The Present Value equation computes the present value of money planned or estimated in the future that has been discounted to reflect its current value as if it existed today. The formula for the present value is:
`PV = "FV"/(1+r)^n`
Where:
- PV = Present Value
- FV = Future Value - the value of the money at some point in the future
- n = Number of Periods of the investment
- r = Rate of Interest per Period
This estimation technique supports the Program Management assessment of project fiscal status as defined in the Earned Value Management approach. These calculations are used to make comparisons between cash flows that do not occur on the same schedule
EXAMPLE
If a worker is to receive $ 2000 in 4 year, and the effective annual interest rate during this period is 11%, then the present value of this amount is $ 1462.38
Basic Investor Calculators
- Black-Scholes Equation: Compute the Call and Put Option based on the Black-Scholes equation and the stock or spot price, strike price, number of years to maturity, percent volatility and the risk-free rate.
- 30 Day Yield Equation: Computes the SEC's 30 day yield function for bond funds based on the income in the prior 30 days, accrued expenses in the prior 30 days, outstanding shares and max price per share.
- Investment Return Rate: Computes the return rate based on the beginning and end price and dividends paid.
- Inflation Adjusted Return: Computes the return rate based on the Inflation Rate and the Investment Return.
- Present Value- computes the present value of a fixed annuity.
- Future Value- computes the future value of a fixed annuity.
- Interest Rate for Future Value - computes the annual fixed interest rate required for a present value to accrue to the future value over a number of periods.
- Number of Periods Required - computes the number of periods required to achieve a future value from a present value at a fixed annual interest rate.
- Precious Metal Value - computes the current market value of gold, platinum, silver and palladium based on bullion weight and purity.
- Credit Card Equation - computes the time required to payoff a debt based on an interest rate, initial balance and monthly payment.
- Currency Conversion - computes the current value of a currency amount (e.g., $2,000 US dollars) in Euros, Great Britain Pounds, Canadian Dollars, Yuan, Yen, Rubbles, Swiss Francs, Australian Dollars, South African Rands, Brazial Reals, Mexican Pesos, Indian Rupees and U.S. dollars.
