The Present Value (Worth) of 1 is a fundamental concept in finance that determines the current value of an amount of money that is expected to be received in the future. This calculation is made by applying a specific compound interest rate. It aids investors, financial analysts, and economists in assessing the value of future cash flows in today’s terms.
Formula for Present Value
The present value (\(PV\)) of an amount to be received in the future can be calculated using the following formula:
Where:
- \( PV \) = Present Value
- \( FV \) = Future Value
- \( i \) = Interest Rate per period
- \( n \) = Number of periods
Examples of Present Value Calculation
Example 1:
If you are set to receive $1 one year from now and the interest rate is 12%, the present value is:
Thus, the present value of one dollar received in one year is approximately $0.89286.
Example 2:
For an amount to be received in two years with the same 12% interest rate:
Here, the present value of one dollar received in two years is approximately $0.79719.
Importance in Finance
Investment Decisions
The concept of present value allows businesses and investors to make informed decisions regarding investments. By discounting future cash flows back to their present value, one can determine whether an investment is worthwhile.
Valuation of Cash Flows
Risk Assessment
Present value calculations help in assessing the risk associated with future cash flows. Higher interest rates typically reflect higher risk, leading to lower present values and thus influencing investment decisions.
Historical Context
The concept of present value has its roots in the time value of money principle, which has been recognized for centuries. This principle suggests that a dollar today is worth more than a dollar in the future due to its potential earning capacity.

Frequently Asked Questions
What is the difference between present value and future value?
Present value represents the current worth of a future amount, while future value denotes what an investment made today will be worth in the future, considering a specific interest rate.
How does the interest rate affect the present value?
A higher interest rate decreases the present value of a future amount since money today can earn more through investment, necessitating a greater discounting of future value.
Summary
The present value (worth) of 1 is an invaluable tool in finance, aiding in the evaluation and comparison of future cash flows by considering the time value of money. By applying compound interest rates, it allows for accurate financial planning and investment analysis.
