Present Value

Present value (PV) is the current value of a future sum of money or stream of cash flows given a specified rate of return. Future cash flows are discounted at the discount rate, and the higher the discount rate, the lower the present value of the future cash flows. Determining the appropriate discount rate is the key to properly valuing future cash flows, whether they be earnings or debt obligations.

Present value is the concept that states an amount of money today is worth more than that same amount in the future. In other words, money received in the future is not worth as much as an equal amount received today.

Receiving $1,000 today is worth more than $1,000 five years from now. Why? An investor can invest the $1,000 today and presumably earn a rate of return over the next five years. Present value takes into account any interest rate an investment might earn.

For example, if an investor receives $1,000 today and can earn a rate of return of 5 per cent per year, the $1,000 today is certainly worth more than receiving $1,000 five years from now. If an investor waited five years for $1,000, there would be an opportunity cost or the investor would lose out on the rate of return for the five years. Inflation is the process in which prices of goods and services rise over time. If you receive money today, you can buy goods at today’s prices. Presumably, inflation will cause the price of goods to rise in the future, which would lower the purchasing power of your money.

Money not spent today could be expected to lose value in the future by some implied annual rate, which could be inflation or the rate of return if the money was invested. The present value formula discounts the future value to today’s dollars by factoring in the implied annual rate from either inflation or the rate of return that could be achieved if a sum was invested.

The discount rate is the investment rate of return that is applied to the present value calculation. In other words, the discount rate would be the forgone rate of return if an investor chose to accept an amount in the future versus the same amount today. The discount rate that is chosen for the present value calculation is highly subjective because it’s the expected rate of return you’d receive if you had invested today’s dollars for a period of time.

In many cases, a risk-free rate of return is determined and used as the discount rate, which is often called the hurdle rate. The rate represents the rate of return that the investment or project would need to earn in order to be worth pursuing. A U.S. Treasury bond rate is often used as the risk-free rate because Treasuries are backed by the U.S. government. So, for example, if a two-year Treasury paid 2 per cent interest or yield, the investment would need to at least earn more than 2 per cent to justify the risk.

The discount rate is the sum of the time value and a relevant interest rate that mathematically increases future value in nominal or absolute terms. Conversely, the discount rate is used to work out future value in terms of present value, allowing a lender to settle on the fair amount of any future earnings or obligations in relation to the present value of the capital. The word “discount” refers to future value being discounted to present value.

The calculation of discounted or present value is extremely important in many financial calculations. For example, net present value, bond yields, and pension obligations all rely on discounted or present value. Learning how to use a financial calculator to make present value calculations can help you decide whether you should accept such offers as a cash rebate, 0 per cent financing on the purchase of a car, or pay points on a mortgage.
