Calculating Present Value

Annuity due refers to payments that occur regularly at the beginning of each period. Rent is a classic example of an annuity due because it’s paid at the beginning of each month. Most states require annuity purchasing companies to disclose the difference between the present value of your future payments and the amount they offer you. For example, suppose you want to know what interest rate (compounded semi-annually) you need to earn in order to accumulate $10,000 at the end of 3 years, with an investment of $7,049.60 today. In present value situations, the interest rate is often called the discount rate. This is because we are discounting a future value back to the present.

Please pay attention that the 4th argument is omitted because the future value is not included in the calculation. When calculating the present value of annuity, i.e. a series of even cash flows, the key point is to be consistent with rate and nper supplied to a PV formula. When putting deposits to a saving account, paying home mortgage and the like, you usually make the same payments at regular intervals, e.g. weekly, monthly, quarterly, or yearly. Such series of payments made at equal intervals is called an annuity. Let us take another example of a project having a life of 5 years with the following cash flow.

How do I calculate the present value of a single amount?

Simply put, the money today is worth more than the same money tomorrow because of the passage of time. Future value can relate to the future cash inflows from investing today’s money, or the future payment required to repay money borrowed today. In many cases, a risk-free rate of return is determined and used as the discount rate, which is often called the hurdle rate.

Make sure the units of nper and rate are consistent, e.g., in case of monthly interest rate the number of periods of investment should also be in months. If type is omitted or 0 is the input, payments are made at period end. The PV Function is a present value formula widely used financial functionin Microsoft Excel. Except for minor differences due to rounding, answers to equations below will be the same whether they are computed using a financial calculator, computer software, PV tables, or the formulas.

Present Value of a Single Amount Outline

It is the return you give up now in the expectation of receiving that return in the future. Finally, if the alternative to receiving $1,000 one year from now is to buy a bond, we would use the yield of the bond as the interest rate. Thus, the $627.41 equates the two alternatives such that the returns for similarly risky investments are equal. Together, these values can help you determine how much you need to put into an annuity to generate the types of income streams you want out of it.

If we are using lower discount rate, then it allows the present values in the discount future to have higher values. The operation of evaluating a present value into the future value is called a capitalization (how much will $100 today be worth in 5 years?). The reverse operation—evaluating the present value of a future amount of money—is called a discounting (how much will $100 received in 5 years—at a lottery for example—be worth today?). Below is an illustration of what the Net Present Value of a series of cash flows looks like. As you can see, the Future Value of cash flows are listed across the top of the diagram and the Present Value of cash flows are shown in blue bars along the bottom of the diagram.

Present Value of Future Money

Getting early access to these funds can help you eliminate debt, make car repairs, or put a down payment on a home. The present value of an annuity is based on a concept called the time value of money. According to the Harvard Business School, the theory behind the time value of money is that an amount of cash is worth more now than the promise of that same amount in the future.
