The interest rate selected in the table can be based on the current amount the investor is obtaining from other investments, the corporate cost of capital, or some other measure. Let’s assume we have a series of equal present values that we will call payments (PMT) for n periods at a constant interest rate i. We can calculate FV of the series of payments 1 through n using formula (1) to add up the individual future values. A mentioned, the discount rate is the rate of return you use in the present value calculation. It represents your forgone rate of return if you chose to accept an amount in the future vs. the same amount today. The discount rate is highly subjective because it’s simply the rate of return you might expect to receive if you invested today’s dollars for a period of time, which can only be estimated.

Calculator Use

Instead of a future value of $15,000, perhaps you want to find the present value of a future value of $20,000. It applies compound interest, which means that interest increases exponentially over subsequent periods. Present value is also useful when you need to estimate how much to invest now in order to meet a certain future goal, for example, when buying a car or a home. So, if you’re wondering how much your future earnings are worth today, keep reading to find out how to calculate present value. To find the present value of $1 find the appropriate period and rate in the tables below. You can then look up PV in the table and use this present value factor to calculate the present value of an investment amount.

In other words, to maintain the same present value the interest rate would need to increase parallel to the increasing number of years one is locked into an investment. In short, a greater discount rate is required to justify a longer term investment decision. Present value calculator is a tool that helps you estimate the current value of a stream of cash flows or a future payment if you know their rate of return. A present value of 1 table states the present value discount rates that are used for various combinations of interest rates and time periods. A discount rate selected from this table is then multiplied by a cash sum to be received at a future date, to arrive at its present value.

Present Value of an Annuity Formula Derivation

In the present value formula shown above, we’re assuming that you know the future value and are solving for present value. Now you know how to estimate the present value of your future income on your own, or you can simply use our present value calculator. Present value tables are one of many time value of money tables, discover another at the links below. This factor includes the given interest and periods and can now be multiplied by any amount of money to find the cooresponding present value.

PV tables are used to provide a solution for the part of the present value formula shown in red, this is sometimes referred to as the present value factor. They provide the value now of 1 received at the end of period n at a discount rate of i%. The purpose of the present value tables is to make it possible to carry out present value calculations without the use of a financial calculator.

The default calculation above asks what is the present value of a future value amount of $15,000 invested for 3.5 years, compounded monthly at an annual interest rate of 5.25%.
