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%. Keep reading to find out how to work out the present value and what’s the equation for it. A present value of 1 table that employs a standard set of interest rates and time periods appears next.
Calculating Future Value vs. Present Value
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 what is the difference between a budget and a standard 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.
- The present value is the amount you would need to invest now, at a known interest and compounding rate, so that you have a specific amount of money at a specific point in the future.
- Assume an investment of money with a known annual discount rate in the form of an interest rate on a bank deposit, hence annual periodicity, and known (or estimated) future value of $100,000.
- The present value of an amount of money is worth more in the future when it is invested and earns interest.
- Annuity denotes a series of equal payments or receipts, which we have to pay at even intervals, for example, rental payments or loans.

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.
Present Value Formula and Calculation
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.
Determining the Discount Rate
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.
For example, $1,000 today should be worth more than $1,000 five years from now because today’s $1,000 can be invested for those five years and earn a return. If, let’s say, the $1,000 earns 5% a year, compounded annually, it will be worth about $1,276 in five years. Present value is based on the concept that a particular sum of money today is likely to be worth more than the same amount in the future, also known as the time value of money. Conversely, a particular sum to be received in the future will not be worth as much as that same sum today.
When using this present value formula is important that your time period, interest rate, and compounding frequency are all in the same time unit. Assume an investment of money with a known annual discount rate in the form of an interest rate on a bank deposit, hence annual periodicity, and known (or estimated) future value of $100,000. What is the present value of this investment if it is expected to receive this future value of $100,000 in 1, 2, 3, 5, or 10 years from now?

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.
