It is always best practice to calculate the numbers and enter them directly from the calculator’s memory as this avoids rounding errors. Note that your answers could be off by a small amount if you simply copied the numbers and re-entered them. Now solve for FV and you will get 643.49. Therefore, to get the future value we simple enter the following: N = 5, I/YR = 8 (note that we use the discount rate, not the net rate), PV = -437.94, and PMT = 0. Now solve for FV and you will get 694.97.įor the graduated regular annuity, recall that we found that the present value was 437.94. Therefore, to get the future value we simple enter the following: N = 5, I/YR = 8 (note that we use the discount rate, not the net rate), PV = -472.98, and PMT = 0. The same applies to normal (all cash flows equal) annuities.įor the graduated annuity due, recall that we found that the present value was 472.98. In the examples from above, the future value will be in period 5, regardless of whether it is an annuity due or a regular annuity. The only thing to remember is that the future value of an annuity due is defined to be one per after the last cash flow. Simply find the present value and then calculate the future value of that number. Once one understands how to calculate the present value of a graduated annuity, then finding its future value is very easy. This method is more work, and it isn’t as practical if you have a lot of cash flows. Get the actual PV by dividing the result from step 4 by 1+ gĪlso, note that you can verify the results from above by treating the cash flows as an uneven cash flow stream.Enter the first payment amount into PMT.Enter N and I/YR, being sure to use the net rate for the interest rate. ![]() To recap the steps, here is how to find the present value of a graduated regular annuity on the HP 12C: Specifically, the net rate can be calculated using the following formula: However, because the rates compound over time, the adjustment is a bit more complex. Therefore, the "net" interest rate that we will use must be a combination of these two rates.īecause the two rates work in opposition to each other, we can approximate the correct rate to use by simply using the difference between the discount rate and the growth rate. The growth rate makes the cash flows larger, but the discount rate makes them smaller. The first thing to understand is that there are two opposing rates when dealing with graduated annuities: The growth rate and the discount rate. Fortunately, we can make the PV function do the work for us by altering the interest rate that we use. However, there are no functions that can calculate the present value or future value of a growing stream of cash flows. The HP 10BII makes that easy because it has built-in functions that automatically handle annuities. We have already seen how to calculate the present value and future value of annuities. You might wish to sell it to a third party and you should know how to determine its worth. These are often paid out in a structured settlement as a graduated annuity. You might want to know how to calculate the present value of a graduated annuity if you have, for example, a legal settlement from a lawsuit or insurance company. In fact, the growth rate can be positive, negative, or zero so this is really just a generalization of a typical annuity (which would have a zero growth rate). Any finite series of cash flows that are growing at a constant rate is a graduated (or, growing) annuity. Graduated annuities are found in many places including pensions that have built-in cost of living adjustments, lotteries such as PowerBall, and others. Annuity cash flows grow at 0% (i.e., they are constant), while graduated annuity cash flows grow at some nonzero rate. So, the two types of cash flows differ only in the growth rate of the cash flows. However, a graduated annuity (also called a growing annuity) is one in which the cash flows are not all the same, instead they are growing at a constant rate (any other series of cash flows is an uneven cash flow stream). Strictly speaking, an annuity is a series of equal cash flows, equally spaced in time. ![]() Are you a student?
