# How Can Excel Be Used to Calculate Present Value (PV)?

A key element of corporate budgeting, NPV provides a thorough method for determining whether a proposed project will add value or not.

For the purposes of this article, the discount rate will be determined by solving for the rate at which the NPV is equal to zero. By doing this, we can figure out a project’s or asset’s internal rate of return (IRR).

## Excel formula for PV

Once more, the Excel formula for calculating PV is =PV.

The following are some of the inputs for the Excel formula for present value (PV):

- RATE = Annual Percentage Interest
- NPER stands for Number of Payment Periods.
- PMT = Periodic Payment (if omitted, it is assumed to be zero, and FV must be present).
- [FV] stands for the investment’s future value; if omitted, it is assumed to be zero and PMT must be added.
- [TYPE] denotes the timing of payments (0, or if omitted—at the end of the period, or 1—at the start of the period)

For PV formulas, it’s important to keep in mind that any money paid out (outflows) should be a negative number. Inflows of cash are a positive number.

## Amount Offered

Let’s start by going over each NPV step in turn. The equation is:

NPV is calculated as “After-Tax Cash Flow / (1+r)t-Initial Investment.”

The after-tax cash flow for each period at time t is broken down and discounted by a certain rate, represented as r. The initial investment is then subtracted from the total of these discounted cash flows, yielding the current NPV. A value-added project is one that has an NPV greater than $0.

The project with the highest NPV should tip the scales in its favor when choosing between competing but comparable projects.

The concepts of NPV, IRR, and discount rate are all interrelated. You can predict the size and timing of cash flows with an NPV. When calculating the NPV, the weighted average cost of capital (WACC), represented by the letter r, is also known. You can solve for the NPV expressed as a percentage return when using an IRR because you are aware of the same information.

## Excel NPV vs PV Formula

Excel also allows you to compute net present value in addition to PV (NPV). Discounted future cash flows represent the present value. The difference between PV of cash flows and PV of cash outflows is known as net present value.

The primary distinction between PV and NPV is that the latter accounts for the initial outlay. The discount rate and a series of cash outflows and inflows are used in the NPV formula for Excel.

- Important distinctions between NPV and PV
- Excel’s PV calculation can only be applied to steady, unchanging cash flows.
- It is possible to apply NPV with varying cash flows.
- Regular annuities (payments at the end of the period) and annuities due can both be made using PV.
- Only payments or cash flows at the end of the period may be analyzed using NPVs.

## PV Formula Example in Excel

You can calculate how much would need to be invested today to achieve a goal like having $50,000 in your bank account in 10 years at a rate of 5% interest.

In Excel, cell A1 can be labeled “Years.” In addition, enter the number of years in cell B1 Enter 5% in cell B2 and label cell A2 “Interest Rate.” Place $50,000 in cell B3 and “Future Value” in cell A3, respectively.

With the provided data, the built-in function PV can quickly calculate the present value. Cell A4 should read “Present Value,” and cell B4 should contain the PV formula, which in our example is “=PV(B2,B1,0,B3).”

Since there are no additional payments, the “PMT” argument uses 0. Since you would have to deposit this money into your account, the present value is calculated to be ($30,695.66); because it is a cash outflow, it is shown as a negative amount. Excel will display the present value as an inflow if the future value was displayed as an outflow.

## Particular Considerations

If the interest rate and payment amount are based on different periods, adjustments must be made to the PV formula in Excel. The annual interest rate must be changed to a period rate, which is a common change that is required to make the PV formula in Excel function. The annual rate is divided by the number of periods in a year to achieve this.

For instance, if your PV formula payment is made monthly, you’ll need to divide your annual interest rate by 12 to convert it to a monthly payment. Additionally, the NPER, or number of periods, is 12 times 4 or 48 if you receive an annuity payment every month for four years.
