# What is NPV and profitability index?

## What is NPV and profitability index?

Net present value tells us what a stream of cash flows is worth based on a discount rate, or the rate of return needed to justify an investment. The profitability index helps make it possible to directly compare the NPV of one project to the NPV of another to find the project that offers the best rate of return.

## What is the formula of profitability index?

Therefore, the profitability index formula divides the present value (PV) of the project’s future cash flows by the initial investment.

How does PI relate to NPV?

Generally speaking, a positive NPV will correspond with a PI greater than one, while a negative NPV will track with a PI below one. The main difference between NPV and profitability index is that the PI is represented as a ratio, so it won’t indicate the cash flow size.

### How profitability index is superior to NPV?

The PI allows you to compare the profitability of two properties without regard to the amount of money invested in each. NPV, on the other hand, suggests exactly how profitable an investment will be in comparison to alternatives and provides an actual cash flow estimation in dollars.

### Is NPV same as profit?

NPV is the sum of all the discounted future cash flows. Because of its simplicity, NPV is a useful tool to determine whether a project or investment will result in a net profit or a loss. A positive NPV results in profit, while a negative NPV results in a loss.

Which method is better NPV or PI?

For example, in situations where two, mutually exclusive, projects deliver the same amount of money in terms of NPV, but one project costs twice as much as another. This is when the profitability index (PI) gives the best answer.

## Which is better profitability index or NPV?

Conclusion. NPV is the most successful and reliable method of investment evaluation, compared to other methods such as the payback period, the rate of return, internal rate of return (and Profitability Index).

## Why is NPV the most accurate?

Net present value uses discounted cash flows in the analysis, which makes the net present value more precise than of any of the capital budgeting methods as it considers both the risk and time variables.

Is NPV the same as profit?

### How do you analyze NPV?

If the NPV of a project or investment is positive, it means that the discounted present value of all future cash flows related to that project or investment will be positive, and therefore attractive. To calculate NPV, you need to estimate future cash flows for each period and determine the correct discount rate.

### How do you calculate profitability index in Excel?

Profitability Index = (Net Present value + Initial investment) / Initial investment. Profitability Index = 1 + (Net Present value / Initial investment)
