These sorts of investments usually have a single initial cost—typically the cost of the asset being purchased. You are considering buying an electric juicer for your business which will save you time and effort compared to juicing the lemons by hand.

Determine a time period to analyze. As noted above, businesses and individuals make investments with the goal of making money in the long run. To determine the NPV for your investment, you'll need to specify a time period during which you're trying to determine whether the investment will pay for itself. This time period may be measured in any unit of time, but for most financial calculations the unit of measure is years. According to most reviews, the juicer works great, but usually breaks after about 3 years.

Estimate your cash inflow for each time period. You'll need to estimate how much money your investment will make you during each time period for which it's earning you money.

These amounts or "cash inflows" can be specific, known values, or they can be estimates. In the latter case, companies and financial firms sometimes devote a great deal of time and effort to getting an accurate estimate, hiring industry experts, analysts, and so on. Let's continue with our lemonade stand example. Determine the appropriate discount rate. In general, a given amount of money is worth more now than it is in the future. This is because the money you have today can be invested in an interest-earning account and gain value over time.

This is called your "discount rate" and is expressed as a decimal, rather than a percent. In simpler situations, you can usually just use the return rate on a savings account, stock investment, etc. In this case, 0. Discount your cash inflows. In the lemonade example, you're analyzing 3 years, so you'll need to use your formula 3 times.

Sum your discounted cash flows and subtract your initial investment. Finally, to get the total NPV for the project, purchase, or investment you're analyzing, you'll need to add up all of your discounted cash flows and subtract your initial investment. If it's negative, you'll make less money. For the lemonade stand example, the final projected NPV value of the juicer would be: Determine whether or not to make the investment.

The NPV basically tells you the value of your future payout minus your invested cash amount. Use that number to determine whether it's a good investment or not.

In general, if the NPV for your investment is a positive number, then your investment will be more profitable than putting the money in your alternate investment and you should accept it. If the NPV is negative, your money is better invested elsewhere, and your proposed investment should be rejected. Note that these are generalities—in the real world, much more usually goes into the process of determining whether a certain investment is a wise idea.

Since this is positive, you'll probably decide to buy the juicer. Method 2. Add up your expected expenses to find your cash outflow. To get a more accurate picture of your present value, consider the various expenses you might need to pay.
