Guide to Calculating Return on Investment (ROI)

To determine which investments or expenses make the most sense for your business, you need to calculate their return on investment (ROI), that is, the amount of profit earned or cost saved for any given use of money. By calculating ROI, you can:

1. Cancel services that provide little or no return to your bottom line.
2. Focus on the products and services that help your business the most.
3. Use previous results to make better business decisions in the future.

Consider using the "net present value"

Cash today is generally worth more than cash tomorrow due to inflation, so you may want to include that cost in your calculations. Doing so gives you the "net present value" (NPV) of a project, which is somewhat more accurate than ROI.

Use Investopedia's NPV calculator.

Tips & Tactics

Helpful advice for making the most of this Guide

• If you plan to sell your business, prospective buyers will want to know your ROI so they can evaluate your listing price.
• Don't be blinded by high percentages; keep the bottom line in mind. Which is better: a 200 percent ROI on a $5,000 investment or a 120 percent ROI on a $100,000 investment?
• Don't forget to include the cost of your labor in any ROI calculation — otherwise you'll get a warped perspective of your company's financial status.
