What is ROI?
Understanding the Basics
Return on Investment (ROI) measures the profitability of an investment. It’s a simple percentage that shows how much profit you’ve earned compared to the cost of your investment. The ROI formula is straightforward:
ROI = (Net Profit / Investment Cost) x 100
For example, if you invest $1,000 in a marketing campaign and earn $1,500, your net profit is $500. Plugging it into the formula: ($500 / $1,000) x 100 = 50% ROI. A simple ROI calculator USA online automates this process, saving you time and effort.

Real-Life Example: Using ROI Calculator for a Small Business
Meet Sarah, a small business owner in Texas. She invested $20,000 in a digital marketing campaign to boost her e-commerce store’s sales. After three months, the campaign generated $28,000 in revenue. Using a simple ROI calculator USA online, Sarah inputs her data:
Investment Type | Cost ($) | Revenue ($) | Net Profit ($) | ROI (%) |
---|---|---|---|---|
Digital Marketing | 20,000 | 28,000 | 8,000 | 40% |
The calculator shows a 40% ROI, meaning Sarah earned 40 cents for every dollar spent. Encouraged by this, she compares the campaign’s ROI to a previous one (25% ROI) and decides to double down on digital marketing. Without the calculator, Sarah would’ve spent hours crunching numbers or guessing her returns.
