ROI formula explained
Return on Investment (ROI) measures how efficiently an investment generates profit. It compares the net profit earned with the original investment and expresses the result as a percentage, making it easy to compare different investment opportunities.
ROI formula
A positive ROI means your investment generated more money than it cost. A higher percentage indicates a more profitable investment.
Net profit formula
Net profit is the amount remaining after subtracting every cost associated with the investment, including operating or marketing expenses.
Example calculation
What is a good ROI?
A good ROI depends on the type of investment, risk level and time period. However, these ranges can help you quickly evaluate whether an investment is weak, acceptable, strong or excellent.
Negative
The investment lost money. Revenue did not cover the investment cost and additional expenses.
Low
The investment is profitable, but the return may not justify the risk, effort or time required.
Healthy
A solid return for many business activities, marketing campaigns and ecommerce investments.
Excellent
A strong return that may justify scaling, as long as profitability remains stable.
- ROI helps compare different investments using the same percentage metric.
- A high ROI is only useful if the profit calculation includes all real costs.
- Marketing campaigns should be evaluated by profit, not just revenue.
- MarginLab helps Shopify merchants understand the real profit behind products, campaigns and promotions.
Common ROI calculation mistakes
Many investors and ecommerce businesses overestimate their return because they forget important costs or focus only on revenue. These are the mistakes that most often produce misleading ROI calculations.
Ignoring hidden costs
Advertising, software subscriptions, shipping, transaction fees and operating expenses should all be included when calculating real ROI.
Looking only at revenue
High revenue does not automatically mean a successful investment. ROI should always be based on profit, not sales alone.
Ignoring time
A 50% ROI achieved over five years is very different from a 50% ROI achieved in three months. Always consider the investment period.
Using incomplete data
Missing expenses or inaccurate numbers can make ROI appear much higher than the real return generated by the investment.
Why ROI alone isn’t enough
Return on Investment is one of the most useful financial metrics, but it only tells part of the story. Two investments can have the same ROI while generating very different levels of profit, cash flow or long-term business value.
What ROI doesn’t show
- How long it took to achieve the return.
- Whether cash flow remained positive during the investment.
- The risk associated with the investment.
- Future maintenance or operating costs.
- Whether profits are sustainable over time.

Here are the most common questions about ROI, return on investment and how to evaluate investment performance.
What does ROI mean?
ROI stands for Return on Investment. It measures how much profit an investment generates compared with the amount spent.
How do you calculate ROI?
The standard formula is: ROI = (Net Profit ÷ Investment Cost) × 100. Net profit is revenue minus investment cost and additional expenses.
What is a good ROI?
A good ROI depends on the investment type, risk and time period. In many business cases, 20% or more can be considered healthy, while negative ROI means the investment lost money.

No. Profit is the money earned after costs. ROI is a percentage that compares profit with the original investment.
