ROI
ROI, or Return on Investment, is a metric that compares the financial return generated by an investment with its cost. It helps determine whether an initiative produced a profit, caused a loss, or simply recovered the money invested.
ROI can be used to evaluate a marketing campaign, website project, software implementation, process automation, equipment purchase, or product launch. The result is usually expressed as a percentage.
How do you calculate ROI?
The basic ROI formula is:
ROI = (value generated by the investment – cost of the investment) / cost of the investment × 100%
If a company invests $20,000 and the resulting financial value is $26,000, its ROI can be calculated as follows:
ROI = ($26,000 – $20,000) / $20,000 × 100% = 30%
This means the investment recovered its cost and generated an additional $0.30 in profit for every dollar invested.
How should ROI be interpreted?
- ROI above 0% means the value generated exceeded the cost of the investment;
- ROI of 0% means the investment recovered its cost without producing an additional profit;
- negative ROI means the return did not cover all included costs;
- ROI of 100% means the profit was equal to the original investment.
The result depends on which costs and benefits are included. Two companies may therefore calculate ROI differently for similar projects.
What is the difference between ROI and ROAS?
ROAS compares revenue attributed to advertising with ad spend. ROI has a broader scope and should consider actual profit and all relevant investment costs.
When calculating the ROI of a marketing campaign, a company may include ad spend, creative production, campaign management, software, product costs, shipping, discounts, and returns. A high ROAS does not therefore guarantee an equally high ROI.
Which costs should be included?
The scope of the calculation should match the purpose of the analysis. Depending on the investment, relevant costs may include:
- advertising spend;
- design and content production;
- agency or employee fees;
- software purchase and maintenance;
- system implementation and integration;
- product and order fulfillment costs;
- training, support, and ongoing management.
Benefits may include additional profit, lower operating costs, time savings, or increased productivity when these outcomes can be assigned a reliable financial value.
What is a good ROI?
There is no single ROI target suitable for every investment. An acceptable result depends on the time required to generate the return, the level of risk, financing costs, and the returns available from alternative uses of the money.
Investments should be compared over the same period and using consistent calculation rules. A 30% ROI achieved in three months is not equivalent to the same result generated over five years.
What are the limitations of ROI?
Basic ROI does not automatically account for time, risk, or changes in the value of money. It may also be difficult to determine how much of the result was genuinely caused by a specific investment.
In marketing, sales may be influenced by advertising, brand awareness, SEO, referrals, and previous customer interactions at the same time. ROI should therefore support business decisions rather than serve as the only measure of success.
