What is a good ROI percentage?

A 'good' ROI depends on the industry and context. Generally, an ROI above 10-15% is considered solid for most business investments, but high-growth startups or marketing campaigns often target 100% or more.

Does ROI account for time?

No. Standard ROI does not factor in how long the investment takes to generate returns. For time-adjusted analysis, use metrics like NPV or annualised ROI.

Can I use ROI to compare different types of investments?

Yes. Because ROI is expressed as a percentage, it provides a common scale for comparing investments of different sizes and types, such as comparing a marketing spend to a capital equipment purchase.

Understanding the ROI Formula

The standard ROI formula is: ROI = ((Net Profit) / Cost of Investment) x 100. Net Profit equals the total revenue generated minus the total cost of the investment. A positive ROI means the investment earned more than it cost, while a negative ROI indicates a loss. For example, if you spent $5,000 on a marketing campaign and generated $8,000 in revenue, your net profit is $3,000 and your ROI is 60%.

When to Use ROI

Evaluating whether to invest in new equipment or software
Measuring the effectiveness of employee training programs
Deciding between competing project proposals
Reporting performance to stakeholders and investors

Limitations of ROI

While ROI is a powerful metric, it does not account for the time value of money. An investment that returns 50% in one year is far more attractive than one that returns 50% over five years. For time-sensitive comparisons, consider using Net Present Value (NPV) or Internal Rate of Return (IRR) alongside ROI to get a fuller picture of profitability.
