Frequently Asked Questions
What is a good ROI percentage?
A good ROI typically depends on your industry and risk tolerance. Generally, an ROI of 15-30% is considered good for most investments. However, some industries may accept lower returns while others require higher returns to offset greater risks.
How long should I wait before evaluating ROI?
The evaluation period depends on your investment type. Short-term investments might be evaluated monthly or quarterly, while long-term investments should be assessed over years to account for market cycles and growth patterns.
