Frequently Asked Questions
Quick answers for busy business owners.
What is a good ROI?
It depends on risk: 5–10% is solid for low-risk options, while 20%+ is often expected for business projects. Always compare against your alternatives.
How is ROI calculated?
ROI = (Revenue − Cost) ÷ Cost × 100. It works for ads, equipment, courses — any investment with measurable returns.
What are ROI limitations?
ROI ignores time. A 50% ROI over 10 years is very different from 50% in 6 months — consider annualizing for fair comparisons.
