What Is a Good ROI (Return on Investment)?

For long-term stock-market investing, an average annual return of about 7–10% (after inflation, roughly 7%) is widely considered good. For a one-off project, a positive ROI that beats safer alternatives is the benchmark. 'Good' always depends on the risk taken and the time involved.
