Quick Reference Table
| Category | Best ROI | Worst ROI |
|---|---|---|
| Education | Trade school, CS degree (state school) | Unfunded PhD, private liberal arts |
| Certifications | AWS, CDL, coding bootcamp | Expensive niche certs |
| Career change | Nursing, tech, trades | Teaching (financially) |
| Big decisions | Relocate to lower COL, start business (lean) | Franchise (high buy-in) |
The Bottom Line
The highest-ROI investments are usually the cheapest: trade certifications, in-demand tech certs, and state school degrees in employable fields. Expensive doesn’t mean better — a $200K private university degree and a $40K state school degree often lead to the same salary. Before making any major financial decision, calculate the break-even point and the 20-year ROI. If the numbers don’t work on paper, they probably won’t work in real life either.
