Tech Career ROI Comparison: CS Degree vs Bootcamp vs Self-Taught

3 minute read

Long read

Three main paths lead to tech careers: CS degrees, coding bootcamps, and self-taught portfolios. Each has different costs, timelines, and salary outcomes. Comparing them on net ROI helps prospective tech workers choose the right entry point.

How each tech career path compares on cost and earnings

Salary Overview

CS degree holders start at higher salaries ($90,000–$130,000 at FAANG) and have the highest long-term ceiling. Bootcamp graduates enter faster at $65,000–$95,000. Self-taught developers face the longest job search but zero training cost.

By year 5–7, salary differences between paths narrow significantly. At the senior level, skills and track record matter far more than educational credentials in most tech hiring.

Return on Investment Analysis

State-school CS delivers the best overall ROI: moderate cost ($40,000–$80,000 in-state) with strong starting salaries and access to FAANG new-grad pipelines. Private CS ROI depends heavily on school tier and scholarship coverage.

Bootcamps offer the fastest ROI from training start to income: 3–6 months of training followed by $65,000–$95,000 jobs. Self-taught paths have the highest theoretical ROI (zero cost) but the longest and most uncertain job search.

Factors That Affect Earnings

Training cost — CS degrees cost 5–20x more than bootcamps
Time to income — bootcamps enter the market 2–3 years faster than CS
Starting salary — CS degrees command 15–30% more at entry
Ceiling — all paths converge at senior level, but CS opens research/ML roles
Network effects — CS programs and top bootcamps provide alumni networks

Career Growth Timeline

CS degree: 4 years training → $90K–$130K start → $200K–$400K+ TC at senior
Bootcamp: 3–6 months → $65K–$95K start → $150K–$300K TC at senior
Self-taught: 6–18 months → $50K–$80K start → $120K–$250K TC at senior
All paths: convergence at staff/principal level, $300K–$600K+ TC

Geographic and Industry Variation

SF, Seattle, and NYC amplify the salary premium for all three paths. Remote work has made geographic arbitrage easier — living in a low-cost area while earning big-tech pay — for experienced developers regardless of educational path.

In mid-tier markets, the CS degree premium at entry narrows significantly. Local bootcamp and self-taught developers compete effectively with CS grads at small-to-mid-size companies.

Key Takeaways

CS degree: highest start and ceiling, but most expensive
Bootcamp: fastest ROI from start to first paycheck
All paths converge at senior level — skills trump credentials

Conclusion

There is no single best path into tech — it depends on budget, timeline, and career ambition. CS degrees offer the highest ceiling, bootcamps the fastest entry, and self-taught paths the lowest cost. All lead to the same senior roles eventually.
