Future Income: Score Guide
Future income predictor tests estimate earnings trajectories based on education, career stage, skills, and other factors. Scores typically fall into four tiers. This guide explains every range.
Score Bands at a Glance
| Lower quartile | Below median trajectory | Earnings likely below the population median for the relevant age and field. |
| Lower-middle | Modest growth | Trajectory below median but with growth potential. |
| Upper-middle | Above-median trajectory | Strong factors point to above-median lifetime earnings. |
| Upper quartile | High trajectory | Top-decile factors aligned. Strong long-run earnings expected. |
What the Research Says
Income trajectory research consistently identifies education, occupation, geography, network density, and Conscientiousness as the strongest predictors. Cognitive ability matters but less than is commonly assumed; it's typically dominated by occupational choice and persistence.
Most lifetime earnings differences are set by occupational choice, not within-occupation performance. Choosing the right field amplifies earnings far more than excelling within a low-paying field. Industry switches in mid-career produce the largest income changes.
Earnings predictions become more accurate as career stage advances. Mid-career predictions (15+ years in) achieve 0.6+ correlation with subsequent earnings; early-career predictions (within 5 years of entering work) are noisier (~0.3 correlation).

Frequently Asked Questions
How accurate are income predictions?
Mid-career predictions are reasonably accurate (r ≈ 0.6 with subsequent 10-year earnings). Early-career predictions are noisier.
What's the strongest income driver?
Occupational choice dominates. Within-occupation performance matters but is typically smaller than between-occupation differences.
Does education predict income?
Yes, moderately. The effect varies hugely by field — STEM and professional degrees produce stronger income effects than most liberal arts degrees.
Can I change my income trajectory?
Yes — career switches, skill acquisition, and geographic moves all produce measurable changes. Most large income changes happen at career transitions.
How does cognitive ability affect income?
Moderately, mostly indirectly through occupational selection. Within most occupations, additional cognitive ability has diminishing returns.
Is income happiness?
Above middle-class thresholds, weakly. The Easterlin paradox shows income increases produce diminishing happiness gains once basic needs are met.
Should I optimize for income?
Personal choice. Optimizing for income alone tends to produce burnout if not paired with values alignment. The most sustainable high earners typically also enjoy their work.
How does location affect income?
Substantially. Cost-of-living-adjusted income varies less by location than nominal income, but absolute earnings can vary 2–3x across countries and cities.
