Methodology
Every school gets a score from 0 to 100 based on five measurable factors. No reputation. No opinions. Here's exactly how it works.
How the ROI Score Works
We analyze 1,665 four-year degree-granting institutions using data from the U.S. Department of Education's College Scorecard. Each school is scored on five financial outcome metrics. Scores are calculated using percentile-based normalization - meaning each school is ranked against all other schools in the dataset, not against arbitrary thresholds.
Percentile-based scoring means a score of 80 on a given metric means that school performs better than 80% of all schools on that metric. This approach is resistant to outliers and provides meaningful relative comparisons.
Score Components & Weights
Final Score = (Earnings Premium x 0.30) + (Payback Period x 0.25) + (Debt-to-Earnings x 0.20) + (Completion Rate x 0.15) + (Repayment x 0.10)
1. Earnings Premium
How much more do graduates earn compared to what they paid? We calculate the ratio of the annual earnings premium (median earnings 10 years after entry minus median high school graduate earnings of $35,000) to the total net cost of attendance over four years.
(Median 10yr Earnings - $35,000) / (Net Price x 4)A higher ratio means graduates earn significantly more relative to what they paid. A ratio above 1.0 means the annual earnings premium exceeds the total cost of a single year - a strong signal.
This is the core ROI question: does the earnings boost justify the price tag? Schools that produce high earners at a reasonable cost score well here.
2. Payback Period
How many years until the investment breaks even? We calculate total investment (4 years of tuition plus 4 years of forgone earnings at $35,000/year) divided by the annual earnings premium.
(Net Price x 4 + $35,000 x 4) / (Median 10yr Earnings - $35,000)Lower is better. A payback period under 5 years is excellent. Over 15 years starts to look questionable. We invert this metric so that shorter payback periods produce higher scores.
This captures opportunity cost - the money you could have earned by working instead of attending college. Some expensive schools with modest graduate earnings have payback periods exceeding 20 years.
3. Debt-to-Earnings Ratio
How manageable is the debt relative to what graduates earn? We divide median debt at graduation by median earnings 6 years after entry.
Median Debt at Graduation / Median Earnings (6yr)Financial advisors recommend total student debt should not exceed your first year's salary (ratio of 1.0 or less). Ratios below 0.5 are excellent. Above 1.5 is a serious warning sign.
Even if a school produces decent earners, excessive debt can undermine the financial benefit for years or decades after graduation.
4. Completion Rate
What percentage of students actually graduate within 6 years? If you don't complete your degree, the ROI is almost certainly negative - you have the debt and opportunity cost but not the credential.
6-Year Completion RateHigher is better. Top schools complete 90%+ of students. The national average for 4-year institutions hovers around 60%. Schools below 40% mean most students who enroll don't finish.
This is the risk factor. A school might have great earnings data for graduates, but if only 30% of students graduate, the other 70% likely have debt without the degree.
5. Loan Repayment Success
Are graduates successfully paying back their federal loans? We use the 3-year repayment rate for borrowers who completed their degree.
3-Year Repayment Rate (Completers)Higher is better. This measures the share of borrowers who are making progress on their loan principal (not just making payments, but actually reducing their balance).
Repayment rates capture something earnings alone miss. A school where graduates earn $50K but can't make loan payments signals hidden problems - high cost of living in the area, unstable employment, or debt loads that overwhelm even decent salaries.
Percentile Normalization
Raw metrics (like earnings or completion rates) are converted to percentile scores before weighting. Here's why:
- 1Different metrics use different scales (dollars vs. percentages vs. ratios). Percentiles put everything on the same 0-100 scale.
- 2Outliers don't distort the scores. A school with $200K median earnings doesn't warp the scale for everyone else.
- 3The scores reflect relative standing. A score of 75 means "better than 75% of schools" - intuitive and comparable across metrics.
For "lower is better" metrics (payback period, debt-to-earnings ratio), we invert the percentile so that a shorter payback or lower debt ratio produces a higher score.
Missing Data Handling
Not every school reports every data point. Here's how we handle gaps:
Excluded if missing:
Net price, 10-year median earnings, completion rate, or enrollment. Without these core metrics, a meaningful ROI score is impossible.
Median-imputed if missing:
Median debt, repayment rates. Schools missing these non-critical fields receive the median score (50th percentile) for that component, and their profile shows a data completeness indicator so you know which numbers are real and which are estimated.
Score Tiers
Exceptional Value
Top-tier financial outcomes. Graduates earn well above average relative to cost, debt is manageable, and completion rates are high.
Strong Value
Above-average returns on investment. These schools deliver solid financial outcomes for most graduates.
Fair Value
Average financial returns. The investment may pay off, but the margins are thinner and more dependent on major choice and individual outcomes.
Below Average
Below-average financial returns. Graduates may struggle with debt relative to earnings. Major selection becomes critical.
Poor Value
Weak financial outcomes. High debt relative to earnings, low completion rates, or poor repayment success. Careful consideration recommended.
As of the current dataset: 83 schools score Exceptional, 218 Strong, 335 Fair, 322 Below Average, and 707 Poor. Only 18% of schools score 75 or above.
Important Caveats
- Earnings data reflects students who entered college roughly 10 years ago. Programs, faculty, and job markets change.
- Scores reflect median outcomes. Individual results depend heavily on major choice, effort, and career decisions.
- Net price varies by family income. The average net price we use may not reflect what your family would actually pay.
- ROI is one dimension of value. Personal growth, intellectual development, and life satisfaction matter - they just can't be quantified here.
- For-profit and very small institutions may have less reliable data due to smaller sample sizes.
