College ROI Calculator

Monte Carlo simulation showing the range of financial outcomes

Why College ROI Matters

College is one of the largest investments you'll ever make. A 4-year degree can cost anywhere from $0 to $300,000+ depending on the school and your family's income.

But unlike buying a house or investing in stocks, most families don't think about college in terms of return on investment. They should.

The uncomfortable truth:

Some $70k/year schools have worse ROI than $15k/year state schools
Your major matters more than your school for earnings
A 60% graduation rate means 40% of students pay without getting a degree
"Prestige" doesn't always translate to higher earnings

This calculator helps you see the range of outcomes, not just averages. Because your actual result could be anywhere in that distribution.

Real Examples: What ROI Looks Like

Elite Private (MIT)

Cost: $0/yr (if family income <$100k)

Median earnings: $143k

Typical ROI: +500% to +2000%

High earnings, generous aid = exceptional ROI for low/middle income families

State Flagship (UT Austin)

Cost: ~$12k/yr (in-state)

Median earnings: $65k

Typical ROI: +150% to +400%

Solid earnings, low cost = reliable positive ROI

Private Liberal Arts

Cost: ~$35k/yr (after aid)

Median earnings: $55k

Typical ROI: +50% to +200%

Higher cost, moderate earnings = positive but variable ROI

How Monte Carlo Simulation Works

Monte Carlo simulation runs thousands of scenarios to show you the full range of possible outcomes, not just one number.

Without Monte Carlo (Traditional)

Example: State University

Cost: $15,000/yr × 4 = $60,000
Median earnings: $55,000
Baseline (HS grad): $35,000
10-yr benefit: ($55k - $35k) × 10 = $200,000
ROI: ($200k - $60k) / $60k = +233%

Problem: Assumes everyone graduates in 4 years and earns the median. Reality is messier.

With Monte Carlo (This Calculator)

Same school, 10,000 simulations:

Some students earn $40k, others $80k
65% graduate (35% don't finish)
Grads take 4-6 years to finish
Non-grads pay 2 years, earn less

Results:

10th percentile: +50%
50th percentile: +180%
90th percentile: +350%

You see the real range of outcomes.

Simulation Walkthrough: Ohio State University

Real data: 10th=$25k, 25th=$38k, 50th=$55k, 75th=$72k, 90th=$95k, Grad rate=83%, Cost=$12k/yr (in-state)

Step 1: Sample Earnings

We randomly draw a percentile (0-100%) and interpolate between actual earnings data.

Simulation #1: Random 45% → between 25th ($38k) and 50th ($55k) → $49,000

Simulation #2: Random 18% → between 10th ($25k) and 25th ($38k) → $32,000

Simulation #3: Random 82% → between 75th ($72k) and 90th ($95k) → $83,000

Step 2: Determine Graduation

Roll a weighted coin: 83% chance of graduating, 17% chance of dropping out.

Simulation #1: Random 0.45 < 0.83 → Graduates

Simulation #2: Random 0.91 > 0.83 → Drops out (earns ~$38k, HS grad + some college)

Simulation #3: Random 0.22 < 0.83 → Graduates

Step 3: Years Enrolled

Graduates: 60% finish in 4 years, 25% in 5, 15% in 6. Dropouts: average 2 years.

Simulation #1: Graduate → 4 years → Cost: 4 × $12k = $48k

Simulation #2: Dropout → 2 years → Cost: 2 × $12k = $24k

Simulation #3: Graduate → 5 years → Cost: 5 × $12k = $60k

Step 4: Calculate ROI

ROI = ((Earnings - $35k baseline) × 10 years - Total Cost) / Total Cost × 100%

Simulation #1: (($49k - $35k) × 10 - $48k) / $48k = +192%

Simulation #2: (($38k - $35k) × 10 - $24k) / $24k = +25%

Simulation #3: (($83k - $35k) × 10 - $60k) / $60k = +700%

We run 10,000 simulations like this. The histogram shows how often each ROI occurs.

The $35,000 baseline is average earnings for someone with only a high school diploma. ROI measures how much better off you are compared to not going to college.

How to Interpret Your Results

+200%+

Excellent ROI. You're likely to earn back your investment 3x or more over 10 years. This is typical of high-earning fields (CS, engineering, finance) at schools with good aid.

+100-200%

Good ROI. Solid return comparable to long-term stock market performance. Most state schools and many private schools fall here.

+0-100%

Modest ROI. Still positive, but consider whether the non-financial benefits (network, experience) justify the cost vs. cheaper alternatives.

Negative

Negative ROI. You may earn less than you invested. This can happen with high-cost schools, low graduation rates, or low-earning fields. Consider alternatives carefully.
