Private vs Public College
Compare expected financial value using each school's net price, borrowing, completion probability, and likely starting salary.
Private college
Use net price after grants, not published sticker price.
Public college
Use comparable program and living-cost assumptions.
About the Private vs Public College
Choosing between a private and public college is rarely as simple as sticker price, because financial aid, expected completion rates, and post-graduation earnings can vary enough between two specific schools to reverse a decision based on tuition alone. This calculator compares each school's net price after aid, financing cost, completion probability, and expected starting salary to produce an expected financial value for each option, rather than comparing headline tuition figures. It's built for students and families who have real offers in hand — enter the actual net price, loan terms, and completion and salary expectations for the specific schools and programs being compared, not general institution-type averages.
How this calculator works
The exact model, assumptions, and limitations used for this decision.
Expected school value = starting salary × earnings horizon × completion probability − cash-paid net price − total amortized loan payments.
Calculation steps
- Each school's annual net price is multiplied by expected years.
- Loan principal is separated from cash-paid cost and amortized at the shared rate and term.
- Earnings are probability-adjusted using each school's entered completion rate.
Important assumptions
- Starting salary remains constant for a simple side-by-side horizon comparison.
- Programs, locations, and career outcomes are reasonably comparable.
- Need-based aid, loan terms, and completion probabilities are entered separately for each school.
Frequently asked questions
Common questions about inputs, assumptions, and interpreting the result.
01Should I compare sticker price?+
No. Use net price after grants and scholarships, plus required books, housing, transportation, and other attendance costs.
02Why include completion probability?+
Paying part of the cost without completing can produce debt without the modeled graduate earnings. Completion rates are imperfect but useful risk indicators.
03Does private college always produce higher earnings?+
No. Outcomes vary more by program, occupation, student background, location, and completion than by public or private label alone.
04How should merit aid be handled?+
Reduce net price only for aid you reasonably expect to retain. Stress-test loss of renewable aid if GPA or enrollment conditions apply.
05What if degree lengths differ?+
Enter each school's realistic years to completion. Additional years increase direct cost and delay earnings.
06What nonfinancial factors matter?+
Program quality, accreditation, support, transfer credits, network, campus fit, safety, and geographic access to employers can change the decision.
07How should I handle a private school's larger merit scholarship vs a public school's in-state discount?+
Enter each school's actual net price after all aid you expect to keep — the calculator doesn't care which type of discount produced the lower number, only the final net cost.
08What if I'm comparing an out-of-state public school to a private one?+
Use the out-of-state public tuition and fees as that school's net price input; out-of-state public pricing can sometimes be close to or higher than a private school's net price after aid.
