Methodology

How the Engines Work

The college value engine estimates total net cost, planned borrowing, monthly loan payment, total repayment, interest paid, expected earnings, debt-to-income ratio, payment-to-income ratio, break-even timing, sensitivity checks, and risk flags.

The public-vs-private engine compares two schools over 20 years. It combines net cost, non-tuition costs, borrowing, repayment, interest, expected earnings, and estimated net wealth to show the stronger financial outcome.

The student-loan-by-major engine estimates how much borrowing a major can reasonably support using expected starting salary, monthly payment, take-home pay, and the shown debt and payment safety rules.

The borrowing rules are intentionally visible: green debt is 60% of expected starting salary or less, yellow is 60-90%, orange is 90-125%, and red is above 125%. Monthly payment safety is green at 8% of gross monthly income or less, yellow at 8-10%, and red above 10%.

The engines show the entered assumptions, the key ratios, the risk flags, and the specific inputs most likely to change the result. That keeps the estimate tied to numbers a user can check.

This methodology is intentionally transparent. It is built for planning clarity, not financial, legal, tax, admissions, student loan, educational, or professional advice.
