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.

Net price means cost of attendance less grants and scholarships. Family contributions, work-study earnings and employer funding pay that price; they do not lower it. Work-study earnings are assumed, not guaranteed. The calculation details separate the program price, these funding sources, loans and any remaining funding need. This follows the Federal Student Aid net-price definition.

The value model subtracts the program price and loan interest from added earnings. It counts loan principal once, as part of that price. College Worth Comprehensive also subtracts entered lost wages and forgone investment growth on the cost paid without loans. The two-school comparison uses its stated opportunity-return assumption. Changing family funding without changing price or loans changes the funding gap, not the economic cost.

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.
