College Cost Calculator

The published sticker price of a college is close to meaningless, and the gap between it and what families actually pay has widened for decades. Institutional grant aid, federal and state grants, and merit scholarships mean the average student at a private university pays substantially less than the advertised figure. The number that matters is net price — cost after gift aid — and every US institution is required to publish a net price calculator for exactly this reason.

The mistake that most distorts planning is treating the current year's cost as fixed. College costs have historically risen faster than general inflation, so multiplying today's price by four understates a four-year degree meaningfully. Compounding at four percent, the fourth year costs around twelve percent more than the first, and the total exceeds four times the current figure by a substantial margin.

Loan interest deserves particular attention because of when it starts. Subsidised federal loans do not accrue interest while you are enrolled, but unsubsidised loans and private loans do, and that interest capitalises into the principal at repayment. Money borrowed in the first year has been compounding for four years by graduation, which is why the balance owed on day one is noticeably larger than the sum of what was borrowed.

The most useful sanity check is the ratio of total debt to expected starting salary. The widely used guideline is that total borrowing should not exceed one year's starting pay, which keeps repayment on a standard ten-year plan at a manageable share of income. Beyond that ratio, payments start to crowd out saving, housing and everything else in the years when compounding would do the most good.
