There is a widely used rule of thumb, and it is unusually good for a rule of thumb: total student debt at graduation should not exceed your expected first year salary.
The logic is that it keeps payments on a standard ten year plan to roughly 8% to 10% of gross income, which is manageable alongside rent and everything else.
How to actually use it
- Find a realistic median starting salary for your intended field, not the top of the range and not the university's marketing figure. Government labour statistics are more honest than most sources.
- Total everything you will borrow across all years, not just year one. This is the step people skip, and it is where the number quietly triples.
- Compare. If total borrowing exceeds that salary, something needs to change.
Multiply year one by four. A first-year loan of $12,000 feels modest. Across four years, with rising costs, that is closer to $50,000 plus accrued interest on the unsubsidised portion. Always run the four year total before signing year one.
What to do when the number is too high
- Appeal the aid offer. Costs nothing and works more often than people expect.
- Compare net price, not sticker price. A more expensive school with better aid can be cheaper than a cheaper school with none.
- Consider two years at community college then transferring. The degree is issued by the institution that grants it.
- Reconsider the field-to-cost match. Borrowing $90,000 for a field paying $40,000 is a decade-long problem regardless of how much you love the subject.
The caveat worth stating
This rule is about affordability, not worth. Some careers require credentials that cost more than the first year pays, and income-driven repayment exists precisely for those cases. The rule is a signal to plan differently, not a verdict on your choices.
The short version
- Keep total borrowing at or below your expected first year salary.
- Total all four years before signing for year one.
- Use realistic median salary data, not university marketing.
- Appeal the aid offer and compare net prices before borrowing more.
Common questions
What is a reasonable amount of student loan debt?
A common benchmark is total borrowing no greater than your expected first-year salary, which keeps standard repayment near 8% to 10% of gross income.
How do I estimate my starting salary?
Use government labour statistics for your field and region rather than university-published figures, which often reflect the highest earners or small samples.
What if I have already borrowed too much?
Income-driven repayment caps payments as a share of your income, and forgiveness programs exist for public service. Talk to your servicer before missing a payment.
