Key Takeaways
The 1× rule: Borrowing less than your expected starting salary is considered safe by most financial advisors. Most bachelor's degrees meet this threshold.
IDR is the safety net: Borrowers with debt-to-salary ratios above 1× are prime candidates for income-driven repayment plans. PSLF is especially powerful for social workers, teachers, and government employees.
Grad debt compounds quickly: Professional degrees (MD, JD, DDS) carry very high debt loads. Even with high salaries, residents and new attorneys often need IDR plans to manage payments during early career years.
