Side-by-Side Comparison
Break-Even Analysis

How much of your payments go to interest over the life of each loan?

Federal vs. Private Loans

Federal loans offer income-driven repayment, deferment, forbearance, and forgiveness options. Private loans may have lower rates but lack these protections.

Refinancing Risk

Refinancing federal loans into private loans permanently forfeits IDR, PSLF, and federal protections. Compare carefully before refinancing.

Capitalized Interest

Interest that accrues during school or deferment gets capitalized (added to principal) when repayment begins, increasing your effective balance.

Break-Even Point

The month when a lower monthly payment loan has saved you enough cash vs. a higher-payment loan to offset its higher total cost.
