Student loans are different from credit card debt in two important ways: they typically carry lower interest rates, and they often come with income-driven repayment options that can extend, rather than eliminate, the debt over longer periods. Paying off student loans faster requires treating them as the financial obligation they are, sequencing them correctly relative to your other debts, and avoiding the minimum-payment trap that the standard repayment plan encourages.
FreeByDate handles student loans in the same framework as any other debt, your real surplus, sequenced intelligently. If your student loans carry higher rates than your credit cards (less common but possible with private loans), they may sit earlier in the sequence. If they carry lower rates, they likely come last. FreeByDate calculates this for your specific portfolio.

Student loans vs credit cards, which to pay first?
The answer is almost always credit cards first. A credit card at 22% APR costs more than three times as much per dollar as a federal student loan at 6.5%. Paying down the student loan while carrying a high-rate credit card balance is mathematically equivalent to borrowing at 22% to invest at 6.5%, a guaranteed loss.
The exception is private student loans at high rates. If you carry a private loan at 13% and a credit card at 10.99%, the private loan sits earlier in the avalanche sequence regardless of type. Rate, not loan category, determines sequence position.
The extra payment rule, principal designation matters
One of the most common mistakes in student loan repayment is making extra payments without specifying principal application. Many loan servicers, when receiving a payment above the minimum, apply the excess to your next scheduled payment rather than to principal. This means your next month's required payment drops, but your principal balance barely changes.
To ensure extra payments reduce your principal: log into your servicer account and specify principal-only for the excess amount. Do this in writing if possible, or verify on your next statement that the balance decreased by more than the interest portion of your payment. This single step can shorten your repayment term by years on a large loan balance.
Refinancing student loans, when it helps and when it does not
Refinancing federal student loans into a private loan at a lower rate can save significant interest, but it permanently forfeits all federal protections: income-driven repayment, deferment, forbearance, and any forgiveness programs including PSLF.
If you are certain you will not need these protections and are not pursuing forgiveness, refinancing a 7% federal loan to a 5.5% private loan reduces interest by approximately $300 per year per $20,000 in balance. On a $40,000 balance, that is $600 per year, meaningful, but modest compared to the impact of a sequenced surplus concentration plan.
If you work in public service or a non-profit and may qualify for PSLF, do not refinance under any circumstances. The forgiveness value far exceeds any interest rate savings from refinancing.
