If you carry both student loans and a credit card balance, pay the credit card first. The average card APR is about 21% versus roughly 6.4% on federal student loans, so each extra dollar on the card kills about three times more interest. But never stop paying your student loans: federal loans default after 270 days, triggering wage garnishment and tax-refund seizure. Keep loans on automatic minimums (or an income-driven plan) while you attack cards with the avalanche method. Here is the full reasoning.
Key Takeaways
- Pay credit cards first (about 21% vs 6.4%), so each dollar kills roughly 3x more interest.
- Never stop paying student loans; federal loans default after 270 days with severe consequences.
- Keep loans on automatic minimums (or income-driven repayment) while you attack the cards.
- Student loan interest is deductible up to $2,500; credit card interest is not.
What Is the Quick Answer?
For most borrowers, pay credit cards first. The average card APR is about 21% (Federal Reserve, 2026), while the federal undergraduate Direct Loan rate is 6.39% for 2025-2026 and 6.52% for loans disbursed from July 1, 2026. Credit cards cost more than three times as much in annual interest, so always pay the minimum on student loans while aggressively paying down cards. The only exception: if a specific debt (like a high-rate private student loan) charges more than your card, attack the higher rate first.
How Common Is the “Double Debt” Problem?
Very. The average federal student loan balance is about $39,547 per borrower (2025), with roughly $27,420 owed at graduation for public-university students. On the card side, the average college-student balance is around $2,100 (median much lower at about $860). Research by Pinto and Mansfield found a “double jeopardy” pattern: students most burdened by credit card debt also carried significantly more student loan debt (an average of about $11,067 vs $7,486 for financially stable peers), and the two were positively correlated. Trouble with one form of debt predicted trouble with the other.
What Does the Interest Math Show?
| Debt | Balance | Rate | Annual interest |
|---|---|---|---|
| Credit card | $5,000 | ~21% | ~$1,070 |
| Federal student loan | $5,000 | 6.39% | ~$320 |
Every extra dollar toward the card saves about 21 cents a year; toward the loan, about 6 cents. The tax angle widens the gap: student loan interest is deductible up to $2,500 a year (above the line, no itemizing needed), so at a 22% bracket, $2,000 of interest saves about $440, cutting the real cost of the loan. Credit card interest has no such benefit. See our guide on paying off credit card debt fast.

What Is the Rule You Cannot Break?
Always pay at least the minimum on student loans. Federal loans go delinquent after one missed payment and default after 270 days, which (unlike credit card default) triggers wage garnishment of up to 15% of disposable pay with no court order, full tax-refund seizure, Social Security offset, loss of future federal aid, and 7 years of credit damage. Credit card default is serious too, but no one can garnish wages or seize refunds without a court judgment. So make the student loan minimum automatically, and throw every extra dollar at the cards. See our guide on student loan default.
What Is the Step-by-Step Strategy?
- Automate student loan minimums. Set autopay at studentaid.gov (most servicers give a 0.25% rate cut for autopay), so you never miss one.
- Consider income-driven repayment. If the minimum eats too much cash, IBR (10% to 15% of discretionary income) or the new RAP plan (launched July 1, 2026, at 1% to 10% of AGI with a $10 monthly minimum) can lower it, freeing cash for the cards. The SAVE plan was vacated by a court in early 2026; see student loan changes in 2026.
- Attack cards with the avalanche. Pay minimums on all, then put extra on the highest-rate card, then roll to the next. See our guide on avalanche vs snowball.
- Use a 0% balance transfer to pause interest while you pay down the card principal.
- Then redirect to student loans. Once the cards are gone, send the full payment to the highest-rate loan (often a private loan).

What Situations Change the Math?
High-rate private loans: private loans can run 10% to 14%+, so if one tops your card rate, it becomes the priority; rank all debts by rate regardless of type. Very small card balances: clearing a $500 card first for the organizational and psychological win can beat strict rate ordering. PSLF or forgiveness: if you are on a forgiveness path, paying down federal principal reduces what gets forgiven, so make minimum income-driven payments and use extra cash on cards or savings instead.
FAQ
Should I pay off student loans or credit cards first?
Credit cards, in most cases. At about 21% versus 6.39%, card debt costs more than three times as much per dollar. Keep paying the student loan minimum to avoid default while you attack the cards.
What happens if I stop paying student loans?
Never stop. Federal loans default after 270 days, triggering wage garnishment, tax-refund seizure, and loss of future aid, all without a court order. Pay the minimum automatically while focusing extra cash on cards.
Can income-driven repayment help me pay off cards faster?
Yes. IBR or the new RAP plan can lower your monthly student loan payment, freeing cash to kill high-rate card debt. It extends your loan timeline, but the rate gap usually makes it worthwhile.
Is student loan interest tax-deductible?
Yes, up to $2,500 a year, above the line, even if you do not itemize (it phases out at higher incomes). Credit card interest is not deductible, which further supports paying cards first.
Bottom Line
With cards near 21% and federal student loans near 6.4%, pay the credit cards first while keeping student loans on automatic minimums, since federal default is far more dangerous than card default. Use income-driven repayment to free up cash if needed, attack cards with the avalanche, then redirect to loans.
