Avalanche vs. Snowball for Student Loans

Just like with credit cards, you can attack student loans using two main methods:

  • Avalanche Method: Focus on the loan with the highest interest rate (usually private loans or PLUS loans). This saves you the most money.
  • Snowball Method: Focus on the smallest individual loan balance. This clears accounts faster and builds psychological momentum.

Use the calculator above to see how extra payments impact your debt-free date.

The PSLF Warning

Do NOT refinance federal student loans if you work in public service, education, non-profit, or government roles.

Public Service Loan Forgiveness (PSLF) forgives your remaining balance tax-free after 120 qualifying payments.

Refinancing federal loans into a private loan means you lose access to PSLF, Income-Driven Repayment (IDR), and federal deferment forever.

Refinancing: Pros & Cons

Frequently Asked Questions

Should I pay off student loans or invest?

It depends on the interest rate. If your loan rate is above 6%, paying it off represents a guaranteed 6% return, which is very safe. If your rate is low (e.g., 3-4%), investing in the S&P 500 might yield higher returns (averaging 7-10%) over the long term. Always get your employer 401(k) match first.

Does paying off student loans boost my credit score?

It can improve your Debt-to-Income (DTI) ratio, which helps you qualify for a mortgage. However, closing an old installment loan might cause a temporary dip in your score due to a change in "credit mix" or "average age of accounts." This is usually minor and temporary compared to the financial freedom of being debt-free.

Can I pay off specific loan groups first?

Yes. Contact your loan servicer and instruct them to apply your extra payments specifically to the loan group with the highest interest rate (Avalanche) or lowest balance (Snowball). By default, they may spread it across all groups, which is less efficient.

Is student loan interest tax deductible?

Yes, you can typically deduct up to $2,500 in student loan interest per year from your taxable income, depending on your modified adjusted gross income (MAGI). You do not need to itemize deductions to claim this.

Should I refinance to a variable or fixed rate?

In a high-interest environment, fixed rates are safer because your payment never changes. Variable rates often start lower but can skyrocket if the Fed raises rates. For most borrowers, a Fixed Rate is the recommended choice for long-term stability.
