UPDATES LIVEAdding just $100/mo extra to a $37,850 loan at 6.53% saves $3,600 in interest and cuts 2.4 years off repayment
The faster you pay off student loans, the less interest you pay. Even small extra payments create massive savings because they reduce the principal that accrues daily interest.

Things to Know
Essential concepts for understanding your results
Interest ImpactHow does interest affect your debt payoff?
Interest is the invisible cost multiplier on debt. On $10,000 at 22% APR with minimum payments: you pay approximately $13,000 in interest — more than the original balance. Every dollar of extra payment goes directly to principal, reducing the balance that generates future interest. Even $50/month extra dramatically shortens the timeline and reduces total cost. The earlier in the loan you make extra payments, the greater the lifetime interest savings.
Strategy SelectionHow do you choose the right payoff strategy?
Two proven methods: Avalanche (target highest interest rate first) saves the most money — best when rate differences exceed 5%. Snowball (target smallest balance first) provides fastest motivational wins — best when you need psychological momentum. A hybrid approach (snowball 1-2 small debts for quick wins, then switch to avalanche) captures benefits of both. Either is dramatically better than minimum payments.
Financial FreedomWhat should you do after paying off debt?
Redirect 100% of former debt payments to wealth building: emergency fund (3-6 months expenses), then employer 401(k) match, then Roth IRA ($7,000/year), then max 401(k). The discipline that eliminated debt now builds wealth exponentially. A family freeing up $1,200/month from debt and investing it at 8% accumulates $445,000 in 15 years. Debt freedom is not the finish line — it is the launchpad.
Understanding Student Loan Repayment Options
Federal student loans offer several repayment plans beyond the standard 10-year plan. The Standard Plan has fixed payments over 10 years — the fastest payoff with the least interest. Income-Driven Repayment (IDR) plans cap payments at 10-20% of discretionary income and forgive remaining balances after 20-25 years. The newest plan, SAVE (Saving on a Valuable Education), caps undergraduate payments at 5% of discretionary income with a lower income threshold — making it the most affordable option for many borrowers.
The trade-off is clear: lower monthly payments mean more total interest. A $35,000 loan at 5.5% costs $380/month on the standard plan and $18,000 in total interest. On an IDR plan with $250/month payments, total interest could exceed $30,000 before any forgiveness applies. The optimal strategy depends on whether you qualify for Public Service Loan Forgiveness (PSLF) — if so, IDR with minimum payments makes sense because the balance is forgiven tax-free after 10 years of qualifying payments.

The $100/Month Rule: How Extra Payments Transform Your Timeline
Adding just $100/month to student loan payments has an outsized impact. On a $35,000 loan at 5.5%, the standard payment is $380/month over 10 years with $10,600 in total interest. Adding $100/month ($480 total) reduces payoff to 7 years 4 months and saves $3,200 in interest. Adding $200/month saves $5,400 and cuts the timeline to 6 years. The math is powerful because every extra dollar goes directly to principal, reducing the base that generates interest.
The best strategy for most borrowers: pay the minimum on all loans, then throw every extra dollar at the highest-interest loan (avalanche method). Once that loan is paid off, roll its payment into the next highest rate. This mathematically minimizes total interest paid. If motivation is your challenge, the snowball method (smallest balance first) gets you quick wins that maintain momentum.

Should You Refinance Federal Student Loans?
Refinancing to a private lender can lower your rate but permanently removes federal protections: income-driven repayment, PSLF eligibility, deferment, forbearance, and forgiveness. Only refinance if your income is stable and high, your credit qualifies for a rate at least 1% lower, and you have no plans for government or nonprofit work. If any condition isn't met, keep federal loans federal.
Snowball vs Avalanche for Student Loans
With multiple loans, the avalanche method (highest rate first) saves the most money. The snowball method (smallest balance first) provides faster psychological wins. Harvard Business Review research found snowball leads to faster total payoff because the wins keep people motivated. The interest difference is typically $500-2,000 on $40-60K — meaningful but secondary to commitment.
