Debt Management: Good Debt vs. Bad Debt

Not all debt is created equal. A mortgage at 4% that builds equity in an appreciating asset is fundamentally different from credit card debt at 22% on depreciating purchases. Understanding this distinction is essential for financial decision-making.

Federal student loan repayment options

Federal student loans — repayment options comparison

Federal student loans offer repayment paths that private loans do not — and the menu changed structurally on July 1, 2026. A 2025 federal law replaced the old income-driven lineup: the SAVE plan has ended, and a single income-based option called the Repayment Assistance Plan (RAP) launched for Direct Loans. Which paths you can use now depends mainly on WHEN your first federal loan was taken out — the decision guide below walks through it. Details are still being implemented; verify your own options at studentaid.gov/manage-loans/repayment/plans before choosing.

Comparing federal repayment plans (as of July 2026)

PlanMonthly PaymentForgivenessInterest Behavior
StandardFixed amortized payment (highest monthly amount; term now scales with balance for new borrowers)No forgiveness path — fully repaid at end of termAccrues normally; you pay the least total interest of any path
RAP (new, from 2026-07-01)1–10% of your adjusted gross income by income bracket, minus $50 per dependent child; $10/month minimumBalance forgiven after 30 years (360 qualifying payments); counts toward PSLFUnpaid interest is waived each month — your balance never grows while you pay as agreed; small principal subsidy when the payment doesn’t cover it
IBR (existing borrowers only)10% of discretionary income (first loan on/after 2014-07-01) or 15% (before 2014-07-01)Forgiveness after 20 years (post-2014 borrowers) or 25 years (pre-2014); forgiven amount may be federally taxable again from 2026 — the prior exclusion expired; verify current IRS guidanceInterest accrues normally; not open to borrowers whose first loan is on/after 2026-07-01
PSLF (Public Service)Same as your qualifying plan (IBR or RAP) while working full-time for a qualifying employerRemaining balance forgiven after 10 years (120 qualifying payments); PSLF forgiveness is tax-freeInterest accrues normally; only Direct Loans qualify — FFEL loans must be consolidated first
Deferment / ForbearancePayments paused temporarilyNo forgiveness path — the clock stops; balance may growSubsidized loans: government may pay interest during deferment. Unsubsidized loans and forbearance: interest accrues and capitalizes — your balance grows while payments pause

Which repayment path applies to you? A decision guide

Start with one question: when was your FIRST federal student loan taken out? That single date decides most of the menu below. Step through the branches — each Continue reveals the next situation.

Choosing a repayment plan by loan date

You have exactly two choices: the Standard plan or RAP. There is no other income-driven option. Rule of thumb: if the Standard payment fits your budget, it costs the least in total interest; if it doesn’t, RAP scales the payment to your income (1–10% of AGI, $10/month minimum) and waives unpaid interest so the balance never grows.

Those plans are being retired. You must move to IBR or RAP by July 1, 2028 — and if you do nothing, you will be moved automatically without choosing. Compare your IBR payment (10% or 15% of discretionary income, forgiveness at 20–25 years — including your years already banked) against RAP (AGI-based, 30-year clock) before the deadline; for many borrowers close to IBR forgiveness, switching restarts nothing but RAP’s longer clock still matters.

You can stay. IBR keeps its terms for existing borrowers (10%/20-year if your first loan was on/after July 1, 2014; 15%/25-year if earlier). Staying put is often right — but run the numbers once at studentaid.gov’s Loan Simulator, because RAP’s interest waiver can beat IBR when your payment doesn’t cover monthly interest.

Layer PSLF on top: 120 qualifying payments (10 years) while employed full-time by government or an eligible nonprofit forgives the rest, tax-free. Both IBR and RAP count. Certify your employment yearly — the #1 PSLF failure is paperwork, not eligibility.

Why paying off high-interest debt is a risk-free return

Paying off a credit card at 22% interest is a risk-free cost reduction equivalent to a 22% pre-tax return — the highest such reduction available in personal finance. Pay off high-interest debt before investing (except for employer 401(k) match). One honest caveat: the math is only risk-free if your behavior cooperates — the guaranteed 22% assumes you do not re-borrow on the card you just paid off, and that the payoff is not draining the emergency fund you would need for the next surprise expense (which would push you right back onto the card at 22%).

Avalanche versus snowball payoff strategies

Payoff StrategyHow It WorksBest For
Avalanche (highest rate first)Pay minimums on all, extra $ to highest-rate debtMathematically optimal — saves the most money
Snowball (smallest balance first)Pay minimums on all, extra $ to smallest balancePsychologically motivating — quick wins build momentum

The avalanche method saves more money, but the snowball method has higher completion rates because early wins maintain motivation. Choose the one you’ll actually stick with.

List your debts by interest rate

List all your debts with their interest rates. Any debt above 8% should be paid off before investing in the stock market (expected 10% return minus taxes and fees ≈ 7–8% net).

Whether to invest or pay off a high-rate card first

You have $5,000 in savings, a $3,000 credit card balance at 22%, and want to start investing. What should you do first?
Check your understanding

Sit with the ideas.

A new graduate has $30K student loans at 5%, $8K credit card debt at 21%, and a $60K salary with a 100% 401(k) match up to 3%. With $500/month extra, what's the optimal allocation?
