What is the difference between federal and private student loans?

Federal loans offer statutory protections: IDR plans, deferment rights, forgiveness programs, and default resolution options. Private loans are contractual products with lender-specific terms and generally none of these protections. Never refinance federal loans into private unless you have stable high income, no interest in forgiveness programs, and a meaningfully lower rate — refinancing is irreversible.

What is interest capitalization and how does it affect my balance?

Capitalization is when accumulated unpaid interest is added to your principal. Future interest then accrues on the larger balance. It happens when you exit deferment, enter repayment, change plans, or after forbearance ends. To limit capitalization, make interest payments during in-school periods or deferment if your budget allows.

Can my student loan payments be $0 per month?

Yes, on IDR plans, if your income is at or below a threshold (150–225% of the federal poverty line depending on the plan), your calculated payment is $0. $0 payments count toward IDR and PSLF forgiveness timelines. You must recertify income annually — failure to recertify can cause payments to jump to the full standard amount.

What happens if I default on a federal student loan?

After 270 days without payment: entire balance due immediately; tax refunds seized; wages garnished up to 15% without a court order; default reported to credit bureaus; ineligibility for additional federal aid. The Fresh Start program and loan rehabilitation can resolve default, but the damage is significant. Contact your servicer before defaulting — IDR plans can prevent it entirely.

Should I refinance my student loans?

For private loans, refinancing for a lower rate is often smart. For federal loans, refinancing permanently converts them to private and forfeits IDR, PSLF, deferment, and all federal protections. If you're in public service, work for a nonprofit, or anticipate lower income periods, refinancing federal loans is rarely the right choice. Model your projected forgiveness before deciding.

Understand My Student Loan Agreement — Promissory Note and Repayment Terms Explained

Most students sign their federal student loan promissory note online in minutes, committing to tens of thousands of dollars in debt without reading a word. The terms governing that debt — how interest capitalizes, what repayment options are available, how deferment and forbearance affect your balance, and what happens if you default — have enormous long-term consequences. Whether you have federal loans, private loans, or both, PlainDoc's free student loan explainer breaks down your promissory note in plain English so you can make informed decisions about repayment, forgiveness eligibility, and refinancing.

Federal vs. Private Student Loans: Fundamentally Different Contracts

The distinction between federal and private student loans is the most important thing to understand. Federal loans (Direct Subsidized, Direct Unsubsidized, PLUS, and Grad PLUS) come with statutory rights private loans don't offer: income-driven repayment (IDR) plans that cap payments as a percentage of income, Public Service Loan Forgiveness (PSLF), deferment and forbearance rights, and the ability to consolidate into federal programs. Private student loans are governed by individual lender contracts and generally offer none of these protections — they behave more like personal loans. Before doing anything with student loans — especially refinancing — determine whether you have federal loans, private loans, or both.

Interest Rates, Subsidies, and How Your Balance Grows

Federal loan interest rates are set by Congress each academic year and fixed for the life of the loan. Subsidized loans have a key benefit: the government pays your interest while you're enrolled at least half-time, during the grace period, and during deferment. Unsubsidized loans accrue interest from disbursement — even while you're in school. Private loan rates may be fixed or variable; variable rates can increase significantly over a long repayment period. Interest capitalization is critical: when accrued interest is added to your principal balance (which occurs when you enter repayment, switch plans, or exit deferment), you then pay interest on the new, larger balance — accelerating the total cost of the debt.

Repayment Plans: Your Options and Trade-offs

Federal loans offer multiple plans. The Standard 10-Year Plan has fixed payments and minimizes total interest. Graduated plans start lower and increase every two years. Extended plans stretch payments up to 25 years. Income-Driven Repayment (IDR) plans — including SAVE, PAYE, IBR, and ICR — cap monthly payments at 5–20% of discretionary income and forgive remaining balances after 20–25 years. For borrowers in public service, IDR combined with PSLF results in forgiveness after 10 years of qualifying payments. The trade-off: lower monthly payments often result in negative amortization (balance growing before payments exceed interest), and forgiven balances under IDR may be taxable income (PSLF forgiveness is currently tax-free).

Deferment and Forbearance: Pausing Payments Without Default

Deferment allows temporary payment suspension without penalty — and for subsidized loans, interest doesn't accrue during deferment. Forbearance also pauses payments, but interest continues to accrue on all loans including subsidized ones. After COVID-19 administrative forbearance, many borrowers found their balances had grown significantly from capitalized interest when repayment resumed. Always use deferment over forbearance when you qualify. Both protect your credit and prevent default, but only deferment protects subsidized borrowers from interest growth. For private loans, deferment and forbearance terms are set by the individual lender and are generally far less favorable.

Default and Its Consequences

Federal loan default occurs after 270 days of non-payment. Consequences are severe: the entire outstanding balance becomes immediately due; the default is reported to credit bureaus; the Department of Education can seize federal tax refunds, garnish wages without a court order (up to 15% of disposable income), and offset Social Security benefits. You become ineligible for additional federal financial aid. Private loan default terms vary by lender but typically occur after 90–180 days; private lenders must sue to garnish wages. If you're struggling, contact your servicer before defaulting — IDR plans can reduce federal payments to $0 if income is low enough.

Loan Forgiveness Programs: What Actually Qualifies

PSLF forgives the remaining balance after 120 qualifying monthly payments while working full-time for a qualifying employer (government or nonprofit), under a qualifying IDR plan, on Direct Loans. IDR forgiveness forgives remaining balances after 20–25 years of payments, regardless of employer. Teacher Loan Forgiveness provides up to $17,500 for teachers in low-income schools after 5 years. Private loans are ineligible for all federal forgiveness programs — this is a critical reason not to refinance federal loans into a private loan. Refinancing permanently converts federal loans to private, forfeiting all forgiveness eligibility. That conversion is irreversible.

Common Confusing Clauses in a Student Loan Agreement — Explained

These are the clauses people most often misunderstand or overlook. PlainDoc flags all of them automatically when you explain your document.

Interest Capitalization: When unpaid interest is added to your principal, it becomes part of the base amount on which future interest is calculated — compounding your debt. It occurs when you exit deferment, enter repayment, switch plans, or after forbearance ends. A $15,000 interest balance capitalized onto $50,000 creates a $65,000 base for future interest calculation.
Subsidized vs. Unsubsidized: Subsidized: the government pays your interest while enrolled half-time, during grace period, and eligible deferment. Unsubsidized: interest accrues from disbursement — you owe it even while in school. If you don't pay unsubsidized interest while in school, it capitalizes when you enter repayment.
Income-Driven Repayment (IDR): Caps your monthly payment as a percentage of discretionary income. Payments can be $0 if income is low enough. $0 payments still count toward IDR and PSLF forgiveness timelines. Balances can grow despite payments if they don't cover monthly interest accrual.
PSLF Qualifying Payment: To count toward PSLF, each payment must be: on time, the full required amount, under a qualifying plan (IDR), on a qualifying loan type (Direct Loan), while working full-time for a qualifying employer. Missing any condition means the payment doesn't count. Track annually using the PSLF Employment Certification Form.
Forbearance vs. Deferment: Both pause payments, but during forbearance, interest accrues on all loans — including subsidized — and capitalizes when forbearance ends. During deferment, the government pays interest on subsidized loans. Always request deferment first if you qualify.
