Student loans are borrowed money repaid with interest. Federal loans offer fixed rates and flexible repayment options — private loans offer fewer protections. This guide explains how both work, how to apply, and how to avoid the most common mistakes families make.
Student loans are borrowed money that must be repaid with interest, used to pay for college tuition, housing, books, and living expenses. There are two main types: federal student loans (issued by the U.S. government with fixed interest rates and flexible repayment options) and private student loans (issued by banks and lenders with variable or fixed rates and fewer protections). Federal loans are almost always the better starting point for families.

Federal loans offer protections that private loans do not. Understanding this difference before borrowing can save your family tens of thousands of dollars and significant stress at repayment time.
Federal Student Loans (issued by the U.S. Department of Education):
Private Student Loans (issued by banks, credit unions, SoFi, Sallie Mae, etc.):
The rule most financial advisors follow: Exhaust all federal loan options before considering private loans. Only use private loans to fill a gap that grants, scholarships, and federal loans cannot cover.
Who Benefits Most from Federal Loans: All students — but especially those pursuing careers in public service, non-profits, or education who may qualify for loan forgiveness.
Who Might Consider Private Loans: Students at professional schools (law, medical, dental) who have exhausted federal limits and have a strong co-signer with excellent credit.
Interest is charged daily on your outstanding loan balance. On a $30,000 loan at 6.53%, approximately $5.37 accumulates in interest per day. Over a 4-year degree, if no payments are made while in school, unpaid interest is added to the principal balance — a process called capitalization.
Example: $30,000 in Unsubsidized Direct Loans at 6.53%
| Scenario | Starting Balance | Interest During School | Balance at Graduation | Total Repaid (10-yr) |
|---|---|---|---|---|
| Unsubsidized — no payments | $30,000 | ~$8,500 | ~$38,500 | ~$52,000 |
| Subsidized — no interest during school | $30,000 | $0 (gov pays) | $30,000 | ~$40,500 |
| Unsubsidized — pay interest during school | $30,000 | Paid monthly | $30,000 | ~$40,500 |
Key insight: Subsidized loans (only available based on financial need) are significantly cheaper because the government pays your interest during school, grace period, and deferment. Always accept subsidized loans before unsubsidized.
Pros of understanding this early:
Cons of the unsubsidized structure:
Who Should Pay Interest During School: Any family with the cash flow to do so — even $50–$100/month during school significantly reduces final balance.
You cannot access federal student loans without completing the FAFSA (Free Application for Federal Student Aid). The FAFSA determines your Expected Family Contribution (EFC), now called the Student Aid Index (SAI), and unlocks not just loans but also Pell Grants, work-study, and institutional aid.
The FAFSA process:

Pros:
Cons:
Who Should File FAFSA: Every student planning to attend college, regardless of family income. Many merit-based scholarships and institutional grants require FAFSA completion.
Federal loans offer 8 repayment plans. The standard plan is not always the best. The right plan depends on income, career path, and whether your student is pursuing loan forgiveness.
Major Repayment Plans:
| Plan | Payment | Repayment Period | Best For |
|---|---|---|---|
| Standard | Fixed — pays off in 10 years | 10 years | Fastest payoff, lowest total interest |
| Graduated | Starts low, increases every 2 years | 10 years | Expect income to grow quickly |
| Income-Driven (SAVE/IBR/PAYE) | 5–10% of discretionary income | 20–25 years | Low income post-graduation |
| Extended | Fixed or graduated | 25 years | Needs lower payment, not forgiveness-eligible |
Income-Driven Repayment (IDR) key fact: After 20–25 years of payments, any remaining balance is forgiven — though currently taxable as income in most states.
Public Service Loan Forgiveness (PSLF): Borrowers who work full-time for government or 501(c)(3) non-profits for 10 years and make 120 qualifying payments can have their remaining balance forgiven — tax-free.
Pros of IDR:
Cons of IDR:
The biggest mistakes happen before the first loan is even disbursed. Knowing them in advance is the simplest way to avoid six-figure regret.
| Feature | Federal Loans | Private Loans |
|---|---|---|
| Interest rates (2025–26) | 6.53%–9.08% fixed | 4%–16% (variable or fixed) |
| Income-driven repayment | Yes | Rarely |
| Forgiveness programs | Yes (PSLF, IDR) | No |
| Deferment/forbearance | Yes | Limited |
| Credit check required | No (most) | Yes |
| Co-signer required | No | Often |
| Borrowing limit | Set by Congress | Up to cost of attendance |

What is the difference between subsidized and unsubsidized student loans?
Subsidized loans are need-based and the government pays the interest while you are in school, during the grace period, and during deferment. Unsubsidized loans are not need-based and interest accrues from the date of disbursement. Always accept subsidized loans first.
How much student loan debt is too much?
A common guideline: total student loan debt should not exceed your expected starting salary. If you expect to earn $50,000/year, try not to borrow more than $50,000 total. Borrowing significantly more than your expected starting salary often leads to repayment hardship.
Do student loans affect credit score?
Yes. Student loans appear on your credit report and payment history affects your score. On-time payments build credit; missed payments damage it. Federal loans have a 270-day grace period before default; private loans vary.
Can student loans be forgiven?
Federal student loans may be forgiven through Public Service Loan Forgiveness (10 years in public service), Income-Driven Repayment plans (after 20–25 years), or targeted programs. Private loans have no forgiveness programs.
What happens if my student cannot make loan payments?
Federal loans offer income-driven repayment (reducing payments to as low as $0), deferment, and forbearance. Private lenders offer limited hardship programs. Federal loans are significantly more flexible during financial hardship.
Can parents borrow student loans for their child?
Yes. Federal Parent PLUS Loans allow parents to borrow up to the full cost of attendance minus other aid, at a fixed rate of 9.08% for 2025–2026. These are in the parent's name — the parent is responsible for repayment, not the student.
What is the student loan grace period?
Federal Direct Loans have a 6-month grace period after graduation, leaving school, or dropping below half-time enrollment before payments are required. PLUS loans typically enter repayment immediately, though deferment is available.
When should my child start repaying student loans?
Federal loans begin repayment after the 6-month grace period. Making payments early — even small ones — reduces total interest paid. Interest-only payments during school are a smart strategy for families with cash flow.
