Why Learn Student Loan Terms?
Student loans come with their own vocabulary. When you read your loan agreement, talk to your loan servicer, or compare repayment plans, you will meet terms like 'capitalization,' 'deferment,' and 'subsidized.' Understanding this language helps you know what you owe, when payments start, and how interest grows.
This glossary explains common terms borrowers see on statements, in applications, and in program descriptions. It is organized alphabetically so you can look up a word quickly and then explore related entries.

A–C: Accrued Interest, Capitalization, Cosigner
Interest begins to add up as soon as you take out certain loans. Terms in this range describe how interest is calculated and how another person can share responsibility for your loan.
- Accrued interest: Interest that accumulates on your loan when it is not paid as it is charged. For example, if your student loan has accrued $200 in unpaid interest by the time you enter repayment, that amount is added to your loan balance.
- Capitalization: The process of adding unpaid accrued interest to the principal balance of your loan. After capitalization, your loan principal increases, and future interest is charged on the higher balance. This can happen when a deferment ends or when you enter repayment on certain loans.
- Cosigner: A person who agrees to be legally responsible for a loan if the primary borrower does not repay it. Lenders may require a cosigner when a borrower lacks a credit history or a steady income. The cosigner’s credit may be affected by the loan, and a cosigner may be able to request to be released after a certain number of on-time payments, depending on the lender.
D–G: Default, Deferment, Direct Loan, Grace Period
These terms cover what happens when you struggle to pay, what breaks do borrowers can get, and the most common federal loan type.
- Default: Failure to repay a loan according to the terms of your promissory note. For federal student loans, default typically occurs after 270 days of missed payments. Defaulting can have serious consequences, including damage to your credit and possible wage garnishment.
- Deferment: A period when you are allowed to temporarily stop making loan payments. During deferment, interest does not accrue on subsidized loans, but it does accrue on unsubsidized loans. You usually need to apply and meet specific criteria, such as being enrolled in school or experiencing economic hardship.
- Direct Loan: A federal student loan issued under the William D. Ford Federal Direct Loan Program. These loans have fixed interest rates and are funded by the U.S. Department of Education.
- Grace Period: A set period after you graduate, leave school, or drop below half-time enrollment before you must begin repaying your loan. For most federal loans, the grace period is six months. Interest may accrue during this time depending on the loan type.
H–O: Income-Driven Repayment, Loan Servicer, Origination Fee
These terms explain repayment options, who handles your account, and costs that are taken out of your borrowed amount.
- Income-Driven Repayment (IDR): A federal repayment plan that sets your monthly payment based on your income and family size. After a certain number of years of qualifying payments, any remaining loan balance may be forgiven. There are several IDR plans, each with its own formula.
- Loan Servicer: The company that manages your loan account on behalf of the lender. Your servicer sends you statements, collects payments, and helps you explore repayment options. For federal loans, you can find your servicer through your account on StudentAid.gov.
- Origination Fee: A charge that the lender assesses to process a new loan. For federal student loans, the origination fee is a percentage of the loan amount and is deducted from the loan proceeds before they are sent to you. This means you receive slightly less than the total amount you borrow and must repay.
P–S: Principal, Private Loan, Repayment Plan, Subsidized Loan
Understand the core parts of your loan balance and the distinction between public and private borrowing.
- Principal: The original amount of money you borrowed, before interest and fees are added. Your loan balance is the principal plus any accrued interest and fees.
- Private Student Loan: A non-federal loan from a bank, credit union, or other private lender. Private loan terms vary and can include variable interest rates, flexible repayment timelines, and less borrower protection than federal loans. Private loans often require a credit check and may need a cosigner.
- Repayment Plan: A schedule that determines your monthly payment amount and the length of time you have to repay your loan. Federal loans offer several repayment plans, including standard, graduated, extended, and income-driven plans.
- Subsidized Loan: A federal student loan based on financial need. The government pays the interest on a subsidized loan while you are in school at least half-time, during the grace period, and during deferment. Because interest does not accumulate during these times, subsidized loans can be less expensive over time.
T–Z: Unsubsidized Loan, Variable Interest Rate
The last set of terms covers loans that begin accruing interest immediately and loans whose rates can change over time.
- Unsubsidized Loan: A federal student loan that is not based on financial need. You are responsible for all interest on an unsubsidized loan, and interest begins to accrue as soon as the loan is disbursed. You can choose to pay the interest while in school, but if you do not, it may be capitalized and added to your loan balance.
- Variable Interest Rate: An interest rate that can change over time, usually based on an underlying index, such as a market rate. A variable rate may go up or down during repayment, which can affect your monthly payment and total interest cost. Federal student loans have fixed rates, but private loans may offer variable rates.
The Fine Print: Reading Your Loan Documents
When you take out a student loan, you sign a promissory note—a legal document that spells out the terms and conditions of your loan. Later, you will receive disclosures from your loan servicer that show your interest rate, fees, and repayment schedule.
Before you borrow or sign any paperwork, take time to review these key items: whether the interest rate is fixed or variable, who pays interest during school and other deferment periods, what fees are deducted from the loan, and what options you have if you struggle to make payments. If anything is unclear, ask your loan servicer or the financial aid office at your school for an explanation.
- Always read the loan disclosure statement, not just the summary. It shows the loan amount, fees, interest rate, and total cost.
- Keep a folder of your loan documents, including the Master Promissory Note and any repayment schedules, so you can refer to them later.
- Understand your grace period and the date your first payment is due, so you are not surprised when repayment begins.
Frequently asked questions
What does 'capitalization of interest' mean?
Capitalization of interest means that unpaid accrued interest is added to your loan’s principal balance. For example, if you have a $5,000 loan and $500 in unpaid interest accrues while you are in deferment, after capitalization your loan principal becomes $5,500. Future interest is then calculated on that higher amount, so you end up paying interest on interest. Capitalization often occurs when a period of deferment or forbearance ends, or when you enter repayment on certain loans.
What is the difference between forbearance and deferment?
Both forbearance and deferment allow you to temporarily postpone or reduce your loan payments, but they differ in how interest is treated. During deferment, you typically do not need to make payments, and for subsidized loans, the federal government pays the interest that accrues. Unsubsidized loan interest still accrues during deferment. During forbearance, you also pause or reduce payments, but interest always accrues on all loan types, including subsidized loans. Deferment is often granted for specific reasons like school enrollment or economic hardship, while forbearance may be given for shorter periods of financial difficulty.
What is an origination fee on a student loan?
An origination fee is a charge assessed by the lender to cover the cost of processing a new loan. For federal student loans, the origination fee is a percentage of the loan amount and is deducted from the loan before the money is given to you. For example, if you borrow $10,000 with a 1% fee, you will receive $9,900, but you are responsible for repaying the full $10,000. Private lenders may also charge origination fees, but their terms vary, so you should check your loan disclosure.
What does 'loan servicer' mean?
A loan servicer is a company that manages your loan account on behalf of the lender. They are responsible for billing you, processing your payments, and helping you apply for repayment plans, deferment, or forbearance. Even if a different company originally issued your loan, your servicer is your main point of contact for questions about your balance and payment options. For federal loans, you can find your assigned servicer by logging into your account on StudentAid.gov.
What is a co-signer and how does it affect a loan?
A co-signer is someone who agrees to take on legal responsibility for your loan if you fail to repay it. Lenders often require a co-signer when the borrower has limited credit history or income. The co-signer’s credit history and income are considered in the loan application, which can help you qualify for a loan or get a lower interest rate if the co-signer has good credit. However, the co-signer is equally responsible for the debt, and any late or missed payments can harm their credit score. Some lenders offer co-signer release after a certain number of on-time payments, but not all do.
