Financial aid letters, credit card mail, and a first pay stub all arrive around the same time, each one full of words that are never defined anywhere. Here are fifteen of them, in plain English, roughly in the order you'll run into them.

Short answer

The fifteen terms below cover financial aid — FAFSA, SAI, work-study, grace period, subsidized and unsubsidized loans — a first paycheck (W-4 and W-2), and a first credit card and bank account: APR, utilization, secured card, overdraft, cosigner, credit freeze, minimum payment, statement date versus due date, and deferred interest. Each definition links to a deeper page where one exists.

Key points

What financial aid terms come first?

What is FAFSA?

FAFSA stands for the Free Application for Federal Student Aid. It's the form that determines eligibility for federal grants, loans, and work-study. Nearly every financial aid conversation starts with it, and it's free to file directly at studentaid.gov.

What is SAI?

SAI stands for Student Aid Index. It replaced the older "Expected Family Contribution" figure starting with the 2024–25 FAFSA, and it's used to measure financial need — it is not a bill or an amount a family is required to pay. See Federal Student Aid's explanation of the SAI for the full calculation.

In plain English

FAFSA is the form. SAI is the number that comes out the other end. Nothing about the SAI number is a bill — it's just how a school compares financial need across applicants.

What is work-study?

Work-study is a job, funded through financial aid and awarded based on financial need shown on the FAFSA. It isn't free money — it has to be earned by actually working, usually on or near campus, and it's paid out like a regular paycheck rather than credited toward tuition. Federal Student Aid's overview covers eligibility and how positions get assigned.

What is a grace period?

A grace period is the window after leaving school, graduating, or dropping below half-time enrollment before federal student loan payments must begin — commonly six months for Direct Subsidized and Unsubsidized Loans. Interest can still grow during this window on unsubsidized loans. Federal Student Aid's repayment guidance covers what to do before it ends.

What's the difference between subsidized and unsubsidized loans?

A subsidized federal loan is based on financial need, and the government covers the interest while a student is enrolled at least half-time and during the grace period. An unsubsidized loan isn't need-based, and interest starts accruing immediately — the borrower owes all of it, whether or not it's paid along the way. Federal Student Aid's comparison has the full rules.

What terms come with your first paycheck?

What is a W-4, and what is a W-2?

A W-4 is filled out when starting a job — it tells an employer how much federal income tax to withhold from each paycheck. A W-2 arrives the following January, showing what was actually paid and withheld for the year, and it's needed to file a tax return. The IRS's W-4 page explains when it's worth filling out a new one.

What terms come with a first credit card or bank account?

What is APR?

APR stands for annual percentage rate — the yearly cost of carrying a balance, expressed as a percentage. Every credit card must disclose its APR, and any penalty APR that applies after a late payment, in a required table on the application. See 12 CFR § 1026.60 for the exact federal disclosure rule.

What is utilization?

Utilization is the percentage of available credit currently being used, on one card and across all cards combined. It's one of the largest factors in most credit scores. The full mechanics, including why the statement date matters more than the due date, are in the utilization ratio glossary entry.

In plain English

Utilization is a snapshot, not a running total — it's whatever balance happens to be sitting on the card the day the statement closes, divided by the limit. Paying a card off completely by the due date doesn't undo a high utilization snapshot taken a week earlier; the statement date, not the due date, is the moment that gets reported.

What is a secured card?

A secured card requires a refundable cash deposit, which usually sets the credit limit, and it's built for someone with no credit history or a damaged one. It reports to the credit bureaus the same way a regular card does. The secured credit card guide covers how to pick one that isn't a fee trap.

What is overdraft?

Overdraft is a bank covering a transaction that exceeds the available balance, usually for a fee. Federal rules require a bank to get affirmative consent — an opt-in — before charging a fee for covering an ATM withdrawal or a one-time debit card purchase this way. See 12 CFR § 1005.17 for the exact rule.

What is a cosigner?

A cosigner signs onto someone else's credit account or loan and becomes legally responsible for the debt if the primary borrower doesn't pay. It's a much bigger commitment than being an authorized user, who owes nothing. The cosigner liability guide covers what happens if a cosigned debt goes unpaid.

What is a credit freeze?

A credit freeze, or security freeze, restricts access to a credit report so most lenders can't pull it, making it much harder for someone else to open an account in that name. It's free at all three bureaus and doesn't affect an existing credit score.

What is a minimum payment?

The minimum payment is the smallest amount that can be paid on a credit card statement to keep the account current. Paying only the minimum keeps an account in good standing, but it lets interest grow the balance for years — the college credit-building guide covers why that's one of the more expensive habits on a first card.

What's the difference between a statement date and a due date?

The statement date, or closing date, is when a billing cycle ends and a balance gets reported to the credit bureaus. The due date, usually about three weeks later, is the deadline to pay without a late fee or interest. A balance can be paid in full by the due date and still get reported as high if it wasn't paid down before the earlier statement date — a distinction the college credit-building guide covers in more detail.

What is deferred interest?

Deferred interest is a promotion, common on store and "special financing" cards, that charges interest retroactively on the entire original balance, back to the purchase date, if any amount is left unpaid when the promotional period ends. Regulators have flagged this as more confusing than a true 0% introductory APR, which never charges interest retroactively.

In plain English

A true 0% intro APR is like a toll-free bridge for a set number of months — cross it late, and interest only starts from that point forward. Deferred interest is a very different bridge: if any toll is unpaid when the free period ends, the toll collector reaches back and charges interest on the entire original amount, from the very first day — not just on whatever's left.

See CFPB's guidance on deferred-interest promotions for more.

Frequently asked questions

Is SAI the same as how much a family will pay?

No. SAI measures financial need for aid formulas — it isn't a bill, and it doesn't guarantee any specific amount of aid or out-of-pocket cost.

Does work-study pay count as income on next year's FAFSA?

Federal work-study earnings are treated differently from regular income in later aid calculations — check current FAFSA instructions or a financial aid office for the specific treatment in a given year.

Is a deferred-interest promotion ever worth it?

It can work if a balance is paid in full before the promotional period ends — but that requires tracking the exact end date carefully, since the penalty for missing it applies to the whole original balance, not just what's left.

A good next step: bookmark this page and come back to it the first time a financial aid letter, a pay stub, or a card mailer uses one of these words without explaining it. For the mechanics behind several of these terms in a real first semester, see the money lessons college actually teaches.
