Financial aid is money to help you pay for college or career school. Its main purpose is to bridge the gap between the cost of attendance and what your family can afford to pay. Think of it not as a single lump sum, but as a package built from different types of money.

There are four main types of financial aid: grants, scholarships, loans, and work-study. Some you get to keep, some you earn, and some you have to pay back. Understanding each type is the first step toward making a smart decision about paying for your education.

Financial aid doesn't come from just one place. It flows from a few key sources, each with its own applications and rules.

The main sources are:

• Federal Government: This is the largest provider of student aid. You access it by filling out the Free Application for Federal Student Aid (FAFSA). Federal aid includes grants, loans, and work-study.
• State Government: Your state may offer its own grants and scholarships. Often, you apply for these just by submitting your FAFSA, but some states have separate applications.
• Colleges and Universities: Schools offer their own aid using money from their endowments or operating budgets. This is often called institutional aid and can include scholarships and grants based on need, merit, or other talents.
• Private Organizations: Companies, foundations, community groups, and other private organizations provide billions of dollars in scholarships each year. These require separate applications and research to find.

The best kind of financial aid is the kind you don't have to repay. This is often called “gift aid,” and it comes in two primary forms: grants and scholarships.

Grants are usually awarded based on your family's financial circumstances, which you demonstrate by completing the FAFSA. The most well-known example is the Federal Pell Grant. Many states and colleges also offer their own need-based grants.

Scholarships are most often merit-based. This means they are awarded for something you've accomplished. You might earn a scholarship for strong grades, high test scores, athletic talent, musical ability, community service, or a compelling essay. They can come from colleges or private organizations.

Unlike gift aid, some financial aid requires something from you in return. Loans must be repaid with interest, and work-study funds must be earned through a job.

Loans come in two main varieties: federal and private. Federal student loans, offered by the government, generally have more benefits than private loans from banks or credit unions. These benefits can include fixed interest rates and more flexible repayment options.

Federal loans themselves are broken down further.

For subsidized loans, the government covers the interest while you're in school at least half-time. For unsubsidized loans, interest starts accruing from the moment the loan is disbursed, and you are responsible for all of it. If you don't pay the interest while in school, it gets added to your principal loan balance.

Finally, there's work-study. The Federal Work-Study program provides part-time jobs for students with financial need, allowing them to earn money to help pay education expenses. The program encourages work related to your course of study or community service. You'll get a regular paycheck, just like with any other job, which can be used for costs like books, supplies, and personal expenses.
