Create a college financial plan to avoid stressful debt in the future.
Students and parents who make a plan to pay for college have more success making college affordable. It begins with a conversation during the junior year of high school, or early on in the senior year, to determine who is going to pay for college and which components. Through this discussion, parents can set the ground rules and give students realistic expectations. That’s why calculators are vital to the college planning process. They provide a pretty accurate estimate on college costs, financial aid packages, and your Student Aid Index (SAI) , which is ultimately determined on the FAFSA.

Best Financial Aid and Loan Calculators

To help you start the conversation – and to assist you in your plan to pay for college – we’re highlighting our favorite student calculators from our sister site, FinAid. These calculators are tried and true and should be utilized by students and their parents/guardians to make the most informed college decisions.

Student Aid Index (SAI) Calculator

The best way to determine your estimated financial aid package is:
COA – SAI = Financial Need
COA stands for Cost of Attendance, and SAI stands for Student Aid Index. The cost of attendance can be found on any college website under their Financial Aid section. Filing the Free Application for Federal Student Aid, or FAFSA, determines the SAI. The above equation informs you of your Financial Need. Once the FAFSA is filed, schools take the Financial Need number and attempt to bridge the gap between what you can pay and how much college costs. They may do so with grants and/or work study. However, they may also include student loans in their financial aid package as well. An SAI Calculator can help you determine how much your family will be expected to pay towards college. This is a great calculator to utilize during your junior, or even sophomore, year of high school.

As you come face-to-face with the realities of paying for college, you may find that between your family’s contribution and your financial aid package, you still do not have enough resources to pay the full cost of attendance. Your only remaining option may be to take out student loans to cover the cost of attending college. Though that can sound scary to a lot of students and parents, it doesn’t have to be. Just follow a few basic rules for borrowing:
  1. Never borrow more than your annual salary after graduation. Research annual salaries of jobs that interest you – or find the average starting salary for all college graduates. That will give you a limit on how much to borrow.
  2. Borrow federal first, then seek out private loans. Federal student loans have the lowest interest rates. By borrowing federal first, you save more money over time on your student loan payments.
  3. Estimate loan payments before borrowing. To help you make the wisest student loan decisions, it’s vital to estimate your monthly payments after graduation. Before you even borrow, you’ll have a big picture view of how student loans will impact your life after graduation.
