When you see the Cost of Attendance listed on your student’s financial aid offer or the college’s website, the number is usually higher than the sum of tuition, fees, food, and housing. That’s because this figure includes estimates of expenses that you will likely incur throughout the school year that are not billed directly by the college. These costs are typically referred to as non-billed expenses, or indirect costs.

Being aware of these costs will help you budget more effectively, as you can anticipate what you might need in extra funds throughout the academic year. You can also consider non-billed expenses as an opportunity to cut ­costs.

Here are 9 of the most common non-billed charges incurred by college students:

1. Books

Book prices for classes vary based on college and major, and some can cost several hundred dollars. Check with the college to find out what the average student spends on textbooks each year to be prepared. To save on costs, consider renting textbooks, buying your books used, or purchasing digital versions. We have a list of websites that can help you find affordable options.

2. Supplies

Even in the age of technology, notebooks, pens, highlighters, and numerous other school supplies are still used by students at college. And in most cases, purchasing these items at an off-campus discount store will save money.

3. Laptop

Many schools require a laptop, so do your research before classes begin. Some colleges offer laptops to students, either for free or charged to your student’s account at a discount, but others don’t, so be prepared based on the school’s policy. If you’d rather purchase a laptop ahead of the semester, then check for student discounts from companies, such as Apple, Dell, or HP.

4. Course Expenses

Even though you’re already paying tuition, classes can still require additional purchases. Journalism and political science classes, for example, often require newspaper subscriptions, and students in a mathematical field may be asked to buy special software, such as MATLAB.

5. Food

Whether or not you’re paying for a meal plan, your child will likely need money on hand to pay for late-night pizza orders, off-campus lunches or dinners, and the occasional (or frequent) early morning coffee.

6. Local Transportation

If your child attends college in a city, then they may need some type of bus or subway pass to get around. Most transportation systems offer student discounts, so check online for details. If your child plans to bring a car to campus, then find out the college’s policy on parking passes and fees. Be aware that car insurance can also increase or decrease depending on where your child attends school.

7. Club Fees

Intramural sports, arts groups, sororities/fraternities, and other student organizations often require an annual fee to help offset costs and pay for group events. Prepare for fees ranging from small figures to hundreds of dollars, depending on the activity and level of involvement.

8. Travel

If your child plans to take a spring break trip or study abroad for a semester, travel expenses are guaranteed. Try to get an idea of your student’s plans for the year before the fall semester begins. Travel costs can also vary significantly depending on how far your student’s college is from your home. If you’re within driving distance, then a bus is usually a financially savvy option. If your student must fly to get home, then try to plan visits in advance to lock in lower flight prices.

9. Dorm Needs

If your child plans to live on campus, then they will need supplies to outfit their dorm. Most dorms come with only the bare minimum: a bed, dresser, and desk. Students typically need to provide their own bedding, TV, appliances, and any sort of decoration. If your student has roommates, then make sure they coordinate with them before move-in day to avoid bringing multiples of the same item.

These are just some indirect costs you may expect. Check with a college directly to get an accurate estimate of what students typically spend for their non-billed expenses. Though extra college costs are inevitable, being aware and prepared can help you lower the overall cost of college.
