The trips home for the holidays can add to the expense of your child’s college experience. Along with paying for the cellphone and Uber and library fines. You might actually be relieved to see the graduation fees by the time you get there. (Kathy Willens/AP)

Here are 10 college costs you probably hadn’t thought about:

Annual boosts in tuition/housing. These costs don’t stay static. Most years, these increase by 1 percent to 3 percent.

Storage fees. Don’t forget about where your kid plans to store all of that college “stuff” over the summer. It’s going to cost you to rent or share storage space. And then there’s the cost of transporting it, if your kid doesn’t have a car.

Room decoration. No, you won’t have to carpet or wallpaper your kid’s dorm room, but even minimal decorations such as posters, lights and knickknacks have a price. Once they move off campus, there’s furniture and sometimes appliances to purchase.

Rental insurance. Your home insurance policy may — or may not — cover your kid’s college digs. Better check.

Changing majors. This one can be a killer. Pay for a year or two of classes in one major, but then your kid changes to another. This move can cost many thousands of dollars in additional required classes. Much cheaper to change majors earlier than later.

Cellphone. No matter what mobile phone plan your family is on, it’s almost guaranteed that your kid will consume more data at college.

Personal hygiene. College will likely be the first time your kid comes face to face with the high costs of keeping clean.

Late payments and fines. Few college students are able to avoid the maze of late payments and fines at college. Those library fines can be particularly nasty.

Printing and photocopying. Your kid might need a printer — or plan to hook up to one in the dorm or elsewhere at school. Either way, it adds up.

Graduation fees. It’s not just the cap and gown that will cost you. So will the photos, celebration party and, of course, graduation gifts. Most parents are only too happy to pay this one.
