Camille Wood is a personal assistant, dog sitter and host at The Second City, a comedy club in Chicago.

“During a typical week, I’m doing something for pay pretty much every day,” she said. “I needed the extra money for student loans and city living.”

The 25-year-old’s personal assistant job is full time and the rest are side gigs — jobs that allow her to make money in addition to her primary job.

Her situation isn’t that uncommon.

More than half of Americans report having a side gig at some point, according to a recent survey by SunTrust Bank.

The bank polled 2,028 adults in July. While side hustlers pull in an average of $8,794 a year, millennials are making almost 20% more at $10,972, SunTrust found.

Balancing a side gig and a full-time job can be hard, yet planning ahead makes it easier.

Managing time

Time management is key to balancing a full-time job and a side gig, said Stacey Ogden, founder of Side Hustle Teachers.

She started the program after seven years of working various side jobs, like running a motherhood blog, alongside her full-time job as a middle school music teacher to help other teachers start businesses outside the classroom.

Keep a calendar to track and optimize the free time you have, Ogden said.

“You want to make sure that you’re not looking at your schedule like ‘I have to have three full hours to sit down and accomplish something,’” she said. “If you have a full hour, you can accomplish a lot.”

Ogden wakes up before her children to get work done while it’s quiet. She uses Asana, an application designed to help teams organize and manage projects to stay on top of her to-dos.

Setting boundaries

Maintaining a balance is easier when you set boundaries.

Justine Salata, 32, has a full-time job as an associate kindergarten teacher at the Ethical Culture Fieldston School in New York, and manages weddings for Your Wedding by Lauren.

She makes around $700 per month with the side gig and works about 20 hours per wedding, she said. Communicating her schedule to loved ones was essential.

“September was absolutely insane with the start of school and four weddings,” Salata said. “I definitely let friends and family know when I’ll be working, but more importantly, I’ll let them know when I’m free.”

Find a place where you can focus on your side gig without distractions.

“My friends and family know the night before a wedding, I will be holed up in my apartment,” Salata said.

Preparing taxes

Tax season can be a “gotcha” moment for a lot of new side hustlers, said Chad Parks, founder and CEO of Ubiquity Retirement + Savings. It’s important to plan ahead properly.

For a full-time job, an employer withholds part of your Social Security and Medicare taxes, and you will have to pay a matching amount.
