Back to School Money Ideas: 12 Ways Teens Can Earn Cash All Year

Back-to-school season costs money — new clothes, supplies, activity fees, parking permits. But it also creates money-making opportunities. Here's how to earn your way through September and build income that lasts all year.

1. Tutoring Freshman and Sophomore Students

Earnings: $25–45/hr | Effort: 2–4 hrs/week

You survived last year's classes. Sophomores and freshmen need help in the exact classes you're best at. Post in your school's subreddit or Facebook group: "AP/Honors student offering tutoring in [Math/Biology/Chemistry], $30/hr, flexible times after school."

One student at $30/hr for 3 hours a week = $360/month. Two students = $720/month. This requires zero equipment, zero investment, and you make money while actually studying.

2. School Supply Reselling (Flipping)

Earnings: $50–$300 per school supply run | Effort: 1 afternoon

Teachers spend their own money on classroom supplies. They're also buying personal notebooks, planner refills, pens, and sticky notes. Find a teacher Facebook group or a local educator group and offer to do a Costco/Big Lots run for them. Buy in bulk, charge a 15–20% markup, deliver to the school.

Or: buy bulk school supplies at back-to-school sales (July/August clearance at Staples, Target, Walmart), then sell individual items to other students at a markup in the first week of school.

3. Homework Group Hosting

Earnings: $60–$120/week | Effort: 3–4 hrs/week

Organize 3–4 students who need help in the same class. Meet once a week for 90 minutes after school. Charge $15–20 per student per session. That's $60–$80 per session, and your own study session is built into the job.

Post on your school's Facebook group: "Weekly AP/Pre-Calc/Chem study group — Wednesdays 4–5:30pm at the library. $18/student, limited to 4 spots."

4. Social Media Ghostwriting for Teachers

Earnings: $100–$200/month | Effort: 3–4 hrs/month

Yes, seriously. Teachers use social media to post about school events, classroom activities, and parent communications. Most of them are terrible at it. If you can post a photo, write a caption, and use relevant hashtags, you can manage a teacher's Facebook or Instagram account for $100/month.

One teacher pays for it. Word spreads. Do three teachers = $300/month for 2 hours of content work.

5. Parking Lot Car Watch (for drivers)

Earnings: $5–10/car per day | Effort: 30 min/day

If your school has a big parking lot, offer to watch cars during school hours. Some students leave valuables visible in cars and worry about break-ins. You sit in the lot during lunch and free periods — you're there anyway — and make $5 per car you watch. Easy money for zero effort.

6. Custom Phone Wallpaper & Lock Screen Design

Earnings: $5–15/design | Effort: 20 min each

Make custom phone wallpapers with a teen's name, school mascot, or sports team. Sell them on Etsy or through Instagram. Canva is free. You can design a custom wallpaper in 20 minutes and sell it for $8–$15. Cost to you: zero.

Post in school Facebook groups: "Custom phone wallpapers — any school, any mascot, $10. Send me your school name and colors." No inventory. No shipping. Instant delivery.

7. Personalized School Supplies Dropshipping

Earnings: $20–$100/week | Effort: 2–3 hrs/week

Buy bulk personalized pencils, pens, or notebooks with your school's name on them ( Alibaba or 4imprint.com for as low as $0.30–$0.50 each), then sell them at the school store or in the cafeteria during the first two weeks. Custom pens with the school name = $1 cost to you, $3–$4 sale price to other students. Simple margin.

8. Test Prep Note Packet Reselling

Earnings: $5–$15 per packet | Effort: 2–3 hrs to create

If you took AP, Honors, or dual enrollment classes, your notes are an asset. Turn your study guides into clean, formatted note packets (use Google Docs). Sell them to underclassmen for $8–$15 each. One packet design = sell it 20 times.

Post: "AP [Subject] Notes for Sale — $12. DM me."

9. Custom Phone Case Decoration

Earnings: $15–$35/case | Start-up: $20–$40

Buy plain clear phone cases (Amazon, $5–8 each), decorate them with resin art, custom designs, or rhinestones, and sell to students at school. Or use a Cricut vinyl cutter ($30–$50 for a small one) to make custom phone case decals. Target the back-to-school crowd — they buy new phone cases when school starts.

10. School Spirit Merch Table

Earnings: $100–$400 in the first 2 weeks | Start-up: $30–50

Design simple T-shirt graphics with your school mascot (use Canva free), order them from a print-on-demand service like Printful or a local screen printer (15–20 shirts minimum), and sell them in the cafeteria or at school events. Custom school tees = $15–$20 cost to you, $25–$35 sale price.

Order 20 shirts at $8 each, sell at $25 = $340 profit. Pre-sell by posting in school Facebook groups before you order.

11. Tech Repair for Fellow Students

Earnings: $30–$80 per repair | Start-up: $30

Broken screen protector? Slow laptop? iPhone storage full? All of these are solvable problems. Buy a basic screen repair kit ($25–30 from Amazon), watch a YouTube tutorial, and start fixing fellow students' phones and tablets. Charge $30–$50 for screen protectors + installation, $40–$80 for data transfers or laptop tune-ups.

Set up a table in the school library or common area with a sign: "Phone/laptop help — $30. See me." You handle 1–2 repairs a week = $120–$160/month.

12. School Year Photo Session Packages

Earnings: $50–$150 per session | Start-up: $20–40

Got a phone with a decent camera? Offer mini photo sessions for students who want fall photos or sports portraits. $50 for 15 edited photos, $100 for 30 photos with 3 outfit changes. Do 4 sessions in September = $400–$600.

Post in school Facebook groups: "Fall photo sessions — $75, 20 edited photos, outdoor setting. DM to book." The demand is real and the competition is low in most school communities.

The $500/Month Target: How to Get There

You don't need to do all 12 of these. You need to pick 2–3 that fit your schedule and execute. Here's what 2–3 of the ideas above look like together:

12 hours a week. Under $25 to start. $700/month. That's the math for a serious teen side hustler during the school year.
