If you’ve spent five minutes on social media, you’ve seen them: the videos promising $10,000 a month from your sofa with “zero effort”. We’ll save you the suspense. That’s not how it works for almost anyone.
What does work is less glamorous: picking one realistic idea, putting in a few focused hours a week, and sticking with it long enough to get good. The eight side hustles below cost under $100 to start. None of them are get-rich-quick. All of them are real.
One piece of advice before you scroll: choose one and give it three months. Trying five hustles at once is the number one reason people give up. And keep a simple record of what you earn and spend from day one, because side income is usually taxable.
1. Freelance writing or editing
Cost to start: basically nothing · First payment: often within a few weeks · Great if: you write clearly and hit deadlines
Every business needs words: blog posts, website pages, newsletters, proofreading. Write two or three samples on a topic you know well, then start pitching on freelance sites or straight to small businesses. A word of warning: AI has made generic writing cheap. The writers still doing well are the ones who know a subject inside out, like finance, health or software. Your day job might be your biggest advantage here.
2. Virtual assistant
Cost to start: $0 · First payment: a few weeks · Great if: you’re the organised one in your friend group
Busy business owners will happily pay someone to tame their inbox, manage their calendar, do research or answer customer emails. Pick three or four things you’re genuinely good at, set a clear rate, and look for clients in online founder communities as well as freelance marketplaces.
3. Selling digital products
Cost to start: $0 to $50 · First payment: unpredictable, often months · Great if: you’re creative and patient
Planners, templates, spreadsheets, photo presets, short guides. Make them once and sell them over and over on Etsy, Gumroad or similar. Sounds dreamy, right? The catch is competition. The products that sell solve one specific problem for one specific group of people. Treat your first few months as research into what people actually buy.
4. Online tutoring
Cost to start: $0 to $50 for a decent headset · First payment: within weeks · Great if: you know a subject, language or instrument well
Maths, English, coding, guitar, exam prep. If you can explain it, someone wants to learn it. Tutoring platforms help you find students fast but take a cut. Once you’ve built up regular students and good reviews, you can take bookings directly and keep more of every lesson.
5. Flipping secondhand finds
Cost to start: $50 to $100 for your first stock · First payment: days to weeks · Great if: you love a bargain hunt
Buy underpriced stuff at charity shops, car boot sales or clearance aisles, and resell it on eBay, Facebook Marketplace or Vinted. Here’s a smart way to start for free: sell things you already own. You’ll learn what sells, how to take good photos and how to price, all without risking a penny. Then pick one category, like branded clothing, electronics or books, and get to know it really well.
6. Social media for local businesses
Cost to start: $0 to $30 for design and scheduling apps · First payment: a few weeks · Great if: you already live on Instagram or TikTok
Think about the café, barber or gym down your road. They know they should post more. They just don’t have the time. Offer a simple monthly package (say, three posts a week plus replying to comments). To get started, help one or two businesses at a discount in exchange for an honest testimonial.
7. A blog or YouTube channel
Cost to start: $0 to $100 · First payment: usually 6 to 12 months, sometimes longer · Great if: you enjoy creating and can play the long game
Yes, this is exactly what we’re doing here, so we’ll be straight with you: it’s the slowest option on the list. Content sites earn from ads, affiliate links and sponsorships, and it takes a lot of helpful content before the money shows up. The upside is that once traffic arrives, it can keep earning while you sleep. Pick a topic you could happily talk about for years.
8. Pet sitting and dog walking
Cost to start: close to $0 · First payment: days · Great if: you’d rather hang out with dogs than spreadsheets
Not everything has to happen on a laptop. Pet care apps and local community groups make finding clients easy, and happy owners come back again and again. Just check whether you need insurance where you live before you start.
How to pick yours
- Need cash soon? Go for service work: freelancing, VA work, tutoring or pet sitting. You get paid for every job.
- Want income that grows without more hours? Digital products or content. Just know they take longer.
- Busy schedule? Reselling and digital products fit neatly into odd evenings and weekends.
Spot the scams
Walk away from anything that wants a big payment upfront, guarantees income, pays you mainly for recruiting friends, or pushes you to “decide today”. Real side hustles mean real work for real customers. If it sounds too easy, trust your gut.
Where to go from here
You don’t need much money to start earning on the side. You need one good idea, a bit of patience and a few hours a week. Pick the one that made you think “I could actually do that”, and start this week. For more ideas, take a look at our Side Hustles section.
