What Business Can I Start with $100?

Yes, you can start a real business with $100. The businesses that work at this budget are mostly service-based — you're selling your time and skills, not a product that needs inventory. Dog walking, freelance writing, house cleaning, and virtual assistance are all viable starting points that cost less than $100 to get off the ground.

Starting a business with $100 means choosing a model where your skills are the product. You're not buying inventory, renting space, or hiring anyone. Your budget covers the basics — a few supplies, a free or low-cost website, and maybe a business card. The rest is time.

The businesses that work at this budget share a few traits: low or no equipment costs, no need for a physical location, and demand that already exists in most neighborhoods or online. Most people who start here are trading hours for dollars at first — and that's fine. It's a real business, not a side project, as long as you treat it like one.

Before you spend anything, figure out what you're selling and who you're selling it to. That's the work that actually determines whether a $100 business becomes a $50,000-a-year business.

These 6 business ideas have startup costs well under $100 and real earning potential. Each one is service-based, home-friendly, and built around skills most people already have.

Dog walking

Dog walking is one of the lowest-barrier businesses you can start. A leash and a pack of waste bags runs about $20 — that's your entire startup cost. Demand is consistent in most neighborhoods, and you can build a regular client base fast through word of mouth or a free listing on Rover or Wag.

Rates typically run $15–$25 per 30-minute walk. Walk 4 dogs a day, 5 days a week, and you're looking at $1,200–$2,000 a month before expenses. The ceiling goes up when you add pet sitting or overnight stays.

House cleaning

House cleaning is a high-demand, repeat-business model. Most clients need cleaning every 1–2 weeks, which means predictable income once you build a small roster. Basic cleaning supplies — all-purpose cleaner, microfiber cloths, a mop, and a vacuum — cost under $30 to start.

Residential cleaners typically charge $25–$50 per hour or a flat rate per job. A solo cleaner doing 3 homes a week at $150 per home brings in $450 a week — and that's a conservative number. Many clients will supply their own products once you're established, which keeps your costs near zero.

Lawn care

Lawn mowing is seasonal in most markets, but it's one of the most reliable neighborhood businesses you can build. A used push mower can be found for under $100 at a garage sale or on Facebook Marketplace — that's your biggest cost. Everything else (gas, a rake, a few bags) is minimal.

Most residential lawn jobs run $30–$80 depending on yard size. Add edging, leaf removal, or mulching and the per-job rate goes up. Lawn care businesses that start solo often grow into small crews within a season or two — the demand is there if you show up reliably.

Freelance writing

Freelance writing requires a computer and internet access — both of which you likely already have. Startup cost is effectively $0. You can find your first clients on platforms like Upwork, Fiverr, or LinkedIn, or pitch directly to small businesses that need blog content, emails, or website copy.

Rates vary widely — beginners often start at $0.05–$0.10 per word and move up as they build a portfolio. A writer producing 4 articles a week at $150 each earns $600 a week. The ceiling is high for writers who specialize in a niche like finance, health, or technology.

Virtual assistance

Virtual assistants handle administrative tasks — scheduling, email management, data entry, social media posting — for business owners who don't have time to do it themselves. You need a computer, a reliable internet connection, and basic organizational skills. Startup cost is near $0.

Virtual assistants typically charge $15–$40 per hour depending on the tasks involved. Specialized VAs — those who handle bookkeeping, customer service, or project management — can charge $50 or more. It's a business that scales well because clients often need ongoing support, not one-off projects.

Senior companion and non-medical caregiver

Non-medical senior care — companionship, light housekeeping, errands, and transportation — is a growing field. The U.S. Census Bureau projects that older adults will outnumber children in the U.S. by 2034, and the demand for in-home support is rising with that shift. Startup costs are minimal: a background check (typically $20–$40) and basic first aid certification if required in your state.

Non-medical home care providers typically earn $20–$30 per hour. Working 30 hours a week at $25 an hour puts you at $39,000 a year — and many caregivers build a roster of regular clients that provides consistent weekly income. This is one of the few $100 businesses where the work itself is genuinely meaningful.

Getting your first paying customer is the real starting line. Once money is coming in, a few structural steps protect what you're building and make it easier to grow.

Open a separate business bank account as soon as you have income. Mixing personal and business finances makes taxes harder and, if you ever form an LLC, can undermine the liability protection that structure provides. Most business checking accounts are free or low-cost at online banks.

Track every dollar in and out from day one. A simple spreadsheet works at first. The goal is to know your actual profit — not just your revenue — so you can make real decisions about pricing, hours, and whether to reinvest.

When your income is consistent, consider forming an LLC. It separates your personal finances from your business legally, which means if a client ever has a dispute or your business takes on debt, your personal assets aren't on the hook. Forming an LLC costs a state filing fee — typically $50–$500 depending on where you live — and takes a few days to a few weeks.
