A side hustle can help you increase your income. Whether you need more money to pay down debt, boost your savings, or deal with rising living costs, there are plenty of side hustle ideas to explore.

Even better, you don’t have to work on an app or platform to do this kind of work. You can start your own business and deal with clients directly.

You may assume you’ll need to invest significant money when starting a side hustle, but that’s not always true. You can start a business for little to no startup costs. I’ll share a few affordable business ideas that could help boost your checking account balance.

1. Freelance writer or editor

Many businesses hire freelance writers and editors to help them create content, such as website copy, blog articles, and press releases. If you’re a good communicator, are creative, have an eye for details, and can juggle multiple projects, you may want to explore becoming a freelance writer or editor.

The nice thing about this business idea is you don’t have to invest money to get started. If you own a computer and have internet access, you can get started immediately.

Some writers and editors use software and tools, like spelling and grammar software, but there are also free tools you can use to help you do your job better — like Google Docs. You can keep your costs low with this kind of business, especially in the early days.

2. Tutor

Another business idea to explore is becoming a tutor. Other people are looking for one-on-one instruction in subjects or skills they’re struggling with — and you can help them. If you’re a good problem solver and an active listener and can explain things clearly and compassionately, you may be a good fit for this side hustle.
