A cheap small business idea can be the ideal way to make passive income.
Passive income is money earned separately from your main job, usually with little effort required. As the cost of living increases, finding a side hustle to earn passive income can be a great way to boost your finances.
Take a look at these 15 passive income ideas to see if there’s one that aligns with your skills and interests.
1. Dropshipping
Dropshipping is a popular way to make a passive income, especially if you only have a small budget to get you started.
Dropshipping allows you to set up an online store and sell products without needing to invest in inventory. Instead, each time a customer makes a purchase your dropshipping provider will ship the item.
Your chosen dropshipping provider handles everything, from processing the order to shipping the goods and dealing with returns.
Dropshipping is a cheap and easy way to sell products online without needing to invest a huge amount of time and money, just be sure to select a reliable supplier to avoid issues.
- Resources required: You’ll need to set up a website or online store to sell your products and will need to source a reliable dropshipping supplier too.
- Skills/qualifications needed: None
- Cost: £0 – technically you can set up your dropshipping store for free and won’t need to pay a penny until someone makes a purchase.

2. Print-on-demand
Print-on-demand can be a great passive income idea for those with creative talent but who don’t want to start a printing franchise.
If you’re an artist then a print-on-demand business allows you to print designs onto white label products such as mugs or tote bags.
Like with dropshipping, you only print each item once an order has been placed and you usually do so via a print-on-demand supplier. This helps to keep costs to a minimum.
You only pay for print-on-demand products once you’ve made a sale. If you enjoy getting creative then print-on-demand could be the perfect passive income choice.
- Resources required: You’ll need to set up a website or online store to sell your items and find a reliable print-on-demand supplier.
- Skills/qualifications: Artistic skills will be a plus but not an essential.
- Cost: £0 – technically you can set up your print-on-demand store for free and won’t need to pay a penny until someone makes a purchase.
3. Spare room rentals
We all know that renting out property can be lucrative but we don’t all have the savings to invest in purchasing a property.
If you have a spare room in your home, renting it out either as a long-term rental or as a holiday let can earn you a considerable amount of passive income.
Depending on your situation you can rent out your spare room privately or via a third party such as Airbnb (although be warned, you may need to pay tax).
Be sure to check any agreements you may have with your own landlord first and consider adding an application process to be sure you’re comfortable with whoever takes the room.
You wouldn’t be the only one considering this option either, data from SpareRoom shows an 89% increase in the number of homeowners renting out a spare room between 2021 and 2024.
- Resources required: A spare room that you’re willing to rent out to a stranger.
- Skills/qualifications: None
- Cost: The only expense will be investing in landlord insurance which starts at as little as £3 per month.
4. Car parking rentals
It’s not just the inside of your home you can rent out. If you have off-road parking then why not rent out your parking space?
People are always looking for cheap parking and if you live in a desirable location or nearby key attractions (e.g. football stadiums, arenas etc) then renting out your space can be lucrative.
There are plenty of third-party apps you can use to promote your space such as YourParkingSpace. You’ll just need to set your price and your terms and conditions.

- Resources required: Nothing other than a bank account and internet connection.
- Skills/qualifications: None
- Cost: Technically £0 however you will need to spend money to make the purchases in order to earn rewards.
6. Stock photos
If you’re a photographer then you may be used to being paid for the time and effort you put into photo shoots.
While this isn’t a passive income source, there is a way to make passive income through your skills with a camera that doesn’t involve starting a full-time photography business: stock photos.
You can sell your photo portfolio to stock photography websites (or start your own) and depending on the site and their terms and conditions, either get paid every time your image is downloaded or in one lump sum.
There are already millions of stock photographs online, however, so you’ll need to ensure yours stand out from the crowd to break through an already saturated market.
- Resources required: A quality camera.
- Skills/qualifications: Photography skills.
- Cost: £0 once you’ve invested in a camera.
7. Online courses
If you have a skill that you think you can teach others then why not create an online course?
It’s never been a better time for educators to get online and sell digital courses to students. Online learning is the fastest growing education market and it’s predicted that the number of people taking online courses will rise to 57 million by 2027.
You will need to invest initial time and effort into creating the course, pre-recording lessons, and creating resources and worksheets but the good thing is this will all sit online meaning you don’t need to house physical items. If you build a website with Squarespace, you can even use the specialist Squarespace Courses platform.
Another option is to start a podcast. Some of the best online tutors now teach their students via audio so they can fit lessons easily into their day.
Ideally, you will also automate your marketing and sales funnel to make this a truly passive income source.
