“Start for free.” “Zero investment required.” “Begin with nothing.”
These phrases appear constantly in online business marketing, and they do more damage to beginners than almost anything else in this space. Not because they’re always outright lies, some models genuinely do have low startup costs, but because they set expectations that don’t survive contact with reality.
After 16 years building things online, here’s my honest breakdown of what different online business models actually cost to start. Not the best case. The realistic case.
Why “Start for Free” Is Usually Misleading
Before the model-by-model breakdown, it’s worth understanding what “free” usually means in this context.
When someone says you can start a dropshipping business for free, they mean you can technically open a Shopify trial account without paying immediately. They don’t mean you can run it without money, the products cost money, the advertising costs money, and the Shopify subscription kicks in once the trial ends.
When someone says you can start affiliate marketing for free, they mean you don’t need to buy a product to promote. They don’t mean you can build an audience, a website, and a content library without investing anything.
“Free to start” usually means “no initial product purchase required.” It almost never means “no money required to reach your first income.”
Here’s what each model actually costs.
Affiliate Marketing, Content-Based
Realistic startup cost: £50 to £300
The model: build a website, create content, earn commissions from affiliate links.
What you actually need to pay for: a domain name (around £10 to £15 per year), web hosting (£5 to £15 per month on a basic plan), and potentially a premium theme or keyword research tool if you’re serious about SEO.
The real cost isn’t money, it’s time. A content affiliate site takes six to twelve months to gain meaningful traction. The financial outlay is low. The time investment before you see a return is significant.
Where costs escalate: Keyword research tools like Ahrefs or Semrush run £80 to £150 per month and aren’t strictly necessary to start but become important at scale. If you outsource content writing instead of doing it yourself, costs rise substantially.
Affiliate Marketing, Paid Traffic
Realistic startup cost: £1,500 to £5,000
The model: run paid ads to affiliate offers and profit on the margin between ad spend and commissions.
What you actually need to pay for: ad spend during the testing phase. Testing a new offer on Facebook or Google Ads properly, enough data to make meaningful optimisation decisions, typically requires £500 to £2,000 per offer before you know whether it’s viable. Most beginners test multiple offers before finding something that works.
The honest warning: This model requires capital you’re willing to lose during the learning phase. The financial floor is real and most courses in this space significantly understate it.
Dropshipping
Realistic startup cost: £500 to £3,000
The model: sell physical products online without holding inventory, fulfilling orders through a supplier.
What you actually need to pay for: Shopify subscription (£29 to £79 per month), domain, apps, product testing (ordering samples to check quality), and advertising to drive traffic to the store.
Advertising is where most of the cost lives. A Facebook or TikTok Ads campaign for a new dropshipping store requires meaningful spend before you identify winning products and creatives, typically £500 to £2,000 in ad testing before a campaign is reliably profitable.
Where costs escalate: Dropshipping with domestic suppliers (for faster shipping) costs more per unit than AliExpress sourcing. High-ticket dropshipping requires larger ad budgets but generates higher per-sale returns.
Amazon FBA
Realistic startup cost: £2,000 to £10,000
The model: source a private-label product, ship it to Amazon’s warehouses, and sell through Amazon’s marketplace.
What you actually need to pay for: product inventory (typically a minimum order of 200 to 500 units from a supplier, costing £500 to £3,000 depending on the product), shipping and import fees, Amazon seller account fees (£25 per month professional plan), product photography, initial advertising spend, and packaging design.
Amazon FBA is one of the more capital-intensive online business models. The inventory purchase alone represents a real financial commitment, and the learning curve on product research and listing optimisation is steep.
The honest warning: Amazon can remove your listing, change its algorithm, or allow competing sellers to undercut you at any point. The capital risk is real and asymmetric in the early stages.
Freelancing
Realistic startup cost: £0 to £200
The model: sell a skill to clients in exchange for project fees or a retainer.
What you actually need to pay for: very little to start. A basic website or portfolio page (£10 to £50), potentially software specific to your skill (a design tool, a writing tool, a development environment, many have free tiers), and time to land your first clients.
Freelancing is the closest thing to genuinely free to start among the main online income models. If you already have a skill that people pay for, writing, design, development, bookkeeping, video editing, you can start pitching for clients with essentially no upfront cost.
Where costs escalate: Once you’re earning consistently, paid tools, a professional website, and accounting software become worth the investment. The early stage genuinely doesn’t require them.
Local Lead Generation
Realistic startup cost: £100 to £500
The model: build websites that rank in Google for local service searches, forward the leads to local businesses, and charge a monthly fee.
What you actually need to pay for: domain names (£10 to £15 each), hosting (one hosting account can serve multiple sites, so £5 to £15 per month), and time to learn SEO and build the sites.
The model scales well because the cost per additional site is low once you have hosting and know what you’re doing. The investment is more time than money, particularly in the early stages.
Where costs escalate: If you want to speed up the ranking process with link building campaigns or content writers, costs rise. But the model is genuinely low-cost to get started compared to paid traffic models.
Content Creation (YouTube / Podcast / Newsletter)
Realistic startup cost: £100 to £1,000
The model: build an audience through content, monetise through advertising, sponsorships, affiliate links, or your own products.
What you actually need to pay for: depends heavily on the medium. A YouTube channel can be started on a smartphone, no additional equipment required to test the concept. A podcast needs a decent microphone (£50 to £150). A newsletter is essentially free to start through platforms like Beehiiv or Substack.
The real cost is time, consistently producing content for months before an audience builds and before monetisation produces meaningful income.
Where costs escalate: Professional equipment, editing software, video production, and paid newsletter tools all add up if you’re scaling. Starting with minimal equipment and upgrading as revenue allows is the sensible approach.
Digital Products (Courses, Ebooks, Templates)
Realistic startup cost: £200 to £1,000
The model: create a digital product once, sell it repeatedly without per-unit production costs.
What you actually need to pay for: platform fees (Gumroad, Teachable, Podia, ranging from free tiers to £30 to £50 per month for paid plans), potentially recording equipment if creating video content, and time to create the product.
The honest warning: The real cost of digital products isn’t the platform, it’s the audience you need to sell to. Without an existing audience or a paid traffic budget, a digital product has no buyers regardless of its quality.
The Hidden Cost Nobody Talks About
Every model above has one cost in common that doesn’t show up on any list of startup expenses: the cost of your time.
If you spend twelve months building a content affiliate site before it generates income, that’s twelve months of effort with no financial return during that period. If you’re employed, that time cost is manageable, you’re building the site alongside existing income. If you’re relying on the online business to replace income urgently, twelve months without returns is a real financial problem regardless of how low the startup costs are.
The most expensive version of any online business is one that takes longer than expected to generate income while you’re depending on it to pay your bills. Factor your runway, how long you can sustain yourself without income from the new business, into every model you consider.
The Realistic Bottom Line
| Model | Startup Cost | Time to First Income |
|---|---|---|
| Freelancing | £0 to £200 | 1 to 4 weeks |
| Local Lead Generation | £100 to £500 | 3 to 9 months |
| Affiliate Marketing (content) | £50 to £300 | 6 to 18 months |
| Content Creation | £100 to £1,000 | 6 to 18 months |
| Digital Products | £200 to £1,000 | Depends on audience |
| Dropshipping | £500 to £3,000 | 1 to 6 months |
| Affiliate Marketing (paid traffic) | £1,500 to £5,000 | 1 to 6 months |
| Amazon FBA | £2,000 to £10,000 | 3 to 12 months |
None of these are free. All of them are achievable with realistic planning. The model that works best for you depends on how much capital you have available, how much time you can invest, how urgently you need income, and which approach you’re willing to stick with through the inevitable slow early phase.
Frequently Asked Questions
Can you really start an online business with no money? Freelancing comes closest, if you have an existing marketable skill, you can start pitching clients with essentially zero startup cost. All other models have real costs attached, even if those costs are primarily time rather than money.
What is the cheapest online business to start? Freelancing requires the least capital. Local lead generation has low startup costs compared to models requiring ad spend. Content affiliate marketing requires some minimal hosting and domain costs but is otherwise low capital in the early stages.
How much should I budget for my first year? For a content-based business (affiliate site, YouTube channel, newsletter): £500 to £2,000 covering tools, hosting, and basic equipment. For a paid traffic or ecommerce business: £3,000 to £10,000 to run properly through the testing and optimisation phase.
Should I start a side business before quitting my job? For most models, yes, especially those with a longer runway to first income. The pressure of needing immediate returns from a business that takes six to twelve months to generate them significantly increases the likelihood of making poor decisions.
