When I tell people I make a living writing online, they assume I mean one thing — articles, a paycheck, done. The reality is messier and more interesting. I have seven distinct income streams, all built on writing in some form. Some are active. Some are genuinely passive. Most took longer to build than I expected and earn more than I imagined once they got going.

Here's every side hustle for writers that actually works for me — with real numbers and honest timelines.

Platform revenue from Medium and Substack

This is where most writers start, and for good reason. Medium pays writers based on member reading time. Substack lets you charge paid subscriptions. Both are free to start and don't require building your own website or audience from scratch.

My Medium earnings have varied wildly — from $47 in a slow month to over $2,000 in months where an article went viral. The average over the past year is around $400 to $600/month. Not life-changing, but consistent enough to fund the coffee habit and then some.

Substack paid subscriptions are smaller for me right now — I'm still building that base through my newsletter. But the recurring revenue model is fundamentally different from Medium's per-article payouts. Every new paid subscriber adds to a baseline that doesn't disappear when you take a week off.

Combined, platform revenue is my most predictable income stream. It requires consistent publishing — I aim for two to three articles per week across platforms — but the work compounds. Articles I wrote 18 months ago still earn money every month.

Digital products

This is the income stream I wish I'd started three years earlier. Digital products — guides, templates, playbooks, tools — have the best economics of any side hustle for writers because you create them once and sell them indefinitely.

My current products include writing guides, SEO playbooks, and platform-specific growth strategies. Each took 40 to 80 hours to create. The best-selling one has generated over $12,000 in total revenue since launch. The worst-selling one made $340. The average is somewhere around $3,000 to $5,000 per product over its lifetime.

I sell through Payhip* — a platform that handles payments, delivery, and tax compliance for a small transaction fee. No monthly cost, no minimum sales requirement. You upload a PDF or a template, set a price, and share the link. For writers starting their first digital product, Payhip has the lowest friction of any platform I've tried.

The key insight about digital products: your newsletter and blog articles are the marketing. Every article you write that's related to your product is a potential sales funnel. An article about "how to grow on Substack" naturally leads to a link to your Substack growth guide. The content and the product reinforce each other.

Affiliate income

Affiliate marketing gets a bad reputation because most people do it badly — promoting products they've never used for commissions they barely earn. Done right, it's one of the most natural side hustles for writers because you're doing what you already do: recommending things you genuinely use.

I earn affiliate commissions from tools and platforms I actually use and write about. The commissions are modest per sale — typically $5 to $50 — but they compound over time because the articles containing the links keep getting traffic from Google months and years after publication.

Two affiliate programs that work particularly well for writers:

Payhip* pays recurring commissions for referred sellers. If you recommend Payhip in an article about selling digital products and someone signs up through your link, you earn a percentage of their transaction fees for life. It's a small amount per person, but it compounds.

SparkLoop* is a newsletter referral platform that pays you for recommending other newsletters to your audience. It also has an affiliate program for referring new newsletter creators to the platform. If you write about newsletter growth (which I do regularly), SparkLoop is a natural recommendation.

My total affiliate income: roughly $200 to $500/month. Not a primary income stream, but it requires zero ongoing work beyond the initial article. True passive income.

Newsletter sponsorships

Once your newsletter reaches a few thousand subscribers, brands will pay to be mentioned in your issues. Rates vary enormously — $25 to $500+ per mention depending on your niche, audience size, and engagement rates.

I've been selective about sponsorships. I only promote products I'd recommend anyway, and I limit sponsored mentions to one per issue. This protects reader trust, which is worth more long-term than any individual sponsorship payment.

Finding sponsors early on requires outreach — identifying companies relevant to your audience and pitching them directly. Tools like SparkLoop* can automate newsletter cross-promotions, where you earn money by recommending other newsletters to your readers. It's a lower-friction entry point into sponsorship income.

Freelance writing and consulting

Here's the side hustle most writers overlook: your published writing is a portfolio. Every article you publish demonstrates expertise. Companies that need content about topics you've written about will pay you to write for them — often significantly more per article than platform revenue.

Freelance writing rates for experienced writers with a strong portfolio range from $200 to $2,000+ per article, depending on the niche and client. B2B content (fintech, SaaS, healthcare) pays the most. Consumer content pays less but is easier to break into.

I do limited freelance work — a few projects per quarter — because my other income streams have grown to the point where I'd rather invest time in my own content. But for writers building their income streams, freelance writing is the fastest path to meaningful money. You can earn your first $500 within a month of starting, which is faster than any other side hustle on this list.

Consulting is the premium version of this. Instead of writing for clients, you advise them on their content strategy. Hourly rates of $100 to $300 are standard for writers with demonstrated expertise and a track record of results. A newsletter that positions you as an authority in a specific niche is the best consulting pipeline I've seen.

Cross-platform syndication

Write once, publish everywhere. A single article can earn money on Medium, drive subscribers on Substack, rank on Google through your blog, and generate engagement on LinkedIn. Each platform reaches a different audience, and the marginal effort of republishing is minimal compared to writing from scratch.

My syndication workflow: I write the article once. I publish it on my primary platform. Then I adapt it for Medium (adjusting for their audience), post a condensed version on LinkedIn, and share key insights on Substack Notes and X. One article, five touchpoints, five potential income streams.

The canonical link strategy is crucial here — it tells Google which version is the original, preventing duplicate content issues. I covered this in detail in my long-form writing.

Building tools for other writers

This one is less obvious but has been one of my most rewarding side hustles for writers. If you understand what writers need — because you are one — you can build tools, templates, and systems that solve real problems.

I've built writing tools, SEO guides, and workflow templates based on systems I developed for my own work. The advantage of building for writers is that you deeply understand the customer because you are the customer. You know the pain points. You know what solutions work and which are overengineered.

You don't need to be a developer. Template businesses (Notion templates, spreadsheet tools, Canva templates) require no coding. Guide businesses require only your expertise and a word processor. The barrier to entry is low. The barrier to creating something genuinely useful is higher — but that's where your experience as a writer is your unfair advantage.

Which side hustles to start first

If I were starting from zero today, here's the order I'd build income streams:

  1. Month 1-3: Start writing on Medium and/or Substack. Build a publishing rhythm. Earn your first platform revenue.
  2. Month 3-6: Start freelance writing using your published articles as a portfolio. Fastest path to $500+/month.
  3. Month 6-12: Create your first digital product based on your most popular articles. Sell it to your growing audience.
  4. Month 12-18: Add affiliate links to relevant articles. Start newsletter sponsorship outreach once you hit 2,000+ subscribers.
  5. Month 18+: Build tools or premium products. Consider consulting. These require an established audience and reputation.

The compounding effect is real. Each stream feeds the others. Articles drive traffic to products. Products build credibility for freelance work. Freelance work gives you material for articles. Newsletter growth unlocks sponsorships. It all connects.

The honest truth about multiple income streams

Building multiple side hustles for writers takes time. Real time. I didn't have seven income streams in my first year. I had one — Medium — and it paid poorly. The second stream took six months to add. The third took another four months. Each subsequent stream was easier to build because the previous ones had created an audience and a reputation.

The total income from all seven streams today is enough to live on comfortably. But the first year was a grind. If you expect to build a diversified writing income in 90 days, you'll be disappointed. If you commit to 18 to 24 months of consistent work, you'll be surprised how much is possible.

Start with one platform. Write consistently. Let the audience build. Then layer in additional streams as opportunities arise. That's not sexy advice. It's the advice that works.
