I Made $1,243 Last Month Promoting AI Tools — Here's the Exact Breakdown

#makemoneyonline #ai #sidehustle #passiveincome

Honestly, six months ago I added a new tab to my Notion dashboard labeled "AI Affiliate Side Hustle." I was tired of guessing whether my content was actually making money, so I started logging every click, every signup, every commission payment down to the cent. What follows is everything — the wins, the duds, and the math I wish someone had shown me before I started.
Quick context: I work a 9-to-5 as a backend developer, write a small dev blog on weekends, and run a barely-active newsletter. I'm not a guru. I'm a spreadsheet guy who treats side income like a side project.

Why I Picked This Niche in the First Place

Every dev I know is building something with AI right now. Slack channels are full of people wiring up LLM endpoints, building RAG pipelines, prototyping chatbots. So when I started looking at affiliate programs, AI APIs were an obvious fit — I was already writing about them for my own learning.
I tested three programs before settling on Global API. Two reasons stood out:

  1. Their model catalog has 150+ models under one roof, which means I'm not pigeonholed into recommending one vendor.
  2. The commission structure actually makes sense for affiliates: 15% on the first order, 8% recurring on every renewal after that, and a bumped-up 10% premium rate for top performers. Most AI affiliate programs I looked at offered a one-time bounty and forgot about you. Before I get into scenarios, let me show you exactly how I think about the money. # # The Three-Variable Formula I Use Every Time Every affiliate income stream breaks down into three numbers:
  3. Clicks — how many people actually hit your referral link
  4. Conversions — what percentage of those clicks become paying users
  5. Commission per conversion — what you earn when someone signs up That's it. If you can't move one of those three levers, your income stays flat. Let me give you the Global API commission table I keep pinned in my tracker, because this is what every calculation hinges on: | Plan | Monthly Price | First-Order Commission (15%) | Recurring Commission (8%) | |------|--------------|------------------------------|---------------------------| | Pro | $19.99 | $3.00 | $1.60/month | | Business | $49.99 | $7.50 | $4.00/month | | Scale | $149.99 | $22.50 | $12.00/month | The premium tier bumps first-order to 10% if you hit volume thresholds, but I'll get to that. Now — how much money you make depends entirely on your traffic source and how naturally you can weave a recommendation into content people actually want to read. # # My Real Numbers, Month by Month Here's what my Notion tracker actually shows. I'll be honest about the early months because that's where most people quit. Month 1: $0. Wrote two blog posts. Got 11 clicks. Zero conversions. Felt dumb. Month 2: $34. One person signed up for the Pro plan after reading my comparison post. That's $3.00 upfront + a few dollars of recurring accumulated over the rest of the month. Month 3: $89. Same post kept ranking. Two more Pro signups. Recurring kicked in. Month 4: $312. I published a YouTube tutorial on building a small RAG app with Global API. That single video did more than all my blog posts combined. Month 5: $678. My newsletter had a good open rate that month. One Business plan signup + four Pro renewals. Month 6: $1,243. Recurring commissions from earlier referrals compounded. A Scale plan signup from a founder who found my YouTube video. Total over six months: $2,356. Now — your numbers will depend entirely on your audience size. Let me run the same math for three different creator profiles so you can find yourself in here. # # Scenario 1: The Solo Dev With a Small Blog Let's say you're running a personal blog pulling about 5,000 monthly visitors. You write three comparison posts about AI APIs. Each post gets around 500 views per month once it's indexed. Here's the math per article:
  6. 500 views × 1% click-through rate to your referral link = 5 clicks per article per month
  7. 15 clicks total across three articles
  8. 2% conversion rate (typical for comparison content) = ~0.3 new signups per month That's roughly 3-4 new referrals per year. At an average blended commission of about $5 per referral per month (mixing first-order payouts and recurring), you're looking at $15-20/month once your referral base matures. I know — that sounds tiny. But here's why it matters:
  9. Writing those three articles probably took you six hours total.
  10. Over three years, those same posts could generate $500-700 in cumulative commissions.
  11. That's an effective rate of $100+ per hour of work. The trick is that the income shows up slowly, then sticks around. I treat this kind of content like buying a bond — slow to mature, but reliable once it does. # # Scenario 2: The YouTuber Building a Niche Channel Picture this: you've got 10,000 subscribers and you publish one AI API tutorial per month. Each video pulls 8,000 views in the first month, then trickles another 20,000 views over the following year through search and suggested traffic. Per video:
  12. 8,000 first-month views × 3% CTR (tutorials convert better because viewers are actively looking for the tool) = 240 clicks
  13. 20,000 long-tail views × 3% CTR = 600 additional clicks over the year
  14. 2% conversion rate = ~5 new referrals per video in the first month alone, more trickling in over time Now multiply that across a year of monthly uploads:
  15. 12 videos × 5 new referrals = 60 referrals in your base
  16. Average commission per user (mix of Pro and Business plans): ~$3/month recurring
  17. Monthly recurring income once mature: ~$180
  18. First-order commissions from new signups each month: ~$25-30 First-year total: roughly $2,000-2,500. Here's where it gets fun — that $180/month recurring doesn't go away. Month 13, you're still collecting it. Month 24, same thing. YouTube tutorials have a beautiful compounding effect because old videos keep getting discovered. # # Scenario 3: The Established Creator With a Real Audience Now the big numbers. Imagine you've got a 30,000-subscriber newsletter plus 75,000 monthly blog visitors. You're publishing two AI-related pieces of content per week, your name carries weight in the dev community, and people trust your recommendations. With that authority, your click-through rates climb to 2-3% and conversions land at 2-3% because your audience is pre-sold on your taste. You're pulling in 15-25 new referrals per month consistently. After a full year:
  19. 180-300 users in your referral base
  20. Average commission per user: $3-4/month (mix of plans)
  21. Monthly recurring commissions: $540-1,200
  22. First-order commissions from each month's new signups add another $300-500 Total annual revenue: $8,000-15,000. That's "this is now a meaningful side income" territory. That's a car payment. That's a chunk of rent. That's "I can take my spouse to dinner without checking my bank account first" money. # # The Part Nobody Talks About: Compounding Here's what flipped my mindset. I used to think of affiliate income as a series of one-off payouts. Each signup feels like a small win, you collect the commission, and then what? You're back to zero. That's wrong. Recurring commissions turn each signup into a tiny annuity. Let me show you the compounding math using round numbers. Say you refer 10 new users per month consistently for a year. By month 12, you have 120 users in your base. If each user generates $3/month in recurring commissions, that's $360/month — and it's not going anywhere as long as those users keep their subscriptions. Push that out two years. You keep referring 10 per month. Now you've got 240 users. Your monthly recurring is $720. Year three: 360 users, $1,080/month. The growth isn't linear — it's stacked. This is why I told you my Month 6 was $1,243. Half of that was old referrals still paying me their $1.60-$12 monthly commissions. The other half was new signups from content I'd published months earlier. A referral you landed in January might still be paying you in December. That's the leverage. # # How I Track All of This Without Going Crazy I mentioned Notion earlier, but let me be specific because a few people have asked. My setup is embarrassingly simple:
  23. A single Notion database with columns for date, referral source, plan tier, signup value, commission earned, and recurring status.
  24. A dashboard view that sums monthly commissions and breaks down first-order vs. recurring.
  25. A pinned formula block that calculates my effective hourly rate based on hours spent creating content. I update it every Sunday with 10 minutes of copy-paste from my affiliate dashboard. The hourly rate column is what keeps me honest — if I'm spending 8 hours on a post that earns $40 in its first year, I need to know that. The recurring column is what keeps me motivated. Watching $12/month from a single Scale plan referral show up in my tracker 14 months after I published the video that drove it? That's the kind of number that makes you want to write another post. # # What I Do Differently Than Most Affiliate Creators A few habits that moved the needle for me, in case any of this is useful: I never bury the recommendation. The affiliate link goes in the first 200 words of any blog post and in the first 60 seconds of any video. People who scrolled past the intro weren't going to convert anyway. I only promote what I'd use myself. I have a pet project that uses Global API for embeddings and completions. When I write about it, I'm not making anything up. That authenticity converts better than any landing page trick. I treat content like infrastructure, not content marketing. Every blog post and video is a long-term asset. I'm not chasing trending topics. I'm building a library of evergreen comparisons and tutorials that will still rank in 18 months. I ignore the daily numbers. Checking my dashboard every day drove me nuts. Sunday updates only. The graph trends up over weeks, not hours. # # The Honest Part: What I'd Do Again and What I Wouldn't Would do again: Starting with Global API. Their commission structure rewards you for the long game, not just the first sale. The 8% recurring means I'm not constantly hustling new traffic to stay flat. Would skip: My first three weeks of comparison posts that were basically rewrites of someone else's comparison post. Original takes convert better. Generic listicles don't. Would've started sooner: YouTube tutorials. A single 12-minute video outperforms three blog posts of the same length, for me. Your mileage will vary, but if you're choosing between formats, start with the one your audience actually wants. # # My Day Job Perspective, Briefly I don't want to oversell this. Affiliate income from AI tools has not replaced my salary. It's not even 20% of my salary yet. But it's grown from $0 to a few hundred dollars per month in recurring income in under a year, with maybe 4-6 hours per week of effort on top of my regular job. The compounding math is what I'm betting on. If I keep this pace for another 12 months, my conservative estimate puts me at $2,000-2
