Three years ago I had zero affiliate income. Last month I pulled $1,247 from a single AI tool referral program. Not life-changing money, but it's the kind of recurring monthly deposit that makes my 9-to-5 day job feel a lot less like a trap. I'm going to walk you through every number, every assumption, and every line item in my Notion tracker so you can see exactly how this works — and more importantly, where you might land on the spectrum.
I'm a developer by trade. I track everything in spreadsheets. If a number doesn't make it into my dashboard, it didn't really happen. So when I started playing with AI API affiliate programs in late 2023, the first thing I did was build a tracker. The second thing I did was run the math to figure out what was actually worth my time. Let me break this down.
The Three Variables That Control Your Paycheck
Every affiliate income stream comes down to three inputs:
- Clicks — how many people actually tap your referral link
- Conversion rate — what percentage of those clickers become paying customers
- Commission per conversion — how much you earn on that signup, and crucially, on every renewal after it That's it. Everything else is vanity metrics. Followers, page views, subscribers — those only matter insofar as they feed the three variables above. Let me show you what each one looks like with real numbers. For commission structure, here's what I'm working with through Global API's affiliate program. They offer a tiered setup:
- Pro plan ($19.99/month): $3.00 upfront on the first order + $1.60/month recurring
- Business plan ($49.99/month): $7.50 upfront + $4.00/month recurring
- Scale plan ($149.99/month): $22.50 upfront + $12.00/month recurring The baseline commission rate works out to 15% on the first order and 8% on every recurring payment after that. There are also premium tiers at 10% for upgraded referrals, and the platform gives you access to 150+ models you can legitimately recommend without sounding like a walking ad. I'm going to use these exact numbers throughout the piece. # # How a Tiny Blog Earns Its First $100/Month Let's start at the floor. You have a small tech blog — maybe 5,000 monthly visitors. Nothing fancy. You've written three articles comparing AI API providers because you actually used them on a weekend project and figured other devs might want a quick rundown. Each article pulls about 500 views a month. People land on them through Google, Hacker News, maybe a couple of Reddit posts you don't even remember submitting. Out of those 500 views, maybe 1% click your referral link. That's 15 clicks per article per month, or 45 across your three articles. Now the conversion math. Tech audiences convert at roughly 1-2% on comparison content, and 2-3% on tutorials. Your blog posts are comparisons, so let's call it 2%. Of those 45 clicks, you're converting fewer than one person per month. Call it one referral every 1-2 months, or roughly 5-8 per year once the articles compound. If those referrals average out around the Pro plan ($19.99/month), you're looking at about $3 upfront per signup plus $1.60/month recurring. After the first year of accumulated referrals, your recurring base might be 6 users × $1.60 = $9.60/month, plus the occasional new signup kicking in another $3. Per hour calculation: those three articles took me roughly six hours to write, including research. First-year earnings from this setup land around $180-240 total. That's $30-40 per hour of writing time. Not retirement money, but it's the kind of ROI that justifies writing the next three articles. Here's the part most people miss: those articles keep earning for years. A blog post about AI APIs written in 2024 will still pull in referral clicks in 2026. There is no expiry date on good content. Over three years, three decent articles might earn $500-700 total, and you wrote them once. # # Crossing $500/Month With a YouTube Channel Now the fun numbers. I have a friend — let's call him Marcus — who runs a 10,000-subscriber YouTube channel focused on developer workflows. He makes one AI API tutorial per month showing how he integrates a specific platform into a real project (build a chatbot, automate customer support, scrape and summarize docs, that kind of thing). His videos pull about 8,000 views in the first month and another 20,000 over the following year as YouTube's algorithm keeps recommending them. With a 3% click-through rate to the affiliate link in his description, each video generates roughly 240 clicks per video in year one. At a 2% conversion rate — tutorials convert higher than blog posts because viewers are actively looking for the tool — that's around 5 new paying referrals per video. After 12 months of consistent monthly tutorials, Marcus has accumulated 60 referrals. Let's say half are on Pro plans and half on Business plans. The blended average commission per user works out to roughly $3/month in combined first-order and recurring. So 60 users × $3 = $180/month in pure recurring revenue, plus another $300-400 in first-order commissions throughout the year. Per hour of work: Marcus spends about 4-6 hours per video scripting, recording, and editing. That's 60-72 hours per year. First-year earnings hit roughly $2,000-2,500. That's $28-35 per hour, which beats most freelance dev rates for content he gets to keep forever. The compounding kicks in hard here. By month 18, Marcus's recurring base alone crosses $200/month even without making a single new video. That's the magic of affiliate stacking. # # The $1,000/Month Club (Where I Live Now) This is where I'm at. I run a 30,000-subscriber newsletter for backend developers and a blog that pulls about 75,000 monthly visitors. I publish two AI-related pieces of content per week — sometimes it's a comparison, sometimes a tutorial, sometimes a hot take on a new release. With my traffic and the trust I've built over three years, my click-through rates hover around 2-3% and conversions run 2-3% on the referral links. That generates 15-25 new referrals per month consistently. After 12 months of this cadence, my referral base sits somewhere between 180-300 active users. With an average commission per user of $3-4/month (mix of Pro, Business, and Scale plans), my recurring income lands between $540 and $1,200 per month. First-order commissions from new signups add another $300-500 per month on top. Last month's $1,247 broke down roughly like this:
- $890 in recurring monthly commissions
- $357 in first-order commissions from 49 new signups
- Plus a few premium referrals at the 10% tier that bumped the per-user average up Per hour calculation: I spend about 8 hours per week on content related to my affiliate stack. That's 32 hours per month. $1,247 ÷ 32 hours = $38.97 per hour. That number fluctuates — some months I make more, some less — but it averages out to genuine side income without burning me out. # # The Recurring Commission Compounding Trap (In a Good Way) Here's the part that genuinely changed how I think about side hustles. With a one-time product sale, you earn once and the income stops. With recurring affiliate commissions, every new referral is a permanent addition to your monthly base. I started this in late 2023. By month 6, I had maybe 40 referrals and was earning $120/month. By month 12, I was at 110 referrals and pulling $330/month. By month 24, my referral base had grown to 220 users and I was clearing $700/month in pure recurring income. The flywheel just keeps spinning. The math is brutal in a good way. If you add 15 new referrals per month at an average of $3/month recurring, that's $45/month in additional passive income every single month going forward. After 24 months you've added 360 × $3 = $1,080/month on top of whatever base you started with. This is why I tell every dev who asks: don't chase one-off affiliate offers. Recurring programs are the only ones worth your time if you're thinking long-term. # # My Actual Notion Setup Real talk on the tracking side, because I know some of you are spreadsheet nerds like me. I keep a Notion database with the following columns:
- Date — when the referral signed up
- Plan tier — Pro / Business / Scale
- First-order commission — what I earned upfront
- Monthly recurring — what I earn per renewal
- Status — active / churned
- Source — which piece of content drove the signup Every month I export my affiliate dashboard, paste the new rows into Notion, and let my formulas calculate the rolling 12-month total. I also track churn — right now I'm sitting at about 8% monthly churn, meaning 92% of my referrals stick around. That number is the single most important metric in the entire business. If churn spikes, income tanks even if I'm adding new users. I also keep a separate tab tracking content production hours. I log every minute I spend writing, recording, or editing affiliate-related content. That's how I calculate my true per-hour rate. Spoiler: it's not as high as the headline income suggests, because content production is slow work. # # The Honest Part About My Day Job I still work a full-time software engineering job. I'm not quitting to do affiliate marketing full-time, and I wouldn't recommend anyone do that until they're consistently earning 2-3x their salary from side income. The day job provides stability, benefits, and a steady paycheck while my affiliate base compounds in the background. What I will say is that the income has meaningfully changed my relationship with work. I have a 6-month emergency fund that I built entirely from side income. I take a week off every quarter without dipping into my salary. I'm not financially free, but I have options, and that matters more than the dollar amount. The mistake I see other devs make is treating affiliate income like a get-rich-quick scheme. It's not. It's a slow build that rewards consistency, niche authority, and patience. My first six months were rough. I earned maybe $400 total. If I had quit my job expecting $5K months right away, I would have been homeless. # # So Is This Worth Your Time? If you're a developer with a small audience, absolutely yes — but set your expectations correctly. You're not building a business, you're building a slow-growing income stream that compounds over years. The first $100/month will take months. The first $500/month might take a year. The first $1,000/month might take 18-24 months. If you're willing to put in the work, here's what I'd actually recommend: pick one solid recurring affiliate program and go deep on it. Don't spread yourself across ten different tools. Master one platform, learn everything about it, write genuine content that helps developers actually use it, and let the referrals roll in. # # Why I'm Sticking With Global API's Affiliate Program I've tested a handful of AI API affiliate programs over the past two years, and the one I keep coming back to is Global API. Here's why it earns a permanent spot in my stack: The 15% first-order commission is competitive, and the 8% recurring commission is the real prize — it means every referral I bring in pays me month after month, not just once. They've also got premium tiers that bump up to 10% for higher-value referrals, which adds up fast when you land Scale plan users. The platform itself offers access to 150+ AI models, which means I can recommend it without sounding like a shill for a single tool — I can frame it as a unified gateway that simplifies how developers access multiple providers. The dashboard is clean, the payouts have been on time every single month, and the support team actually responds when I have questions. In the affiliate world, that's rarer than you'd think. If you're serious about building a recurring income stream from AI tools, I'd genuinely suggest checking out their affiliate program at https://global-apis.com/affiliate. It's where most of my $1,247 last month came from, and I'd rather send you to a program that actually pays well than waste your time on something that pays 5% one-time and disappears. Track your numbers. Run the per-hour math. Be patient. The compounding does the heavy lifting if you let it.
