How to Earn $100 a Day Through Affiliate Marketing: The Actual Formula

Search "how to earn $100 a day through affiliate marketing" and nearly every result gives you the same move: a table claiming a $10 commission needs 15,000 monthly visitors, or that a $200 commission only needs 1,500, with no explanation of where the conversion rate inside that table came from. It's presented as fact. It's actually a guess wearing a table. The honest version of this question doesn't hide the guess; it shows you the formula and lets you plug in numbers you can actually check for your own situation, the same approach how many referrals it takes to replace your income uses for Lesso's own affiliate programme.

$100 a day is $3,000 a month, or $36,500 a year at a flat run rate. That much is just multiplication. What it takes to get there depends entirely on the shape of the commission you're earning, and "shape" here means something specific: is it a fixed amount per sale, a percentage of something recurring, or a percentage of something that only exists if the person you referred is actually succeeding? Those three shapes require completely different volumes of sales to hit the same $100.

The one formula that applies to all of them

Sales needed per month = monthly target ÷ commission per sale. That's the whole formula. Everything below is that equation applied to a specific commission structure, because "commission per sale" means something different in each one.

Flat-fee-per-sale programmes

Some affiliate programmes pay a fixed dollar amount every time someone completes an action, regardless of what that action is worth to the business behind it. beehiiv's Boosts programme is a real example: it pays a flat $1 to $3 per verified newsletter subscriber, with no percentage and no ongoing relationship to track.

Because the fee is fixed, the formula collapses to plain division, and you can build the table yourself for whatever flat fee you're actually being offered.

These five fee amounts are points on the formula, not a claim about what any specific programme pays; check the actual rate on whatever programme you're evaluating and divide $3,000 by it. The structural fact worth noticing is that a flat-fee programme is the easiest of the three shapes to plan against, because your commission per sale never moves. It's fixed the day you join, so the only variable left is how many sales you can generate, which is a traffic and conversion question, not a maths question.

Percentage-of-subscription programmes

A different shape: instead of a fixed fee, you earn a percentage of what the person you referred pays a platform, usually every month, for as long as the arrangement lasts. Teachable's Partner Program works this way, paying 30% of a referred creator's Teachable subscription for 12 months. On an $89/month plan, that's $26.70 per referred subscriber per month.

Here the formula needs one more input: the referred person's active subscription, not a one-time sale.

Active referred subscribers needed = monthly target ÷ (commission rate × subscription price).

At 30% of $89/month, $3,000 ÷ $26.70 works out to roughly 112 active referred subscribers, all paying at the same time, every month, for the programme to keep hitting $100/day. That number is the load-bearing detail most guides on this topic skip: a percentage-of-subscription commission requires you to have accumulated and be holding onto that many simultaneously active referrals, not just to have made 112 sales once. If even a handful of those subscribers cancel, the number drops immediately, and Teachable's programme stops paying on any individual referral entirely once 12 months are up, regardless of whether that subscriber is still paying Teachable in month 13. The full comparison of recurring versus one-time commission structures works through why that cap matters more than the headline rate.

Lesso's model: a percentage of net, not gross

Lesso's affiliate programme is a third shape again, and it's worth being precise about it rather than folding it into either category above. Lesso takes a 15% platform cut only when a referred creator's course actually sells, absorbs Stripe's processing fee (3.4% plus $0.30 per transaction) out of that cut rather than adding it on top, and pays affiliates 50% of what's left, Lesso's actual net. In formula terms, for a course priced at P: Lesso's net per sale is P × (0.15 − 0.034) − $0.30, and your commission is half of that.

That formula pays out differently depending on whether the referred creator sells a one-time course or runs a subscription, because "per sale" means one payment either way, whether that payment happens once or once a month.

Same formula as the sections above, computed from Lesso's actual revenue split instead of a flat fee or a subscription percentage. If a referred creator sells a one-time $79 course, that's 677 sales in a month across everyone you've referred combined, not from one creator alone. If instead a referred creator runs a $29/month subscription, the same $1.53 figure applies per subscriber per month, so 1,961 subscribers paying simultaneously would clear $100/day, the same active-subscriber requirement as the Teachable example above, just at a different rate and with no 12-month cutoff underneath it.

Worth being direct about: 677 combined sales a month, or nearly 2,000 simultaneous subscribers, is a large number for most affiliates to reach from a single programme. Lesso's commission has no cap and no expiry tied to your own ongoing effort, but that compounds an outcome that's already happening; it doesn't lower the volume the formula requires. Nobody's affiliate programme changes that arithmetic, including Lesso's, and a page that implied otherwise would be worth distrusting for the same reason the generic "$100 a day" guides are.

The input nobody can honestly hand you

Every table above answers "how many sales" once you supply a commission rate. None of them can answer "how much traffic" or "what conversion rate," because those depend on your specific audience, content, and niche, and no affiliate programme, including Lesso's, publishes an average that would mean anything applied to your situation. The generic "$100 a day" guides that cite "a typical 2% conversion rate" or claim "thousands of beginners hit this in 3 to 6 months" are stating someone else's outcome as if it were a formula input, and there's no way to verify a number like that because it was never measured for you in the first place.

What you can do instead is work backwards honestly: pick the commission shape you're actually being offered, compute your real commission per sale or per subscriber using the formulas above, divide your target by it, and then judge for yourself, using your own traffic and your own past conversion numbers if you have them, whether that many sales is realistic for what you're promoting. That's a harder answer than "yes, thousands of people do this," but it's the only one that's actually about your situation rather than a stranger's.

If you're pricing this in pounds instead of dollars

This target shows up in search overwhelmingly as a dollar figure, "$100 a day," reflecting where most of the affiliate content and programmes discussing it are based. A pound-denominated version does exist ("£100 a day"), and the arithmetic is the same shape either way: £100 a day is roughly £3,000 a month, and every formula above works identically with commission rates and prices in pounds instead. As a rough point of reference, at today's exchange rate $100 converts to about £75 (GBP/USD trading around 1.335 as of July 2026), so treat the two targets as separate numbers rather than interchangeable ones, and check what currency your specific programme actually pays in.

Where this fits with the rest of the decision

If you're still deciding which affiliate programme's commission shape to build around in the first place, the best affiliate programmes for newsletter writers and digital product reviewers compares several by what their percentage is actually a cut of, and is affiliate marketing worth it in the UK covers the broader viability question if you're weighing this against other income streams first. If a large chunk of your realistic path to $3,000 a month is likely to come from a small number of strong referrals rather than a high volume of small ones, the 80/20 rule in affiliate marketing is worth reading before you decide how to spend your time.
