"Free" platforms with revenue share are usually more expensive than $19/mo

"It's free to start" is a powerful pitch. Gumroad, Beacons, and a half dozen other creator platforms lead with it. The catch shows up in the fine print: the platform takes a percentage of every sale forever. 10% on Gumroad. 9% on Beacons free. 6.5% on Etsy.

Compare to a monthly fee like instxnt Pro at $19, Shopify Basic at $39, or Squarespace Commerce at $36. The monthly fee feels worse because you pay it before you have any sales. The revenue share feels better because you pay it only when money is coming in.

Above a certain monthly volume, the revenue share is dramatically more expensive. Most sellers cross that breakeven faster than they think. Here is the math, with the exact breakevens.

The simple version

For each platform, monthly cost = (revenue share %) × revenue + (monthly fee). On a fee-only platform the slope is the revenue share %; on a subscription platform the slope is zero (after the monthly fee).

At low revenue, the fee-only platforms win because the monthly fee dominates. At high revenue, the subscription platforms win because the revenue-share slope keeps eating margin while the subscription stays flat.

The breakeven point is where (revenue share %) × revenue = monthly fee. Solve for revenue.

The breakevens

Take instxnt Pro vs each common alternative:

• vs Gumroad (10%): instxnt Pro is cheaper above $190/month in revenue. Below that, Gumroad. Most sellers who care about platform fees are above that already.
• vs Beacons free (9%): instxnt Pro is cheaper above $211/month. Same story.
• vs Etsy (~10% all-in): instxnt Pro is cheaper above ~$190/month, but Etsy gives you organic discovery that instxnt does not — so the fee math is not the whole story for Etsy.
• vs instxnt Free (3%): Pro is cheaper above $633/month. If you are doing $1000+/mo, Pro is meaningfully cheaper. Below ~$600/mo, Free is fine.
• vs Stan.store ($29/mo): instxnt Pro is just cheaper. There is no breakeven — it is $19 vs $29 with similar capabilities for the storefront use case.

The breakevens are smaller than people guess. If you sell $300 of digital products in a month, you are already paying more on Gumroad or Beacons than you would on instxnt Pro. And the gap widens with every additional sale.

The psychology of why this is hard

Two things make this harder to act on than it should be:

1. Revenue share fees are invisible per-transaction.Stripe pays you the net, after fees. You see the deposit, not the cut. You have to actively pull a fee report to see what the platform took. Most people don't.
2. Monthly fees are loss-aversion-loaded.$19 feels like a real cost because you committed to it whether you sell anything or not. $19 worth of revenue share on a Gumroad sale does not feel like a cost; it feels like "a portion of your win." Identical money, different feeling.

The fix is to look at total monthly cost across both buckets, not at individual transactions. The margin calculator shows it all in one place if you want to plug in your numbers.

When "free" actually is cheaper

Below the breakeven, free-with-revenue-share platforms genuinely are cheaper. Specifically:

• You are testing and have zero traction yet. instxnt Free (3% per sale, $0/mo) wins.
• You sell rarely — like once a month, $50 a pop. The revenue share on $50 is $5; the subscription would be $19. Subscription loses for very low volume.
• You are using the platform's built-in distribution (Etsy organic search, Gumroad Discover, Beacons creator network). The revenue share is partly buying you that traffic. On a platform like instxnt where you bring your own traffic, you are paying for nothing extra.

If you fit any of those, stay free. If you do not, do the math.

The instxnt-specific take

We charge 3% on Free instead of 0% specifically because we want the upgrade incentive to be honest. If Free were truly free we would have no reason to invest in Pro features beyond the custom domain. The 3% gives both sides skin in the game: low enough that screening tests are essentially free, high enough that real volume creates a real reason to upgrade.

At the volume where the 3% becomes meaningful (around $600+/month in revenue, roughly), Pro at $19/mo is cheaper. We'd rather you upgrade and we keep getting better than have you feel exploited at volume.

Compare to Gumroad's 10%, where the platform's incentive is to keep you on the free tier forever because every sale you make pays them. Different incentive structures produce different products. The math reflects it.

The takeaway

"Free with revenue share" is the right pricing for early experiments and for platforms that bring you traffic. Above a few hundred dollars a month in revenue from your own audience, monthly subscriptions usually win on total cost, often by a wide margin.

Run your own numbers. Don't pick by feeling. The margin calculator takes about thirty seconds and either confirms what you were going to do or saves you an awkward amount of money.
