What Is the Real Margin of a Digital Product After Platform Fees?

You sell a course for $997 on Hotmart. The student pays, the system confirms the sale, and you celebrate nearly a thousand dollars. But how much of that amount actually hits your pocket? The answer is often uncomfortable: between 20% and 45%, depending on your cost structure.

Let’s open the hood and calculate, number by number, the real margin of a digital product sold on the main Brazilian platforms.

The Illusion of Gross Revenue

Gross revenue is the number that appears on your dashboard. It’s the number gurus show in their stories. But it hides a cascade of deductions that erode your margin.

For a $997 sale, here is what happens before you see a single cent:

Fees per Platform

Each platform has a different fee structure. Let’s compare the three main ones for a $997 sale:

Hotmart:

Platform fee: 9.9% + $1 = $100.70
Net platform value: $896.30

Kiwify:

Platform fee (basic plan): 8.99% = $89.63
Net platform value: $907.37

Monetizze:

Platform fee: 9.9% = $98.70
Net platform value: $898.30

The difference between platforms seems small for one sale. But at 100 sales per month, the difference between Hotmart and Kiwify is approximately $1,107 per month — $13,284 per year.

The Cost Layers No One Tells You About

Platform fees are just the first layer. Let’s continue the cascade for a typical operation selling 80 units per month at $997.

Monthly Gross Revenue: $79,760

Layer 1 — Platform Fees (using Hotmart):

9.9% + $1/sale = -$7,976
Net after platform: $71,784

Layer 2 — Refunds:

Average rate of 8% = -$6,381
Net after refunds: $65,403

Layer 3 — Affiliate Commissions (if applicable):

40% of sales via affiliates (32 sales), 40% commission = -$12,762
Net after affiliates: $52,641

Layer 4 — Paid Traffic:

Monthly investment in Meta Ads: -$15,000
Google Ads: -$3,000
Net after ads: $34,641

Layer 5 — Tools and Infrastructure:

Email marketing (ActiveCampaign): -$500
Video hosting (Vturb/Panda): -$250
Members area: -$200
Sales pages: -$150
Other tools: -$400
Total tools: -$1,500
Net after tools: $33,141

Layer 6 — Team:

Student support: -$2,500
Video editor (freelance): -$1,500
Traffic manager (if outsourced): -$3,000
Total team: -$7,000
Net after team: $26,141

Layer 7 — Taxes:

Simples Nacional (effective rate ~10%): -$7,976
Net Profit: $18,165

The Real Margin

From $79,760 in gross revenue, $18,165 remains. The real net margin is 22.8%.

This means that for every $997 sold, your real profit is approximately $227. Not $997. Not $897 (post-fee). $227.

How Margins Change Based on Product Price

The real margin varies drastically depending on the product's price point. See the comparison:

$97 Product (e-book or mini-course)

Platform fees take a proportionally larger bite (the fixed $1 fee weighs more)
CAC must be very low for the product to be viable
Typical margin: 10% to 20%
Profit per sale: $9.70 to $19.40

$497 Product (intermediate course)

Similar proportional fees
More room to invest in traffic
Typical margin: 18% to 30%
Profit per sale: $89.46 to $149.10

$2,997 Product (mentorship or premium course)

Platform fees are diluted
Generally lower volume, higher qualification
Typical margin: 30% to 45%
Profit per sale: $899.10 to $1,348.65

The lesson is clear: the higher the price point, the higher the percentage margin. This is why so many digital creators are migrating to mentorships and high-ticket programs.

The Invisible Costs That Destroy Margins

Beyond the obvious costs, there are expenses that rarely make it into the calculation:

Your Time

If you spend 40 hours a week on the business and profit $18,000 a month, your "hourly wage" is $112.50. That sounds good until you consider you could earn $150/hour as a consultant using the same skills.

Opportunity Cost of Refunds

When a customer requests a refund, you don't just lose the sale value. You lose the CAC invested to acquire that customer, and on many platforms, the processing fee is not returned.

Payment Defaults and Installments

Bank slips (boletos) have a conversion rate between 30% and 60%. Installment plans via third-party providers charge additional fees. Sales that appear as "pending" may never actually materialize.

How to Improve Your Real Margin

There are basically four levers to improve your margin:

Reduce CAC: Improve creatives, sales pages, and conversion funnels to spend less per sale.
Reduce Refunds: Align expectations in the sales promise and improve the student experience.
Increase Average Ticket: Create upsells, order bumps, and premium versions.
Create Recurring Revenue: Subscriptions and paid communities dilute CAC over time.

But to optimize any of these levers, you first need to know your real numbers.

From Gross Revenue to Real Margin

The problem with calculating all of this manually is that it requires crossing data from multiple sources: sales platforms, ad managers, cost spreadsheets, and accounting. Most people give up in the first month.

Groware connects directly to Hotmart, Kiwify, Monetizze, Stripe, and Asaas to automatically calculate your real net revenue, already deducting fees, refunds, and commissions. Combined with acquisition data, you see your real margin per product, per channel, and per period — no spreadsheets, no manual errors.

Because the number that matters isn't how much you bill. It's how much is left.
