Selling a digital product at $97 feels like high-margin business — until you account for platform fees, payment processing, refunds, and taxes. The gap between gross revenue and what you actually keep is often 25–45% of the sale price. Here's how to calculate your true net margin before you build your pricing strategy around wrong assumptions.
True Cost of Selling Digital Products
Every digital product sale involves costs that come before you see a cent:
- Platform fee — the percentage the marketplace takes
- Payment processing fee — credit card and gateway charges
- Refund rate — the percentage of sales that get reversed
- VAT/GST — if selling to EU or Australian customers (if applicable)
- Income tax — your marginal tax rate on net profit
The formula:
Net per Sale = Sale Price × (1 - Platform Fee) × (1 - Payment Fee) × (1 - Refund Rate) × (1 - Tax Rate)
Platform Fee Comparison
| Platform | Fee Structure | Effective Fee on $97 Sale |
|---|---|---|
| Gumroad | 10% | $9.70 |
| Teachable (Basic plan) | 5% + $1/month | ~$5.00 |
| Teachable (Pro plan) | 0% | $0 |
| Podia | 0% (subscription only) | $0 |
| Shopify + Digital Downloads | 2.9% + 30¢ (payment only) | $3.12 |
| Kajabi | 0% (subscription only) | $0 |
| Udemy | 37–63% | $36–$61 |
| Amazon KDP (ebooks) | 30–35% | $29–$34 |
Udemy's fees look extreme, but their marketplace traffic can be worth the cut for new creators without an existing audience. Platforms with 0% fees charge monthly subscriptions ($29–$199/month), so they only make sense once you hit a monthly revenue threshold.
Break-even calculation for Teachable Pro ($119/month):
Sales needed to break even vs Gumroad =
Monthly fee ÷ Fee savings per sale
= $119 ÷ ($9.70 - $0) = 13 sales/month
Above 13 sales/month, Teachable Pro is cheaper than Gumroad.
Calculating Net Margin Per Sale
Full worked example — $97 Notion template bundle on Gumroad:
| Item | Calculation | Amount |
|---|---|---|
| Sale price | — | $97.00 |
| Gumroad fee (10%) | $97 × 0.10 | −$9.70 |
| After platform fee | $87.30 | |
| Payment processing (2.9% + 30¢) | $87.30 × 0.029 + $0.30 | −$2.83 |
| After processing | $84.47 | |
| Refund reserve (3%) | $84.47 × 0.03 | −$2.53 |
| After refunds | $81.94 | |
| Income tax (25% marginal rate) | $81.94 × 0.25 | −$20.49 |
| Net per sale | $61.45 |
The effective margin is 63.4% — not the 90%+ creators often assume for digital products.
The Refund Rate Factor
Refund rates vary significantly by product type and how clearly expectations are set:
| Product Type | Typical Refund Rate |
|---|---|
| Notion templates | 1–3% |
| Online courses (30-day guarantee) | 5–12% |
| eBooks | 2–5% |
| Software/tools | 3–8% |
| Coaching programs | 8–15% |
A 10% refund rate on a course business doesn't just reduce revenue by 10% — it also means more payment processing fees, more customer service time, and potential issues with payment processors if rates exceed 1% of total volume (PayPal and Stripe can restrict accounts with high chargeback rates).
Break-Even Volume Calculator
To cover a fixed monthly cost (like a platform subscription or ad spend):
Break-even sales = Fixed monthly cost ÷ Net per sale
If you spend $500/month on ads and net $61.45 per sale:
Break-even = $500 ÷ $61.45 = 9 sales
Every sale beyond 9 is pure profit against that ad spend.
Pricing Strategy: Premium vs Volume
High margin isn't always better than high volume. Compare two pricing options for the same product:
| Strategy | Price | Net Margin | Monthly Sales | Monthly Net |
|---|---|---|---|---|
| Premium | $197 | 58% → $114 | 10 | $1,140 |
| Volume | $27 | 52% → $14 | 120 | $1,680 |
The $27 volume strategy generates more revenue here — but requires 12× more sales. For creators without large distribution channels, a lower volume of higher-ticket sales is usually more achievable.
The sweet spot for most solo creators is $47–$197. Below $47, the fixed processing fee ($0.30) becomes a meaningful percentage, and the purchase feels low-stakes enough for buyers to request refunds. Above $197, buyers want more contact and assurance, increasing customer service burden.
Stacking Revenue Streams
Because digital products have near-zero marginal cost, adding upsells dramatically improves effective margin per customer:
Revenue per Customer = Core Product + Upsell Rate × Upsell Price
If 20% of $97 buyers take a $47 template pack upsell:
Avg revenue per customer = $97 + (0.20 × $47) = $106.40
That 9.7% increase in average order value flows almost entirely to profit since there's no additional platform fee percentage beyond what you already pay.
The most profitable digital product businesses combine reasonable per-unit margins (40–65% net) with consistent acquisition, low refund rates, and upsell sequences — not by trying to squeeze margin from any single price point.
