Payhip vs Ko-fi vs itch.io: the fee math on a $6 download
Every "where should I sell my digital products" post compares headline percentages. The headline percentage is the smallest number in the equation. Here is the arithmetic on a real $6 download, with the assumptions written down so you can redo it with your own.
The three platforms, as listed in November 2026
| Platform | Platform fee | Monthly fee | What the fee buys |
|---|---|---|---|
| Payhip (free plan) | 5% per sale | $0 | Hosted checkout, file delivery, EU VAT handling, PayPal/Stripe payouts |
| Ko-fi (Standard) | 5% on shop sales, memberships, commissions | $0 | Shop, tips, memberships, commission requests, one page |
| Ko-fi Gold | 0% | $12 | The same, without the per-sale cut |
| itch.io | 10% by default, adjustable by the creator | $0 | Game-adjacent storefront, devlogs, pay-what-you-want pricing |
All three also pass through payment-processor fees. The platform cut is not the only deduction, and the processor fee is often larger than the platform fee on a small sale.
The worked example: one $6 sale
Assumption used below: 3.4% + $0.30 processing, which is a common card/PayPal rate for a cross-border sale. Your rate depends on your country, the buyer's country, and the payment method. Substitute your own number.
| Line | Payhip free | Ko-fi Standard | Ko-fi Gold | itch.io (10%) |
|---|---|---|---|---|
| Buyer pays | $6.00 | $6.00 | $6.00 | $6.00 |
| Processing (3.4% + $0.30) | -$0.50 | -$0.50 | -$0.50 | -$0.50 |
| Platform fee | -$0.30 | -$0.30 | $0.00 | -$0.60 |
| You keep | $5.20 | $5.20 | $5.50 | $4.90 |
The spread between the best and worst outcome is $0.60, or 10% of the sale. That is not nothing, but it is not the number that decides whether the store works.
When the monthly fee wins
Ko-fi Gold saves $0.30 per $6 sale. At $12 per month, it breaks even at 40 sales per month - about $240 of shop volume. Below that, the free plan is cheaper. Above it, Gold is cheaper and the gap widens linearly.
Payhip's paid tier works the same way: a flat monthly fee only makes sense once the 5% cut exceeds it. Run your own volume through the formula before upgrading. A store doing $200 per month should not be paying a monthly fee to save $10.
The number that actually decides revenue
Suppose the store gets 1,000 product-page views in a month. At a 1% conversion rate that is 10 sales, or about $52 net at $5.20 each. At 5% it is 50 sales, or about $260. The conversion difference is worth 5x. The platform-fee difference is worth 10%.
This is the part the comparison posts leave out. Moving from a 10% platform to a 5% platform improves the outcome by about 5%. Doubling traffic or doubling conversion doubles it. Fee optimisation is a rounding error until the traffic exists; after that, it is worth ten minutes a year.
What I would tell a first-time seller
- Pick the platform that pays out in your country without a workaround. A 0% fee you cannot withdraw is a 100% fee.
- Put the same product on two platforms, not five. Every additional listing is maintenance you will stop doing.
- Price under $10 until you have proof people will pay at all. A $6 sale with a 5% fee is a better signal than a $60 sale that never happens.
- Write the licence and refund terms on the listing, not in an email after the sale.
- Measure views and conversion separately. One number tells you nothing.
