> Enter your price, expected sales, the platform fee and the affiliate commission you offer. See what you really keep.

## How the calculator works

For every sale:

- **Platform fee** = price × fee %.
- **Affiliate commission** = price × commission %, only on sales an affiliate brought in. It comes out of your share.
- **You keep** = price − platform fee − affiliate commission.

The monthly total uses your estimate of how many sales come through affiliates. This is the same split AiBio.Store uses for member stores. Everything is calculated in your browser.

## Typical platform fees to compare

| Platform type | Typical fee |
|---|---|
| Marketplaces with a discovery page | Often 10%–30% on marketplace sales |
| Creator storefronts | 0%–10% plus card processing |
| AiBio.Store | Free plan 20%; paid plans 15%, 10%, 7%, 5%, 3%; crypto checkout |

Check each platform's current pricing page before you decide. Fees change.

## Should you offer an affiliate commission?

A commission lowers what you keep per sale but can multiply the number of sales, because other people promote your product for you. A common starting point for digital products is 20%–40%. Try the calculator: raise the commission and the share of affiliate sales, and see where your monthly total goes up.

## FAQ

### How much can I earn selling digital products?

It depends on price, audience and how many people promote it. Many first products sell a handful of copies a month. Use realistic numbers in the calculator, not best cases.

### Where does the affiliate commission come from?

From your share of the sale, after the platform fee. The platform fee does not change.

### Can buyers pay in crypto?

On AiBio.Store, yes: buyers pay the exact price in Litecoin or Bitcoin and get the product as soon as the payment confirms.
