# Collecting Seller Fees

Seller Payouts Hero
Finix allows you to monetize your payments by charging `Fees` to your sellers.

Fees are the revenue you make for processing transactions. You can also charge Fees for specific events like disputes and ACH returns.

Finix offers a number of ways to charge Fees to your sellers.

## 1.) Calculating fees with Merchant Fee Profiles

### Available pricing strategies

Finix's Merchant Fee Profiles take care of the heavy lifting and supports many different pricing strategies and fees.

#### Interchange plus

Your sellers pay the interchange rate set by the issuing banks plus a markup you can charge on top.

#### Interchange plus and dues & assessments

Your sellers pay the interchange rate as well as separate pass-through of card network fees (dues and assessments). Finix provides many of these Dues and Assessments at a Transaction level.

#### Blended pricing

Transactions are charged a single flat rate (e.g. 2.90%+ 30 cents). There are additional features to charge different card brands (e.g. Visa, MasterCard, Discover, and Amex) and payment methods a different rate.

### All available fees

Finix has 60+ fee options to monetize your payments. To see all available fees, see our [Fee Profile guide](/guides/platform-payments/monetizing-payments/merchant-fee-profiles).

## 2.) Calculating fees dynamically

Some platforms have dynamic pricing strategies that depend on a number of factors such as promotions, concessions, and other criteria.

In this case, Finix makes it easy to be able to support these use cases. You can use our /transfers API to pass in a `supplemental_fee` that can be varied on each transaction.

For additional information, see our [Dynamically Calculating Fees Guide](/guides/platform-payments/monetizing-payments/calculating-fees-dynamically).

## 3.) Splitting a transaction to collect a portion of revenue

Some platforms choose to take a small portion of every payment. Finix supports this using our Split Transactions functionality. To learn more about Split Transactions, see the [Split Transactions guide](/guides/online-payments/payment-features/split-transactions).
