Interchange Plus Pricing

Interchange-plus pricing is a payment processing fee model that separates the card network interchange cost from the processor's markup. Instead of paying one blended rate for every card transaction, the merchant sees the underlying interchange cost plus an added processor fee.

This pricing model is common in merchant services because it can make processing costs more transparent. It can also be harder to understand than flat-rate pricing.

Interchange-plus pricing meaning

Interchange-plus pricing usually has two parts:

• interchange, which is set by card networks and paid to the issuing bank
• processor markup, which is the fee added by the processor or merchant services provider

For example, a transaction might cost the interchange rate plus 0.30 percent and 10 cents. The exact numbers vary by provider, card type, region, transaction type, and merchant agreement.

Interchange-plus vs flat-rate pricing

Flat-rate pricing charges a simple blended fee, such as one percentage plus a fixed amount per transaction. It is easier to read and forecast.

Interchange-plus pricing shows more of the underlying fee structure. Some transactions may cost less than a flat rate, while others may cost more depending on card type and risk.

The better model depends on volume, average order value, card mix, business type, reporting needs, and how much complexity the business is willing to manage.

Why interchange-plus pricing matters

Payment fees affect margin, especially for high-volume sellers, high-ticket offers, payment plans, and subscription businesses.

Interchange-plus pricing can help a business understand:

• how much card acceptance really costs
• which card types are more expensive
• whether processor markup is competitive
• how fees affect product margin
• whether a pricing change would improve net revenue

For a checkout-led business, payment cost should be viewed alongside conversion, approval rate, failed-payment recovery, refunds, and disputes.

Interchange-plus and checkout economics

A lower processing rate is not automatically better if the payment setup hurts conversion or recovery. A cheap provider that creates more declines, weaker wallet support, or messy reporting can cost more than it saves.

Checkout economics should include:

• processing fees
• payment approval rate
• checkout conversion
• average order value
• refund rate
• chargeback cost
• failed-payment recovery
• support time

Who uses interchange-plus pricing

Interchange-plus pricing is often used by businesses with enough payment volume to care about fee detail. It may be useful for sellers who process a meaningful amount of card revenue and want to compare providers more carefully.

Smaller businesses may prefer flat-rate pricing because it is easier to understand. Larger or more payment-sensitive businesses may prefer interchange-plus pricing because it exposes more of the cost structure.

What to watch for

Interchange-plus pricing can still hide costs if the agreement includes extra fees, monthly minimums, gateway fees, statement fees, chargeback fees, PCI fees, or payout fees.

When comparing payment providers, ask for the full fee schedule. The markup is only one part of the cost.
