Credit card processing fees can come from several parties, so a single advertised rate rarely shows the full cost. First, separate the charges into three groups: interchange, card-network assessments, and processor or provider fees.

1. Interchange fees
Interchange is part of the card-payment system. The acquiring side typically pays it to the issuing bank under network rules; merchants generally pay a broader merchant discount rather than interchange directly.
Rates vary with the card, transaction channel, merchant category, amount, and data quality. For example, a card-present sale may qualify differently from a manually entered or online payment. Merchants usually cannot negotiate the underlying network category, but accurate transaction data and timely settlement can help a sale qualify correctly.
2. Assessment or network fees
Card networks charge assessments for their services and rules. These charges can vary by card brand, transaction type, region, volume, refunds, or other activity. Providers often pass them through on the statement or include them in a bundled rate.
Because providers format statements differently, ask which network charges they pass through and how those line items appear. For the separate roles of gateways and processors—and why gateway charges may appear—read the payment gateway vs. payment processor guide.
3. Processor markup and provider charges
The provider sets its markup and may also charge for services or equipment. Common items include:
- A percentage and a fixed amount per transaction
- Monthly, annual, statement, or batch fees
- Gateway and POS software charges
- Equipment purchase, rental, or lease costs
- PCI-related, chargeback, refund, or early-termination fees
This portion often offers the most room to compare providers. However, a low transaction rate can still cost more once you add account, gateway, software, or equipment charges. Ask for a complete fee schedule and sample statement.
Compare your effective rate
Use the same fee categories and sales period when comparing accounts:
Effective rate = total processing fees ÷ total card sales × 100
For example, $300 in processing fees on $20,000 in card sales equals a 1.5% effective rate. Include fees that belong to card acceptance; list separate software or equipment expenses as additional costs when they sit outside the processing account. For a step-by-step statement review, see the effective processing rate and payment-fees guide.

Pricing models at a glance
- Flat rate: One standard percentage and transaction charge; simple to estimate, but compare it against your actual volume.
- Interchange-plus: Separates network interchange from provider markup, which can make the markup easier to see.
- Tiered: Places transactions into categories; ask what determines each category before comparing quotes.
- Subscription: Combines a recurring plan fee with transaction charges; check whether the monthly cost fits your typical sales.
Questions to ask before choosing a provider
- Which fees come from the card networks, and which ones do you set?
- What is your percentage markup and per-transaction charge?
- Which account, gateway, software, equipment, PCI, and support fees will I pay?
- Can you show a sample statement and estimate my effective rate from recent sales?
- How can card mix, keyed sales, refunds, or settlement timing affect qualification?
Finally, compare written proposals using your own volume, average ticket, card mix, and channels—not a promotional rate alone. Local POS Broker can help Florida businesses review POS equipment, payment channels, provider options, and processing-cost questions based on how they accept payments.
For an example of a broader merchant-services range, The Direct Processors’ services section lists recurring billing, a QuickBooks plug-in, invoicing, electronic checking, gateway integration, and POS options. Confirm current availability and terms with each provider.
