Processing fundamentals

Read your processing statement like an auditor

Most merchants look at one number on their statement — the total fee — and move on. That's exactly what processors are counting on.

The statement is designed to confuse you

This is not a conspiracy theory. It's a business model. A processing statement for a $45,000/month merchant can have 20 or more line items. Many of them have names that obscure their purpose. A few of them are pure profit for the processor — fees charged for things that don't cost the processor anything, dressed up with official-sounding names.

An experienced auditor can review a statement in ten minutes and identify whether a merchant is on a good deal or a bad one. Here's how to do it yourself.

Start with the effective rate

Before you look at a single line item, calculate your effective rate.

Total fees ÷ Total card volume = Effective rate

If your statement shows $1,350 in total fees on $48,000 in card volume, your effective rate is 2.81%. That's the number that matters most. Context:

  • 2.3%–2.6%: Well-structured interchange plus. You're likely on a competitive deal.
  • 2.6%–2.8%: Borderline. Could be interchange plus with average card mix, or tiered pricing with favorable volume.
  • 2.8%–3.2%: Common on tiered pricing. Worth auditing.
  • Above 3.2%: You are almost certainly on a punishing rate structure. This is fixable.

High-ticket businesses (average ticket over $100) typically run lower effective rates because fixed per-transaction fees are a smaller percentage of each sale. High-frequency, low-ticket businesses (coffee shops, QSRs) see the per-transaction fees amplified. For more on how the underlying interchange rates affect this math, see interchange fees explained.

The three legitimate cost layers

Your processing costs have three real components. Everything else is add-on.

Layer 1: Interchange Interchange is the fee paid to the card-issuing bank — the bank that issued the customer's Visa or Mastercard. It's set by the card networks, published quarterly, and non-negotiable. Rates range from 0.05% + $0.21 for regulated debit (Durbin Amendment) to 2.95% + $0.10 for premium rewards cards. On a good interchange plus statement, you'll see interchange broken out by card type — Visa CPS Retail, Mastercard World Elite, etc. — with the exact rate and a dollar amount for each bucket.

If interchange is buried in a single number or not broken out at all, you're likely on tiered pricing, which means the processor is deciding which bucket each transaction falls into — and not in your favor.

Layer 2: Assessments Assessment fees go to the card networks directly. Visa charges approximately 0.14% of volume. Mastercard charges approximately 0.1375%. Discover charges approximately 0.105%. American Express OptBlue charges approximately 0.165%. These appear on statements variously as "Visa assessment," "MC assessment," "network fees," or similar. They're legitimate passthrough costs. The total should be roughly 0.13%–0.15% of your volume.

Layer 3: Processor markup This is what your processor keeps. On a transparent interchange plus account, it appears as a clear percentage plus a per-transaction fee — e.g., "0.25% + $0.10 per transaction." On a tiered account, it's embedded in the bucket rates and impossible to isolate.

The junk fee lineup

Here is every fee that appears on statements that either shouldn't exist or should be far smaller:

PCI non-compliance fee ($19.95–$49.95/month): You haven't completed your annual Self-Assessment Questionnaire. Fix it — see PCI compliance in plain English for the 30-minute path to eliminating this fee.

PCI annual fee or compliance program fee ($79–$129/year or $9–$15/month): Charged by the processor's compliance portal vendor (Trustwave, SecurityMetrics, etc.). Some of this has legitimate cost — the portal gives you the SAQ tool and monitors your compliance status. But $129/year for a SAQ B-IP merchant is excessive. $4.99/month is more appropriate. Negotiate it.

Statement fee ($7–$15/month): A charge for generating your statement. Paper statements cost money; electronic statements don't. Make sure you're on e-delivery, and if the fee persists, ask to have it removed.

Monthly minimum ($25–$50): A floor guarantee for the processor. If you're processing $30,000+ per month, there's no reason to have a monthly minimum — your fees will always exceed the floor. Remove it.

Batch fee / settlement fee ($0.05–$0.25 per batch): Small, but meaningful at high batch frequency. $0.05–$0.10 is standard. Above that is markup.

IRS 1099-K reporting fee ($1.95–$5.95/year): The processor has to file a 1099-K with the IRS if you exceed reporting thresholds. This is required by law — it's not a service you elected. The actual cost to the processor is essentially zero. This fee is pure margin and should be removed.

Early termination fee accrual: Not a monthly fee, but look for contract language that establishes a "liquidated damages" clause tied to your remaining monthly minimums. A three-year contract at $25/month minimum, signed with 18 months remaining, implies a $450 termination fee. Know your exit cost before you sign anything.

Build your own mock audit

Here's the format. Pull your last three statements and fill this in:

| Category | Amount | % of volume | Notes | |---|---|---|---| | Interchange | $ | % | Should be largest line | | Assessments | $ | % | Should be ~0.13–0.15% | | Processor markup | $ | % | On IC+ = clear markup line | | Junk fees (total) | $ | — | Everything else | | Total | $ | % | = your effective rate |

If "junk fees" exceed $50/month and your volume is above $20,000, you have room to negotiate. If interchange is not broken out separately, you're on tiered pricing.

Bottom line

A clean statement on a well-priced account has four line items: interchange, assessments, processor markup, and maybe one small monthly fee. If you're counting more than eight line items, something is costing you money it shouldn't.

Frequently asked

What is my effective rate and how do I calculate it?

Your effective rate is the total you paid in processing fees divided by your total card volume for the period. Formula — total fees ÷ total volume = effective rate. Example — $1,200 in fees on $45,000 in volume = 2.67% effective rate. A typical well-structured interchange plus account runs 2.3%–2.6%. Above 2.8% is worth auditing.

What are assessment fees and who gets them?

Assessment fees are paid directly to the card networks — Visa, Mastercard, Discover, and Amex. They're non-negotiable and the same across all processors. Visa charges approximately 0.14% per transaction; Mastercard charges approximately 0.1375%–0.14%. These are legitimate and unavoidable — any processor trying to mark them up is adding margin to a passthrough cost.

What is the monthly minimum fee?

A monthly minimum guarantees the processor a floor revenue from your account. If your total processing fees for the month fall below, say, $25, the processor charges you the difference to hit $25. High monthly minimums on low-volume accounts are a hidden cost. Look for $25 or less, and none at all on high-volume accounts.

What is a batch fee?

A batch fee (also called a settlement fee) is charged each time you close your daily batch — typically $0.05–$0.10. On 20 business days, that's $1–$2/month. It's small but should be on your radar as a markup indicator. Processors that charge $0.25+ per batch are padding margin.

Can I negotiate statement fees away?

Some fees are non-negotiable (interchange, assessments). Others are entirely negotiable or removable — monthly minimum, statement fee, PCI annual fee, batch fee, IRS 1099-K reporting fee. When switching processors, use these as negotiating chips. A good reseller will push to eliminate most of them at onboarding.

Interchange plus vs. tiered pricing, decoded

Interchange plus passes the card networks’ published rate through at cost with one transparent markup. Tiered pricing buries it in three buckets — and the processor decides the bucket. Here is the math that ends the conversation.
