You signed your merchant agreement at 2.4% plus 10 cents. A year later, you're looking at a statement and the effective rate is 2.8%. Nothing in your business changed. Your card mix is the same. Your volume is the same. But your costs went up.

Welcome to the passive rate increase — one of the quietest and most common ways processors raise prices on merchants who aren't watching.

Almost every merchant agreement includes language allowing the processor to modify rates and fees with notice. The key word is "notice" — which sounds protective until you read what qualifies as notice.

In most agreements, notice means:

  • A line on your statement. A tiny footnote on page 4 of a document most merchants never read.
  • An email to the address on file. Even if that email bounces or goes to spam.
  • 30 days to object. If you don't respond within the window, you're considered to have accepted the change.

Some agreements go further and allow increases without any notice at all for "pass-through fees" — a category that processors define broadly enough to include almost anything.

What gets raised

Processors have several levers they can pull:

  • Per-transaction markup. The fixed fee above interchange. Moves from $0.08 to $0.10, or 0.20% to 0.30%.
  • Statement fees. $5 becomes $10. $10 becomes $15.
  • PCI compliance fees. $8/month becomes $14/month.
  • Batch fees. Per-batch settlement charges creep up from $0.15 to $0.25.
  • "Regulatory compliance" fees. New line items appear with vague names to justify the extra cost.
  • Network pass-through increases. When Visa or Mastercard raise assessment fees, some processors pass through more than the actual increase and pocket the difference.

The individual changes are small. Two or three of them compounding over a year is how your effective rate drifts from 2.4% to 2.8% without anyone calling it a rate hike.

How to catch it

The easiest way to spot rate creep is to track your effective rate month over month. Total fees divided by total volume. If it's trending up and nothing about your business has changed, something on the processor side has.

Specific things to check on each new statement:

  • Compare line-item fees to last month. Statement fee, PCI fee, batch fee, gateway fee. Any of them different?
  • Look for new line items. A "Regulatory Compliance Assessment" or "Network Security Fee" that wasn't there before is a rate increase in disguise.
  • Check the per-transaction markup. On interchange-plus pricing, this is easy to see. On flat or tiered pricing, watch the blended rate for upward drift.
  • Read the small footnotes. Notification of fee changes often appears as a one-line note at the bottom of the statement. Look for it specifically.

If your statement is 8 pages of jargon and you can't quickly tell whether rates changed, that's not an accident. That's the design.

What to do when you find it

Once you've confirmed a rate increase, you have more leverage than you think:

  • Call retention and ask for the increase to be reversed. Frame it as "I noticed my rates went up — I need them restored to the original agreement." Many processors will roll them back on request for good customers.
  • Cite the cancellation clause. Most agreements include a provision that lets you cancel without penalty if the processor raises rates. If they won't reverse, you can leave — and tell them so.
  • Escalate past your rep. Front-line reps often can't reverse changes. The retention team can.
  • Document everything in writing. Email your request and save the response. If they refuse in writing, you have grounds to cancel without ETF.

How to prevent it going forward

The best defense is in the next contract you sign:

  • Demand a rate-lock clause. Your rates and fees cannot increase for the duration of the contract without your written consent.
  • Require 60 days written notice (not a statement footnote) for any fee change, with an unconditional right to cancel.
  • Refuse automatic renewal. Month-to-month terms make passive rate increases much harder to get away with.
  • Set a calendar reminder. Pull your statement and recalculate your effective rate every quarter. Ten minutes, four times a year, and you'll catch every drift.

The bigger picture

Processors raise rates because they can. Most merchants don't read their statements carefully, don't calculate their effective rates, and don't know they have the right to object. The ones who do notice and push back almost always win — because the processor knows that forcing the issue means losing the account. Your job is to be one of the merchants who notices.
