Why do credit card processing fees change over time?

As a business owner, you might notice fluctuations in the credit card processing fees you pay. These changes can impact your operational costs, so it’s important to understand why they might occur. Let’s explore the main reasons behind these variations.

Market and Economic Changes

Credit card processing fees are influenced by broader economic factors. For instance:

  • Inflation: General increases in prices and wages can lead to higher operational costs for payment processors, which may be passed on to merchants in the form of increased fees.
  • Economic Stability: During times of economic uncertainty or downturn, processors might adjust fees to offset increased risks, such as higher rates of chargebacks or fraud.

Changes in Interchange Rates

Interchange rates are fees set by credit card networks (like Visa and MasterCard) that make up a significant portion of credit card processing fees. These rates can change due to:

  • Updated Pricing Models: Credit card networks periodically adjust their pricing structures based on market research, profit goals, and competitive pressures.
  • Regulatory Changes: Government regulations can affect how much banks and credit card companies are allowed to charge for transactions, directly impacting interchange rates.

Technological Advances

As technology evolves, the cost of processing payments can fluctuate:

  • New Payment Technologies: The adoption of newer technologies (e.g., contactless payments, mobile wallets) often requires initial investments, which can temporarily increase processing costs.
  • Improved Security Measures: Enhanced security protocols like EMV compliance and advanced fraud detection systems may increase costs for processors, who then adjust their fees accordingly.

Competitive Landscape

The payment processing industry is highly competitive, and shifts in the market can lead to changes in processing fees:

  • New Entrants: The entry of new companies into the payment processing market can lead to price adjustments as existing companies alter their fees to stay competitive.
  • Mergers and Acquisitions: Consolidation in the industry can affect fee structures as larger entities may leverage economies of scale to offer different pricing.

Merchant-Specific Factors

Changes in a merchant’s own business can also lead to adjustments in processing fees:

  • Sales Volume and Transaction Size: Generally, higher volumes and larger transactions can lead to lower per-transaction fees due to economies of scale.
  • Industry and Transaction Type: Certain industries or types of transactions (e.g., online vs. in-store) carry different levels of risk and costs, which can influence fee adjustments.
  • Credit Risk: Changes in a merchant’s creditworthiness might prompt processors to adjust fees to mitigate risk.


Credit card processing fees are not static and can change for a variety of reasons, including economic factors, technological advancements, market dynamics, and changes within your own business. Understanding these factors can help you anticipate changes and manage your payment processing needs more effectively. As always, staying informed and reviewing your merchant statements regularly can help you keep on top of these changes and ensure that you are getting the best possible rates for your business.
