Any small business owner will know that keeping an eye on outgoings is a must. When trying to keep track of your cash flow, small costs can quickly add up. In particular, credit card merchant fees (transactional charges) can have a big effect on your bottom line.

As credit cards help you spread the cost of spending, customers will often use them to pay for purchases. The charges that come with these credit card purchases can be difficult for small businesses to deal with - especially alongside the monthly or yearly tariff necessary to keep a merchant account.

What are credit card merchant fees?

Merchant fees are transactional charges issued to businesses by banks whenever accepting credit card payments from customers. The fees will depend on the type of card the customer uses and the network through which the transaction is made. Some of these fees include:

Merchant service chargeThe MSC, or merchant service charge, makes up most of your merchant fees. MSCs are charged as a percentage of every sale made.

Terminal chargesBrick-and-mortar businesses may use a payment terminal for collecting sales. Terminal charges refer to the cost of keeping a chip and PIN machine and can vary depending on its quality.

Gateway feesPayment gateways are used for processing online transactions, providing a secure environment for transactions to take place. The fees for these gateways will depend on which provider you decide to go with - some charge per transaction, while others have a flat monthly rate.

Authorisation feesOn top of transaction fees, there are also costs for authorisation. Authorisation fees validate the card being used and make sure that there is sufficient credit available.

PCI compliance feeAny business that accepts credit card payments must follow PCI DSS. This is the industry data security standard for card payments and ensures all customer data is safely stored and sent.

Administrative feesDepending on what payment processor you go for, you may have to pay additional admin fees. For example, some processors charge new merchants a one-time set-up fee. Chargeback fees are also another example of these admin fees.


How much are credit card merchant fees?

There are a few different criteria that determine the amount you'll be expected to pay for these fees, which altogether can be quite tricky to understand. These include:

  • The nature of your business
  • The average transaction amount
  • The payment processor you use

There are, however, some guidelines for each fee - it’s important to note that some are monthly subscriptions, whilst others are based on individual transactions. Use the below as an estimate for your own business:

  • Merchant service charges - Debit cards: 0.25% to 0.6%/Credit cards: 0.3% to 0.9%/Commercial credit cards: 1.5% to 2.5%
  • Terminal charges - Fixed terminal: £14 to £20/Portable terminal: £16 to £25/Mobile terminal: £20 to £35
  • Gateway fees – 6p-10p per transaction/Fixed fees: £10-£20 monthly
  • Authorisation fees - 1p-6p per transaction
  • PCI compliance - £2-£20 per month
  • Administrative fees can vary greatly, depending on things such as chargebacks.
