Business bank fees and charges: calculate what the account costs your company

The cheapest business account is not necessarily the one with the lowest monthly fee. The real cost depends on how the company actually banks: how many payments it sends, how much cash it deposits, whether it uses CHAPS or international transfers, and whether it borrows through the account.

Build a real transaction profile before comparing tariffs

Business.gov.uk recommends comparing providers on the features and eligibility that fit the business. The useful starting point is the last three to six months of actual account activity. Count outgoing electronic payments, incoming credits, cash deposits, cheque use, international transfers, card withdrawals and any high-value payments that need special processing.

A digital consultancy making 40 electronic payments a month has a different cost profile from a café depositing £8,000 of cash every month. The account with no monthly fee can still be expensive for the café if cash handling is charged heavily. Build the profile first, then apply each provider's tariff to the same usage.

Separate the monthly account fee from per-transaction charges

Some business accounts charge a fixed monthly fee, some charge by transaction, and others combine the two. Do not stop at the headline monthly price. Check charges for automated payments, cash paid in, cash withdrawn, cheques, branch transactions, additional cards and special services.

Suppose Account A costs £0 per month but charges 35p for each outgoing payment, while Account B costs £15 per month and includes those payments. At 100 outgoing payments, Account A costs £35 before any other charges, so Account B is £20 cheaper in that simplified comparison. At 20 payments, Account A may still be cheaper. Usage determines the result.

Model cash deposits by value and frequency, not just the percentage charge

Cash-heavy businesses should calculate exactly what their deposit pattern costs. Providers can price cash by percentage, per £100, per deposit or through minimum charges. Also include the cost of staff travel and time if the cash must be taken to a branch or Post Office location.

A retailer depositing £2,000 every week can face very different annual costs from an online business that never handles notes or coins. If a provider is attractive on digital payments but expensive on cash, the business should not average the two away. Cash is a distinct operating requirement and should be costed separately.

Include CHAPS, foreign exchange and international-payment charges

International payments can include a visible transfer fee, an exchange-rate margin and, in some cases, intermediary or recipient-bank charges. High-value domestic transfers can also incur CHAPS fees. These costs may be infrequent but material.

If a company converts £100,000 into euros each month, a 0.40 percentage-point difference in the effective FX cost is about £400 per month, or £4,800 a year, before transfer fees. That can matter far more than a £10 difference in the monthly account fee. Compare the full payment route using the company's normal transaction size.

Add overdraft, card and emergency-use costs to the account comparison

An account can be inexpensive while in credit and costly when the business borrows. Include overdraft interest, arrangement or renewal fees, unarranged charges where relevant, business-card annual fees and foreign-card charges. If the company relies on an overdraft regularly, borrowing cost belongs in the account comparison from the start.

For example, saving £120 a year in current-account fees is not meaningful if the new provider's overdraft costs £1,500 more at the company's typical utilisation. Use one annual banking-cost model that combines routine transactions with realistic borrowing.

Look beyond introductory free-banking periods

Startup and switcher accounts can offer free or discounted banking for an introductory period. That can be valuable, but calculate the ongoing annual cost after the offer ends. A company should not choose an account that becomes a poor fit in year two simply because year one is free.

Record the date the offer expires and review the account two or three months before then. Business.gov.uk also notes that traditional banks and fintech providers can differ in cash handling, lending, branches and specialist services. Price matters, but the lowest tariff is not good value if the business later needs a service the account cannot provide.

Keep the comparison model after opening the account. Once a quarter, replace the assumptions with actual transaction counts and actual fees from the statement. If the business has shifted from ten cash deposits a month to none, or international payments have grown sharply, the cheapest provider can change without any tariff changing at all. Banking cost is partly a pricing question and partly a usage question.
