Annual Percentage Rate, or APR, is one of the most quoted figures in lending. It sits at the top of comparison tables and is stamped across financial adverts to help borrowers understand the true cost of credit. For mortgages and personal loans, it works well. For short-term business finance, it can paint a deeply misleading picture — and understanding why is essential before you sign any agreement.
How APR Is Calculated and Where It Falls Short
APR converts all borrowing costs — interest, arrangement fees, and compulsory charges — into a single annual figure. The intention is standardisation: one number, one basis for comparison.
The problem is the word annual. When a business takes out a six-month loan, the lender calculates what those costs would amount to if the agreement ran for twelve months. The result is a rate that can easily reach triple figures even when the actual amount repaid is modest and perfectly reasonable for the product on offer.
Consider a £20,000 working capital facility repaid over four months. The total cost might be £2,400 — a flat 12 percent over the term. Annualised, that becomes roughly 36 percent APR. Neither figure is dishonest, but the APR figure, stripped of context, is the one that tends to cause alarm.
"APR is an excellent compass for long-term borrowing. For short-term products, it is a compass pointed at the wrong destination. What matters is the total cost relative to the value the finance creates for your business."
What to Look at Instead
For short-term business loans, the following metrics offer a clearer view:
Total repayable amount. This is the simplest and most honest figure. Add all repayments and fees together. Whatever that number is, that is what the loan costs you.
Factor rate. Common in merchant cash advances and revenue-based finance, a factor rate multiplies the principal by a fixed decimal. It ignores timing but is easy to audit alongside the repayment schedule.
Cost per day or per week. For very short facilities, breaking the cost into a daily figure gives you an intuitive sense of affordability against daily or weekly revenue.
Providers such as Credicorp publish cost breakdowns that go beyond the headline APR, allowing borrowers to see exactly what they will repay before they commit. When you are evaluating any lender, this kind of transparency is a strong signal of responsible lending practice.

Comparing Lenders Correctly
When you are placing two loan offers side by side, the comparison only holds if the terms are equivalent. A six-month loan and a twelve-month loan for the same amount will produce very different APRs even if the cost-per-pound is identical. Here is a reliable framework:
- Fix the loan amount and term across every quote you request.
- Note the total repayable figure for each, not just the rate.
- Identify any fees that fall outside the APR calculation, such as early repayment charges or administration costs.
- Assess repayment structure — daily, weekly, or monthly — against your actual cash flow cycle.
The ASA requires that financial advertising is clear and not misleading, and the FCA holds regulated lenders to strict disclosure standards. But regulatory floors are a starting point, not a ceiling. You can find guides on assessing advertised rates on the ASA financial advertising pages, and the GOV.UK business finance section provides impartial guidance on borrowing options for UK businesses.
If you are currently weighing up working capital options, exploring what Credicorp's business loan products actually cost in pounds rather than percentages is a good place to ground your comparison in real figures. For context on how cash flow finance fits alongside other funding types, see our overview of business funding options for UK SMEs.
APR will always be part of the lending conversation, and it should be. But treating it as the only number that matters — especially on short-term products — is one of the most common and costly mistakes business borrowers make. Understand what it measures, know its limits, and you will be far better placed to choose finance that genuinely suits your business.
Frequently asked questions
Why does the APR on a short-term business loan look so high?
APR expresses costs as if the loan runs for a full year. When a loan lasts only three or six months, the annualisation process multiplies the actual cost, producing a figure that looks alarming but does not reflect what you genuinely pay.
What is a factor rate and how does it differ from APR?
A factor rate is a simple decimal multiplier applied to the amount borrowed. For example, a factor rate of 1.25 on a £10,000 loan means you repay £12,500 in total. Unlike APR, it does not account for time, so it is only useful alongside the loan term.
Are UK business lenders required to show APR?
The FCA requires consumer credit APR disclosure, but business lending falls outside the Consumer Credit Act for most limited companies. Lenders may still show APR voluntarily, and responsible providers publish full cost breakdowns so borrowers can make informed decisions.
