How much does a business loan actually cost?

Found Funding · Guides

Ask a lender "what will this loan cost me?" and the honest answer is: it depends. That is frustrating when you are trying to plan, but it is also fair, because the cost of a business loan is built from several moving parts, not one headline number. The good news is that once you understand what those parts are, you can compare offers properly, spot the expensive ones, and stop being sold on a low monthly payment that quietly costs you far more over the full term.

The building blocks of the cost

Every business loan is priced from a handful of ingredients. Understanding each one is what lets you read an offer rather than just react to it.

• Interest rate and APR. The interest rate is the cost of the money itself. The APR (Annual Percentage Rate) is more useful because it folds in compulsory fees to give a truer annual cost, which makes it the fairest way to compare like for like.
• Arrangement or facility fees. Many lenders charge a one-off fee to set the loan up, often a percentage of the amount borrowed. It might be deducted from what lands in your account or added to the balance.
• Other fees. Watch for early-repayment charges, late-payment fees, drawdown fees, and on some facilities a broker fee. None of these are automatically bad, but they belong in your comparison.
• Secured vs unsecured pricing. A secured loan is backed by an asset such as property or equipment, which lowers the lender's risk and usually the rate. An unsecured loan has no such backing, so it typically prices higher.

Fees that don't show up in the headline rate

The interest rate is the number lenders lead with, but it is rarely the only figure that moves the cost. A handful of charges sit alongside it, and because they are not always folded into the advertised rate, it is easy to miss them until the offer letter lands. Before you sign anything, ask explicitly about each of these:

• Arrangement or facility fee. Commonly a percentage of the amount borrowed, taken either as a deduction from what you receive or added to the balance you repay.
• Non-utilisation fee. On a revolving facility or overdraft, some lenders charge for the undrawn portion of an agreed limit — the headroom you have not used. It rewards keeping the agreed limit close to what you actually need rather than asking for more than you intend to draw.
• Early-repayment or exit charge. A penalty — sometimes fixed, sometimes a percentage of the remaining balance — for clearing the loan ahead of term. If there is any chance you will refinance or pay down early, this matters as much as the headline rate.
• Renewal fee. Facilities reviewed annually, such as overdrafts and some revolving credit, can carry a fee simply to renew the agreement, whether or not your usage has changed over the year.
• Default and late-payment fees. Charged on top of any default interest if a payment is missed, and worth knowing about even if you do not plan to miss one.

None of this makes a lender untrustworthy — it is how most facilities are priced. The discipline is to ask for the full fee schedule alongside the rate before you accept an offer, not after.

Why two businesses get two different rates

Business lending is risk-based. The lender is pricing the chance of not being repaid, so the stronger and more predictable your business looks, the cheaper the money tends to be. Trading history, turnover, profitability, credit profile, the sector you operate in, and how much you want relative to your revenue all feed into the rate you are offered.

As a very rough, illustrative guide only, unsecured business loans in the market commonly sit somewhere around high-single-digit to 20%+ APR depending on risk, while secured facilities can price lower because there is an asset behind them. Those are not our figures, they are broad market ranges, and everything is subject to status and to the lender's own assessment. Do not anchor to a number you read online; anchor to the actual offers in front of you.

Term length: the quiet cost multiplier

Here is where a lot of borrowers get caught. A longer term lowers the monthly payment, which feels cheaper, but it usually means you pay interest for longer and hand over more in total. A shorter term costs more each month but less overall. Neither is right or wrong; it is a trade-off between monthly affordability and total cost, and the answer depends on your cash flow.

A worked illustration

Imagine borrowing £50,000. These figures are illustrative only, to show the shape of the trade-off, not a quote.

• At around 12% over 3 years, the monthly payment is roughly £1,660, and the total repaid is about £59,800, so roughly £9,800 in interest.
• The same £50,000 at the same rate over 5 years drops the monthly payment to roughly £1,110, but the total repaid climbs to about £66,700, roughly £16,700 in interest.

Same loan, same rate. Stretching the term cut the monthly figure by around a third but added several thousand pounds to the total. If a broker leads with "only £1,110 a month", that is the number that flatters the longer, more expensive deal. This is exactly why you compare the total cost of borrowing, not the monthly payment in isolation. You can run your own version of this with our business loan calculator.

Secured vs unsecured: the same amount, two different costs

Illustrative example only — not a quote from Found Funding or any lender, and not what anyone has been offered. Take a business borrowing £40,000 for a refit, over the same three-year term either way.

Offered unsecured, say at 14% APR with a 2% arrangement fee, the monthly repayment comes to roughly £1,370, and the total repayable over three years is about £49,300, fee included.

Offered secured against a company asset at 8% APR with a 1.5% arrangement fee, the monthly repayment drops to roughly £1,255, and the total repayable comes to about £45,800.

The gap — around £3,500 over three years on the same £40,000 — is broadly the price of the lender having nothing to fall back on in the unsecured version. It is not a fixed rule that secured always wins by that much: a strong trading history and a clean credit file can narrow the gap, and some lenders price unsecured lending competitively for well-established companies. But where you do have an asset to offer and are comfortable with the lender holding a charge over it, it is worth asking for both a secured and an unsecured quote on the same amount before deciding — the difference is often bigger than it looks from the rate alone. See asset finance for how security against a specific item works, and business loans for how secured and unsecured borrowing compare more broadly.

Personal guarantees and what they really do

Many unsecured business loans, especially for smaller or younger companies, come with a personal guarantee. This does not change the interest you pay, but it changes the risk you carry: you are personally promising to cover the debt if the business cannot. Because it reduces the lender's exposure, it can help you access finance or improve the terms, but it is a serious commitment. Read exactly what is guaranteed, by whom, and for how much before you sign.

How to compare offers like a professional

• Total repayable, first. Add up every payment plus fees over the full term. That single number cuts through a lot of noise.
• Use APR to compare. It is designed to make different structures comparable.
• Read the fee schedule. Arrangement, early-repayment and default fees change the real cost.
• Match the term to the purpose. Short-term needs rarely justify long-term interest.
• Check flexibility. Can you overpay or settle early without penalty if cash flow improves?

The cost of a business loan is never just the rate on the front page. It is the rate plus the fees plus the term plus the security plus your own risk profile, all pulling in different directions. A whole-of-market search lets you see how those variables land across multiple lenders at once, so you are choosing on the full picture rather than a single tempting figure. Whatever you are weighing up, remember that finance is subject to status, an approval is never guaranteed, and the cheapest monthly payment is very rarely the cheapest loan.

Common questions

Is APR always the fairest way to compare two business loans?

It is the best single number for comparing straightforward term loans against each other, because it folds compulsory fees into one annual figure rather than leaving you to add them up yourself. It gets less reliable once you are comparing different structures — a term loan against a revolving facility, or a fixed-term loan against invoice finance priced on a discount rate — because APR assumes a steady, scheduled repayment that those products do not always follow. In those cases, go back to the total amount repayable over a realistic timeframe rather than relying on APR alone to settle the comparison.

Do I need a personal guarantee for every business loan?

No, but it is common on unsecured lending to smaller or younger companies, where the lender has no asset to fall back on and limited trading history to judge. Secured lending, and facilities to larger or longer-established businesses, are more likely to go ahead without one, though it still depends on the individual lender's policy. A guarantee does not change the interest rate you are charged; it changes who is on the hook if the business cannot repay. Always check exactly what is covered, whether it is capped at a fixed amount, and whether it is shared across directors before signing.

Can I repay a business loan early to cut the interest?

Often, yes, but check the early-repayment terms before assuming it saves you money. Some facilities charge a fixed exit fee or a percentage of the outstanding balance if you clear the loan ahead of schedule, which can offset some or all of the interest you would have saved. Others let you overpay or settle early with no penalty at all. This is exactly the kind of detail that does not show up in a headline rate comparison, which is why it belongs on the same checklist as the APR and the arrangement fee, rather than being checked only once you are ready to pay the loan off.

Does my credit score decide whether I am offered a secured or unsecured rate?

It is one input, not the only one. Lenders also weigh trading history, turnover, profitability, sector, and how much you are asking for relative to your revenue, so a short-trading but highly profitable business can be priced quite differently from a longer-established one with thinner margins, even with similar credit files. Offering security changes the picture separately from credit, because it gives the lender somewhere to turn if things go wrong, which is why two businesses with identical credit scores can still be offered different rates depending on what, if anything, is backing the loan. The loan comparison calculator is a quick way to see how a real offer stacks up once you have one in front of you.
