Business Loan Pricing: Interest, Fees and What Moves Them
The rate is one line of the price. Compare offers on everything you will pay, at the way you will use the money.
BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED
// THE SHORT ANSWER
A business loan's price is a base rate set by the wholesale market, a margin set by the risk the bank sees in your business, and fees: an establishment fee, often a line fee on the whole limit whether drawn or not, and break costs on fixed-rate money repaid early. Compare offers on everything you will pay at the balance you expect to draw, because a lower margin can cost more once the fees are in. The margin and fees are negotiable within the risk the bank sees; the base rate is not, and the size of the limit is yours to set.
BASIS Practitioner judgment from sixteen years in commercial banking, set out in How Bankers Think (Highbank Press, 2026). Every borrower on this site is a composite constructed for teaching, not a client. The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

// WHAT YOU ACTUALLY PAY
A business loan's interest rate is two numbers added together: a base rate, which is what money costs in the wholesale market and moves with it, and a margin, which is the bank's price for the risk it sees in your business and for its own costs. Around those sit the fees. Together they are the price, and an offer that quotes one of them is not an offer you can compare.
| Dimension | WHAT IT IS | HOW MUCH ROOM THERE IS |
|---|---|---|
| BASE RATE | WHAT IT ISWhat money costs the bank in the wholesale market; it moves with that market. | HOW MUCH ROOM THERE ISNone on the rate itself. The choice is whether to fix it, and for how long. |
| MARGIN | WHAT IT ISThe bank's price for the risk it sees in you, and for its own costs. | HOW MUCH ROOM THERE ISSome, within the risk the bank sees. The way to move it a long way is to change that risk. |
| LINE FEE | WHAT IT ISA charge on the whole limit, drawn or not — the price of the money being there. | HOW MUCH ROOM THERE ISNegotiable, and a smaller limit is a smaller fee. |
| ESTABLISHMENT FEE | WHAT IT ISA one-off charge when a facility is set up, and often again at renewal. | HOW MUCH ROOM THERE ISOften more flexible than the margin, especially on a renewal. |
| BREAK COSTS | WHAT IT ISWhat it costs to repay fixed-rate money before its fixed term ends. | HOW MUCH ROOM THERE ISSet by the contract. Read it before you fix, not when you want to leave. |
| OTHER FEES | WHAT IT ISMonitoring, excess or overlimit charges, security handling, guarantees issued for you. | HOW MUCH ROOM THERE ISWorth asking about one by one; together they can outweigh a margin difference. |
// 01 — TWO OFFERS, ONE FACILITY
An illustration, in round numbers and not a case. A business wants a US$4.0m revolving facility and has two offers on the same base rate of 4.50%. Offer A has a margin of 2.20%, a line fee of 0.50% a year and an establishment fee of 0.25%. Offer B has the lower margin, 1.70%, with a line fee of 0.80% and an establishment fee of 0.40%. The fees are charged on the limit, the interest only on what is drawn — so which offer is cheaper depends on how the business uses the facility.
Offer A: 6.70% × US$2.5m + 0.75% × US$4.0m = US$198k — 7.90% of what is drawn
Offer B: 6.20% × US$2.5m + 1.20% × US$4.0m = US$203k — 8.12% of what is drawn
Drawn to the full US$4.0m:
Offer A: 6.70% × US$4.0m + 0.75% × US$4.0m = US$298k — 7.45% of what is drawn
Offer B: 6.20% × US$4.0m + 1.20% × US$4.0m = US$296k — 7.40% of what is drawn
Offer B wins the headline and loses the year, unless the business is drawn above about US$3.6m on average — nearly the whole limit. The comparison that matters is the all-in cost at the balance you actually expect, and the same arithmetic says something about the limit itself. If the business never needs more than US$3.0m, Offer A on a US$3.0m limit costs:
Headroom is not free. A limit sized to the real peak, with the arithmetic to show the bank why, is often worth more than the margin argument.
// 02 — WHAT MOVES THE MARGIN
The margin is the part of the price that is about you, and it moves with four things. First, the risk the bank sees: how steady the cash flow is, how much debt the business already carries, what security stands behind the loan, the industry, the people running it, and how good the information is. Second, what the loan costs the bank to hold: the capital it must keep against it, and the cost of funding it for the term. Third, the rest of the relationship — deposits, transaction banking, other lending — which can carry part of the return a bank wants from a customer. Fourth, competition: a bank growing its lending in your industry prices to win, and one whose limits are full does not.
The spread is wide. New Zealand's Reserve Bank has said there is no single representative rate for small-business lending, because banks price by product, by sector and by the borrower's own risk, and its own figures show it: new small-business overdrafts averaged 10.06% in August 2026, while banks' whole business book yielded 5.11% in July 2026.
Only the first of the four is really in your hands, and it is the one that moves a margin furthest. The guide to how banks price a business loan builds the same price up from the bank's side, piece by piece.
// 03 — WHAT TO ASK FOR, AND HOW
Ask for everything in writing first: margin, every fee, the covenants, the security, the review date and the break-cost terms. Then negotiate the parts that have room. Fees often have more than the margin, especially at renewal. The limit is yours to set. The margin moves most when you change what it is priced on — accounts that arrive on time and reconcile, better security, less debt, a shorter term — and a useful question to ask your banker is simply what would move your grade.
Weigh the conditions as money too. A covenant set where your business will struggle to meet it can cost more in one bad quarter than a lower margin saves in five years, and a personal guarantee added to win a rate is a price paid in a different currency — the guarantees guide explains what it buys the bank. Bring a competing offer whole, not as a headline rate: a bank cannot match a number honestly without knowing what it is matching.
// 04 — WHEN THE CHEAPER OFFER IS NOT CHEAPER
When its fees outweigh its margin at the way you use the money, as in the illustration. When the lower rate comes with tighter covenants, more security or a guarantee. When a bank prices to win this year and reprices at the first review, once moving again would be expensive. And when the lender offering less knows your business less: in a bad year, a bank that has watched you through good ones is worth something that no rate sheet shows. The guide to refinancing counts what moving costs, before the saving.

// QUESTIONS PEOPLE ASK
- What fees do banks charge on business loans?
- Most business facilities carry an establishment fee when they are set up, and often at renewal; revolving and overdraft facilities often carry a line fee on the whole limit whether it is drawn or not; fixed-rate loans carry break costs if repaid early; and there can be monitoring fees, charges for going over a limit, and fees for bank guarantees issued on your behalf. Ask for all of them in writing before comparing offers.
- What is a line fee on a business loan?
- A fee charged on the full limit of a facility, usually revolving credit or an overdraft, whether or not the money is drawn. It pays for the bank keeping the money available and holding capital against it. Because it is charged on the limit, a facility much larger than the business uses costs money every year for headroom it never touches.
- Can I negotiate the interest rate on a business loan?
- The margin and the fees, yes, within the risk the bank sees in your business; the base rate, no. The most effective way to lower a margin is to change what it is priced on — accounts that arrive on time and reconcile, more or better security, lower debt, a shorter term — rather than to ask for a discount on the same risk. A complete competing offer helps; a headline rate without its conditions does not.
- Why is a business loan more expensive than a home loan?
- Because the bank sees more risk in it and must hold more of its own capital against it. A home loan is secured on a house the borrower lives in, is small relative to the value of that house, and belongs to a large, well-understood pool; a business loan depends on one business's cash flow, its security is often worth far less in a forced sale, and the bank spends more time assessing and watching it. Each of those costs appears in the margin.
- Should I fix the interest rate on a business loan?
- Fix the part of the debt you are confident will still be there for the whole fixed term, and leave floating the part you may repay, refinance or reduce. Fixing buys certainty about the rate; the price of that certainty is a break cost if you repay early while wholesale rates are lower than when you fixed. Revolving and seasonal borrowing, which goes up and down by design, is usually left floating.
