New Zealand revolving credit

A limit that is still there after you repay it.

An independent guide to business lines of credit and overdrafts in New Zealand, and a calculator that shows what a drawn balance actually costs. Nothing here is a quote, and no details are collected.

Indicative only. Not a quote or offer of credit. Actual rates, fees, and repayments depend on the business profile and the lender's decision.

What this is

One instrument, several names.

Almost every business facility is a single event. Money is advanced, a schedule repays it, and the arrangement ends. A revolving facility is different: a limit is approved once, drawn when needed, repaid when cash allows, and the capacity comes back without a new application.

That one difference changes everything else. Interest applies to the balance rather than the amount approved, the price includes a fee on the limit whether or not it is used, there is no schedule forcing the balance down, and the limit can be reduced at a review. Understanding those four things is most of what a business needs before taking one.

This site covers each kind of revolving facility on its own page, in the same shape, so they can be compared rather than described. The calculator sits on every page and shows what a drawn balance costs. Nothing here is a quote, nothing is submitted, and no credit file is touched.

How the four most common New Zealand revolving arrangements differ. Indicative only, and not an offer of credit.

The decision underneath

Two questions settle most of it.

Question one

Will the money be wanted again.

A need with a size and an end is an event, and a term loan funds an event well: a lower rate, a schedule that clears it, and no temptation to leave a balance sitting.

A need that reopens every quarter is a condition, and a facility that repays to zero funds the last occurrence rather than the next. A business in that position ends up servicing two loans for one problem.

That question decides the instrument better than any comparison of rates, and it takes a minute to answer honestly.

Question two

What stands behind the limit.

Security moves both the rate and the limit, and on a revolving facility it moves them further than on a term loan, because the lender is committing to an open-ended exposure.

It also exposes assets to the limit rather than to a declining balance, for as long as the facility exists. That is a different proposition from securing a loan of the same size.

The middle position, a general security agreement over the business rather than a mortgage over a home, captures much of the pricing benefit while keeping the consequences inside the business.

The number to watch

The lowest balance matters more than the highest.

A revolving facility is working when it comes back down. Recording the least drawn the facility gets in each cycle, and comparing it against the previous two, is the earliest available signal that a limit has stopped revolving and started funding a permanent position. A rising floor is telling a business something a profit and loss statement will not show for another year, and it takes two minutes a cycle to keep.

The honest limit

What this site cannot tell you.

Every rate band here is indicative. Nobody publishing a website in New Zealand can say what a specific business will be charged, because the price is a function of trading history, security, the amount and a credit assessment, and only the lender sees all of them. The bands describe a market rather than an offer.

The same applies to limits. What a lender will write depends on the cash cycle, the security and the conduct it can see, and a page that named a number would be describing a policy nobody published.

This site is an education site and a calculator. It is not a lender, a broker or a registered financial adviser, and nothing on it is personalised financial advice.

FAQ

Revolving credit in New Zealand, questions answered

What is a business line of credit?

An approved limit a business can draw against and repay at will, with interest charged only on the balance outstanding. Repaying restores the capacity, so the facility is available again without a new application.

Is a line of credit the same as an overdraft?

Mechanically almost identical. Both are revolving limits charging daily interest on the drawn balance. What differs is that an overdraft sits on the trading account, so it is drawn and repaid automatically through ordinary trading.

What does a facility cost when nothing is drawn?

The line fee, charged on the approved limit whether or not it is used, plus any review charge. On a facility held largely undrawn as a buffer, the fee is most of the annual cost.

How is the annual cost worked out?

From the average drawn balance across the period rather than from the limit, plus the standing charges. That is why the calculator on this site asks for a drawn balance rather than an amount borrowed.

When is a term loan the better choice?

When the need has a size and an end. A term loan is cheaper on money that is genuinely needed continuously, and it comes with a schedule that clears it, which a revolving facility does not.

Can a lender reduce the limit?

On the terms in the agreement, yes, and most small business facilities are uncommitted. Asking whether a facility is committed or uncommitted is the most useful question about how much weight to put on it.

What does security do to a limit?

It raises the limit and lowers the rate, both materially. It also exposes the secured assets to the full limit for as long as the facility exists, because a revolving balance does not amortise.

Is a revolving credit home loan the same thing?

No. That is a consumer mortgage feature with different mechanics and different regulation, and it is the meaning most New Zealanders meet first. Using one to fund a business is common and it is a much larger decision than it appears.

What does a lender look at when setting a limit?

Bank statements first, particularly the low points and how often they are reached, alongside the cash cycle, existing commitments and any security offered. A limit justified by a described cycle is easier to grant than a round number.

Does this site arrange finance?

No. It is an education site with a calculator. There is one disclosed referral to Prospa on the calculator, no contact form, and no personal details are collected anywhere on the site.

Disclaimer

Indicative content only. Not personalised financial advice.

A revolving facility is a standing commitment serviced out of the same operating cash flow as everything else, and the interest and fees recur for as long as it is held. Modelling the weekly cost against the trading position before committing is what this site is built for. Borrowing at a level that stays comfortable through a quiet quarter, rather than only through a strong one, is widely regarded as the safer frame.

What this site is

A calculator and information tool. Not a lender, not a broker, not a registered financial adviser. Nothing here is personalised financial advice.

What the figures show

Modelled estimates based on the inputs shown. Not a quote. Not an offer of credit. Not a guarantee of approval, rate or fees.

What the lender decides

Final rates, fees, and approval are set by the lender after a CCCFA-appropriate assessment of the applicant's circumstances and credit decision.

Commercial disclosure

Lineofcredit.org.nz earns a commission from Prospa when a visitor applies through this site and their application is approved. The commission is paid by Prospa, not by the borrower, and it does not influence the rate Prospa offers. Full disclosure on the partner page.

Tax, GST, and accountant framing

Tax-treatment statements (GST claim timing, interest deductibility, depreciation rates) are general in nature and subject to the accountant's confirmation on the specific business position. For material amounts, professional advice from a registered financial adviser or chartered accountant is widely regarded as the safer frame.

About this site, the figures, and your protections.

Last reviewed 8 September 2026.

1. What this site is

Lineofcredit.org.nz is a New Zealand education site and a free repayment calculator. It is not a lender, not a broker, and not a registered financial adviser. We do not arrange credit, hold client money, or provide regulated financial advice as defined under the Financial Markets Conduct Act 2013 Part 6 or the Financial Services Legislation Amendment Act 2019. Nothing on this site is personalised financial advice.

2. The calculator and figures

All numbers shown by the calculator, in worked examples, and across the site are indicative only and modelled from the inputs entered. The figures are not a quote, not an offer of credit, and not a guarantee of the rate, fees, term, or approval available to any specific business. Final pricing, fees, and approval are set by the lender after the lender's own credit assessment.

3. General information, not advice

Content on this site is general information (class information). It does not take into account the financial situation, objectives, or needs of any particular business or person. Before making a borrowing decision, professional advice from a licensed Financial Advice Provider, a chartered accountant, or a solicitor is widely regarded as the safer frame, particularly where amounts are material or the borrowing involves a personal guarantee.

4. Commercial relationship with Prospa

When a calculator user clicks "see if you qualify", the application hands off to Prospa, our New Zealand SME finance partner. Lineofcredit.org.nz earns a referral commission from Prospa when a referred application converts to a funded loan. The commission is paid by Prospa, not by the borrower, and does not change the rate, fees, or terms Prospa offers the business. We do not claim Prospa is the cheapest or best lender for every applicant. Full disclosure is on our partner page.

5. Tax, GST, and accountant framing

Tax-treatment statements (GST claim timing, interest deductibility, depreciation rates) on this site are general in nature and subject to confirmation by the accountant on the specific business position. For material amounts, professional tax advice from a chartered accountant is widely regarded as the safer frame. Inland Revenue is the primary source for any specific NZ tax-treatment question.

6. Privacy and personal information

Consistent with the Privacy Act 2020, we do not run lead-capture forms on this site. Calculator inputs stay in the browser and are not transmitted to a server we control. We use Google Analytics 4 for aggregate, non-personal traffic data only. When a visitor clicks through to Prospa they leave our site, and Prospa's privacy policy applies. The Credit Contracts and Consumer Finance Act 2003 (CCCFA) framework applies at the lender level where a sole trader's borrowing is wholly or predominantly for personal use, or where a personal guarantor is involved.

7. Fair dealing posture

This site operates under the fair-dealing requirements of the Financial Markets Conduct Act 2013 Part 2 and the Fair Trading Act 1986. We avoid misleading or deceptive conduct, false representations, and unsubstantiated claims. Numeric or regulatory claims are hedged or sourced to a primary New Zealand authority such as Inland Revenue, MBIE, the Companies Office, WorkSafe, the Reserve Bank of New Zealand, Stats NZ, the Commerce Commission or the Financial Markets Authority.

8. Limitation of liability and governing law

To the maximum extent permitted by New Zealand law, Lineofcredit.org.nz, its operators and its contributors are not liable for any loss or damage (direct, indirect, consequential, or otherwise) arising from use of the site or reliance on its content, indicative figures, or third-party information.
