30 day business loan: can you borrow for one month, and what do the fees do to it?

Plenty of business owners only need money for a few weeks: a deposit that’s paid back when a sale settles, a supplier bill that clears when a big customer pays. Borrowing for a month sounds cheap because it’s short. In practice, it’s the term where fees do the most damage, so it pays to do the sums before you ask.

This guide covers who writes a 30 day business loan, what the fees do to a one-month term, and the proof a lender will want that you can repay on time.

Can you get a 30 day business loan?

Yes, but it’s a narrower field than ordinary business lending. Banks and many online lenders set minimum terms of several months. The lenders who will write a 30-day, 14-day or 45-day loan are mostly in short-term property-backed lending: a caveat loan, a second mortgage or a bridging-style loan over residential or commercial property, with a defined repayment event.

Here’s how that lines up with the amount and speed bands we work to:

Need	Typical route for a one-month term	Speed
Smaller amount, trading business	Unsecured or cash flow option, though terms are often longer	Same-day funding possible
$20k to $250k	Property-backed	Possible same day
$250k to $5m	Property-backed	Possible within 24–48 hours once the file is complete

Nothing there is promised. Timing depends on the property, the paperwork and how quickly everyone signs. The speed claims describe what’s possible, not what’s guaranteed.

What do fees do to a very short loan?

Short-term loans typically carry two kinds of cost:

• Time-based cost: interest or a monthly charge for each month the money is out.
• One-off costs: establishment or application fees, valuation, legal and settlement costs, and sometimes an exit or discharge fee.

The one-off costs don’t care how long you borrow. Commonwealth Bank’s own fee guide, for example, notes that an establishment fee on a term loan can be a dollar amount or a percentage of the facility, and isn’t refunded if the loan ends early. Lenders vary, so read yours, but the principle is the same everywhere: paying a fixed fee once and then repaying in 30 days doesn’t give you a discount on the fee.

That’s why a one-month loan can cost more per day than a three-month loan, even though you’re borrowing for less time. The repayment calculator guide shows how to total these costs; here we’ll apply it to the 30-day case.

A worked example: $100k for 30 days versus 90 days

Here’s an illustration with round, made-up numbers. Suppose a lender quotes $100k against property:

• One-off costs (establishment, valuation, legal): $3,000.
• Time-based cost: $1,200 per month.

	30 days	60 days	90 days
One-off costs	$3,000	$3,000	$3,000
Time-based cost	$1,200	$2,400	$3,600
Total	$4,200	$5,400	$6,600
Cost per month held	$4,200	$2,700	$2,200

Two things stand out. The 90-day loan costs $2,400 more in total, but the 30-day loan costs almost twice as much for each month you hold the money. And if you pick 30 days and the settlement slips by a week, you’re into extension territory with new fees on top of the original $4,200.

The better question isn’t “what’s the cheapest term?” It’s “what’s the shortest term I can hit with a few weeks of safety?” If your payment is due on day 26 and could slip to day 40, the 60-day term in this example is worth the extra $1,200. That’s the same idea we cover in the cost of waiting for business funding: put a dollar figure on being late, then compare.

Ask any lender for the total dollar cost at each term in writing. The funding speed finder is a quick way to see which route suits your amount and deadline before you do that.

When is a 30-day loan the right tool?

It works when three things are true at once:

1. The repayment event has a date. A property settlement, a refinance approval or a customer contract with payment terms.
2. The event is documented. The paperwork exists today, not “we expect it”.
3. The gap is smaller than the cost of missing out. Losing a deposit, a discount or a contract costs more than the fees.

Typical cases include paying a deposit before a sale settles, covering a supplier until a confirmed invoice is paid, or clearing a payment so a refinance can complete. It’s a poor fit for ongoing cash flow shortfalls, because those don’t end on a date, and a loan that rolls over every month is the most expensive way to borrow.

What proof of repayment do lenders ask for on a one-month term?

With so little time, the lender is underwriting your exit more than your history. Expect to be asked for:

• a contract of sale with the settlement date, or a refinance approval or letter of offer;
• for a customer payment, the signed contract and invoice, ideally with remittance advice or payment terms in writing;
• property details if it’s security: address, rates notice, existing mortgage statement and payout figure;
• business bank statements and a list of what the business already owes;
• ID for every borrower, director and guarantor, and a way for each of them to sign quickly.

Our exit strategy guide explains how lenders weigh this, and what to do when the planned exit has a backup.

What should you check in the contract before signing?

On a one-month loan, a clause that would be a nuisance on a long loan can decide the outcome. Check:

• The extension terms: the fee, the extra cost per month and whether the lender is obliged to agree.
• Default and late fees: how much and from which day.
• Early repayment: whether paying off in week three saves you anything. Often the one-off fees mean it doesn’t.
• Exit or discharge fees: the lender’s cost to release the security.
• What “repayment date” means: the day cleared funds must arrive, not the day you send the transfer.

Small businesses have some protection here. ASIC explains that business loan contracts are examples of standard form small business contracts, and the unfair contract terms laws apply where the business has fewer than 100 employees or turnover under $10m and the upfront price (principal plus disclosed establishment fees, excluding interest) is $5m or less. Penalties for unfair terms have applied since the reforms commenced in November 2023. Default and late fees can be tested for unfairness, per ASIC’s guidance. That’s a safety net, not a reason to skip the reading, and only a court can decide a term is unfair.

What are the common mistakes on a 30-day loan?

• Choosing the term by the deadline, not the risk. A settlement date on the 30th is not a repayment date on the 30th. Money often arrives a few days later.
• Comparing monthly figures. A one-month quote that looks small ignores the one-off costs.
• No Plan B for the exit. If the sale falls through, what repays the loan? Have a backup refinance in mind.
• Starting late. A loan that must be funded in 24–48 hours needs documents sorted in advance. The same-day readiness checklist is the fastest way to get that done.
• Rolling it over. Two 30-day loans in a row usually cost more than one 60-day loan would have.

Where do you stand on a one-month loan?

If you’ve got a date, an amount and proof of how it gets repaid, a short loan can be a tidy answer. If any of those are shaky, a slightly longer term or a different structure usually serves you better, and it’s worth hearing that before you sign anything.

That’s what the enquiry is for. Tell us the amount and the date: it takes about 60 seconds, and there is no credit check when you enquire, so your credit file is untouched just for asking. We don’t pass your details around a pile of lenders, so your phone stays quiet. One real person reads your situation, works out which term and route fit, and calls you to talk it through.

Please fill the form in accurately, especially the amount, the date the money has to be there, what you’ll repay it from and what’s already owing on any property. The more honest the picture, the more likely the first option we put to you is one that works.
