Quick answer
The cost of slow finance is everything a business loses while it waits for money: missed supplier discounts, idle equipment and staff, lost contracts, late-payment penalties and ATO interest that compounds daily. Comparing the extra cost of fast finance with the cost of waiting — in dollars, over the actual delay — often shows that a slightly dearer loan arriving tomorrow is cheaper than a cheaper one arriving next month.
Key points
- The cheapest loan isn't the cheapest outcome if it arrives too late.
- Waiting has a cost: lost discounts, downtime, penalties, compounding interest.
- ATO GIC compounds daily and, from 1 July 2025, isn't tax deductible.
- Compare finance options on total cost over the time you'll actually hold them.
- Sometimes the honest answer is to wait — the maths tells you which.
Business owners are taught to shop for the cheapest finance — and in a calm month, with no deadline, that’s sound advice. But finance doesn’t exist in a vacuum. Money that arrives three weeks after you needed it isn’t cheap; it’s late. This guide is about putting a dollar figure on waiting, so you can compare options honestly rather than on headline cost alone.
What does waiting for money actually cost?
The costs of slow finance are real but scattered, which is why they’re easy to ignore. Common ones:
| Cost of waiting | How it shows up |
|---|---|
| Lost supplier discounts | Early-payment or bulk discounts expire |
| Lost allocations | Stock goes to a competitor who paid first |
| Idle equipment | A broken machine stops production |
| Idle staff | Wages paid while work can’t proceed |
| Lost contracts | A client picks someone who could start now |
| Late-payment penalties | Supplier late fees, contract penalties |
| ATO interest | GIC compounding daily on overdue tax |
| Personal liability risk | Director penalty deadlines passing |
| Stress and distraction | Hours spent juggling instead of running the business |
Not all of these apply every time. But usually one or two do, and they can be measured.
How do you put a number on it?
A simple three-step comparison:
- Estimate the daily (or weekly) cost of not having the money. Add up the items above that apply.
- Estimate the realistic delay of the slower option. Banks commonly take weeks; fast lenders can take a day or two.
- Compare: extra cost of the faster finance versus daily cost of waiting × days of extra delay.
If the cost of waiting is bigger, the faster option is cheaper in practice, even if its headline price is higher. If the cost of waiting is close to zero, take the time and the cheaper money.
What about ATO debt specifically?
Tax debt is the clearest case, because the ATO publishes how it charges. The general interest charge is calculated on a daily compounding basis on the overdue amount, and the ATO reviews the rate each quarter. Since 1 July 2025, GIC incurred can’t be claimed as a tax deduction — so the after-tax cost of carrying a tax debt is now higher than it used to be.
In a 2025 update to small businesses, the ATO encouraged owners carrying tax debt to make payments or arrange payment plans, and to talk to a registered tax professional about alternatives such as business loans. Waiting doesn’t just cost interest; large debts left overdue for more than 90 days can be reported to credit bureaus if a business isn’t engaging, and directors can face personal liability under the director penalty regime.
If an ATO debt is your situation, compare the cost of a loan against continuing GIC and those risks — see ATO tax debt funding. If the comparison favours acting now, you can start an application and have the ATO statement ready.
What does the comparison look like in practice?
Three illustrative examples, using round numbers to show the method:
1. The breakdown. A regional bakery’s main oven fails. Without it, it loses about $1,800 a day in wholesale orders. A bank loan for a replacement might take three weeks; a fast unsecured loan could fund tomorrow, at a higher total cost of, say, $2,500 more over its term. Waiting three weeks costs roughly 20 × $1,800 = $36,000. The faster loan is far cheaper in practice. (See equipment breakdown.)
2. The supplier discount. A wholesaler is offered 6% off a $200,000 stock order if it pays within 10 days — a $12,000 saving. Its bank needs four weeks. A short-term loan funds in two days and costs around $5,000 over the three months it’s needed. Net gain from moving fast: about $7,000. (See supplier deposit.)
3. The no-deadline upgrade. A design studio wants $60,000 for new computers and a fit-out, with no deadline and no lost revenue in the meantime. Waiting four weeks for a cheaper bank loan costs nothing extra. Here the slower option wins — and we’d tell you so.
Why do owners underestimate the cost of waiting?
A few reasons:
- The finance cost is on paper; the waiting cost isn’t. An offer shows a number. Lost sales don’t send an invoice.
- Optimism. “The bank will come through next week” — and then it’s the week after.
- Sunk effort. Having started with one lender, it’s hard to switch, even when the delay is costly.
- Not counting your own time. Hours spent chasing money are hours not spent on customers.
How do you get fast finance without overpaying?
Speed and value aren’t opposites. The fastest files are usually the best-prepared ones, and being well prepared also gives you more options:
- Have documents ready. A finance-ready folder cuts days off and lets you compare offers.
- Use security if you have it. Property-secured loans can be both fast and lower-cost than unsecured options.
- Set up standby funding. A line of credit arranged in advance gives you instant access at pre-agreed terms — the best of both worlds.
- Compare total cost over the time you’ll hold the loan, not just the headline. A short-term loan held for six weeks costs very differently from one held for a year.
- Plan the exit. Repay as soon as the need passes.
When is waiting the right answer?
When the daily cost of waiting is genuinely zero, or close to it. When there’s no deadline, no penalty, no opportunity that disappears and no interest compounding. In those cases, take your time, compare widely and choose the cheapest suitable finance — even if it’s slow. Our guide on when fast finance is the wrong answer goes further.
How do you run the comparison when you’re under pressure?
When a deadline is close, a full spreadsheet isn’t realistic. A quick version that takes five minutes:
- Write the deadline at the top of a page. The date the money must be paid, or the date the opportunity disappears.
- List what happens if you miss it. Be specific — “lose the $12,000 discount”, “pay two staff to sit idle”, “ATO debt keeps compounding”, “client gives the job to someone else”.
- Put a rough dollar figure on each item per week of delay. Round numbers are fine.
- Ask each lender two questions: how soon could funds realistically arrive, and what’s the total cost over the time I expect to hold the loan?
- Compare the difference in cost with the difference in delay. If the faster option costs $3,000 more but saves two weeks at $5,000 a week, the decision makes itself.
Write the result down. It’s surprisingly useful later, when you’re reviewing the decision or explaining it to a business partner or accountant.
And if, after doing this, the honest answer is that waiting costs very little, that’s a perfectly good outcome. You’ve avoided paying for speed you didn’t need, and you can use the extra time to compare cheaper options properly.
Does slow finance ever cost nothing at all?
Rarely, but it happens. If the money is for an upgrade with no deadline, a purchase with no time-limited price, or a buffer you’d simply like to have, the cost of waiting a few weeks may be close to zero. In those cases, patience and a careful comparison of offers will almost always save money.

Frequently asked questions
Isn't fast finance always more expensive?
The product often is — short-term and private lending are generally priced higher than long-term bank loans. But the outcome isn't always more expensive, because waiting for cheaper money can cost more than the difference.
How do I work out the cost of waiting?
List what you lose each day or week without the money — lost revenue, idle wages, penalties, interest charges, discounts forfeited — and multiply by the realistic delay of the slower option.
Does the ATO charge interest on late tax?
Yes. The general interest charge is calculated on a daily compounding basis on overdue amounts, and GIC incurred on or after 1 July 2025 can't be claimed as a tax deduction.
When is it better to wait for slower finance?
When nothing is lost by waiting — no deadline, no penalty, no opportunity that disappears — and the slower option is meaningfully cheaper. Then patience pays.
