Quick answer
Saving up avoids finance costs, but waiting has a cost too: the gross profit the growth move would have earned while you saved, plus the risk the opportunity disappears. Compare the total cost of finance with the profit you'd give up by waiting. If the forgone profit is larger — and the move is proven enough to borrow against — borrowing now usually leaves the business better off.
Key points
- Waiting to pay cash has a cost: the profit the move would have earned in the meantime.
- Compare that forgone profit with the total cost of finance, in dollars.
- Some opportunities have a deadline — a contract, a lease, a competitor's exit.
- Untested ideas are better self-funded or tested small; proven moves are better candidates for borrowing.
- Cost of borrowing
- Total cost of finance in dollars
- Cost of waiting
- Monthly boost × months spent saving
- Hidden cost of cash
- A thinner buffer for everything else
“We’ll do it when we can pay cash.” It’s a sensible instinct, and plenty of successful businesses were built that way. It’s also an instinct with a hidden price tag. Every month spent saving for a growth move is a month the move isn’t earning. Sometimes that price is small. Sometimes it’s bigger than the entire cost of borrowing.
What does waiting actually cost?
Three things:
- Forgone profit. If a move would add $5,000 a month of gross profit and it takes 18 months to save for it, waiting costs about $90,000 of profit you never earn.
- Lost opportunity. The shop next door gets leased. The contract goes to a competitor. The retiring owner sells to someone else. Some growth moves have a window.
- A thinner buffer. Spending your savings on growth leaves less for a slow quarter, an ATO bill or a broken machine.
Borrowing costs something too: the total cost of finance, in dollars. The decision comes down to which cost is larger — and which risks you’d rather carry.
How do you compare the two?
| Borrow now | Save, then pay cash |
|---|---|
| Move starts earning immediately | Move starts earning after the saving period |
| Pay the total cost of finance | No finance cost |
| Keep your cash buffer | Buffer spent on the move |
| Repayments from the move’s own profit | No repayments |
| Opportunity captured | Opportunity may be gone |
A simple comparison:
Cost of waiting = monthly boost × months spent saving
Cost of borrowing = total cost of finance
If the cost of waiting is clearly larger, and the move is proven enough that the boost is reliable, borrowing is likely the better choice. Our ROI on borrowed money guide covers how to estimate the boost.
A worked example (illustrative)
A mechanical workshop wants a second hoist and diagnostic equipment for $70,000. It’s turning away about 25 services a month, each worth around $260 of gross profit after parts and technician time. After extra running costs, the move adds a boost of about $5,500 a month.
The owner can save around $4,000 a month. Paying cash means waiting about 18 months.
- Cost of waiting: 18 months × $5,500 = about $99,000 of forgone gross profit, plus the risk that turned-away customers find another workshop and don’t come back.
- Cost of borrowing: a quote over three years shows a total cost of finance of about $14,000. The average repayment of about $2,300 is covered well over twice by the boost.
Borrowing now leaves the workshop roughly $85,000 better off over the period — and with its savings still in the bank as a buffer. Run your own version in the Growth ROI calculator, and if the comparison looks like this, see what your move could qualify for.
When is saving the smarter choice?
Borrowing isn’t always right. Saving (or testing small) wins when:
- The idea is unproven. A new product nobody has bought, a new market you haven’t tested. Borrowed money should scale winners, not search for them.
- The boost is uncertain. If you can’t estimate it within a sensible range, the cost of waiting is also uncertain.
- Cash flow is already tight. Adding repayments to a stretched business can make things worse, even for a good move.
- There’s no deadline. If the opportunity will still be there, time spent saving also gives you time to validate demand.
What questions help you decide?
Run through these before choosing:
- How sure am I of the boost? Could I defend the monthly figure with evidence — turned-away work, a waiting list, a signed customer?
- Is there a deadline? Will the opportunity still exist once I’ve saved?
- What would I do with the savings instead? Keeping them as a buffer has real value in a business with lumpy cash flow.
- Can the move carry its own repayments? If the boost covers the repayment comfortably, the rest of the business isn’t funding the growth.
- Would I regret waiting? Sometimes the honest answer to this one tips the balance.
What about a mix?
Many owners split the difference: contribute part of the cost from savings and borrow the rest. That lowers the amount borrowed, reduces the total cost of finance and keeps some buffer intact. It also shows a lender you have skin in the game. See business growth loans for how growth facilities are typically structured, and debt vs equity if you’re weighing an investor instead.
How does the current lending market affect the decision?
The Reserve Bank’s October 2025 Bulletin on small business conditions reported that access to finance had improved, noting that finance that is unsecured or secured by non-physical assets had reportedly become more readily available amid competition among lenders. That doesn’t make every growth move a good idea, but it does mean well-planned moves are more likely to find a structure that fits — so the “wait until we can pay cash” default deserves a fresh look.
Stop waiting on a move that’s ready
If your growth move is proven and the numbers show waiting costs more than borrowing, it may be time to act. Tell us what you’re planning and what it will earn.
Asking costs you a minute, not a mark on your credit report — we don’t run a credit check when you first get in touch. Your enquiry isn’t passed down a chain of lenders either. A real person looks at the move you’ve been saving for and calls to talk through whether acting now makes sense. Straight answers on the form get you to the right option sooner.
Frequently asked questions
Is it better to borrow or save for business growth?
It depends on how proven the move is and how much profit waiting would cost. If the move is well tested and would earn more while you save than the total cost of finance, borrowing now usually wins. If the idea is untested, saving or testing it small first is often wiser.
What is the cost of waiting in business?
It's the profit a growth move would have produced during the time you spend saving up for it, plus the risk that the opportunity disappears — a competitor moves first, the premises is leased, the contract goes elsewhere.
Should I use my cash reserves to fund growth instead of borrowing?
Using all your reserves can leave the business exposed to a slow month, a large tax bill or an unexpected repair. Many owners prefer to keep a cash buffer and fund growth with finance matched to the move, so the reserve stays available for surprises.
Can I combine savings and borrowing?
Yes, and it's common. Contributing some of your own cash reduces the amount and total cost of finance, while borrowing the rest lets you act now and keep a buffer.
