Quick answer
The cost of delaying a business investment is the sum of four things over the waiting period: profit you don't earn, price increases on what you'll eventually buy, the extra costs of making do in the meantime, and one-off losses such as a missed discount or contract. Add them up for your realistic waiting time and compare the total with the dollar cost of finance. The larger number is usually the more expensive choice.
Key points
- Waiting has a cost even when nothing leaves your bank account.
- Four parts: lost profit, price rises, making-do costs and one-off losses.
- Use your realistic waiting period, not an optimistic one.
- Compare the total with the dollar cost of finance — not a percentage.
Business owners are trained to watch costs that leave the account: rent, wages, fees, interest. The cost of waiting is different. Nothing leaves the account. The money simply never arrives. Because it’s invisible, it’s easy to ignore — and that’s why delay so often ends up being the expensive option.
What are the four parts of the cost of waiting?
Every delay can be broken into four parts. Estimate each one over your realistic waiting period.
| Part | Question to ask | Example |
|---|---|---|
| 1. Lost profit | What would this investment earn each month? | Extra jobs, extra covers, faster output |
| 2. Price movement | Will it cost more when I finally buy? | Supplier price review, freight, currency effects on imports |
| 3. Making do | What does working around the problem cost? | Repairs, hire, overtime, outsourcing |
| 4. One-off losses | What disappears if I wait? | A discount, a contract, a lease, a staff member |
Add parts 1 and 3 monthly, multiply by the months you’d wait, then add parts 2 and 4. That total is your cost of waiting.
How do I estimate lost profit honestly?
This is the part people either wildly overestimate or skip altogether. Be conservative:
- Use profit, not revenue. Extra sales bring extra costs.
- Allow for a ramp-up. New equipment, staff or sites rarely hit full output in week one.
- Use evidence: jobs you declined last quarter, a waitlist, customer requests, supplier data.
- If you genuinely can’t estimate it, that’s a signal to gather evidence first — see when waiting is smarter.
What about price increases?
Prices rarely stand still. The ABS reported the CPI rose 4.0% in the 12 months to August 2026, and many business inputs — trade services, materials, freight, equipment — move on their own cycles. If you have a written notice of an increase, use it. If you don’t, use a cautious estimate, or leave it at zero and see whether the decision changes. Our page on supplier price increase notices shows how to test a specific increase.
Illustrative example: the print shop
Illustrative only — invented figures.
A print shop is considering a wide-format printer for $48,000. It currently outsources large-format jobs. The owner’s plan is to save for it over 10 months.
- Lost profit: in-house printing would add about $2,600 a month in margin → $26,000 over 10 months.
- Price movement: the supplier has confirmed a 5% price increase in the new year → about $2,400.
- Making do: outsourcing couriers and rush fees cost about $400 a month → $4,000.
- One-off losses: a regular client has asked for a same-day banner service that the shop can’t offer; losing that account is a real risk, but the owner leaves it at zero to be cautious.
Cost of waiting 10 months: about $32,400. The total dollar cost of financing the printer over two years, as quoted, is far lower. The printer also generates the margin that meets the repayments.
This is exactly the calculation our cost-of-waiting calculator runs. If yours comes out the same way, see whether you qualify.
What’s the fair comparison on the finance side?
The total dollar cost of the facility over the time you’ll have it: establishment and ongoing fees plus interest, all in dollars. Don’t compare a monthly figure with a total, or a percentage with a dollar amount. business.gov.au suggests looking at fees, terms, security and repayment capacity when comparing lenders — all of which feed into that single dollar figure.
When does the cost of waiting mislead?
Three traps:
- Optimistic profit. If the lost-profit figure is a hope, the whole number is inflated.
- Ignoring risk. A bigger payoff with a higher chance of failure isn’t necessarily better.
- Forgetting repayments. Even a great investment can strain cash flow if repayments start before the profit does.
That’s why the cost of waiting is one input to the decision, not the whole decision. For the full framework, read should I borrow now or wait and our worked examples guide.
How do I stress-test my cost-of-waiting figure?
Before relying on the number, push on it:
- Halve the lost profit. Does waiting still cost more than borrowing? If yes, the case is robust.
- Double the waiting period. Saving up often takes longer than planned once wages, super and BAS take their share.
- Remove the price increase. If the answer only works with a price rise included, it’s fragile.
- Delay the benefit. Assume two or three months of ramp-up before the investment earns anything.
If your decision survives all four, you can be fairly confident. If it flips on one, that’s the assumption to firm up before committing — a trial, a signed order or a breakdown log. Our worked examples guide shows four businesses running exactly this kind of test.
Found out what waiting really costs?
If the number surprised you, it’s worth a second opinion from someone who does this every day. A 60-second enquiry is all it takes. Asking doesn’t involve a credit check; your details aren’t fed to a pack of lenders, and one specialist calls to go through the numbers with you. Please answer accurately — especially the amount and what it’s for — so the options you hear about actually fit.
Frequently asked questions
What is the cost of waiting in business?
It's the value you give up by delaying a decision: profit the investment would have earned, price increases while you wait, costs of working around the problem, and opportunities that disappear. It's a real cost even though it never appears on an invoice.
How is the cost of waiting different from opportunity cost?
They overlap. Opportunity cost is the value of the best alternative you give up. The cost of waiting is a specific kind: what you lose by acting later instead of now. Our guide on opportunity cost covers the wider idea.
How long a waiting period should I use?
The realistic one. If you'd save for the purchase, how many months would saving really take, given everything else competing for cash? Most owners underestimate this.
What if the cost of waiting is smaller than the cost of finance?
Then waiting is likely the cheaper choice, as long as nothing else changes. It's a perfectly good answer and worth knowing.
