Compare cash reserves and an unused business credit line
Updated: 9 hours ago
Accessible cash reserves and an unused credit line can both support liquidity, but they carry different access conditions, costs and repayment consequences.
A business with $50,000 in its account and another with a $50,000 undrawn limit do not necessarily have the same capacity to handle a difficult month. The difference becomes clearer when the money is needed urgently.
For Australian owners, the decision is how each source behaves under the business’s actual obligations and stress scenarios. Start with the broader working capital needs guide, then distinguish money owned from money that may be borrowed under an agreement.
The short answer
Identify what cash is genuinely available after existing commitments and restrictions.
Verify every condition required to draw an unused facility, including review and expiry provisions.
Include fees and the repayments created when a limit is used.
Test whether the business can still meet obligations if access is delayed or unavailable.
What counts as usable cash reserves?
Begin with account balances the business can access when needed. Deduct or separately identify money already committed to payroll, suppliers, tax and other obligations. Also investigate customer advances or restricted funds that cannot simply be redirected.
A deposit with a notice period or a balance supporting another obligation may not be immediately usable. Confirm the practical access arrangements instead of assuming every asset described as cash can fund tomorrow’s payments.
The government’s cash flow statement guidance provides a reference for forecasting movements. The 13-week forecast guide helps turn an apparently healthy balance into a calendar of receipts, obligations and remaining headroom.
Choose the reserve with reference to the business’s risks. A company collecting daily card receipts has a different pattern from one waiting for a handful of large project payments. There is no single months-of-expenses rule that resolves every operating situation.
An unused limit is an agreement to investigate
Read the facility documents to establish when money can be drawn and for what purposes. Check whether approval conditions, security requirements or information updates must be satisfied before access. A preliminary indication is different from a settled, accessible facility.
Confirm the review date, final maturity and any required reductions. Ask what circumstances can affect access or require repayment. Do not assume a facility will renew automatically or remain available through a material deterioration in trading.
The business loan and revolving facility comparison explains why product labels do not settle these questions. Two arrangements described as a line of credit can have different drawdown and repayment mechanics.
Keep operational details current too. Know who is authorised to request a draw, where proceeds arrive and what processing steps are required. A limit is less useful in a short-notice disruption if the person able to access it is unavailable.
Compare the costs of holding and using capacity
Cash held in reserve may have an opportunity cost. It could otherwise reduce debt or support a commercially useful investment. That does not mean it should be spent, because retaining access also has value when receipts become uncertain.
An undrawn facility may have establishment, ongoing or availability charges, depending on its agreement. Drawing funds can introduce interest and scheduled repayments. Confirm which charges apply to the approved limit, the drawn balance or individual transactions.
Use the working capital loan costs guide to frame the comparison. Compare total incremental costs over the same scenario and period, rather than placing an annual rate beside a reserve balance and treating that as a complete answer.
Your accountant can assess the financial and tax implications. Your finance broker can help explain available structures, while a lawyer should review material contractual obligations. The reserve decision should reflect those findings and the business’s operating priorities.
A worked example: The limit creates a later payment
Consider a hypothetical business with a possible $40,000 gap if its largest customer pays three weeks late. It has $25,000 of genuinely unallocated cash and an existing $30,000 undrawn facility, subject to its terms.
Under the assumed scenario, using all $25,000 and drawing $15,000 would cover the initial gap. That calculation does not yet establish affordability. The business must also forecast the funding charges and any repayments beginning before or shortly after the customer pays.
Now suppose access to the facility requires an unresolved condition. The business cannot count the $15,000 as available until that condition and drawdown timing are confirmed. A spreadsheet line labelled “available credit” does not complete the requirement.
These are original illustrative assumptions, not a quote or a recommendation to use every dollar of reserves. The example shows why access certainty and the cash position after drawing matter alongside the headline sum of cash and limits.
Test a disruption that affects both receipts and credit
Liquidity planning is strongest when it considers connected risks. A trading downturn can reduce customer receipts at the same time the business needs to provide updated information for a facility review. Do not assume every funding source remains unchanged in the difficult scenario.
Ask what the business can do if access is delayed, reduced or unavailable under the agreement. Potential actions might include rescheduling discretionary spending, agreeing supplier arrangements or staging a new project. Include only actions management can credibly implement within the required time.
The cash flow improvements guide considers operating responses. Delaying earned wages or ignoring agreed payment obligations should not be treated as spare contingency capacity.
If the forecast depends on new borrowing simply to meet existing repayments, review the underlying position. ASIC’s financial difficulty guidance supports seeking qualified help early when a company is struggling. Access to additional money does not settle questions about sustainable trading.
Avoid double counting the same headroom
An account balance may already include drawn overdraft funds. Adding the full facility limit to that balance can overstate liquidity. Work from the actual drawn balance, undrawn availability and the agreement’s access conditions.
Likewise, do not allocate the same reserve to payroll, a tax provision and an expansion deposit without showing the sequence. Separate purposes can compete for one pool of money even if each looks affordable in isolation.
Receivables-based availability requires particular care. A nominal limit may exceed current eligible funding, and a collection can reduce the outstanding advance rather than create wholly new free cash. Reconcile the structure with your accountant and finance broker.
The government’s business loan application guide is useful preparation for a facility discussion. Present a clear debt schedule and current cash position so available capacity is not confused with gross account movements or a previous approval amount.
Decide how the reserve will be used and rebuilt
Agree the events that justify using reserves and who authorises the decision. Distinguish a temporary receipt delay from a planned purchase or a recurring operating deficit. Those situations may need different responses.
After use, identify the cash expected to rebuild the reserve or repay the draw. A customer receipt can close a timing gap, but only the amount left after other commitments is available for replenishment. Review that sequence in the forecast.
Use a short review checklist:
How much cash is unrestricted and unallocated today?
What conditions, deadlines and costs apply to each unused facility?
Which repayments begin if the facility is drawn?
What happens if the largest receipt is late and credit access changes?
What specific receipts or retained cash restore the buffer afterwards?
Frequently asked questions
Is an approved limit the same as cash?
No. It is borrowing capacity governed by an agreement. Confirm that all access conditions are met and that the money can arrive when required.
Should every business keep the same reserve?
No. Consider receipt volatility, customer dependency, fixed commitments, operating flexibility and funding access. Review the amount with your accountant using realistic scenarios.
Does unused credit always cost money?
Costs depend on the facility. Read the fee schedule and distinguish charges on the limit from charges arising only when funds are used.
Can the reserve repay itself after the busy period?
Only if sufficient cash remains after the busy period’s costs and other obligations. Forecast the actual collection and replenishment sequence rather than assuming it happens automatically.
Know which money can meet which payment
Record usable cash and conditional borrowing capacity separately, then test them together against the operating calendar. The decision should leave a credible response to difficult weeks and a clear plan for the commitments created by drawing finance.
