The cash position after settlement can be as important as the purchase price.

Business Cash Buffer Calculator
Estimate how many months of operating runway remain before and after a major cash purchase.
A cash buffer gives the business time to absorb delayed payments, seasonal weakness, repairs, tax obligations and unexpected opportunities. There is no universal number for every business; the appropriate buffer depends on volatility, debtor timing, fixed costs and access to reliable funding.

Comparison
Potential advantages and trade-offs.
Why a business may consider finance
- Turns a vague comfort level into a measurable runway
- Shows how a cash purchase changes operating resilience
- Supports better discussion with directors and advisers
- Helps identify when financing could preserve necessary headroom
What the business gives up
- A calculator cannot predict every cash event
- Average monthly costs may hide seasonal peaks
- Future tax and capital commitments must be added separately
- Excessive idle cash may also have an opportunity cost
Interactive tool
Model the decision.
Adjust the assumptions to see how the structure changes liquidity, repayment pressure or estimated cost. The output is educational and intentionally conservative.
Use conservative cost assumptions and separately allow for BAS, tax, owner drawings, capex and seasonal peaks.
Practical example
Put the structure into context.
Illustrative scenario
A business holding $300,000 with monthly operating costs of $90,000 has about 3.3 months of runway before considering upcoming tax or capex. A $150,000 cash purchase would reduce that to about 1.7 months.
Balanced decision
When cash or finance may fit.
A blended structure can also be considered—for example, contributing a deposit from surplus cash while financing the long-lived asset and retaining an operating buffer.
FAQs
Frequently asked questions.
How many months should a business hold?
There is no single correct number. Volatile or seasonal businesses may prefer more runway than stable recurring-revenue businesses.
Should undrawn credit count as cash?
It can support liquidity but is not the same as cash because lender availability can change.
What costs should be included?
Payroll, rent, suppliers, tax obligations, insurance, existing repayments and other essential overheads.
