About the Cash Flow Forecast Calculator
The Cash Flow Forecast Calculator Australia helps you predict future cash inflows and outflows so you can make informed business decisions. Cash flow is the lifeblood of any Australian business, and the ATO expects you to meet your PAYG withholding, GST, and super guarantee obligations on time. A reliable cash flow forecast prevents surprises and keeps your business solvent. The RBA frequently highlights that poor cash flow management is a leading cause of small business failure in Australia. This tool gives you a forward-looking view, helping you identify potential shortfalls before they occur. Whether you are planning for seasonal fluctuations, expansion, or simply want better financial control, this calculator provides the clarity you need.
What is the Cash Flow Forecast Calculator?
This calculator projects your future cash position by combining your expected income and expenses over a selected period. It uses your opening cash balance, adds projected receipts from sales and other income, subtracts forecast payments for expenses, and shows your closing cash balance for each period. For Australian businesses, cash flow forecasting is essential for BAS preparation, GST payments, and managing supplier relationships. The calculator accounts for the timing differences between when you issue invoices and when payments actually arrive. It also factors in regular commitments like wages, rent, loan repayments, and superannuation guarantee contributions. A rolling 13-week forecast is considered best practice among Australian finance professionals.

Worked Australian Example
Practical Example
Consider Cairns Adventure Tours, a tourism operator in Queensland. The business starts July with $35,000 in the bank. Over the next 13 weeks, it expects: Inflows: $120,000 from tour bookings (with 60% arriving during the school holiday weeks in September), $8,000 from merchandise sales, and a $12,000 GST refund from the ATO. Outflows: $45,000 in wages including superannuation, $18,000 in fuel and vehicle maintenance, $9,000 in insurance premiums, $7,500 in loan repayments, $14,000 in marketing spend, and $22,000 in ATO payments (PAYG and BAS). The forecast shows that in late August, before the school holiday revenue arrives, the cash balance dips to $8,200. The business arranges a $20,000 overdraft facility to cover this gap. By late September, the balance recovers to $68,000, allowing the business to prepay some insurance and reduce the overdraft. The 13-week forecast gives the owner confidence to plan marketing spend without risking insolvency.
