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. Unlike generic overseas tools, this Cash Flow Forecast Calculator is built around current Australian rates and rules.

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.
How Our Cash Flow Forecast Calculator Works
A cash-flow forecast projects your **closing cash position** month by month by tracking money in against money out — regardless of accounting profit. Each month the calculator does: **Closing cash = opening cash + cash inflows − cash outflows**, and that closing balance becomes the next month's opening balance. - **Inflows** are actual receipts: sales collected, loans drawn, capital injected. - **Outflows** are actual payments: wages, rent, stock, tax, loan repayments, drawings. Rolling this forward across 12 months reveals your **lowest cash point** — the moment you're most at risk of running short — and whether the trend is building a buffer or draining one. The critical insight is that **profit and cash aren't the same**: a profitable business can still run out of cash if customers pay late or stock is bought ahead of sales. Because it's based on *timing* of receipts and payments, the forecast exposes gaps that a profit-and-loss statement hides. The projection is only as good as your assumptions, so revisit it as real figures come in.
When to Use This Calculator
Use a cash-flow forecast as a standard planning tool, not just in a crisis. **At the start of each year or quarter**, to map expected inflows and outflows and spot the months where cash gets tight. **Before big commitments** — a large stock order, a new hire, an equipment purchase — to check you can fund them without dipping below zero. **When seeking finance**, since lenders and investors expect a forecast and it shows exactly when and why funding is needed. **When customers pay slowly**, to model the impact of late payments and plan a buffer. It's vital for startups, seasonal businesses and any SME managing growth. Update it regularly with actuals so the forward view stays realistic.
