How the budget is calculated
Multiply annual revenue by the percentage you select, then divide by 12 for an average monthly figure. With $500,000 of annual revenue and a self-chosen 10% allocation, the scenario is $50,000 per year or about $4,166.67 per month. The tool does not select the percentage for you or assess whether the business can afford it.
Build the real plan from activities
Map the intended audience, channel, goal, timing, and costs. Include production, staff or agency time, software, research, media, events, and a contingency where appropriate. A company with uneven cash collections may need a month-by-month spending plan rather than one-twelfth of an annual figure each month. Check profitability and cash flow before committing spend.
Review and adjust
Business.gov.au recommends setting goals, channels, costs, timing, and evaluation in a marketing plan. Compare actual spend and useful outcomes against those choices. A higher budget cannot repair an unclear offer, weak audience fit, or missing conversion tracking. The appropriate share varies by sector, growth stage, margin, and capacity, so document why you chose it.
