How Much Should a Small Business Spend on Marketing? (Australian Guide)
A common benchmark for established Australian businesses is allocating 5% to 10% of total revenue to marketing, while early-stage or fast-growing businesses often invest 12% to 20%. However, the most sustainable strategy involves working backward from Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV) to build unit-economics-driven budgets.
Setting an effective marketing budget requires going beyond generic rules of thumb. While percentage-of-revenue benchmarks provide a helpful starting point, optimizing growth for an Australian small business depends on understanding unit economics, customer acquisition costs, and resource allocation.
Percentage-of-Revenue Benchmarks
Revenue percentages serve as a baseline to evaluate overall marketing investment relative to business maturity:
While revenue percentages offer a high-level sanity check, they do not guarantee campaign profitability. Moving to a customer unit economics model provides greater precision.
The Unit Economics Model: Working Backward from Customer Value
Instead of relying strictly on top-line percentages, base your budget on unit economics: Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV). If acquiring a customer costs $150 via paid search or local SEO and yields $750 in gross margin, marketing functions as a predictable revenue engine rather than an overhead expense.
Budget Allocation for New Australian Businesses
If you lack historical conversion metrics, treat early promotional capital as an investment in market data gathering. Focus initial expenditure on high-intent conversion channels like Google Search Ads, Google Business Profile optimization, or hyper-targeted social media campaigns. Limit early tests to 1–2 primary acquisition channels, establish baseline CAC data over 60–90 days, and reallocate capital toward top-performing tactics.
Factoring In Internal Labor and Tooling Costs
Effective budget management accounts for operational labor alongside direct media buy spend. Time allocated by internal staff to content production, website maintenance, or ad optimization represents real financial overhead. When calculating true acquisition costs, incorporate software subscriptions, creative assets, and specialized agency or freelancer support alongside direct ad spend.
