How Much Should a Small Business Spend on Advertising in Australia?
A practical guide to budgets, Google Ads, Facebook and Instagram ads, and making every dollar work harder.
If you're running a small business in Australia, you've probably asked: how much should I actually spend on advertising?
Spend too little and you may struggle to reach new customers. Spend too much without a clear strategy and you could burn through your budget without enough sales to justify it.
There is no single budget that works for every business. A local tradie, an online retailer and a professional services firm all have different customer acquisition costs, margins and growth goals. But there are practical ways to decide how much to spend, where to put it and how to measure whether it's working.
Many small businesses start with around $500–$2,000 per month, depending on industry, location and growth goals. This is an illustrative planning range, not a universal benchmark or guarantee of results.
Your ideal budget depends on your profit margins, customer acquisition costs and ability to convert enquiries into paying customers.
1. How much should a small business spend on advertising?
Start with your revenue, business objectives and available cash flow. Some businesses set a percentage of revenue for marketing overall; others work backwards from how many new customers they need.
| Monthly revenue | Illustrative marketing budget at 5% |
|---|---|
| $10,000 | $500 |
| $20,000 | $1,000 |
| $30,000 | $1,500 |
| $50,000 | $2,500 |
| $100,000 | $5,000 |
These figures illustrate a budgeting method, not a recommended percentage for every business. The percentage covers the overall marketing budget, not advertising spend alone.
Your marketing budget may also need to cover website maintenance, creative, SEO, email marketing and software. Make sure you don't accidentally allocate the entire amount to paid ads. Advertising spend and total marketing expenditure are not the same thing.
2. What percentage of revenue should go to advertising?
These are planning examples, not industry standards. A business with a 10% profit margin has very different constraints from one with 50%. Avoid setting your budget on revenue alone: gross profit, operating expenses and capacity to handle new customers matter just as much.
3. How much should you spend on Google Ads and Facebook Ads?
Google Ads reaches people actively searching for your product or service. Facebook and Instagram Ads reach people based on interests, demographics and other targeting signals. Here's an illustrative split of a $1,000 budget:
| Channel | Monthly budget |
|---|---|
| Google Search Ads | $600 |
| Facebook and Instagram Ads | $300 |
| Testing new campaigns | $100 |
| Total | $1,000 |
This is an example, not a recommended split. An emergency plumber may prioritise Google Search, while a business selling visual products may do better on Instagram and Facebook. The best allocation depends on where your customers are and which channel generates profitable sales.
4. How much does it cost to advertise a small business in Australia?
Your advertising budget is not the same as the cost of managing your campaigns. A $1,000 Google Ads budget is generally your media spend. It may not include campaign management, landing pages, copywriting, creative or tracking setup.
| Expense | Monthly cost |
|---|---|
| Google Ads media spend | $1,000 |
| Campaign management | $400 |
| Landing page and creative allocation | $150 |
| Total monthly investment | $1,550 |
Hypothetical figures, not current Australian agency price averages. Fees vary by campaign complexity, scope and provider.
When comparing agencies, ask what fees include, whether platform charges are separate and who owns the advertising account.
5. Calculate how much you can afford to spend to acquire a customer
Instead of asking "how much should I spend on ads?", ask "how much can I afford to spend to acquire one paying customer?" Try it with your own numbers:
Based on spending 30% of gross profit per sale on acquisition. A planning illustration, not a guaranteed profitable budget.
The business here allocates only part of its gross profit to acquisition, leaving room for other expenses. The right figure also depends on repeat purchases, customer lifetime value, overheads and how long it takes to recover your investment. For subscriptions or repeat-customer services, looking only at the first sale can underestimate a customer's long-term value.
6. How to choose the right budget for your industry
| Business type | Advertising considerations |
|---|---|
| Tradies | Local search demand, service areas and the value of each job |
| Driving schools | Local competition, lesson packages and student enquiries |
| NDIS providers | Service areas, appropriate advertising and enquiry handling |
| Real estate agencies | Local brand awareness, listings and lead nurturing |
| E-commerce | Product margins, average order value and repeat purchases |
| Professional services | Client lifetime value and the cost of qualified enquiries |
A tradie earning substantial gross profit from one job can justify a higher acquisition cost than a business selling inexpensive products. A driving school may aim for students who buy multiple lessons rather than judging success by single bookings. Copying another business's budget leads to poor decisions, because your budget needs to reflect your own business model.

8. How to make a small budget go further
- Focus on one or two channels first until you know where customers convert.
- Target clear buying intent with relevant search terms, locations and defined audiences.
- Improve your landing pages so people understand your offer, trust you and can contact you easily.
- Track enquiries through to sales, not just clicks and form submissions.
- Follow up consistently with a CRM, reminders and appropriate automated messages.
Advertising brings potential customers to your business, but your sales process decides what happens next. Better response times, communication and follow-up can matter as much as a bigger budget.
9. When should you increase your advertising budget?
Consider increasing your investment when:
- Your campaigns consistently generate qualified enquiries.
- You understand how much it costs to acquire a customer.
- Your acquisition costs are compatible with your profit margins.
- Your business can handle more customers without hurting service quality.
- You have the cash flow to support the increase.
If you don't know which campaigns produce customers, improve your tracking and conversion process first. And don't raise your budget just because competitors seem to spend more: their models, margins and acquisition costs may be completely different.
10. Frequently asked questions
How much should a small business spend on advertising per month in Australia?
A small business might begin with $500–$2,000 per month as an illustrative starting range. The right amount depends on industry, location, profit margins and customer acquisition goals.
Is $500 a month enough for advertising?
It can be enough to test a focused campaign, especially for a business serving a small area. Results depend on competition, advertising costs and your offer's conversion rate.
Should I spend more on Google Ads or Facebook Ads?
Google Ads may suit businesses whose customers actively search for their services. Facebook and Instagram may suit visual content, audience discovery and brand awareness. Let actual campaign performance guide your allocation.
Should advertising costs include agency fees?
Yes, when calculating your total marketing investment. Keep media spend and agency fees separate in reporting so you can see exactly where your money goes.
How long should I run a campaign before deciding whether it works?
It depends on the platform, budget, sales cycle and number of conversions. Judge campaigns on sufficient data, not a few clicks or enquiries.
Should I increase my budget or improve my website?
If your site attracts relevant visitors but generates few enquiries, improving conversion may beat raising spend. If it converts well but has too little traffic, more advertising may be worth considering.
Final thoughts: spend strategically, not simply more
There is no magic budget that guarantees success. The right amount is the one your business can sustain while acquiring customers at a cost that makes financial sense. Start with a realistic budget, choose channels that suit your customers and measure results beyond clicks and impressions.
Advertising is only one part of customer acquisition. Your website, sales follow-up, customer experience and retention all influence your return. Once you know what a customer is worth and what you can afford to pay to win one, setting a budget becomes a far more informed decision.
Not sure where your marketing budget should go?
You don't necessarily need to spend more on advertising. You need a strategy that connects your ads, website and follow-up process to measurable business outcomes.
