How Much Should a Small Business Spend on Marketing?

"How much should I spend on marketing?" It is the single most common question we hear from small business owners. And the honest answer, the one most agencies will not give you, is that it depends on where your business is right now, what industry you are in, and what you are trying to achieve. But I am not going to leave you with "it depends." I am going to give you real numbers, real benchmarks, and a framework you can use to set your budget this week.

I have run a digital marketing agency in Brisbane for five years. I have seen businesses waste $50,000 a year on marketing that does not work, and I have seen businesses spend $500 a month and grow faster than anyone expected. The difference is not the dollar amount, it is how strategically that money is allocated.

The Percentage-of-Revenue Rule

The most widely cited guideline is to spend a percentage of your gross revenue on marketing. Here is what the data says for Australian businesses in 2026:

Let me put that in real dollars. If your business turns over $300,000 per year and you allocate 8%, your annual marketing budget is $24,000, or $2,000 per month. If you turn over $500,000 at the same percentage, that is $40,000 per year or about $3,300 per month. These are not huge numbers, but they are enough to run a serious digital marketing program if spent wisely.

What Those Dollars Should Actually Cover

The biggest mistake I see is businesses spending their entire marketing budget on a single channel. They put everything into Google Ads, or everything into social media management, and wonder why results are inconsistent. A balanced marketing budget for an Australian small business should cover multiple areas.

These numbers shift based on your business. A local service business (plumber, electrician, dentist) should weight more toward Google Ads and local SEO. An ecommerce brand should invest more in social media and email marketing. A B2B consultant might focus on LinkedIn content and SEO. The point is: diversify. No single channel should eat more than 40% of your total budget unless you have very strong data showing it delivers.

Tiered Budgets: What You Can Achieve at Each Level

$500/month: The Foundation

At $500 per month, you are working with limited resources, but you can still make real progress. Focus entirely on the highest-impact, lowest-cost activities: claim and optimise your Google Business Profile, set up Google Search Console and start tracking rankings, publish two blog posts per month targeting questions your customers ask, and post consistently on one social media platform (the one where your customers spend their time).

At this level, you are doing the work yourself. That is fine, in fact, it is how most successful small businesses start. The key is consistency. $500/month spent consistently over 12 months will outperform $6,000 spent in one burst.

$1,000 to $2,000/month: The Growth Engine

This is the sweet spot for most Australian small businesses. At $1,000 to $2,000 per month, you can run paid ads alongside organic content, invest in professional email marketing tools, produce quality blog content weekly, and start building a real presence across multiple channels. Most of our clients at Create & Grow Media operate in this range, and it is enough to generate meaningful, measurable growth.

$3,000 to $5,000/month: Scaling Up

At this level, you should be working with a professional, either an in-house marketing person, a freelancer, or an agency. The budget supports advanced strategies: retargeting campaigns, video content, A/B testing, and multi-channel attribution. You have enough data to make smart decisions about where every dollar goes, and you should be tracking cost per acquisition across every channel.

Businesses spending $3,000 to $5,000 per month on marketing should expect to see their customer acquisition costs decrease over time as campaigns optimise and organic traffic compounds. If your cost per customer is going up at this budget level, something is wrong with your strategy, not your budget.

The Australian Small Business Marketing Reality

Understanding the broader context helps you benchmark your own spending. The Australian digital marketing market was valued at nearly USD $13.93 billion in 2025 and continues to grow at 6.9% annually (Expert Market Research). That growth is being driven by small businesses investing more in digital channels, and for good reason.

Here is the reality: 97.1% of Australians are online, and 77.9% use social media regularly (DataReportal). Your customers are online. If your marketing budget does not reflect that, you are falling behind businesses that have already made the shift. At the same time, 63% of microbusinesses still have no web presence (ABS). If you are reading this and already have a website and some marketing in place, you are ahead of the majority.

The cost of doing nothing is real. Every month without a marketing strategy is a month where your competitors are building organic rankings, growing their email lists, and showing up in the places your potential customers are looking. Marketing is not an expense, it is the engine that drives revenue.

Frequently Asked Questions

Is $500 a month enough for marketing? Yes, if you are strategic about how you spend it. At $500/month, focus on organic activities like SEO, content creation, and social media rather than paid ads. The time investment is higher, but the long-term returns are strong. Many of the most successful small businesses we know started at this level and scaled up as revenue grew.

Should I spend more on marketing when business is slow? Counter-intuitively, yes. When business is slow, visibility matters more than ever. The businesses that maintain or increase their marketing during quiet periods are the ones that recover fastest. Cutting your marketing budget when things are slow creates a downward spiral, less visibility leads to fewer customers, which leads to less revenue, which leads to more cuts.

How do I know if my marketing spend is working? Track three numbers: cost per lead (how much you spend to get an enquiry), cost per customer (how much you spend to get a paying customer), and return on ad spend for paid channels. If your cost per customer is less than the profit from that customer's first purchase, your marketing is working. If it takes 2 to 3 months for a customer to become profitable, factor in lifetime value.

Our courses cover all of this in detail, from setting up Google Ads campaigns to building content strategies that drive organic traffic. If you want to get the most out of every marketing dollar, start with the fundamentals and build from there.
