How Much Should a Small Business Spend on Marketing in 2026?

"How much should we spend on marketing?" It's the question every business owner asks — and the one that gets the most frustrating answer: "It depends."

Well, it does depend. But that doesn't mean you're left guessing. There are clear frameworks, sensible rules of thumb, and UK-specific benchmarks that can give you a solid starting point. Let's cut through the noise and give you a practical answer you can actually use.

The Rule of Thumb: Revenue Percentage

The most widely used guideline is to set your marketing budget as a percentage of your gross revenue. But the percentage varies depending on your goals:

• Maintenance mode (5-10% of revenue): You're happy with your current growth rate and want to maintain your market position. You're focused on retention, brand presence, and steady lead flow.
• Growth mode (10-20% of revenue): You're actively trying to grow — entering new markets, launching new products, or scaling aggressively. You need to invest to build awareness and capture market share.

For a UK SME turning over £500,000 per year, that's between £25,000 and £100,000 annually — or roughly £2,000 to £8,300 per month. For a sole trader on £100,000 revenue, it's £5,000 to £20,000 per year.

These aren't arbitrary numbers. They reflect the reality that marketing is a compounding investment. Underspend and you become invisible. Overspend without strategy and you burn cash. The sweet spot is intentional investment matched to clear goals.

What Can You Actually Do at Different Budget Levels?

Theory is one thing. Here's what marketing budgets actually look like in practice for UK small businesses in 2026:

The numbers above are illustrative, but they reflect real-world pricing in the UK market. The key insight? Even at £500/month, you can do meaningful marketing — if you focus on the right things.

The 70/20/10 Rule for Budget Allocation

Once you've decided how much to spend, the next question is where to spend it. The 70/20/10 framework is a simple, effective way to allocate your budget:

• 70% on proven channels. These are the tactics you know work for your business — the things that consistently drive leads and revenue. For most SMEs, that's a combination of SEO, Google Ads, and email marketing.
• 20% on emerging tactics. Channels or formats you've tested with promising early results. Maybe LinkedIn content is starting to generate inbound enquiries, or video marketing is getting traction. Give these room to grow.
• 10% on experiments. New ideas, untested platforms, creative campaigns. Most will fail — and that's fine. The ones that work become tomorrow's 20% allocation.

This framework stops you from being too conservative (putting everything into one basket) or too scattered (trying everything at once). It's how smart businesses scale without gambling.

What to Prioritise on a Tight Budget

If you're just getting started or your budget is genuinely tight, here's the priority order. Focus on the first item before moving to the next:

1. A website that converts. Not just a pretty brochure — a website with clear messaging, a strong call to action, and a way to capture leads. This is your 24/7 salesperson. If it's not pulling its weight, nothing else will work properly either.
2. Google Business Profile. It's free, and for local businesses it's one of the highest-ROI activities you can do. Fully optimise it, add photos, get reviews, post updates.
3. SEO fundamentals. Target 5-10 keywords your ideal customers are actually searching for. Create a page or blog post for each one. This takes time to compound but costs relatively little to start.
4. Email marketing. Build a list from day one. Even a simple monthly newsletter keeps you top of mind and drives repeat business.
5. Focused social media. Pick ONE platform where your audience actually spends time. Do it well. Don't try to be everywhere.

That's a solid foundation you can build for under £500/month, much of it through your own effort. As revenue grows, your budget grows with it.

Challenging the "We Can't Afford Marketing" Mindset

Here's the uncomfortable truth: you can't afford not to market. Every business that's "too busy for marketing" is one quiet month away from a cash-flow crisis. Word of mouth is wonderful — until it dries up. Referrals are great — until your biggest referral source retires.

Marketing isn't an expense. It's the activity that creates your future revenue. The businesses that understand this invest consistently, even when times are good. The ones that don't are the ones scrambling when the pipeline runs dry.

If you genuinely have zero budget, start with free activities: optimise your Google Business Profile, ask happy customers for reviews, post valuable content on LinkedIn, start building an email list. These cost nothing but time — and the compounding returns are significant.

The biggest mistake isn't spending too little. It's spending without a plan. A marketing audit will show you exactly where your current spend is working and where it's being wasted — so you can make every pound count. And if you're worried about common digital marketing mistakes eating into your budget, those are worth addressing first.

The Bottom Line

There's no single "right" number for your marketing budget. But here's a framework you can use today:

1. Calculate 5-10% of your revenue (maintenance) or 10-20% (growth)
2. Allocate using the 70/20/10 rule
3. Prioritise the foundations first (website, Google Business, SEO, email)
4. Review and adjust quarterly based on what's actually working

The worst approach is no approach at all. Set a number, commit to it, measure the results, and adjust. That alone puts you ahead of the vast majority of UK small businesses.
