How Much Should a Small Business Spend on Marketing in 2026?
The 'spend 10% of revenue on marketing' rule doesn't work for small businesses. Here's what to actually spend, where to spend it, and what return to expect.
Google "how much should I spend on marketing" and you'll get the same answer everywhere: "5-10% of revenue." For a business turning over £200,000, that's £10,000-£20,000/year. But this advice is designed for mid-sized companies with marketing departments, not for a sole trader or small team trying to grow.
The Real Answer
The right marketing budget isn't a percentage — it's a return on investment calculation. How much is a new customer worth to you? How much can you afford to spend to acquire one? That's your marketing budget.
Let's work through some real examples:
Trades (Plumber, Electrician, Builder)
- Average job value: £2,000-£5,000
- Cost to acquire a customer: should be under £200
- Sensible monthly marketing budget: £49-£149
- Expected return: 1-3 new jobs/month = £2,000-£15,000 revenue
Professional Services (Accountant, Solicitor, IFA)
- Average client value: £2,000-£5,000/year (recurring)
- Client lifetime: 3-10 years = £6,000-£50,000 lifetime value
- Sensible monthly marketing budget: £149-£349
- Expected return: 1-2 new clients/quarter = £8,000-£20,000/year additional revenue
Healthcare (Dentist, Physio, Chiropractor)
- Average patient value: £300-£1,500/year
- Sensible monthly marketing budget: £49-£149
- Expected return: 5-10 new patients/month
Where to Spend It
The channel allocation depends on your business type, but here's a framework that works for most UK small businesses in 2026:
| Channel | % of Budget | Why |
|---|---|---|
| Marketing platform/tools | 40-60% | The engine that generates and sends everything |
| Google Ads (if applicable) | 20-30% | Immediate visibility for high-intent searches |
| Content/SEO | 10-20% | Long-term organic traffic (often included in platform) |
| Social ads | 10-20% | Targeted reach beyond organic |
What NOT to Spend On
Based on what we see from thousands of small businesses, these are the biggest wastes of marketing budget:
- Leaflet drops: Response rates under 0.5%. Cost per lead: £50-200+
- Local magazine ads: Unmeasurable. No way to track ROI
- Social media managers: £500-£1,500/month for someone to post 3x/week. AI does this for £49/month
- Full-service agencies: £1,500-£3,000/month for junior work you could automate
- Branded merchandise: Pens and notepads don't generate leads
The £49/Month Starting Point
If you're currently spending nothing on marketing, don't jump to £500/month. Start with a £49/month platform that gives you email campaigns, social media posts, landing pages, and SEO content — all generated by AI from your website. See what happens over 3 months. Measure the results. Then scale up based on what's working.
The businesses that waste money on marketing are the ones that spend big without measuring. The businesses that grow are the ones that start small, track everything, and double down on what works.
Measuring Your Return
Whatever you spend, you need to track these three numbers:
- Cost per lead: Total marketing spend ÷ number of enquiries
- Cost per customer: Total marketing spend ÷ number of new customers
- Customer lifetime value: Average revenue per customer × average years they stay
If your cost per customer is less than 10% of their lifetime value, your marketing is working. If it's higher, something needs to change — usually the channel, not the budget.
