How Much Should You Spend on Digital Marketing? (2025 Guide)

The #1 question we get from new clients: "How much should I spend on digital marketing?" The honest answer is: it depends — but there are proven frameworks to get the right number for your business.

The Simple Rule: 5–15% of Revenue

The classic marketing budget rule is to spend 5–15% of your annual revenue on marketing. Where you sit in that range depends on your growth ambitions:

• Maintaining current revenue: 5–7%
• Growing 20–50% per year: 8–12%
• Aggressive growth (50%+): 12–20%+
• New business or new product launch: Treat as an investment, not a percentage

Note: This is total marketing spend — including agency fees, ad spend, tools, and content creation.

If You're Just Starting Out ($0–$5K Revenue/Month)

Start lean. Your priorities should be:

• A website that converts: $200–$1,500 (one-time)
• Google My Business optimisation: free — do it yourself first
• One paid channel test: $200–$400/month on Google or Meta
• Skip the monthly retainer until you have revenue to support it

Total: $200–$500/month. Focus on getting your first 10 customers, collecting testimonials, and proving the model before scaling.

Growing Business ($5K–$25K Revenue/Month)

• Paid ads (Google + Meta): $800–$2,000/month
• SEO (if long-term focus): $500–$1,000/month
• Email marketing setup: $200–$500/month
• Agency management fee: $500–$1,500/month

Total: $2,000–$5,000/month. At this stage, you should be seeing 3–8x return on paid channels.

Established Business ($25K–$100K Revenue/Month)

• Paid ads (multi-channel): $3,000–$10,000/month ad spend
• SEO + content: $1,500–$3,000/month
• Email & SMS: $500–$1,000/month
• CRO & analytics: $500–$1,000/month
• Full agency retainer: $2,500–$6,500/month

Total: $8,000–$21,000/month. At this level, marketing should be a predictable growth engine, not an experiment.

The Most Important Number: Cost Per Acquired Customer (CAC)

Don't think in terms of "how much am I spending." Think in terms of CAC vs LTV (Lifetime Value). If you spend $100 to acquire a customer who spends $800 with you over their lifetime — that's a brilliant investment. If you spend $300 to acquire a customer worth $200 — you're destroying value.

Know your numbers. Know what a new customer is worth to you. Then work backwards to what you can afford to spend to acquire them.

How to Evaluate If an Agency Is Worth It

Simple test: ask for their average ROAS (Return on Ad Spend) across similar clients. Anything below 3x (returning $3 for every $1 spent) isn't worth it. We average 3.4x across all clients, with top performers at 6–8x.

Also ask: how do they report? Weekly reports, real-time dashboards, and proactive communication are signs of an agency that's accountable. Monthly PDFs with vanity metrics are a red flag.
