Simple Budget Formulas You Can Use Today
1) % of Revenue (fast & common)
Marketing Budget = Annual Revenue × Target %
Example: $1,200,000 revenue × 8% = $96,000/year (~$8,000/month)
2) CAC / Payback Math (performance‑driven)
Target CAC ≤ LTV ÷ 3 and Payback Period ≤ 12 months
Example: Average order value $120, 30% gross margin, 3 purchases/year → LTV ≈ $108. Target CAC ≤ $36.
3) Bottom‑Up (goal‑based)
Start with revenue target → back into leads and required spend using historic CVR and CPL.
Example: Need 40 new customers/month at CAC $150 → budget ≈ $6,000/month.
Recommended Channel Mix
| Channel | Budget % | When to Emphasize |
|---|---|---|
| Meta Ads (FB/IG) | 20–35% | Visual products, local lead gen, retargeting |
| Google Search & PMax | 20–30% | High intent, bottom‑funnel capture |
| YouTube / Short‑Form Video | 10–20% | Education, consideration, brand lift |
| SEO & Content | 10–20% | Compounding organic demand over time |
| Email/SMS & CRM | 5–10% | Retention, LTV, promotions |
| Testing & Creative | 5–10% | UGC, new hooks, landing pages |
Reallocate monthly based on actual CPA/CAC, ROAS, and payback. Winner channels earn more budget; laggards are iterated or paused.

FAQs: Small Business Marketing Budgets (2025)
How much should a small business spend on marketing?
Mature SMBs typically spend 5–10% of annual revenue. Startups or businesses in aggressive growth mode plan 10–20%, especially during launches or peak seasons.
How do I set a marketing budget if I’m just starting?
Use a goal‑backed plan: set monthly revenue targets → estimate required customers → apply a target CAC (e.g., ≤ LTV ÷ 3) → that dictates the minimum monthly budget to test and scale.
What’s a healthy CAC and payback period?
A common rule: CAC ≤ LTV ÷ 3 and payback in ≤ 12 months. Product‑market fit and margins matter—tighter margins require lower CAC and faster payback.
How should I split my spend across channels?
Starter mix: Meta 20–35%, Google 20–30%, Video (YT/Shorts) 10–20%, SEO/Content 10–20%, Email/SMS 5–10%, Testing 5–10%. Reallocate monthly to top performers.
What if my budget is tiny—like $1,500/month?
Prioritize one high‑intent channel (e.g., Google Search) + one demand gen channel (Meta) + email capture. Tight creative and a strong landing page can punch above your weight.
How do I know when to scale?
Scale when a campaign consistently hits your CAC/ROAS targets for 2–4 weeks and your operations can fulfill demand. Increase 20–30% at a time and watch metrics.
Where do creative and landing pages fit into the budget?
Hold 10–20% for testing new creatives, audiences, and landing pages. Creative fatigue is real—fresh hooks often drive cheaper clicks and conversions.
Should I pause SEO if I need short‑term sales?
Don’t. Keep a baseline SEO investment (10–20%). It compounds over time and reduces your paid dependency. Use paid channels to drive short‑term pipeline.
