How Much Should a Business Spend on Marketing?
The definitive 2026 guide. Real benchmarks by stage, industry, and revenue, plus the three levers that actually set your number — written by an operator who runs 32 companies using these ratios, not a consultant guessing from a survey.
US businesses average 9.5% of revenue on marketing in 2026 (Gartner CMO Spend Survey). But the average is a trap. The right number for your business depends on three levers: growth target, target CAC, and gross margin. A 70% gross margin SaaS can profitably spend 25%. A 25% gross margin manufacturer dies above 6%.
Use the benchmarks below as sanity checks. Use the formula below to actually set your number. Then book a free 30-minute call at markcmo.com/book and I will model it for your specific business in real numbers.
Why "X% of Revenue" Rules Fail (and What to Do Instead)
The internet is full of articles telling you to spend "5% of revenue" or "10% of revenue" on marketing. These are not wrong. They are useful starting points. But they hide three things that matter more than the percentage itself:
- Gross margin determines what you can actually afford. A 70% gross margin software business and a 25% gross margin manufacturer have completely different marketing-spend capacity at the same revenue. A 12% marketing spend on the software business leaves 58 points of contribution to fund the business. A 12% spend on the manufacturer leaves 13 points — usually below breakeven once operations are loaded.
- Growth target determines what you should spend. A business growing 5% per year and a business growing 50% per year need radically different marketing budgets even at the same revenue, gross margin, and industry. Growth costs money — specifically, it costs the customer acquisition cost (CAC) of every new customer multiplied by the number of new customers you need to hit the growth target.
- LTV:CAC determines what marketing produces. A 3:1 LTV:CAC business gets back $3 in lifetime value for every $1 spent acquiring a customer. A 5:1 business gets $5. A 1.5:1 business is dying. Your marketing spend is not an expense — it is an investment with a measurable return. You should spend more if the return is high and less if the return is low. The percentage of revenue is downstream of these dynamics, not the cause.
This is why every "what is the right marketing budget" article you have read so far has been unsatisfying. The percentages are real averages but they do not tell you what to do. The rest of this page is the actual framework.
The Marketing Budget Formula
Five inputs. One formula. Run this for your business in 15 minutes and you will know your real number, not the industry average number.
1. New revenue needed = Current revenue × Growth target %
2. New customers needed = New revenue / Average customer value (ACV or AOV)
3. Target CAC = LTV ÷ Target LTV:CAC ratio (3:1 for SaaS, 5:1 for e-comm)
4. Gross marketing spend = New customers needed × Target CAC
5. Total marketing budget = Gross marketing spend × 1.25 (overhead: tools, content, brand, people)
RESULT = Marketing budget for next 12 months
Worked example: $10M B2B SaaS growing 40%
2. New customers needed = $4M / $5,000 ACV = 800 new customers
3. Target CAC = $15,000 LTV / 3 = $5,000 CAC ceiling (use $1,500 in mid-funnel paid; $5K loaded with sales)
4. Gross marketing spend = 800 × $1,500 = $1.2M direct marketing spend
5. Total marketing budget = $1.2M × 1.25 = $1.5M
= 15% of revenue.
Compare that 15% to the B2B SaaS industry average of 11-15%, and the number is at the top of the range — which is correct, because 40% growth is at the top of the realistic range for a $10M ARR B2B SaaS. The formula and the industry benchmark agree.
Now run the same formula for a $10M e-commerce business growing 20%:
2. New customers needed = $2M / $80 AOV / 1.4 purchases per year = 17,857 new customers
3. Target CAC = $200 LTV / 4 = $50 CAC ceiling
4. Gross marketing spend = 17,857 × $50 = $893K direct marketing spend
5. Total marketing budget = $893K × 1.25 = $1.12M
= 11.2% of revenue.
Different math, different number, both correct for their model. This is why blanket rules fail.

Where to Allocate Your Marketing Budget
Once you have the total number, the next question is the channel mix. The honest answer is that the right mix is set by your ICP and your CAC math — not by an industry average. But there are reasonable starting allocations by business type:
B2B SaaS marketing budget allocation
- Demand generation (paid search, paid social, outbound, ABM): 35-45%
- Content + SEO + product marketing: 20-25%
- People (in-house team, fractional CMO, agencies, contractors): 20-25%
- Tools and technology (CRM, marketing automation, analytics, enrichment): 10-15%
- Brand and PR: 5-10%
E-commerce marketing budget allocation
- Paid acquisition (Meta, Google, TikTok, programmatic): 50-65%
- Email + lifecycle marketing: 8-12%
- Influencer + affiliate: 8-15%
- Content + SEO: 5-10%
- Brand + creative production: 8-12%
- Tools and tech: 5-8%
Local services marketing budget allocation
- Local SEO and Google Business Profile: 25-35%
- Paid local (Google LSA, Meta local): 25-35%
- Reviews and reputation: 10-15%
- Referral programs and partnerships: 10-15%
- Content + website: 10-15%
- Direct mail and offline (where relevant): 5-15%
How to Know If You Are Overspending
Signs your marketing spend is too high relative to return:
- LTV:CAC below 3:1 (SaaS) or 4:1 (e-commerce). You are paying more to acquire customers than they return over their lifetime. If this lasts more than 12 months it kills the business.
- CAC payback period over 24 months for SaaS, over 12 months for e-commerce. You are tying up cash too long. Even if LTV:CAC eventually works out, you cannot fund growth.
- Marketing spend growing faster than pipeline growth. Diminishing returns are kicking in. Time to optimize, not scale.
- Channel saturation — you are spending more on Google Ads but click costs are rising faster than conversion volume. You have maxed the channel and need to diversify.
- Internal team spending more time managing the agency than selling. Your account director and your VP of marketing are in 6 hours of agency meetings per week. The agency is now a cost line, not a value line.
How to Know If You Are Underspending
Signs your marketing spend is too low:
- Pipeline coverage below 3x quota. Your sales team has less than 3x their target in pipeline at the start of each quarter. Either the marketing-generated pipeline is too small or sales-sourced pipeline is propping it up unsustainably.
- Growth rate below industry median for your stage. If B2B SaaS at your ARR typically grows 30-50% per year and you are growing 15%, you are likely underspending on demand generation.
- Competitors visible everywhere you look online; you are invisible. SEO results, paid ads, podcasts, conferences, LinkedIn — if your competitor shows up 5x for every 1 of you, the spending ratio is reflecting that.
- Sales team complaining about lead volume not lead quality. When sales says "we don't have enough leads," that is usually a marketing-spend signal. When sales says "the leads suck," that is usually a targeting / ICP signal.
- You cannot describe your marketing strategy in one paragraph. If marketing strategy is "we do some Google ads and some content," you are underspending on strategic ownership — i.e., you need a fractional CMO before you need more channel spend.
Strategic Spend vs Execution Spend
Most companies under-allocate to strategy and over-allocate to execution. The right split depends on whether your business has the foundation built:
| If Your Business Is... | Spend on Strategy | Spend on Execution |
|---|---|---|
| Pre-PMF, no clear ICP | 70-80% | 20-30% |
| Post-PMF, scaling first 2 channels | 40-50% | 50-60% |
| Multi-channel, growing 30%+ YoY | 20-30% | 70-80% |
| Mature, optimizing | 15-20% | 80-85% |
"Strategy spend" includes: fractional CMO retainer, ICP research, positioning work, brand strategy, channel diagnostic, vendor selection, internal team development. "Execution spend" includes: paid media, content production, design, email sending, tooling, ad management.
This is why Mark Gabrielli's MarkCMO model fits growth-stage companies so well — the fractional CMO retainer ($8K-$15K/mo) is the strategy spend, and the WETYR team is the execution spend at production rates. The split is transparent on the invoice.
How MarkCMO Models Marketing Budgets
Every MarkCMO engagement starts with a budget model in week one. Here is what is in it:
- Revenue target by quarter for the next 4-8 quarters. What does the CEO/board need to see?
- ICP segmentation — typically 2-3 priority ICPs, each with its own LTV, CAC ceiling, and channel mix.
- CAC math per ICP — what does it cost today, what does it need to cost to hit the LTV:CAC target, and how do we close the gap?
- Channel-level forecast — for each active channel, projected spend, expected leads/MQLs, expected pipeline, and expected revenue at conversion benchmarks.
- Strategic vs execution split — explicit allocation of dollars to MarkCMO + WETYR strategy, dollars to channel execution, dollars to tools, dollars to brand.
- Sensitivity analysis — what if conversion rate is 20% lower than benchmark? What if CAC is 30% higher? Where do we cut first?
- Quarterly review checkpoints — what would have to be true for us to keep spending in this channel? What would force us to kill it?
This model becomes the artifact the CEO takes to the board. It also becomes the accountability framework for the fractional CMO — every quarter, the model gets compared to actuals, and the model gets revised.
