How much should a startup spend on marketing?

Many 2026 guides suggest a startup spend 12–20% of revenue on marketing, counting ad spend, fees, creative and tools. Large-company surveys put the average lower, at 7.8–9.0%. A consumer brand buying growth can afford more if its margin allows: at a 50–60% contribution margin, the math supports 25–40%. Set your number from margin and a target MER, not a flat percentage.

What percentage of revenue should a startup spend on marketing?

Spend the share of revenue your contribution margin can carry after covering fixed costs and the profit you need. Common guidance is 12–20% of revenue. In Wadabu's illustrative scenarios for growth-stage consumer brands with 50–60% contribution margins, the margin math supports 25–40% while the brand is buying growth. Whether you should spend at that level depends on your cash and how quickly new customers pay back.

A flat rule such as "spend 10%" ignores two things: how much each sale leaves after costs, and how fast you want to grow. A brand with an 80% margin can spend far more than one with a 35% margin and still make money.

What do marketing budget benchmarks say?

Large surveys put average marketing spend between 7% and 12% of revenue, depending on the business model. The Gartner 2026 CMO Spend Survey of 401 marketing leaders found budgets averaged 7.8% of company revenue, up from 7.7% in 2025. Most respondents were at companies with over $1 billion in revenue, so treat it as an enterprise benchmark.

The CMO Survey, run by Duke University's Fuqua School of Business, Deloitte and the American Marketing Association, surveyed US companies in January 2026. Among the 154 respondents (of 308) who answered the spending question, the mean was 9.0% of revenue and the median 5%. Its 2026 highlights report breaks this out by business model:

The same report finds budgets run higher at smaller companies and at companies with more of their sales online. Subgroups in a survey this size are small, so use these figures as reference points rather than targets. Most respondents already have brand awareness and repeat buyers. A startup without a repeat base pays for nearly every customer, so its share often runs higher until reorders build up.

What counts in a startup marketing budget?

Count every dollar you spend to get and keep customers, not just ad spend.

• Ad spend: Meta, Google, TikTok and any other paid media.
• Fees: agency retainers, freelancers and a fractional marketer.
• Creative: photo and video shoots, UGC creators, design work.
• Tools: email platform, reviews app, analytics and attribution software.

Add in-house marketing salaries if you have them. In this article, MER means fully loaded MER: total revenue divided by all of those costs. Some brands calculate MER on media spend only, which gives a higher number. Either works if you compare like with like. For how retainers and packages are priced, see what's in a digital marketing package.

How do you set a marketing budget from contribution margin?

Subtract what you need to keep for fixed costs and profit from your contribution margin before marketing. What's left is the most you can spend on marketing, as a share of revenue. One divided by that share is your target MER.

Contribution margin is what each sales dollar leaves after product cost, shipping, fulfillment, payment fees, discounts and returns. If you haven't worked yours out, start with how to calculate contribution margin.

The amount you keep has to cover overhead like salaries, rent and software, plus any operating profit you want. Contribution margin sets how much you can spend. Cash runway and CAC payback set how fast you can use it. A funded brand can wait months for customers to pay back. A bootstrapped brand usually needs payback inside a few weeks. You can run these numbers in the marketing budget calculator.

What does a marketing budget look like at $30k, $100k and $300k a month?

Here are three hypothetical brands with the same 50% contribution margin before marketing, each at a different stage. The creative and tools lines are illustrative. The fee lines use Wadabu's month-to-month pricing: $3,000 for one service, and a $10,000 bundle of all four services that covers ad management on up to $30,000 in ad spend, plus 10% of spend above that.

"Left after marketing" is not net profit. Overhead and taxes still come out of it. At $30,000 a month, the fee is paid ads alone: $3,000, since 10% of $7,500 in ad spend is only $750. At $100,000, it's paid ads plus email at $6,000. At $300,000, it's the bundle at $10,000 plus 10% of the $24,200 in ad spend above $30,000, for $12,420.

Fees take 25% of the launch budget, 20% at growth and about 17% at scale. Small brands pay a higher share in fixed costs, so they should buy fewer services and add more as revenue grows.

How much of a marketing budget should go to ad spend?

In these illustrative budgets, ad spend takes 60–75% of the total. If ad spend falls well below half of your budget, that's often a sign you're paying for more services or software than revenue supports. There are exceptions: SEO-led brands, wholesale-heavy brands and brands that run on frequent new creative can sensibly spend less on media.

There is also a minimum. With too little ad spend, platforms can't collect enough conversions to optimize. The minimums by platform are in how much ad budget a startup needs. If your margin math can't reach that minimum yet, put the money into email, SEO and your site first.

How should a pre-revenue startup budget for marketing?

Budget from cash runway and test goals, not a percentage of revenue you don't have yet. Decide what you need to learn before launch, such as which audience converts, what a first customer costs and which offer works. Then set a fixed test cap you can afford to lose, for example a set amount over 60 days, and stop or adjust when it's spent. Once sales come in, switch to the margin method above.

How should a marketing budget change as you grow?

Raise spend in steps and keep a step only when the numbers hold. Blended MER alone isn't enough to approve an increase, because returning customers can prop it up while new-customer results get worse. Check three numbers after each step:

• Blended MER at or above target for a few weeks.
• New-customer CPA and the contribution from first orders.
• Payback period on new customers, within what your cash can fund.

Recheck margin when product cost, shipping or discounts change, since your target MER moves with it. As repeat revenue grows, raise the MER target so the share of revenue spent on marketing comes down. For why MER is a better budget guide than platform ROAS, see what MER is and why it beats ROAS.

Final thoughts

Start with your contribution margin, decide what you need to keep for fixed costs and profit, and let that set your marketing budget and MER target. Benchmarks from large companies are reference points, not a plan. To see what each service costs month-to-month, check Wadabu's pricing.

Frequently asked questions

How much should a small business spend on marketing?

Many 2026 guides suggest a small business spend 12–20% of revenue on marketing, above the 7.8–9.0% averages in Gartner and CMO Survey data. A consumer brand with a 50–60% contribution margin can spend 25–40% while buying growth, if cash runway and customer payback allow it.

How much should an ecommerce brand spend on marketing?

An ecommerce brand should set its marketing budget from contribution margin and a target MER. At a 50% margin, keeping 20% of revenue for fixed costs and profit means spending up to 30% of revenue on marketing, a 3.33 MER. B2C product companies averaged 12.0% in The CMO Survey's 2026 edition.

Is 10% of revenue enough for marketing?

Ten percent of revenue is close to the average for established companies, which reported 7.8% to 9.0% in 2026 surveys. For a startup without many repeat customers, 10% is often too little to fund ad spend, creative and fees, unless growth comes mainly from word of mouth, wholesale or organic search.

What should be included in a marketing budget?

A marketing budget should include ad spend, agency and freelancer fees, creative production, marketing software and any in-house marketing salaries. Counting only ad spend makes marketing look cheaper than it is. The full total is the figure to use for fully loaded MER, which is total revenue divided by total marketing spend.
