How Much Should a Small Business Spend on Marketing in 2026?

“How much should we spend on marketing?” is the first question almost every business owner asks us, and the honest answer is: it depends on your margins, your goals, and how fast you want to grow. That’s not a dodge. It’s the whole point. A percentage someone quotes from a survey can’t know your numbers. Here’s how to work out your own.

Start with the math, not a percentage

Rules of thumb like “spend 5–10% of revenue” are a fine sanity check, but they ignore the two numbers that actually decide whether marketing is profitable:

1. Gross margin. What’s left of each sale after the cost of making or delivering it.
2. Customer value. What a customer is worth over time, not just on the first order.

If you sell a $60 product at a 60% margin, each sale leaves $36 to cover marketing and overhead. If customers typically buy three times, that customer is worth roughly $108 in gross profit. That’s your ceiling for what you can afford to pay to win them, before profit.

Work backward from a goal

Instead of picking a budget and hoping, pick a target and do the division:

• Revenue goal from marketing: e.g. $20,000/month
• Average order or deal value: $60 → about 334 orders
• Conversion rate of your website: 2% → about 16,700 visitors
• Target return on ad spend (ROAS): 3x → about $6,700 in ad spend

Now you have a budget tied to an outcome. And you can see the levers: raising conversion rate from 2% to 3% cuts the traffic you need by a third. That’s why we so often start with the website before turning up ad spend.

Split it across “now”, “next” and “later”

A healthy marketing budget covers three time horizons:

• Now (demand capture): Google Search ads, Shopping, retargeting, email to existing customers. These reach people already close to buying. They’re usually the most efficient dollars you’ll spend.
• Next (demand creation): Meta, TikTok and YouTube ads, content, influencers. These introduce you to people who didn’t know they needed you yet.
• Later (compounding assets): SEO, a great website, your email list, brand. Slow to start, cheap to maintain, and they make every other channel cheaper.

Newer businesses tend to lean on “now” and “next” because they need cash flow. Established businesses that under-invest in “later” often find their ad costs creeping up every year.

Don’t forget the non-ad costs

Budgets often only count ad spend. Real marketing also costs:

• Creative: photos, video, design. Ads without fresh creative fatigue fast.
• Tools: email platform, scheduling, analytics, design software.
• People: your team’s time, freelancers, or an agency.

A common mistake is spending on ads but starving creative, then concluding “ads don’t work for us.”

When should you spend more?

Increase spend when all three are true:

1. You’re profitable (or clearly on track) at your current spend.
2. You have enough creative to keep ads fresh as you scale.
3. Your website and follow-up (email, sales process) can handle more leads without dropping them.

Scale in steps, around 20–30% at a time, and watch cost per acquisition. If it jumps and stays up, you’ve found the edge of your current audience or creative. That’s a signal to test new angles, not to give up.

When should you spend less?

Pull back or pause when you can’t measure results. Fix tracking first. Every dollar you spend “blind” makes the next decision harder. Also pull back if you’re losing money on every sale and have no evidence customers come back.

The bottom line

Your marketing budget should be a formula, not a guess: margins and customer value set the ceiling, your goals set the target, and testing tells you where to put the next dollar. If you’d like help building yours, book a free strategy call. We’ll run the numbers with you.
