How Much Should a Small Business Spend on Marketing?

You have seen the rule. Two to five percent of revenue to stay level, ten percent or more to grow.

It is a reasonable sanity check and a poor budget, and for a business your size it has two specific flaws worth understanding before you use it.

Why the percentage rule misleads

It is based on last year. A percentage of revenue tells you what a business your current size typically spends. It says nothing about what it costs to become the size you want.

It cuts spending exactly when you can least afford it. Revenue drops, so the percentage drops, so visibility drops, so revenue drops. The rule is procyclical, and it is at its worst in the quarter you most need it to hold.

Use it as a check at the end, not as the method.

Work backward from the target instead

Four numbers, and you already know three of them.

1. How many extra customers do you want this year? A real number. Twenty-four extra jobs, not "more."

2. What does a customer currently cost you to acquire? Total everything you spent last year to get customers, divided by the customers it got you. If you have never spent anything, use what a lead platform charges you and work from there.

3. Multiply. Twenty-four extra customers at $200 each is $4,800.

4. Divide by twelve. That is $400 a month.

Now sanity check it against the percentage rule. If your target implies twenty percent of revenue, either the target is unrealistic or your cost per customer needs to come down before you scale spending into it.

This method has a property the percentage rule lacks: it produces a number attached to an outcome, so at the end of the year you can tell whether it worked.

The floor

Below the discretionary layer there is a set of things that are not really marketing spend, they are the cost of being a findable business.

• Hosting, domain, and business email
• A site that works and is current
• Your business profile maintained
• Reviews collected steadily

That floor is small, often under a hundred dollars a month plus your own time, and it is the last thing to cut. Cutting into the floor does not save money, it removes you from consideration, and getting back takes months rather than the week it took to cancel.

The mistake that costs the most

Slow month, so marketing goes to zero.

It is the most understandable decision in small business and one of the most expensive, because the effect arrives on a delay. You cut in February, the pipeline empties in May, and by then you are cutting again.

The right move in a slow month is to reduce the discretionary layer and protect the floor. Pause the ads, keep the profile alive, keep asking for reviews, keep the site current. Those cost time rather than money, which is the resource a slow month gives you more of.

Spend it in the right shape

Two adjustments most small businesses should make to whatever number they land on.

Weight it to your season. A landscaper spending evenly across twelve months is wasting the winter and underspending the spring. Front-load into the weeks before your demand arrives, because visibility has to exist before the searching starts.

Keep a test slice. Perhaps ten to twenty percent of the budget on something you have not tried, deliberately, with a decision point at ninety days. Without it you will spend the same money the same way for five years and never find out what else worked.

When the answer is zero

Two situations where spending nothing is correct.

You cannot serve more customers. Adding demand you cannot fulfill produces missed calls, slipped jobs and bad reviews. Fix capacity first.

Your close rate is broken. If you get inquiries and convert almost none, more inquiries will not help. Buying traffic to feed a process that leaks is the most expensive way to discover you had a process problem.

Both are better problems than a marketing problem, and both are cheaper to fix.

The check at the end of the year

One question, and it needs the number you decided at the start.

Did the spend produce the customers it was supposed to produce?

If yes, raise it, because you have found something that converts money into work. If no, the useful next question is which part failed: the channel, the offer, or the follow-up. That is a specific investigation rather than a vague sense that marketing did not work.
