A defensible marketing budget falls out of three figures: what a customer is worth to you, how many more you could service, and what you can afford to pay to acquire one. Businesses that pick a number first and work backwards end up defending the number rather than the outcome, which is why so many budgets get cut the moment cash tightens.
The number that usually gets picked
Three methods account for almost every marketing budget in a small business, and all three share the same flaw.
- A percentage of revenue. Borrowed from published averages, usually somewhere between two and ten percent. It describes what other companies spend, which tells you nothing about whether spending it would work for you.
- Whatever the competitor appears to spend. Estimated from how often you see their advertising, which is a poor proxy, since you are not the audience their targeting is aimed at.
- Whatever is left after everything else. The most common method by a distance, and the reason marketing budgets vanish in exactly the quarters when demand needs support.
Each produces a number without producing a reason. When the year is reviewed, nobody can say whether the amount was right, because there was never a standard to judge it against.
The three figures that do set a budget
What a customer is worth
Start with average job value, then extend it. A furnace replacement is one number. The same customer on an annual service plan for eight years, plus the two neighbours they refer, is a very different number. Most trades and service businesses undervalue themselves here by looking only at the first invoice.
How many more you could actually service
The constraint nobody writes down. If you can absorb six more jobs a month before quality slips or you need another crew, then a campaign producing thirty is not a success, it is a scheduling problem and a reputation risk. Capacity sets the ceiling on sensible spend.
What you can afford to pay for one customer
Take the gross margin on an average customer, decide what share of it you are willing to trade for growth, and that is your ceiling per acquisition. A business with $2,400 gross margin per customer willing to spend a fifth of it can afford roughly $480 to win one. Multiply by the customers you want and can service, and the budget has produced itself.
Where the money should sit
Once you have a number, the split matters as much as the total. A useful division has three parts.
| Portion | What it covers |
|---|---|
| Foundation | The site that receives the traffic, hosting, local search presence, and the photography and copy that make any of it persuasive. Underfunding this makes everything downstream more expensive. |
| Demand | The work that brings people in: search, content, advertising, and the campaigns tied to your busy seasons. |
| Measurement | Tracking, call attribution, and the time to read it. Small in dollars, and it is what turns next year's budget conversation into arithmetic rather than argument. |
The order matters. Spending on demand before the foundation is sound means paying to send people to a page that does not convert, and then concluding the channel does not work. We see it constantly, and it is one of the reasons a website audit is usually the cheapest first purchase a business can make.
The costs that get forgotten
- Hosting and maintenance. Modest annually, and non-negotiable. A site that goes down during your busy month costs more than a year of proper hosting.
- Photography. A single half-day shoot of real work outperforms years of stock imagery, and it is a one-time cost that keeps paying.
- Copy. Someone has to write the service pages. If that person is you, at eleven at night, the cost is real even though it never appears on a statement.
- Your own time. Hours spent managing tools and reading dashboards are hours not spent quoting work. Price them honestly when comparing doing it yourself against having it handled.
What changes as the number grows
Budgets behave differently at different levels, and knowing which band you are in prevents a lot of wasted effort.
- Below roughly $1,000 a month: one channel, done properly, plus a foundation that converts. Anything wider is spread too thin to measure.
- Between $1,000 and $3,000: a primary channel with a supporting one, consistent content, and real measurement behind both.
- Above $3,000: multiple channels can run at once, and the constraint shifts from money to coordination, which is the point at which having one accountable owner stops being optional.
None of this requires a large budget to start. It requires knowing which of the three figures above you do not currently have, because that is the gap that makes every subsequent decision a guess.
Having the conversation properly
The conversation takes an hour and needs four numbers in front of you: average customer value, gross margin, current monthly enquiries, and the capacity you could fill tomorrow. Most owners have all four somewhere and have never put them on the same page.
What comes out is a figure you can defend to a partner, a bank, or yourself in a slow quarter, along with a clear view of what it should produce and by when. That is a very different object from a number chosen because it felt about right.
Frequently asked questions
How much should a small business spend on marketing?
There is no correct percentage. The defensible figure comes from what a customer is worth, how many more you can service, and what share of your margin you are willing to trade to win one. Two businesses with identical revenue can have very different correct answers.
What is a reasonable cost per lead?
It depends entirely on customer value. A business earning $200 per customer and one earning $6,000 cannot use the same benchmark. Work out what you can afford per acquisition first, then judge any quoted cost per lead against that rather than against an industry average.
Should marketing budget be a percentage of revenue?
It is a convenient shorthand rather than a method. Percentages describe what other companies did without accounting for your margin, your capacity, or your competitive position, which are the three things that actually determine what spending will return.
What should be funded before advertising?
The site that receives the traffic, reliable hosting, and accurate local search listings. Advertising into a site that does not convert produces a clear result: you pay for visitors and learn nothing except that the channel appeared not to work.
How do I know if the budget is working?
Agree in advance what it should produce and over what period, then measure enquiries and their quality rather than traffic. If nobody stated the expected outcome at the start, the review at the end becomes a matter of opinion.
Can a business start with a very small budget?
Yes, provided it is concentrated. A small budget spent properly on one channel with a converting site behind it will outperform the same amount divided across five channels every time, because none of the five gets enough to produce a readable result.
