What percentage of revenue should you spend on marketing?

"What percentage of revenue should I spend on marketing?" is the most common budgeting question I hear from operators — and it's the wrong question to start with. Not because the benchmarks don't exist (they do, and we'll cover them), but because the percentage is a result of good decisions, not a substitute for them. Let's do both: the data, and the better way to think about it.

What the benchmarks actually say

Here's where the credible 2026 data lands:

A few patterns matter for service businesses specifically. Service businesses tend to spend at the higher end because they compete on reputation and relationships rather than a product on a shelf. And smaller businesses spend a larger share — companies under $10M in revenue allocate a notably higher portion of budget to marketing than larger firms, because they're still building the awareness and authority that established players already have.

So if you want the quick answer: 7–10% of revenue is the normal range for a healthy service business, and growth-stage operators often choose to run higher on purpose.

The benchmark tells you whether your number is sane. It can't tell you whether it's right.

Why the percentage is the wrong starting point

Two businesses can both "spend 8% on marketing" and have completely different outcomes — because the percentage says nothing about margins, customer value, or whether the spend is structured. A business running 15% net margins can pour money into growth that would bankrupt a business running 5% margins. A patio builder closing $40,000 projects can afford an acquisition cost that would ruin a business doing $200 service calls.

The percentage is a top-down cross-check. The real budget is built bottom-up, from economics.

The better way: build the budget from unit economics

Four numbers set your real budget:

1. Average customer value. What's a closed job or a customer relationship worth? Use lifetime value where it applies — a retained client is worth far more than a single transaction.
2. Close rate. What share of qualified leads actually become customers? Be honest.
3. Allowable cost per acquisition. Given your margin target, what can you pay to win a customer and still profit? This is the ceiling that keeps you solvent.
4. Lead target. How many customers do you need, and therefore how many leads?

Multiply it through and you get a budget grounded in your business, not an industry average. Then check it against the 7–10% benchmark. If your economics justify 12% and your margins can carry it, the benchmark shouldn't stop you. If they only justify 5%, spending 9% because "that's the average" just funds waste faster.

Count everything — including ad spend

A common mistake: operators compare a $5,000 agency fee to the benchmark and conclude they're under-spending, while ignoring $20,000 a month flowing to Google. Total marketing spend includes ad spend, agency or staff costs, software, and content — everything. When you benchmark, benchmark the whole number. (For context on the ad-spend portion specifically, see the Google Ads playbook.)

The number that matters more than the budget

Here's the shift that changes everything: stop optimizing the size of the budget and start optimizing its structure. A structured 6% will out-earn a chaotic 10% every time, because in a real marketing system every dollar reinforces the others — paid demand feeds conversion, content lowers paid costs, reviews lift both. The question isn't really "how much should I spend." It's "is what I'm spending working as a system, and can I prove it?"

That second half — can you prove it — is what marketing attribution and the right metrics are for. Without them, no budget is the right budget, because you can't tell which part is working.

The bottom line

Spend 7–10% of revenue as a starting sanity check. Build the actual number from your unit economics. Count every dollar, including ad spend. And then put more energy into structuring the spend than sizing it. A diagnosis of where your current budget is working and where it's leaking is exactly what the Growth Blueprint provides.
