How Much Should You Spend on Marketing? A Straight Answer

"How much should I spend on marketing?" is one of the most common questions business owners ask — and most answers are unhelpfully vague.

Here's the straight version, including the benchmarks, and the two numbers that matter far more than any percentage.

The benchmark answer

As a rule of thumb, most small businesses spend between 5% and 20% of revenue on marketing. Where you land depends on your stage and how aggressively you want to grow:

• Early-stage or launching something new: 10–20% of revenue. You're buying awareness and, just as importantly, learning what actually converts.
• Growing and established: 7–10%. The focus shifts to building repeatable acquisition and optimising what works.
• Mature and steady: 4–7%. Enough to defend and grow position without over-investing.

B2C businesses generally sit higher than B2B, because consumer buyers need more constant brand-building and acquisition.

These are starting points, not gospel. Which brings us to the part most people skip.

Why the percentage is the wrong question

A percentage of revenue tells you what's typical. It tells you nothing about whether your marketing is actually working.

If every $1 you put into marketing reliably brings back $4 in profit, why would you cap it at 8% of revenue? You'd spend as much as you could fund. And if your marketing loses money, even 3% is too much.

The right question isn't "what percentage should I spend?" It's "what is a customer worth, and what can I afford to pay to get one?"

The two numbers that actually decide your budget

Customer acquisition cost (CAC)

Total marketing and sales spend, divided by the number of new customers it produced. If you spent $10,000 and won 20 customers, your CAC is $500.

Lifetime value (LTV)

The total profit a customer generates over the life of the relationship — not just the first sale. A customer worth $400 on the first job but who comes back for years and refers others might be worth $5,000+.

Once you know both, the decision gets simple. If a customer is worth $5,000 and costs you $500 to acquire, that's a 10:1 return — and a strong argument to spend more, not less. A healthy LTV:CAC ratio is often cited as 3:1 or better.

A practical way to set your budget

1. Start with a benchmark for your stage (say 8–10% if you're growing).
2. Measure your CAC and LTV honestly — most businesses have never done this.
3. Follow the return. Pour money into the channels with the best payback and cut the ones that don't earn it.
4. Give it time. Some channels (SEO, referrals, brand) compound over months. Judge them on trend, not a single week.

The mistake that wastes the most money

It isn't spending too little or too much. It's spending without measurement — running ads, boosting posts and paying retainers with no idea which dollar produced which customer.

Money spent blind isn't a marketing budget. It's a donation. Track the return, and the "how much should I spend" question mostly answers itself.
