How much should a restaurant spend on marketing?
The right marketing budget is not a fixed percentage of revenue, it is whatever amount keeps Customer Acquisition Cost within the target range for the restaurant's category and keeps the ratio of customer lifetime value to CAC at 3:1 or better.
Most restaurant owners try to answer this question with a percentage pulled from an industry rumor. The better question is not how much to spend, but what each dollar spent is producing. Customer Acquisition Cost (CAC) is total marketing spend divided by the number of new customers that spend produced. One owner spent $3,200 on marketing in a month and gained approximately 180 new customers, putting CAC at $17.78. That single number is more useful for budget decisions than any revenue percentage, because it shows what growth actually costs.
What is Customer Acquisition Cost and why does it decide the marketing budget?
Customer Acquisition Cost is total marketing spend divided by the number of new customers that spend generated, and it should set the budget rather than a guess based on revenue.
Owners who track food cost to the penny often cannot say what it costs them to bring one new guest through the door. Two mistakes cause this. First, not every marketing cost gets counted: delivery platform commissions, comped food for influencers, and the hours a manager spends on social media are all marketing spend, even though they rarely get logged as such. Second, owners divide spend by total customers instead of new customers, which produces a meaningless number since it is mostly measuring guests who were already coming back on their own.
What is a good CAC for a restaurant?
Target CAC varies by restaurant type: quick service and fast casual should aim for $5-15, casual dining for $10-25, fine dining for $25-50, and catering for $50-150 because of its higher order values.
| Restaurant Type | Target CAC |
|---|---|
| QSR / Fast Casual | $5-15 |
| Casual Dining | $10-25 |
| Fine Dining | $25-50 |
| Catering | $50-150 |
A catering CAC of $80 is not automatically a failure, and a casual dining CAC of $80 almost certainly is. The category sets the benchmark, and the benchmark is what the marketing spend should be measured against, not a flat percentage applied across every restaurant type.
Results are not typical and will vary with your business, your market, your team and how much of the work you actually do. Client figures on this site come from recorded interviews and are dated. Nothing here is a guarantee of revenue, profit or growth.
What is the LTV to CAC ratio and why is 3:1 the target?
LTV to CAC compares what a customer is worth over a year to what it cost to acquire them, and the target is a ratio of at least 3:1, since anything lower means marketing costs more than it returns.
A customer who visits 3 times a year and spends $45 per visit has an annual lifetime value of $135. If the CAC to acquire that customer is $18, the ratio is 7.5:1: every $18 spent generates $135. That is a channel worth funding further. Compare that to a CAC of $60 for a customer who only visits once and spends $45. That customer cost more to acquire than they generated, and scaling that channel scales losses, not profit. The lesson sets 3:1 as the floor. Below that, the marketing is inefficient. Above 5:1, the restaurant might actually be under-investing in growth and leaving acquisition dollars on the table.
How do you find which marketing channel is wasting money?
CAC has to be tracked by channel, not as a single blended number, because a blended average can hide a channel that is working brilliantly next to one that is losing money on every customer it brings in.
The same overall marketing budget can produce wildly different results depending on where it goes. An influencer comp that costs $50 in food but reaches 40,000 people and drives 20 new visits works out to a $2.50 CAC. A delivery platform promotion that costs $500 in discounts and brings in 15 new customers works out to a $33.33 CAC. Same category of spend, completely different efficiency.
This is exactly what played out for one Founders Board member. He was spending $1,200 a month on a local community manager running events and social media, with no idea what it was actually producing. Once CAC was broken out by channel, those community events were costing roughly $80 per new customer, while two influencer visits he had barely tried were costing $4 per new customer. He shifted $800 of that budget into influencer outreach and kept the rest for retention events, which is a different job than acquisition. Within 60 days his blended CAC dropped from $35 to $14, and new customer volume nearly doubled. None of that reallocation happens without first seeing the numbers by channel.
What mistakes make a restaurant's marketing budget look smaller than it is?
The three recurring mistakes are forgetting hidden costs like delivery commissions and staff time, relying on a single blended CAC instead of tracking by channel, and judging CAC without comparing it to lifetime value.
- Forgetting hidden costs: delivery app commissions are marketing spend, and so are the hours a manager spends each week on Instagram. Anything designed to bring in customers counts.
- Relying on blended CAC only: a blended average of $20 can hide an influencer CAC of $3 sitting next to a paid ads CAC of $45. Without tracking by channel, the worst performer keeps getting funded.
- Ignoring lifetime value: a $30 CAC looks expensive until it is clear that customer returns 12 times a year. CAC without LTV context does not mean anything on its own.
The CAC Discovery Sheet used inside the Scaling Engine OS™ walks through listing every channel's spend, estimating new customers per channel, calculating CAC per channel, setting a target CAC by restaurant type, and then flagging the clear winner and the clear loser. Founders Board members get a licence to that same system, which is the tool that produced the 60-day result described above.
