The Four Numbers Your Restaurant Marketing Actually Depends On

Walk into any restaurant industry event and you will hear the same handful of suggestions on repeat. Post more on Instagram. Get on every delivery app you can find. Partner with the brewery down the block. Build the email list. Launch a loyalty program. Run more promotions on the slow nights of the week.

Some of this advice is genuinely useful for some restaurants. Some of it will quietly destroy your margins while your top line keeps growing and you wonder why your bank account isn't moving in the same direction. The trouble is that nobody can tell you which is which from the outside, because the answer depends entirely on your specific numbers, and most restaurants are not tracking the ones that would actually answer the question.

The industry benchmark says you should spend three to six percent of revenue on marketing, with newer restaurants pushing higher into the five to ten percent range while they fight for awareness. That figure tells you roughly how big your budget should be. It does not tell you whether the money you are already spending is doing anything for you. The four numbers below are the ones that will.

1. Customer acquisition cost, by channel

Take everything you spent on a single channel last quarter and divide by the number of new customers it actually produced. The result is your customer acquisition cost for that channel, and you should know it for every channel you are funding.

The hard part is attribution, and you are not going to get it perfectly clean. You also do not need to. What you need is something directionally honest. Train your hosts and servers to ask every new diner how they found out about the restaurant, log the answers in your POS or in a paper notebook for two solid weeks, and run that exercise once every quarter. After two or three rounds, you will have enough real data to compare your channels with confidence.

When owners actually go through the work, they tend to find the same pattern. One or two channels are doing roughly eighty percent of the real acquisition, while three or four others are bleeding money out of pure habit. The habits are usually what need to go first.

2. Contribution margin per customer, by channel

A guest who walks in and orders an appetizer, two entrees, a bottle of wine, and dessert is a completely different financial event than the same dollar amount of orders coming through a third-party delivery app. The two can look similar when you compare them on revenue alone, but the dollars that actually make it to your bank account are nowhere close to each other.

Contribution margin is what is left after you cover the variable costs of serving that customer, including food, packaging, platform fees, and credit card processing. You need to run the calculation separately for dine-in, for takeout, and for each delivery platform you have signed onto. The numbers are not going to match.

This calculation matters more right now than it has in years. Third-party delivery platforms typically take between fifteen and thirty percent of every order, and those rates have been climbing as the major platforms continue to reinvest in promotions and member programs. On a fifty-dollar delivery order under a higher-tier plan, roughly fifteen dollars is already gone before you have paid for food, labor, or a single piece of packaging. Most restaurants in this country operate on a net margin between three and nine percent, which means the math on delivery gets uncomfortable in a hurry.

This is why the blanket advice to "get on every delivery app" is wrong for most restaurant concepts. Pizza, wings, and fast casual operations can usually carry the commission because their food costs are lower and their menus are designed for that kind of channel. A full-service neighborhood restaurant often cannot, and signing on with three platforms back to back simply gets you three steady streams of orders that lose money on every single ticket.

3. Repeat rate, by acquisition channel

A new customer who walked in because a friend recommended the place is worth substantially more to you than a new customer you paid to acquire through a half-off promotion. The first one tends to come back without much prompting. The second one almost never does.

If your POS or reservation system tracks repeat visits, and almost all of them do these days, pull your repeat rates at thirty, sixty, and ninety days after the first visit. Then segment those rates by how each customer originally found you. Healthy restaurants tend to land somewhere around sixty to seventy percent repeat behavior across the customer base overall, but the real story is the spread between your different channels.

The cheapest acquisition channels almost never produce the strongest repeat rates. Owners chase them anyway, because the cost figure is sitting right in front of them while the lifetime value figure takes actual work to calculate. The result is that you end up paying once for a long string of customers who were never going to come back a second time.

4. Marketing spend as a percent of revenue

The three to six percent benchmark averages a lot of very different operations together. Quick service tends to land between three and six percent. Casual dining runs slightly higher at four to seven. Fine dining sits between four and eight. Ghost kitchens and delivery-only concepts often push six to ten percent or higher, because they have no walk-in traffic to lean on. Digital channels are now consuming between sixty and eighty percent of the typical restaurant marketing budget, which is a separate conversation about mix that most owners also need to be having.

If you are spending one percent of revenue on marketing, you are almost certainly starving the business and leaving real growth on the table. If you are spending eight percent and your revenue isn't moving, throwing more money at the problem will not fix anything. What you have is an allocation problem rather than a budget problem, and the only useful question to ask is which of your current channels needs to be cut.

Bringing the four together

These four numbers are most useful when you read them as a single picture rather than four separate metrics. Acquisition cost tells you what you are paying for new customers. Contribution margin tells you what each of those customers is actually worth once they walk in or place an order. Repeat rate tells you whether you are buying real customers or simply buying transactions. The percentage of revenue going to marketing tells you whether you are even playing at the right scale to begin with.

When you have all four in front of you, the popular advice stops sounding like a default set of moves and starts looking like a series of real decisions that only make sense for some restaurants and not others. The question worth asking yourself is no longer "what marketing should I be doing." That version of the question has a thousand possible answers, and most of them will be wrong for your specific restaurant. The version worth asking is "what is each of my current channels actually worth to me." That version has only one real answer, and it is already sitting inside your numbers waiting for you to find it.

Where StarPoint Advisory comes in

Most restaurant owners do not have the time to pull this kind of analysis apart cleanly on their own. Calculating acquisition cost by channel, working out the real contribution margin on each delivery platform, segmenting repeat rates by source, and benchmarking your marketing mix against the right concept-specific numbers all takes serious work and a clear-eyed look at your P&L.

That is what we do at StarPoint Advisory. We sit down with your actual numbers, run the kind of analysis most owners genuinely do not have time for, and come back with a short list of specific decisions you can act on inside a month. The first consultation is free, and if you walk away with even one decision worth making, the call will have paid for itself many times over.
