Customer lifetime value and repeat rate for restaurants: how to calculate them

Most restaurant marketing is built around new customers: the grand opening, the ad, the influencer visit. But when Toast looked at its restaurant data for the first quarter of 2026, it found that 7% of guests drive up to half of all order volume. Square’s data puts a regular (someone who buys on four or more separate days in a year) at six times the annual revenue of a one-time customer.

Two numbers tell you whether your business is building those regulars: repeat rate and customer lifetime value. Here’s how to measure both with the tools you probably already have, and how to use them to decide what you can afford to spend on marketing.

The visit that matters most is the second one

Paytronix, which runs loyalty programs for more than 800 restaurant brands, found that first-time guests come back less than half the time, but guests who reach a fourth visit come back 95% of the time. Guests with ten or more visits are worth 27 times as much as one-time visitors. (Their data comes from loyalty members, who are more engaged than the average guest, so real-world numbers for a small restaurant will be lower.)

The practical point: most of your risk sits between visit one and visit four. A new customer who comes back twice is on their way to being a regular. A new customer who never comes back cost you whatever you spent to get them.

How to measure your repeat rate

Repeat rate is the share of customers who come back within a set window. Pick a window that fits how often people buy from you: 30 days for a coffee shop, 60 or 90 days for a dinner spot.

You don’t need special software. Both of the big point-of-sale systems track this if you set them up:

• Square builds a free customer profile automatically when a customer pays with a card that has their name on it. Its default “Regulars” group is anyone with three visits in the last six months, and “Lapsed” is a regular who hasn’t been back in six weeks. You can change both. The Customer Insights report shows visits and average spend per customer.
• Toast builds guest profiles from online orders, emailed or texted receipts, loyalty, reservations, and marketing sign-ups. It has preset segments for regulars and lapsed guests, and a Guest Insights view that shows new versus repeat guests and your retention rate.

One caveat: both systems only count guests they can identify. Cash payers and anyone who never gives an email or phone number drop out of the math, so your measured repeat rate will run lower than the real one. The fix is to capture contact details wherever it’s natural: online orders, preorders, digital receipts, and your email list.

How to calculate customer lifetime value

Customer lifetime value (CLV) is how much a typical customer is worth to you over the whole time they keep buying. The simplest version that works for a restaurant:

The margin part matters. Revenue isn’t what you get to keep. Here’s a worked example with made-up numbers:

That gap is why repeat business matters so much. It also tells you how much you can sensibly spend to win a customer. If one in three new customers becomes a regular like this, the average new customer is worth about $140 in margin (a third of $381 plus two-thirds of $19), so spending $20 to $30 to win one makes sense. If almost nobody comes back, the average is closer to $19, and even $10 is a lot.

There are more precise formulas that account for the chance a customer leaves each year and discount future money back to today. Different textbooks don’t even agree on which version is right. For a small restaurant, the simple version is enough to make good decisions.

What about the famous retention statistics?

You’ve probably seen two numbers quoted everywhere. Both are worth understanding before you repeat them.

• “A 5% increase in retention increases profits by 25–95%.” This comes from Bain & Company’s Frederick Reichheld, published in Harvard Business Review in 1990 and 2000. It’s real research, but it covered industries like banking, insurance, and e-commerce. None of it was restaurant data.
• “Acquiring a customer costs 5 to 25 times more than keeping one.” This is from a 2014 HBR article that didn’t cite a primary source, and the author said the figure depends on which study you believe and what industry you’re in.

There’s also a well-known counterpoint. Research from the Ehrenberg-Bass Institute found that growing brands grow mainly by winning more new buyers than they lose, not by cutting losses alone. The honest takeaway: you need both. New customers fill the top, and retention decides how much each one is worth.

Do loyalty programs actually work?

The evidence says yes, with some caveats about who’s measuring:

• Circana found loyalty members make 22% more restaurant visits a year than non-members, and loyalty traffic is now nearly 40% of all restaurant visits, double 2019.
• Toast found that joining a loyalty program moved a guest’s return rate from 7% to nearly 30%.
• 52% of adults already take part in restaurant loyalty programs, and 81% said they’d join one at a favorite restaurant (National Restaurant Association, 2024).

A loyalty program doesn’t have to be an app with points. For a small restaurant, a list of regulars who hear about things first, get invited to events, and are thanked by name can do the same job.

Email and text: the cheapest retention tools you have

Across 3.6 million campaigns from restaurants and cafes, MailerLite measured an average email open rate of 44% and a click rate of about 1%. (Opens are inflated by Apple Mail, which I explained in what a 60% email open rate looks like.) Square reports that its sellers who use text message marketing see 21% more repeat visits on average.

The message that matters most is the one right after a first order. At Buon Cibo, every early customer got an email asking what they thought. It turned first-time buyers into people who felt heard, which is most of what gets someone to visit number two.

Put it to work

1. Capture an email or phone number with every order you can: online, preorders, digital receipts.
2. Pick a repeat window and measure your repeat rate every month.
3. Send a personal thank-you and a question after every first purchase.
4. Give first-timers a specific reason to come back within the window.
5. Watch your lapsed list and reach out before they’re gone for good.
6. Calculate lifetime value and use it to set a ceiling on what you spend to win a customer.
