What guest lifetime value means for a restaurant
Guest lifetime value estimates the revenue attached to a relationship over time. A guest spending €65 per visit, visiting eight times a year and remaining active for three years represents €1,560 of estimated lifetime revenue in this simple model.
That is not the same as profit. Food, labour, discounts, acquisition cost and the time value of money are not deducted. The number is best used as a directional tool: it shows why retaining a known guest can be economically different from treating every reservation as an isolated transaction.
Segment before calculating
One venue can have very different guest patterns: weekday regulars, local families, corporate bookers, event guests and seasonal visitors. Calculate them separately when possible. Use booking and point-of-sale data for average spend, then define active-guest windows consistently so visit frequency is not inflated by a short peak period.
A guest profile is not marketing consent
Operational booking data and permission to send promotional messages are different purposes. Apply your privacy notice, access controls, retention rules and consent process.
How to improve lifetime value responsibly
The strongest levers are better experiences, relevant recognition and an easy path back. Direct booking links, accurate preferences, thoughtful post-visit communication and service recovery can improve retention without relying on constant discounts. Staff should see only the guest information needed for their role.
Measure changes by cohort. For example, compare the 90-day repeat rate of first-time direct guests before and after a revised confirmation and follow-up sequence. Avoid claiming that software caused improvement unless the baseline, period and other operational changes are documented.
