Start with starting customers, new customers, lost customers, repeat customers, order value, visit frequency, margin, retention cost, and locations.
A restaurant customer retention rate calculator should make buyer-owned customer-count and repeat-visit assumptions explicit before teams compare retention work against CAC or loyalty spend.
- Starting customers, new customers, lost customers, repeat customers, order value, visit frequency, contribution margin, program cost, and location count are named before review.
- Buyer-owned POS, loyalty, delivery, attribution, margin, campaign, labor, capacity, and retention assumptions stay separate from market-visible price, menu, promotion, and competitor evidence.
- Calculator output can move into LTV, CAC, marketing ROI, sales analytics, retention reporting, dashboards, exports, or MICT follow-up.
