indicates the clear winner per row. Ties and missing data are not highlighted.
How winners are chosen
Lower is better for investment, liquid capital, franchise fee, royalty and ad-fund rates, SBA charge-off rate, and owner turnover.
Higher is better for disclosed revenue and owner earnings, verdict score, total units, net unit growth, and franchisee contacts. For the letter grade, A ranks highest.
A row is highlighted only when one brand clearly leads. Ties are never highlighted, and missing data never counts as a win. Some rows (earnings-metric type, loan counts, contract terms) are informational and have no winner.
These figures come from FDDs of different years (2025, 2026). Costs, fees and unit counts change from one filing to the next, so the older column may be out of date.
