Franchise Viability Calculator
Most franchise proposals present costs as percentages of turnover. This calculator works the other way — start with what you need to take home, and it shows you the monthly turnover required after the franchisor royalty, the advertising levy, food cost, staff, and rent have all taken their share. Adjust any percentage and the model updates immediately. The royalty stack visualisation shows where every rand of turnover goes before it reaches you — a number that surprises most people evaluating a South African franchise for the first time.
