The document calculates potential losses from non-buyers at a store with an average daily footfall of 100 people, of which only 40 are buyers. With a product average cost of Rs. 500, the daily loss from the 60 non-buyers is Rs. 30,000. Extrapolating this to a month at 25 days and a year at 12 months, the annual loss from non-buyers is calculated to be Rs. 90,00,000. Increasing conversions by 5% could lead to additional annual sales of Rs. 4.5 lakhs.
