Initial cost of LAPISZ Underwear: RM120 (on average)
Estimate the Lifespan: Period underwear typically lasts between 1 to 3 years. Let’s use an average lifespan of 2 years.
Estimate the Number of Uses : Assume that the underwear is used during each menstrual cycle. If a person menstruates for about 5 days per cycle and uses the underwear for 2x each month, that’s 24 uses per year (2 uses × 12 months). Over 2 years, that's 48 uses (24 uses x 2 years)
Cost Per Wear: RM120 divide by 48 uses = RM2.50 per use
Therefore, the average cost per wear of period underwear costing RM120, with an estimated lifespan of 2 years and used for approximately 2x each month, is about RM2.50 per use or RM0.25-RM0.30 Sen per hour use (8-10 hours uses depending on your flow)
