average number tampons required per cycle
You're instructed to change your tampon every 4 to 8 hours, so we'll use 6 hours as an average. A box containing 36 tampons costs $7 at Walgreens. 1 tampon every 6 hours = 4 tampons per day x 5 days of a period = 20 tampons per cycle x 456 periods = 9,120 tampons. At 36 tampons per box, that's 253.3 boxes x $7 = $1,773.33. Panty liners. Some women prefer pads and some combine tampons with panty liners as a backup. For our purposes, we'll say that women use an average of five liners per period. A box containing 36 panty liners costs $7 at Walgreens. 5 liners per cycle x 456 periods = 2,280 pads.
