Simple household math: this calculator estimates how many days a box of cotton swabs will last based on your daily usage.
Days Lasting = Swabs Per Box / Swabs Used Per Day
Example
A 500-count box, using 2 swabs per day:
Days Lasting = 500 / 2 = ~250 days
A Note on Safe Use
Most health guidance recommends against inserting cotton swabs directly into the ear canal, since this can push earwax deeper or risk injury to the eardrum - many common everyday uses, like makeup touch-ups or cleaning small spaces, don't carry this same risk.
Buying in Bulk
For households with steady daily usage, this calculation can help decide whether a larger bulk box is worth the lower per-swab cost compared to smaller, more frequently repurchased boxes.
