Doing MetroCard math

Countless straphangers wonder which MetroCard makes the most sense: weekly, monthly, of pay-as-you-go? If you're struggling to figure out what type of MetroCard you should buy, the MTA has a MetroCard fare calculator on its website to help you come up with the best plan. A 30-day unlimited card is only worth it if you swipe your card at least 47 times in the month, according to the website.
