The MTA unveiled a new online tool geared toward making sure subway riders get the most bang for their buck.
The Authority says the "MetroCard Calculator" will help customers plan new card purchases and figure out the most efficient way to refill a card.
When you enter a dollar amount for the purchase of a new MetroCard, or a planned refill, the calculator figures out the number of rides you get for the money and any remaining balance on the card.
The calculator will also offer suggestions for which card would best suit your travel needs.
To try it out, go to mta.info/NYCT/metrocardcalculator.
