I’ve been buying the 30-day unlimited MetroCard since I moved to NYC. It hasn’t saved me much money (and probably actually cost me more than single rides), but it’d nice to know I can jump on the subway anytime I want.

The cost of the monthly card has just gone up from $70 to $76. Thanks to Grant Barrett’s MetroCard Cost Analysis Report, I realize I should start buying the $20 single-ride card instead. I take 4 trips each Tuesday, but rarely ride more than 6 or 8 times throughout the rest of the week. Even if I bought a $7 Daily Unlimited Card on Tuesdays, it would only make those rides cost $1.75 each instead of $1.67 with the $20 card.
