WMATA has expanded its new monthly pass program, SelectPass. Now, you can buy a pass for nine different levels of fares based on your travel patterns. What’s right for you? We’ve created a calculator.

SelectPass gives you a monthly pass for the cost of 18 round trips (36 one-ways) at a price you select. You pick a pass at the level of your regular one-way rush-hour fare; any extra trips of the same or lesser value are free, and more expensive ones just cost the difference between that fare and the single-trip fare.

The cost of the monthly SelectPass, therefore, is 36 times the cost of the fare threshold you choose, ranging from $81 for a $2.25 SelectPass to $212.40 for a $5.90 SelectPass. It’s available for every 25¢ increment from $2.25 to $4.00, and also at the maximum fare of $5.90. Is it a good deal for you?

To find out what your savings could be, use the calculator below, which Greater Greater Washington contributor Chris Slatt developed and I adapted and expanded.

We’ve filled it in with an example representing someone who commutes 20 days a month at rush hour between East Falls Church and Farragut West (40 trips at $3.30 each), and does a round trip in the afternoon between Farragut West and Capitol South once a week (eight trips at $1.75 each).  If you don’t know how much your trips cost, go to the Metrorail stations page and click on the station where you’re starting your trip.

How much would you save with a pass?
