How is Suica Monthly pass calculation?

I have Suica card with monthly pass in a range between two stations, Can I enter in one station in this range and go beyond the range of these two stations and still use Suica at the exit gate? how the fare will be calculated?

Can I enter in one station in this range and go beyond the range of these two stations and still use Suica at the exit gate?
Yes, as long as you stay in the Tokyo area.

how the fare will be calculated?
the shortest distance on the lines.
If you have a SUICA with commutation ticket from A to C, and you use it from A to E, you must pay for C to E.

in Suica area (enter to exit : same area) touch usual!
as over range fare adjusted automatically.
JR to privete lines station too.

if your Suica charged not enough over range fare could not before enter.

1) exist "fare adjustment machine[のりこし精算機/Norikoshi-seisan-ki]" stn
