How much can I save with a railcard?

When buying a railcard, you aim to break even after several trips. But is it really profitable when taking the train from Southampton to Cardiff? Use your calculator, taking into account:

A = the railcard cost (i.e.: £30)

B = average price cut with the railcard (i.e.: 34%)
