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%)

C = average cost for a Southampton Cardiff ticket (i.e.: £40.63)(1)

The first step is to divide A by B: this will show you the budget from which the card will be efficient. You can now divide that number by C. It will give you the approximate number of trips needed across the year to start saving money.

In our example, A/B = £30/34% = £88.00. Then, 88/£40.63 = 2.17. Your railcard will be profitable if you're doing around 3 trips from Southampton to Cardiff (one way journey).
