This may help - it's what I use at folkinfo to try to assist people when using our transpose thing. In your case, just find your starting key, e.g to use what Noreen said find G and if you move up 2 frets, move 2 to the right.

A, Bb, B, C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B, C, C#, D, Eb, E, F, F#, G, Ab, A
