Xbox Live Renewing Question

[Scythe]

Hi, my live subscription runs out soon. My new 12 month subscription code arrived today. If I redeem the code now, will it activate when my old subscription runs out or start immediately?

It will just add an extra 12 months on to how ever long is left on your current sub

It will just add 12 months onto what you have left....
