Could someone explain to me how and ira account works? My husband and I are 21 and we want to start to put away money for retirement while we're still young. I've heard of 401k and ira accounts but I don't really understand how it all works. My husband has a retirement plan already with his job but we want something else as well. Could someone tell me what would be the smartest and most beneficial way to save our money for the future?
