People in serious relationships tend to spend so much time together that it seems silly to pay two rents, so it feels natural to move in together. But the move may not always end up saving money.

Alpha Consumer examines a Pew report (PDF) on the economics of living together and draws some interesting conclusions about the economics of shacking up.

One factor that comes into play is children, which can cause one partner to stay home with the kids, drastically reducing the couple’s earning power. Another factor is debt that one person can bring into a household, sullying the economic health of the couple. Mismatched economic priorities can also lead to financial trouble, and jointly purchased assets can be tough to divide in the event of a breakup.

If you’ve lived with a boyfriend or girlfriend, what were the hidden costs of your arrangement?
