A lot goes into the decision of whether to buy your home or rent it. But the main factor for most people is cost.

The New York Times has a nifty calculator that analyzes whether you should by or rent. Enter a little bit of info about the home you’re interested in and then it will calculate how long you’d need to rent it before it becomes more worthwhile to have bought it.

Obviously, this can’t make the decision for you, but it might save you a bit of time and mental effort as you look at your budget and make this important decision.
