I'm Doug, and I'm very sorry for your loss. My goal is to provide you with excellent service today.
As for your survivor benefit, it will be about 27% less if you take it now as opposed to when you reach 66, however waiting past 66 will not make a difference in how much you will receive.
If you don't need the money right now, you would be better off waiting----waiting to 66 if possible, but even if you take it early, closer to 66 is better for you.
If you are working now, keep in mind that if you take a survivor benefit now and earn more than about $15,000 a year, you will be penalized and you will have to repay social security some of the money they will be paying you.
