I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
First, I know that the only reason you are receiving $3300 per month is because you are either significantly older than your mid to late 60's, or you took advantage of the delayed retirement credit of 8% per year for delaying your benefits after full retirement age, or a combination of both.
If your wife applies for a spouse benefit, and she is 66 or older, then she will be entitled to up to 50% of the value of your social security benefit that you could have taken at age 66----which as of 2016 is about $2650 per month----which would make her spouse benefit at most about $1,350 per month..
If she retires before full retirement age, she will be penalized about 6% for each year she retires early if she takes her own benefit, and about 3.5% per year for early retirement if she takes a spouse benefit.
