To estimate your future spouse's , widow's , or widower's benefits under the GPO, you need two things:- the estimated "gross" monthly amount of your pension from your government job not covered by Social Security.- the estimated monthly amount of your Social Security benefit as a spouse, widow, or widower before the effect of GPO
Can I calculate an approximate amount for my spouse who already has his estimate?
Are you wanting to find the estimated amount of the retirement benefit your spouse would be eligible to receive at when they officially retire?
Yes exactly.
