You need the estimated gross monthly amount of your pension for your government job not covered by Social Security and the monthly amount of your Social Security benefit as a spouse before the effect of GPO.
Will I be eligible for Social Security retirement benefit based on my own earnings?
Do you have a higher benefit based on your spouse's earnings?
