Hello NightDragon;
http://www.ssa.gov/OACT/anypia/anypia.htmlThe detailed calculator at the above link gave me a very accurate (within a dollar a month) projection.
You do have to download it in order to use it. I haven’t checked the latest version, but the old version required the completion of several different drop-downs. They were found in one of the “top bar” items. Until you complete them, the calculator is useless. Be very careful that you follow the instructions for each separate drop-down. Be sure that all amounts are in US dollars. The result will also be in US dollars. And, you will be paid in US dollars, but the deposit to your bank account in the UK (once a month) will be in Pounds Sterling, computed at the daily exchange rate (if it is to be paid in the UK).
You have the option to enter future scenarios. If you’re still working, it’s an estimate of what you think you will contribute between now and when you stop contributing (or age 66?). Once it’s completed, you can vary your estimates and print off different scenarios for comparison. Or, in your case, how different UK pension payouts may vary the US Social Security amounts.
You will also need your last yearly statement from the Social Security Administration. If you don’t have one to hand, you can use your own records if they are accurate for all your contributions.
The calculator utilizes/calculates “bend points”. The Social Security Administration’s computer uses the first bend point to determine the basic amount of the reduction for WEP. If you have 30 or more years of “substantial earning for US Social Security”, you will have no reduction in benefits. That’s a very rough description, but there are many factors that go into the calculation, including different ways of doing the calculation itself.
The most important figure is on the first page of the report. You are looking for the “Primary Insurance Amount”. That’s what you receive in US dollars per month. I’ve taken a quick glance at my records to refresh my memory. I lost 35% of what the total amount would have been without applying WEP.
Please, I’m basing this on how the calculator used to work a few years ago. It may have changed. But I imagine the result would be much the same.
